In order to better understand the present application, the related art will be described below.

Stacking techniques are to physically or logically bind together multiple network devices to improve reliability, performance, or management efficiency. However, stacking techniques have drawbacks such as low reliability of the unified control plane of the device, difficulty in upgrading, wasted ports for lateral connections, etc., and in order to solve these problems, de-stacking techniques have been developed. The unstacking technology is a network architecture optimization method and aims to avoid or reduce problems and limitations caused by the traditional stacking technology through specific configuration and technical means.

In a unstacking network applying unstacking technology, the server side typically configures the interface aggregation in a dynamic aggregation manner (e.g. dynamic link aggregation mode 4), i.e. the server may be provided with a logical interface, which may be composed of a combination of physical interfaces of a plurality of network devices. For example, as shown in fig. 1, the server may bind (bond) physical network interfaces (such as ethernet cards) of two LEAF switches, which may each be connected to two SPINE (SPINE) switches, into one logical interface through an ethernet channel bonding technique, forming a SPINE network architecture.

Meanwhile, the LACP (Link Aggregation Control Protocol ) configuration to the two leaf switches may be kept consistent, including the same System identification (System ID) and Priority (Priority) settings, but different Port identification (Port ID) settings. Wherein the LACP is used to combine multiple physical network links into one logical link to increase bandwidth and provide redundancy. LACP is part of the IEEE 802.1AX standard, which allows network devices (e.g., switches and routers) to automatically negotiate and manage link aggregation, ensuring that data flows are evenly distributed among multiple links, thereby improving network performance and reliability.

The purpose of the above design is to make the server treat the two leaf switches as one device through the LACP negotiation mechanism, thereby optimizing network traffic management. The two leaf switches start the ARP local proxy function, configure the unified three-layer gateway interface MAC address, and simultaneously enable ARP direct connection routing. In addition, the routing information can be synchronously routed to the whole network through a border gateway protocol (Border Gateway Protocol, BGP), so that consistent understanding of each device on the network topology is ensured, and the network stability is further enhanced.

In the above architecture, the server may send address resolution protocol messages (also referred to as ARP messages) to a plurality of network devices through a plurality of physical interfaces and ethernet, thereby implementing mapping from IP addresses to MAC addresses.

However, ethernet is a best effort switching network technology, and packet loss or transmission failure may occur when the network is busy. When the logic interface of the server side is congested, the situation of packet loss of ARP messages may occur, so that ARP table entries of the mapping relation between the IP address and the MAC address stored by the leaf switch side are not updated in time. Because the flow from the leaf switch to the server depends on the ARP direct-connection routing function, all the network flow from the switch to the server is lost under the condition that ARP list items are not updated in time, and the network flow can not be recovered to be normal until the ARP list items at the switch side are recovered. Therefore, the method of sending the address resolution protocol message in the related art is difficult to ensure the stability of the network service.

In view of the foregoing, it is desirable to provide an address resolution protocol message sending method, apparatus, computer device, computer readable storage medium and computer program product, so as to improve the stability and reliability of network services under a unstacked network.

In an exemplary embodiment, as shown in fig. 2, an address resolution protocol messaging method is provided, and the method is applied to a server for illustration, and includes the following steps S201 to S204. Wherein:

step S201, determining a plurality of member interfaces aggregated through a server logic interface, wherein the plurality of member interfaces respectively correspond to different message receiving devices.

In a specific implementation, the multiple member interfaces can be aggregated through the server logic interface, and the multiple member interfaces respectively correspond to different message receiving devices. In some embodiments, the plurality of member interfaces may be physical network interfaces (such as network cards) corresponding to two or more switches, and the plurality of member interfaces may be aggregated into a logical interface of the server, also referred to as a bond interface, by an ethernet channel bonding technique.

Step S202, according to the network monitoring data of each member interface, determining the network congestion index corresponding to the logic interface, and according to the network monitoring data, adjusting the preset initial index threshold to obtain the current index threshold.

In a specific implementation, network monitoring may be performed on each member interface in the logical interfaces to obtain network monitoring data, where the network monitoring data may be data reflecting network states of the member interfaces and/or links corresponding to the member interfaces.

Then, on the one hand, the network congestion condition of the logical interface can be evaluated by combining the network monitoring data of each of the plurality of member interfaces, so as to obtain a network congestion index corresponding to the logical interface, wherein the network congestion index is also called a congestion index (C), and can reflect the network congestion condition of the logical interface.

On the other hand, the preset initial index threshold value can be adjusted by combining the network monitoring data of each of the plurality of member interfaces to obtain the current index threshold value, wherein the initial index threshold value can be used as a reference standard to be compared with the current network congestion index of the logic interface. In some embodiments, the initial index threshold may be one, and the network state may be divided into two parts by comparing the network congestion index with a single index threshold, and of course, the initial index threshold may be multiple, and by comparing the network congestion index with multiple index thresholds, multiple (such as three or more) network states may be more carefully identified, so as to facilitate adoption of more carefully diverse ARP message scheduling strategies.

Step S203, if the network state is determined to be normal according to the network congestion index and the current index threshold, the address resolution protocol message is sent to the message receiving devices according to the normal processing mode.

In some related technologies, for example, according to the principle of flow HASH (HASH), the server may select one of the plurality of member interfaces to send an ARP message according to a related algorithm, for example, if a logical bond interface of the server is configured by two 25G member interfaces, and the bond interface is used as an external interface, when sending the ARP message, the related technology may select one of the bond interfaces to send the ARP message, which may cause that ARP entries of the plurality of message receiving apparatuses are not synchronized.

In this way, the server can start the multi-sending function (such as the double-sending function) of the ARP message, so that the server can respectively send the same ARP message to a plurality of message receiving devices through each member interface.

In some embodiments, the unstacking network may employ an S-MLAG (Split Multi-Link Aggregation Group ) scheme, which is an enhanced link aggregation technique for improving network redundancy and bandwidth that allows aggregation of links of multiple switches into one logical group for higher bandwidth and better failure recovery capability, and in an S-MLAG configuration, links may provide redundant paths across multiple switches to ensure that network traffic can continue to be normally transmitted in the event of a failure of a single switch or link, which may be applied to data centers and large enterprise networks, helping to improve reliability and scalability of the network. In the S-MLAG scheme, a plurality of message receiving devices are completely independent at the control level, and the synchronization of routing, ARP and MAC (media access control) items can be realized by a server for information multiple, namely when the server sends ARP requests and receives response information of the message receiving devices, the server can send the ARP requests and receive the response information through all member interfaces aggregated by a logic interface, so that the synchronization of ARP and MAC items of unstacking devices is realized.

Based on this, in this embodiment, after the network congestion index and the current index threshold are obtained, the network congestion index and the current index threshold may be compared, and the network state may be determined according to the comparison result. If the network state is determined to be normal according to the network congestion index and the current index threshold, the address resolution protocol message can be sent to the message receiving devices according to a normal processing mode preset by the ARP message, that is, when the network state is normal, the ARP message can be sent to all the message receiving devices through all the member interfaces, for example, when the server is connected to two leaf switches, the ARP dual-sending function can respectively send the same ARP message to the two leaf switches. The normal processing mode can be understood as processing the address resolution request and the response according to the standard workflow and rules, that is, the ARP message is forwarded normally without additional measures.

Step S204, if the network state is determined to be the congestion state according to the network congestion index and the current index threshold, the address resolution protocol message is sent to the message receiving devices for a plurality of times according to the preset time interval through the member interfaces.

If the network state is determined to be the congestion state according to the network congestion index and the current index threshold, the address resolution protocol message can be sent to a plurality of message receiving devices through a plurality of member interfaces for a plurality of times according to a preset time interval. In other words, in this embodiment, when it is determined that the network is relatively congested, the address resolution protocol packet may be sent to each packet receiving device through each member interface periodically and repeatedly, so that ARP packets may be prevented from being lost or expired due to light network congestion by periodically sending ARP packets to a plurality of packet receiving devices repeatedly when the network is congested. In some examples, the frequency of ARP timing transmissions may be determined based on network load, e.g., the frequency of transmissions may be increased if the member interface network load is low, and decreased if the network load is high to reduce additional impact on the network load, e.g., ARP messages may be transmitted at preset time intervals of a few seconds to tens of seconds.

The address resolution protocol message sending method comprises the steps of determining a plurality of member interfaces aggregated through a server logic interface, wherein the plurality of member interfaces respectively correspond to different message receiving devices, determining a network congestion index corresponding to the logic interface according to network monitoring data of the plurality of member interfaces, adjusting a preset initial index threshold according to the network monitoring data to obtain a current index threshold, further sending the address resolution protocol message to the plurality of message receiving devices according to a normal processing mode if the network congestion index and the current index threshold are determined to be normal, and sending the address resolution protocol message to the plurality of message receiving devices according to a preset time interval through the plurality of member interfaces if the network congestion index and the current index threshold are determined to be congestion. In the embodiment, on one hand, the current index threshold value is dynamically adjusted according to the network monitoring data, so that flexible response to different network congestion conditions can be realized, the network congestion state is prevented from being determined by adopting a fixed threshold value, the ARP message scheduling mode can be adjusted in time in various network states, on the other hand, the network state is monitored in real time and the network congestion conditions and the index threshold value are used for controlling the ARP message scheduling mode, and the network is transmitted according to a normal mode when the network state is normal, so that the additional influence on the network load is reduced, and meanwhile, the delay and the packet loss caused by the network congestion are reduced according to the preset time interval when the network state is congested, thereby effectively maintaining the stability and the reliability of communication in the unstacked network.

In an exemplary embodiment, in step S202, determining, according to the network monitoring data of each of the plurality of member interfaces, a network congestion index corresponding to the logical interface may include the following steps:

In practical application, the state of the logic interface and each member interface in the logic interface can be continuously monitored, flow statistic data can be periodically read, and network monitoring indexes such as delay information and the like can be estimated by using a network tool, so that the network state can be comprehensively known.

Specifically, in this embodiment, according to the network monitoring data of each of the plurality of member interfaces, the packet loss rate, the bandwidth utilization rate and the delay jitter of the plurality of member interfaces in the monitoring time may be determined. In one embodiment, the packet loss rate, bandwidth utilization and delay jitter of the multiple member interfaces may be obtained by:

(1) And acquiring network card flow data of each member interface in the logic interfaces. For example, during the monitoring time T, the data reception situation (RX) of the member interface, such as the interface traffic (rx_bytes), may be obtained using virtual files, which in one example may be proc, net, dev or other virtual files, which may provide network interface statistics, covering both reception and transmission aspects. Further, a flow difference value may be calculated within the monitoring time T, the flow difference value=rx_bytes_end-rx_bytes_start, where rx_bytes_end is the interface flow at the end of the monitoring time T and rx_bytes_start is the interface flow at the beginning of the monitoring time T.

(2) The bandwidth utilization is calculated from the traffic difference, and in one example, the bandwidth utilization U may be calculated as follows:

u= (traffic difference/time interval T)/total bandwidth x 100%

(3) And in the monitoring time T, acquiring the number of messages (RX_packets) and the number of lost packets received by the interface by using the virtual file. Then, a packet loss number difference drops _diff= drops _end-drops _start may be calculated for the monitoring time T, and a total number of packets rx_packets_diff=rx_packets_end-rx_packets_start received for the monitoring time T may be calculated. Wherein drops _end is the packet loss number at the end of the monitoring time T, drops _start is the packet loss number at the beginning of the monitoring time T, rx_packets_end is the packet number at the end of the time T, and drops _start is the packet number at the beginning of the monitoring time T.

(4) And calculating the packet loss rate. In an example, the packet loss rate L may be calculated as follows:

l= (packet loss number difference drops _diff/total packet number rx_packets_diff) ×100%

(5) Multiple ICMP requests are made to a target host using a network tool (e.g., a network diagnostic tool ping) to obtain delay data for the network. The probe packet is transmitted a plurality of times within the Time T and its Round-Trip Time (RTT) is recorded. The round trip time RTT, also referred to as round trip delay, refers to the total time required for a data packet to be sent from a source device to a destination device and back to the source device, and may be used to measure network delay, which may include, for example, the transmission time of the data packet and the delay of any routing, processing, or queuing.

(6) The delay jitter J may then be calculated from the round trip time, e.g. n round trip times x _i may be recorded in T times, the delay average μ is calculated, and the delay jitter J is then calculated as follows:

In some embodiments, for each member interface, the packet loss rate, bandwidth utilization, and delay jitter corresponding to each member interface may be calculated in the manner described above. Then, according to the packet loss rate, the bandwidth utilization rate and the time delay jitter of the plurality of member interfaces, the network congestion index corresponding to the logic interface can be determined.

In some embodiments, the overall packet loss rate, the overall bandwidth utilization rate, and the overall delay jitter may be determined according to statistical processing results of the packet loss rates, the bandwidth utilization rates, and the delay jitter of the plurality of member interfaces, and then the network congestion index C may be calculated according to the manner shown below.

Wherein, C is network congestion index (index), U is bandwidth utilization rate, L is packet loss rate, J is delay jitter, W _U 、W_L、W_J is weight coefficient of bandwidth utilization rate, packet loss rate and delay jitter, the influence of bandwidth utilization rate, packet loss rate and delay jitter on network congestion is different, and the weight coefficient can be adjusted according to specific conditions. In some embodiments, the bandwidth utilization rate, the packet loss rate and the delay jitter are indexes for measuring whether the network is congested, the high and low of the bandwidth utilization rate reflects the load condition of the network, the high and low of the packet loss rate reflects the stability and reliability of the network, and the high and low of the delay jitter reflects the stability and consistency of the network.

In this embodiment, by integrating the three indexes, the network congestion index can comprehensively reflect the network state in multiple dimensions, and a reliable basis is provided for subsequently adjusting the ARP message scheduling policy, so that the ARP message scheduling manner can effectively adapt to the real network state. The larger the value of the network congestion index, the more serious the network congestion condition, and the network state can be defined as different congestion levels according to the range of the network congestion index.

In one embodiment, in step S202, the adjusting the preset initial exponent threshold according to the network monitoring data to obtain the current exponent threshold may include the following steps:

The method comprises the steps of determining packet loss rates, bandwidth utilization rates and time delay jitter of a plurality of member interfaces in monitoring time according to network monitoring data of the member interfaces, inputting preset initial index threshold values, packet loss rates, bandwidth utilization rates and time delay jitter into an adaptive filter, and adjusting the initial index threshold values by the adaptive filter according to the packet loss rates, the bandwidth utilization rates and the time delay jitter to obtain current index threshold values.

In a specific implementation, the packet loss rate, the bandwidth utilization rate and the delay jitter of the plurality of member interfaces in the monitoring time can be determined according to the network monitoring data of the plurality of member interfaces. The specific determination manner may refer to the foregoing embodiments, and will not be described herein.

After obtaining the packet loss rate, the bandwidth utilization rate, and the delay jitter, as shown in fig. 3, a preset initial exponent threshold (also referred to as an initial threshold) may be obtained, where the initial exponent threshold may include k_min and k_max. Then, the initial index threshold, the packet loss rate, the bandwidth utilization rate and the delay jitter can be input into the adaptive filter, and the adaptive filter dynamically adjusts the initial index threshold according to the packet loss rate, the bandwidth utilization rate and the delay jitter, for example, the threshold K_min and the threshold K_max are dynamically adjusted, so that the updated current index threshold can be obtained according to the output of the adaptive filter.

In this embodiment, by adjusting the initial exponential threshold by using an adaptive filter, the threshold can be dynamically adjusted by using an adaptive adjustment mechanism according to actual network data, so as to effectively reduce the occurrence of such erroneous judgment and missed judgment, thereby improving the stability of the system and the reliability of ARP message policy adjustment, for example, in the normal network fluctuation range, the threshold can be correspondingly adjusted to avoid triggering unnecessary alarms or operations due to small-amplitude fluctuation, and when a real problem occurs, the threshold can be timely adjusted to accurately identify the problem.

In an exemplary embodiment, in step S204, sending, through the plurality of member interfaces, an address resolution protocol packet to the plurality of packet receiving devices at a preset time interval for a plurality of times may include the steps of:

When the congestion state is the second level congestion, the processing priority of the address resolution protocol message is increased, and the address resolution protocol message is sent to the plurality of message receiving devices for a plurality of times according to the preset time interval, wherein the second level congestion is higher than the first level congestion.

In practical applications, the current exponent threshold may include k_min and k_max, and by combining the network congestion exponents of the logical interfaces with k_min and k_max, it may be determined whether the network is in a normal state or in a congested state, and a specific level of the congested state. For example, as shown in fig. 4, if the network congestion index C is in the range of 0+.c < k_min, the network state may be determined to be normal, where the network state is good, and no obvious congestion exists, if the network congestion index C is in the range of k_min+.c < k_max, the network may be determined to be in the first level of congestion, i.e. slightly congested, where slight congestion starts to occur, and some delay increase or packet loss may occur, and if the network congestion index C is in the range of c+.k_max, the network may be determined to be in the second level of congestion, where the network is in the serious congestion state, the user experience may be significantly affected, and the data transmission rate may be greatly reduced. It will be appreciated that as shown in fig. 4, the normal state, the first level congestion and the second level congestion may be switched between each other.

In this embodiment, when the congestion state is the first level congestion, the address resolution protocol packet may be sent to the plurality of packet receiving devices for multiple times according to the preset time interval, that is, the ARP packet may be sent for multiple times at regular time by adjusting the number of times of sending the ARP packet, so as to reduce the risk that the ARP packet may be delayed or lost. For example, a timing task may be configured in a network device or system that triggers the sending of ARP messages periodically.

When the congestion state is second-level congestion, the processing priority of the ARP message can be firstly increased, for example, the service quality (Quality of Service, qoS) configuration of the network equipment can be adjusted, the processing priority of the ARP message in the network traffic is ensured to be improved, thereby reducing delay and packet loss risks, ensuring timely transmission of the ARP message, and then the address resolution protocol message is sent to a plurality of message receiving equipment according to the adjusted processing priority for a plurality of times at preset time intervals, wherein the second-level congestion is higher than the first-level congestion. Thus, the ARP table entry can be ensured to be continuously updated, and even under the condition of high network load, the accurate address mapping among network devices can be maintained.

In this embodiment, when the congestion state is the first-level congestion, the address resolution problem possibly caused by congestion is relieved by sending ARP messages for multiple times, and the possible failure of address resolution under light congestion can be solved at a lower cost without requiring complex processing logic and additional resource investment; when the congestion state is the second level congestion, the ARP message is still subjected to successful processing by priority processing and repeated sending, so that the network communication problem caused by untimely ARP message processing under the condition of network congestion is solved, normal communication among devices in a network is maintained, and the capability of the system for coping with heavy congestion is enhanced. In addition, the embodiment concentrates, when the network is normal, the normal forwarding of the ARP message is maintained, when the network is slightly congested, the ARP message is sent regularly to prevent the ARP list item from being lost, when the network is severely congested, the priority of the ARP message is improved, the timely transmission of the ARP message is ensured, the adaptive ARP message scheduling strategy can be differentiated and flexibly adopted under different network states, and the processing efficiency of the ARP message is improved.

In an exemplary embodiment, the process priority of the address resolution protocol message is increased, which may include the following steps:

When the address analysis protocol message to be sent is obtained, the address analysis protocol message is added to the special message queue, so that the special message queue can send the address analysis protocol message through the special bandwidth.

In a specific implementation, a message dedicated queue may be created and a corresponding dedicated bandwidth may be allocated to the message dedicated queue.

In one embodiment, qoS policies may be configured using a flow control tool (e.g., tc commands for Linux) to implement priority handling of certain types of network traffic through layered queues and filters.

Specifically, a root queue (root) may be first constructed, and the root queue may serve as an entry point of traffic, and a data packet to be sent may be distributed to a sub-queue under the root queue. A corresponding main queue may be set under the per-queue and a total bandwidth (e.g., 1 Mbps) may be set for the main queue. There may be one or more sub-queues under the main queue, where one sub-queue is a message-specific queue, and a portion of the total bandwidth is allocated as a specific bandwidth to the message-specific queue. When the main queue acquires the data packet, the ARP message (namely the ARP data packet) can be added into the acquired message special queue according to the filtering rule, so that the message special queue can transmit the address resolution protocol message through the special bandwidth, and the message special queue can transmit the address resolution protocol message through the special bandwidth. In some embodiments, the dedicated bandwidth allocated to the message-specific queue may be greater than or equal to a predetermined proportion, thereby ensuring that the message-specific bandwidth has sufficient bandwidth to transmit ARP messages.

In this embodiment, by creating a dedicated queue for a message and allocating a dedicated bandwidth to the queue, an ARP message does not need to compete with other messages in a network congestion environment, so that the ARP message can be ensured to be processed in time even when the network is congested, and the ARP message can still be rapidly processed through the dedicated queue and the dedicated bandwidth, so as to maintain normal operation of the network.

In some embodiments, when it is determined that the network state is switched from the congestion state to the normal state, the ARP message priority may be restored, e.g., the filtering rule is deleted, so that the ARP message priority normally enters a corresponding queue (e.g., other than the message-specific queue).

In an exemplary embodiment, sending, through the plurality of member interfaces, the address resolution protocol packet to the plurality of packet receiving devices at a plurality of preset time intervals may include the steps of:

And executing the message sending script for a plurality of times according to a preset time interval to send an address resolution protocol message to the message receiving equipment through a plurality of member interfaces when the message sending script is executed.

In a specific implementation, a user may pre-write a message sending script, where the message sending script may instruct the server to send a gratuitous ARP message (e.g., 1 gratuitous ARP request) from a designated member interface to a message receiving device indicated by a target address.

Then, the message sending script may be executed multiple times at preset time intervals, so that when the message sending script is executed, the trigger server sends an address resolution protocol message to the message receiving device through multiple member interfaces. In an alternative embodiment, a timer file may be created, which may instruct to execute the messaging script every x seconds, thereby enabling the function of sending gratuitous ARP requests at regular intervals.

In the embodiment, on one hand, the message sending script is constructed in advance, so that the ARP message can be sent only by executing the script for multiple times according to the preset time interval, manual configuration and sending are not needed each time, the workload of manual operation is greatly reduced, the operation efficiency is improved, and on the other hand, the mode, the content, the sending time interval and the like of each time of sending the ARP message can be ensured to be consistent, and the stability and the reliability of network communication are ensured.

In one embodiment, when it is determined that the network state switches from the congestion state to the normal state, the timing of the ARP message may be stopped, for example, the timer may be stopped to trigger the execution of the messaging script.

In an exemplary embodiment, another address resolution protocol messaging method is provided, as described below in connection with fig. 5. In this example, the following steps may be included:

s501, determining a plurality of member interfaces aggregated through a bond port (namely a logic interface) of a server, and then, within a monitoring time T, acquiring traffic state monitoring data of the plurality of member interfaces in the bond port.

S502, calculating total message number and total packet loss number in the monitoring time T according to the flow state monitoring data of the plurality of member interfaces, calculating packet loss rate in the monitoring time T according to the total message number and the total packet loss number, calculating total received bytes in the monitoring time T according to the flow state monitoring data of the plurality of member interfaces, determining bandwidth utilization rate of the monitoring time T according to the total received bytes, determining RTT value of the monitoring time T according to the flow state monitoring data of the plurality of member interfaces, and determining delay jitter of the monitoring time T according to the RTT value.

S503, determining a congestion index (namely, a network congestion index) C according to the packet loss rate, the bandwidth utilization rate and the time delay jitter, inputting an initial threshold value, the packet loss rate, the bandwidth utilization rate and the time delay jitter into the adaptive filter, and determining dynamically adjusted threshold values K_min and K_max.

S504, if C is less than or equal to K_min, no extra measures are needed, if K_min is less than or equal to C is less than or equal to K_max, the member interfaces are triggered to send ARP messages to the message receiving devices at regular time, if C is more than or equal to K_max, the ARP message processing priority is increased, and the member interfaces are triggered to send ARP messages to the message receiving devices at regular time. Then, the process returns to step S501 again.
