Description

A traffic statistics method, device and computer-readable storage medium

technical field

The present invention relates to the field of wireless communication technologies, and in particular, to a traffic statistics method, an apparatus and a computer-readable storage medium.

Background technique

Cloud computing has become the focus of the construction of current IT giants. The importance of virtualized data centers as an important part of cloud computing is evident. From the perspective of computing resources such as hosts, data center virtualization includes multiple virtual ones and one virtual multiples Both directions provide a means for computing resources to be allocated on demand. The main purpose of system virtualization is to shorten the time of business deployment and improve the efficiency of resource use. It hides the process of the underlying physical hardware in some way, so that multiple operating systems can transparently use and share it, mainly on one physical system. The technology that multiple operating systems coexist at the same time.

Edge virtual bridge (Edge Virtual Bridging, EVB) technology is currently used to solve the problem of connection and management boundary between a virtual machine (Virtual Machine, VM) and a network in a virtualized environment. And on the basis of the framework defined by this standard 802.1Qbg, the automatic association between the VM life cycle and the network, and the flexible change of network attributes can be realized.

EVB was originally composed of 802.1Qbg and 802.1Qbh. There are four implementations of the data plane: 802.1Qbg includes three, namely Virtual Ethernet Bridging (VEB) mode, Virtual Ethernet Port Aggregator (Virtual Ethernet Port Aggregator, VEPA) mode and multi-channel Multi Channel mode; 802.1Qbh is a port extension (Port Extender, PE) mode. Currently, 802.1Qbh has been cancelled in EVB, so EVB is currently 802.1Qbg. From the perspective of technical implementation and in some special application scenarios, different modes of 802.1Qbg can exist at the same time, and it is technically required to be able to be cascaded in multiple layers, which is also described in the standard preparatory document. But in more scenarios, complex cascade topologies and layers are not required, and the standard recommends a basic EVB architecture for use.

Virtualized data centers bring some challenges to the network side. As shown in Figure 1, VMs are the same as ordinary EVB server devices. Each VM has its own virtual NIC (virtual NIC), and each virtual NIC has its own media access control. (medium access control, MAC) address and IP address. A virtual switch (Virtual Switch), that is, a vSwitch is equivalent to a virtual Layer 2 switch. ABCDE are virtual ports on the vSwitch. The vSwitch connects the virtual NIC and the physical NIC, and forwards data packets on the VM from the physical network port. As required, vSwitch can also support Layer 2 forwarding, security control, port mirroring and other functions. In this solution, the network administrator cannot see the vSwitch, which causes the vSwitch to be separated from the overall network management, which is not conducive to the realization of overall network security monitoring.

In order to separate the EVB server from the complex network switching work, return to the original service application function, and return the message forwarding and network policy control to the network device to complete, consider another method to realize the VM network communication, That's what the IEEE 802.1Qbg standard is about, specifying an EVB standard based on VEPA technology. Through the VEPA technology, all traffic from the VM is forwarded to the adjacent physical access switch, so that the network access switch can see the VM's packet flow. In this case, when the target VM is also located on the same EVB server, it is transferred back to the same physical EVB server, and the traffic is turned 180 degrees. As shown in Figure 2, between VMs within the same host EVB server Station All traffic needs to go through network devices for snake forwarding. In this way, the network device can know the traffic information between the VMs inside the Station.

The existing VEPA technology enables network administrators to monitor the network traffic between VMs in the same Station and control the traffic information of the entire data center network, but the consequence is that the packets that could have been directly forwarded inside the VM are transferred. It is necessary to make a 180-degree serpentine forwarding to the same port of the network device, which is a great waste of the bandwidth resources of the network device, and also brings unnecessary bandwidth delay.

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Example 1

An embodiment of the present invention provides a traffic statistics method, which is applied to an EVB server. As shown in FIG. 3 , the method includes:

S301, by performing statistics on the transmission data of the VM through a virtual switch to obtain the traffic parameters of the VM;

When forwarding the transmission data, determine whether the source address and destination address of the transmission data belong to the same EVB server; when it is determined that the source address and destination address of the transmission data belong to the same EVB server, transmit the transmission through the first path data, the first path is the internal path of the EVB server; when it is determined that the source address and destination address of the transmission data do not belong to the same EVB server, the transmission data is transmitted through the second path, and the second path is The path between the EVB server and the EVB switch. Wherein, the source VM that sends out data can be used as the source address, and the target VM that receives the data can be used as the target address.

The EVB server includes a VM and a virtual switch, and the transmission data of the VM is exchanged and controlled through the virtual switch to realize the forwarding of the transmission data of the VM. Wherein, one EVB server may include one or more VMs. According to whether the EVB server to which the source VM that sends the data and the target VM that receives the data belong are the same EVB server, the transmission data is divided into two types of data: internal transmission data and external transmission data, and the transmission path of the internal transmission data is the first path , the transmission path of the external transmission data is the second path.

The source and destination VMs that transfer data internally belong to the same EVB server. When the data is internal transmission data, the transmission data sent by the source VM is sent to the source virtual switch corresponding to the source VM. After identifying the target address, the source virtual switch forwards the data to the target virtual switch, and the target virtual switch forwards the transmission data. To the target VM, the internal forwarding of the EVB server is realized. Here, the source virtual switch and the target virtual switch may be the same virtual switch, or may be different virtual switches in the same EVB server. Here, the first path for transmitting data is the internal path of the EVB server.

The source VM and the target VM for externally transferring data belong to different EVB servers. When the data is external transmission data, for different transmission data, the EVB server can be used as both the source EVB server that sends the data and the target EVB server that receives the data.

When forwarding the transmission data, the transmission data of the source VM in the source EVB server is sent to the source virtual switch corresponding to the source VM. After identifying the target address, the source virtual switch forwards the transmission data to the source corresponding to the source EVB server. The EVB switch, the source EVB switch forwards the transmission data to the target EVB switch corresponding to the target EVB server, and the target EVB switch forwards the transmission data to the target VM in the target EVB server. Here, the source EVB switch and the target EVB switch may be the same EVB switch, or may be different EVB switches. Here, the second path for data transmission is the path between the EVB server and the EVB switch.

Here, when transmitting data, the virtual switch corresponding to the VM can collect statistics on the transmitted data to obtain the traffic parameters of the transmitted data, where the traffic parameters can include: the maximum rate of incoming interface packets, and the maximum rate of outgoing interface packets. rate, the total number of received packets, the total number of sent packets, the number of unicast packets received by the interface, the number of unicast packets sent by the interface, the number of multicast packets received by the interface, and the number of multicast packets sent by the interface. number, the number of broadcast packets received by the interface, the number of broadcast packets sent by the interface, the number of jumbo frame length packets received by the interface, the number of jumbo frame length packets sent by the interface, and the discarded packets detected by the interface during physical layer detection. Parameters related to traffic statistics, such as the number of packets, the total number of error packets detected by the interface during physical layer detection, and the number of CRC error packets received by the interface.

In practical applications, the traffic statistics parameters may be a combination of one or more of the above parameters, and the traffic statistics parameters may also be set according to actual requirements.

S302. Generate a traffic state notification according to the traffic parameter and the communication identifier of the VM, and send the traffic state notification to the EVB switch.

After statistics on the traffic parameters of the VM are obtained, the traffic parameters are sent to the EVB switch through the traffic status notification. When generating the traffic status notification, the traffic parameters of the VM and the communication identifier of the VM are encapsulated in the traffic status notification at the same time, and the communication identifier of the VM may be the MAC address of the VM.

In some embodiments, the traffic status notification is generated by setting a traffic statistics flag in the status notification based on a channel discovery and configuration protocol (CDCP). Specifically, the reserved field of the status notification can be set as a custom traffic statistic identifier, so as to generate a traffic status notification to indicate that the status notification carries the traffic parameters to distinguish it from the status notification that does not carry the traffic parameters. The traffic statistic identifier can be Set according to user needs, for example: the reserved field is 0x1.

When generating the traffic status notification, a traffic statistics information field may be added on the basis of the status notification with the traffic statistics identifier, and the traffic parameters and the communication identifier of the VM are encapsulated in the traffic statistics information field. For example, a traffic statistics field is added to the service channel identifier (S-channel ID, SCID)/service VLAN identifier (S-VLAN ID, SVID) pair of the status notification.

In some embodiments, before sending the traffic status notification to the EVB switch, a virtual service provider channel corresponding to the virtual switch is determined; and a channel identifier of the virtual service provider channel is added to the traffic status notification to pass the virtual The service provider channel corresponding to the switch sends the traffic status notification.

When the EVB server includes multiple virtual switches, multiple virtual service provider channels exist between the multiple virtual switches and the EVB switch, and the multiple virtual service provider channels are implemented through one physical channel between the EVB server and the EVB switch. At this time, the virtual switch that sends the traffic status notification sends a request message to the EVB switch to request the creation of a virtual service provider channel; the EVB switch allocates a virtual service provider channel and creates a virtual service provider channel according to the virtual switch corresponding to the request message. The server returns a virtual service provider channel creation notification. When the EVB server receives the virtual service provider channel creation notification returned by the EVB switch, it sends a traffic status notification to the EVB switch through the created service provider channel. Before sending the traffic state notification, the EVB server adds the channel identifier of the virtual service provider channel to the traffic state notification, so as to identify the virtual service provider channel to which the traffic state notification belongs. Here, the form of the channel identification can be set according to actual needs.

When the virtual switch starts to transmit data, the EVB server creates a virtual service provider channel for the virtual switch. In the process of data transmission, it can periodically send traffic status notifications to the EVB switch. The traffic parameters carried in the issued traffic status notifications are the traffic parameters counted at the time of sending. After the data transmission is completed, a request is sent to the EVB switch. message to delete the virtual service provider channel corresponding to the virtual switch.

It should be noted that the EVB server can simultaneously send traffic status notifications of multiple virtual switches to the EVB switch through different virtual service provider channels.

When the EVB switch receives the traffic status notification, it parses the traffic status notification to obtain the traffic parameters sent by the EVB server and the VM to which the traffic parameters belong.

In the embodiment of the present invention, the EVB server collects statistics on the transmission data of the VM through the virtual switch to obtain the traffic parameters of the VM, generates a traffic status notification according to the traffic parameters and the communication identifier of the VM, and sends the traffic status notification to EVB switch: It can realize the statistics and monitoring of the network traffic of the internal VM of the EVB server by the EVB switch through the sending of traffic parameters, and the EVB server conducts traffic statistics to avoid snake-like forwarding.

Further, when transmitting the transmission data, the transmission data whose source address and destination address belong to the same EVB server are transmitted in the EVB server, and the transmission data whose source address and destination address do not belong to the same EVB server are transmitted through the EVB switch. , thereby reducing the waste of broadband resources and reducing the transmission delay.

Embodiment 2

An embodiment of the present invention provides a traffic statistics method, which is applied to an EVB switch, as shown in FIG. 4 , including:

S401. Receive a traffic status notification sent by an EVB server, and parse the traffic status notification to obtain a traffic parameter and a communication identifier of the VM;

The traffic parameter is obtained by collecting statistics on the transmission data of the VM by the virtual switch of the EVB server.

When the VM in the EVB server transmits the transmission data, the EVB server collects statistics on the transmission data of the VM through the virtual switch corresponding to the VM that transmits the data, wherein the transmission data includes the transmission data of the first path and the transmission of the second path For data, the first path is the internal path of the EVB server, and the second path is the path between the EVB server and the EVB switch. After the virtual switch collects statistics on the transmission data of the VM to obtain the traffic parameters corresponding to the VM, it encapsulates the traffic parameters and the communication identifier of the VM to generate a traffic state identifier, and sends the generated traffic state identifier to the EVB switch.

The EVB switch receives the traffic status notification, parses the traffic status notification, and parses out the traffic parameters carried in the traffic status notification and the communication identifier of the VM, where the traffic parameters may include: the maximum rate of incoming interface packets, the Maximum rate, total number of received packets, total number of sent packets, number of unicast packets received by the interface, number of unicast packets sent by the interface, number of multicast packets received by the interface, multicast packets sent by the interface The number of broadcast packets received by the interface, the number of broadcast packets sent by the interface, the number of jumbo frame length packets received by the interface, the number of jumbo frame length packets sent by the interface, and the discards found by the interface during physical layer detection. Parameters related to traffic statistics, such as the number of packets, the total number of error packets detected by the interface during physical layer detection, and the number of CRC error packets received by the interface. The communication identifier of the VM may be the MAC address of the VM.

In some embodiments, the traffic status notification is a status notification added with a traffic statistics identifier. When the EVB switch receives the status notification, it parses the status notification based on CDCP, detects that the analysis result includes a traffic statistics identifier, and determines that the status notification is a traffic status notification. When it is determined that the state notification is a traffic state notification, it is determined that the received state notification carries a traffic parameter, and the field corresponding to the traffic parameter is parsed to obtain the traffic parameter. Here, when the reserved field of the status notification is set to a custom traffic statistics identifier, it is determined that the status notification is a traffic status notification, so as to indicate that the status notification carries traffic parameters, so as to distinguish it from the status notifications that do not carry traffic parameters. The identifier can be set according to user needs, for example: the reserved field is 0x1.

When parsing the status notification based on CDCP, the traffic parameters and the communication identifier of the VM can be determined by identifying the newly added traffic statistics field in the status notification, for example: the traffic statistics field added in the SCID/SVID pair of the status notification .

In some embodiments, before the traffic status notification is parsed to obtain the traffic parameters and the communication identifier of the VM, the traffic status notification is parsed to obtain the channel identifier of the virtual service provider channel; The channel identifier determines the virtual switch to which the traffic parameter belongs. Here, there are multiple virtual service provider channels between the EVB switch and multiple virtual switches of the EVB server, and the multiple virtual service provider channels are implemented through a physical channel between the EVB switch and the EVB server. When the EVB switch receives a request message from the EVB server to request the creation of a virtual service provider channel, it allocates a virtual service provider channel to the virtual switch that sends the request according to the configuration of the virtual service provider channel, and creates a virtual service provider channel for the virtual switch. After the virtual service provider channel, the virtual service provider channel creation notification is returned to the EVB server, and the traffic status notification of the virtual switch sent by the EVB server is received through the created virtual service provider channel. Before sending the status traffic notification, the EVB server adds the channel ID of the virtual service provider channel to the traffic status notification. When the EVB switch receives the traffic status notification, it strips the channel ID of the virtual service provider channel carried in the traffic status notification and identifies the The channel identifier is used to determine the virtual service provider channel for transmitting the traffic status notification, and further determine the virtual switch to which the traffic parameters carried in the traffic status notification belong.

In the process of transmitting data, the EVB switch can periodically receive a traffic status notification of a virtual switch sent by the EVB server, and the traffic parameters carried in the received traffic status notification are the traffic parameters counted at the time of sending. When receiving a request message sent by the EVB server to delete the created virtual service provider channel, the virtual service provider channel can be deleted until the request message for creating a virtual service provider channel for the same virtual switch sent by the EVB server is received again to create a new virtual service provider channel The virtual service provider channel corresponding to the virtual switch.

It should be noted that when the EVB switch creates a virtual service provider channel, the created virtual service provider channel corresponds to the virtual switch, that is, there is a one-to-one correspondence between the virtual service provider channel and the virtual switch. Virtual service provider channels corresponding to multiple virtual switches can be created simultaneously between the EVB switch and the EVB server, so as to receive traffic status notifications from different virtual switches, and to obtain the traffic parameters of the internal data transmission of the EVB server.

S402, using the traffic parameter to perform traffic statistics on the VM;

After the EVB switch obtains the traffic parameters of the VM, it uses the traffic parameters to collect statistics on the traffic of the VM. In practical applications, the EVB switch performs traffic statistics on the VM through the traffic parameters carried in multiple traffic status notifications of the same VM sent by the switch.

The statistics of the traffic of the server can be realized by the statistics of the traffic of each VM in the same EVB server.

After the EVB switch determines the traffic of the VM of the EVB server, it can report the statistics traffic to the network management system for the network management personnel to check.

In the embodiment of the present invention, the EVB switch collects statistics on the traffic of the VMs in the EVB through the traffic status notification received from the EVB, and the EVB does not need to perform traffic statistics based on the forwarded data, which avoids the need for the data forwarded by the server to pass through the snake. forwarding, which reduces the waste of broadband resources and reduces the transmission delay.

Embodiment 3

An embodiment of the present invention provides a traffic statistics method, which is applied to a network system including an EVB server and an EVB switch, as shown in FIG. 5 , including:

S501, the EVB server collects statistics on the transmission data of the VM through the virtual switch to obtain the traffic parameters of the VM, generates a traffic status notification according to the traffic parameters and the communication identifier of the VM, and sends the traffic status notification to the EVB switch;

S502. The EVB switch receives the traffic status notification sent by the EVB server, parses the traffic status notification to obtain the traffic parameter and the communication identifier of the VM, and uses the traffic parameter to perform traffic statistics on the VM .

In some embodiments, the EVB server determines whether the source address and the destination address of the transmission data belong to the same EVB server; when it is determined that the source address and the destination address of the transmission data belong to the same EVB server, the transmission is transmitted through the first path data, the first path is the internal path of the EVB server; when it is determined that the source address and destination address of the transmission data do not belong to the same EVB server, the transmission data is transmitted through the second path, and the second path is The path between the EVB server and the EVB switch.

In some embodiments, before sending the traffic status notification to the EVB switch, the EVB server determines a virtual service provider channel corresponding to the virtual switch; and adds a channel identifier of the virtual service provider channel to the traffic status notification.

At this time, the EVB switch parses the traffic state notification to obtain the channel identifier of the virtual service provider channel before obtaining the traffic parameters and the communication identifier of the VM by parsing the traffic state notification; according to the channel of the virtual service provider channel Identify the virtual switch to which the traffic parameter belongs.

In some embodiments, the EVB server generates the traffic status notification based on the CDCP setting the traffic statistics flag in the status notification. At this time, the EVB switch parses the received status notification based on CDCP, detects that the analysis result includes a traffic statistics identifier, and determines that the status notification is a traffic status notification.

Embodiment 4

The traffic statistics method provided by the embodiment of the present invention is described in detail below with reference to specific application embodiments.

The system structure composed of EVB server (station) and EVB switch (bridge) is shown in Figure 6. Station includes VM, vSwitch and service provider component (S-component), bridge includes S-component, and virtual channel between station and bridge It is called the virtual service provider channel S-channel.

CDCP is a link layer discovery protocol (LLDP)-based protocol for configuring the S-VLAN (service provider VLAN) of the S-channel. It is sent by encapsulating the device's own information in the TLV format in the message. Used to discover Layer 2 directly connected devices.

CDCP is a channel specially used to establish the connection between S-Component and the network in Multi Channel mode. The VEB/VEPA of the virtual switch on the EVB server is connected through the S-channel and the EVB switch. The S-channel is a virtual connection, which uses The S-VLAN components at both ends are connected.

The endpoints at both ends of the S-channel are called service provider channel endpoints (S-channel Access Port, CAP). The CAP is responsible for encapsulating the channel identifier S-tag when the packet enters the S-channel, and stripping the S-tag when the packet leaves the S-channel. tag. Since all virtual connections are transmitted on the same physical link, the purpose of this S-tag is to identify the channel corresponding to each virtual switch. That is, a vSwitch corresponds to an S-channel. The S-VLAN component can identify, insert, and remove S-tags enabling the operation of multiple S-channels on EVB switches.

As shown in Figure 7, the S-Channel configuration is determined by the EVB switch and saved on the EVB switch. The EVB server initiates an S-Channel resource request to the EVB switch, and the EVB switch allocates the S-VLAN. After the EVB switch function is enabled on the Ethernet interface of the Station, the EVB switch advertises status notification 701 through LLDP packets. When the VM has a request to create an S-Channel, or the original request changes, the channel request message 702 sends a request message for creating an S-Channel to the EVB switch. The EVB switch assigns an SVID to it to create a corresponding S-Channel interface, and then replies with a response packet 703 to notify the EVB server to assign the SVID of the S-Channel. The EVB server and the EVB switch carry the channel identifier of the current S-Channel in the subsequent packets to send the traffic status notification 704 . Here, traffic status advertisements 704 may be sent periodically. The EVB switch may also periodically send status notifications 701 to the EVB server. The EVB server periodically sends the CDCP traffic status notification to the EVB switch, carrying the traffic parameters and the VM's communication identifier. The switch parses the traffic status notification to know the traffic information corresponding to each VM.
