Description

Method, device and storage medium for accelerating soft forwarding of VXLAN message
Technical Field
The present invention relates to the field of electronic communications, and in particular, to a method, an apparatus, and a storage medium for accelerating soft forwarding of VXLAN messages.
Background
VXLAN (Virtual eXtensible LocalAreaNetwork, virtual extended lan) adopts a MAC in UDP (User Datagram Protocol ) encapsulation, which is a network virtualization technology in NVO3 (NetworkVirtualization over Layer 3, cross-layer network virtualization). VXLAN is essentially a tunneling technique, in which a logical tunnel is established over an IP network between a source network device and a destination network device, and a user-side packet is forwarded through the tunnel after being specifically encapsulated.
For the problems of the large two-layer network, the VXLAN can encapsulate the data packet sent by the virtual machine in UDP, and uses the IP and MAC addresses of the physical network as outer layer headers to encapsulate, so that the network is represented as encapsulated parameters, and the requirement of the large two-layer network on the MAC address specification is reduced; VXLAN can introduce user identification VNI (VXLAN Network Identifier, VXLAN network identification) and support VXLAN segments up to 16M, so that a large number of user identifications are satisfied; the VXLAN can extend a two-layer network by adopting MAC in UDP encapsulation, and the Ethernet message is encapsulated on the IP message and transmitted in the network through a route without paying attention to the MAC address of the virtual machine, and the virtual machine migration is not limited by a network architecture through the route network, so that the VXLAN has large-scale expansion capability, fault self-healing capability and load balancing capability.
In a soft forwarding scene in the prior art, for decapsulation, a CPU analyzes a message layer by layer to decapsulate to obtain an original message, and the soft forwarding efficiency of the message is affected; for encapsulation, the speed of processing the message to be forwarded by the CPU layer by layer is slower, and the soft forwarding efficiency of the message is affected.

Detailed Description
The following detailed description of embodiments of the invention is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.
The following describes in detail the technical solutions provided by the embodiments of the present invention with reference to the accompanying drawings.
Related art knowledge and related terms related to embodiments of the present application will be first described with reference to fig. 1 to 3.
Tunneling is a way to transfer data between networks using the infrastructure of the internetwork, an end-to-end protocol that repacks original data packets and sends them to the opposite end through a tunnel, where the data transferred using the tunnel may be data frames or packets of different protocols. The tunnel can repackage and send data frames or packets of other protocols through the tunnel, wherein the data frame header can provide routing information to communicate the encapsulated payload data over the internet.
As shown in fig. 1, the format of VXLAN messages is shown. The VXLAN message needs to add an encapsulation header to the original message, where the encapsulation header includes a VXLAN header, a UDP header, a three-layer header, and a two-layer header, that is, a VXLAN header, and a transport layer, a data link layer, and a network layer header. The UDP header comprises a destination UDP port number and source UDP port number information, the three-layer header comprises a destination IP address and source IP address information, and the two-layer header comprises a destination MAC address and source MAC address information.
The VXLAN gateway comprises a two-layer gateway and a three-layer gateway, wherein the two-layer gateway is used for solving the problem that tenants access the VXLAN virtual network and can also be used for subnet communication of the same VXLAN virtual network; the three-layer gateway is used for cross-subnet communication of the VXLAN virtual network and access of external networks.
In the prior art, a switch chip includes a software part and a hardware part, which may be a CPU part and an ASIC chip part in this embodiment, and in a soft forwarding scenario, a three-layer forwarding service is generally assumed by the CPU. For VXLAN messages received by a tunnel end point, the CPU strips the package of the outer layer of the message, and processes the original inner layer message; for the message needing to enter the tunnel, the CPU adds encapsulation for the message.
As shown in fig. 2, when the CPU receives the tunnel termination message, first, performing outer layer two-layer processing, and judging whether the message needs to go through three layers of messages according to whether the destination MAC address is the native MAC address; sending the message to an outer layer three-layer processing, and judging whether the message is to be terminated locally or not according to whether the target IP is the local IP address or not; then, the processed data is sent to an outer four-layer process, and the processed data is sent to a VXLAN process according to the characteristic of the DestPort to the VXLAN; and according to the characteristics of IPDA, IPSA, VNI and the like, the VXLAN processing judges and matches the local tunnel, then the package of the message is stripped, and the message is sent to the two-layer processing to carry out multi-layer processing on the original message.
As shown in fig. 3, when the CPU receives a message to be forwarded, which needs to enter a tunnel, the CPU first determines the outer layer two and the outer layer three, sends the message to VXLAN for processing, and according to the characteristics of IPDA, IPSA, VNI, and the like, the VXLAN processes the message to determine and match the local tunnel, and then adds a package to the message.
As can be seen, VLAN termination refers to that the device identifies a VLAN tag in a received packet, strips the VLAN tag in the packet according to a subsequent forwarding behavior, and forwards or otherwise processes the packet. The VLAN tag is validated only before termination and subsequent forwarding or other processing is no longer dependent on the VLAN tag. The message received by the interface is forwarded after the VLAN label is stripped; and adding the corresponding VLAN label to the message sent by the interface and forwarding the message.
Example 1
As shown in fig. 4 to 5, a method for accelerating soft forwarding of VXLAN messages in an embodiment of the present invention is described, the method including the following steps.
In step S401, based on the configuration information of the VXLAN tunnel, the VXLAN packet added flow identifier is selected from the ASIC chip.
In this embodiment, a matching rule of VXLAN packet is preset, and when VXLAN tunnel is configured, information such as IPDA, IPSA, VNI is specified.
As shown in fig. 5, an ACL module is added to the ASIC chip in the chip entry direction, and ACL (Access Control List ) rules are set according to configuration information of different VXLAN tunnels. The ACL module is used for matching the characteristic message and adding carrying information, and can pre-store the table items for recording the matching information of different VXLAN tunnels.
Based on ACL rules, selecting VXLAN messages corresponding to different VXLAN tunnels and adding corresponding flow identifiers, wherein the information of the ACL rules comprises IPDA, IPSA and VNI information of the different VXLAN tunnels, and the IPDA, the IPSA and the VNI are used as keys of the ACL rules. The VNI may identify the VXLAN message, so no destination UDP port is required to be specified, etc.
The VNI is a VXLAN network identifier, which is used to distinguish VXLAN segments, and virtual machines of different VXLAN segments cannot directly communicate with each other in two layers. One VNI represents one tenant, even if a plurality of end users belong to the same VNI. VNIs consist of 24 bits, supporting tenants up to 16M.
Specifically, when the ASIC chip identifies a VXLAN message matching the corresponding ACL rule, a corresponding Flow ID is added to the VXLAN message, and the message to which the Flow ID is added is sent to the CPU. Wherein the flow identifier is used to mark VXLAN messages that terminate locally.
In step S402, the VXLAN packet carrying the flow id is sent to the VXLAN processing module for decapsulation.
Specifically, the CPU sends a message carrying the flow identifier to the VXLAN for decapsulation processing. Because the ASIC chip matches the message in advance, the CPU can directly strip the VXLAN header, the UDP header, the three-layer header and the two-layer header of the message package, so that the time waste caused by the layer-by-layer analysis of the message package header by the CPU is avoided.
In step S403, the decapsulated VXLAN message is sent to the inner layer processing and forwarded.
Specifically, after the message carrying the flow identifier is unpacked in the VXLAN, an original message is obtained, the original message is sent to an inner layer for processing, and the processed message is transferred to an ASIC chip for forwarding. The inner layer processing includes data link layer processing, network layer processing and UDP processing.
Example 2
As shown in fig. 6 to 7, a method for accelerating soft forwarding of VXLAN messages in an embodiment of the present invention is described, the method including the following steps.
In step S601, when VXLAN processing is performed, an edit identifier is added to a message to be encapsulated, where the edit identifier is used to mark the message to be encapsulated forwarded by the host and is carried by the message to be encapsulated.
As shown in fig. 7, in the chip outgoing direction, based on the editing module in the ASIC chip, an editing table is set according to configuration information of different VXLAN tunnels, and the editing table is stored in the ASIC chip in advance. The editing module is mainly used for carrying out encapsulation editing on the message which needs to be forwarded by the local machine.
Specifically, when VXLAN processing is performed, corresponding editing identifiers are added to messages to be encapsulated corresponding to different VXLAN tunnels.
In step S602, based on the configuration information of the VXLAN tunnel, the message to be encapsulated carrying the edit identifier is encapsulated and forwarded in the ASIC chip.
Specifically, based on the corresponding information in the matched editing table, corresponding encapsulation operation is performed on the message to be encapsulated carrying the corresponding editing identifier in the ASIC chip, and the encapsulated message is forwarded. The information of the edit table comprises IPDA, IPDA and VNI information of different VXLAN tunnels.
Further, the encapsulating operation includes adding a corresponding VXLAN header, UDP header, network layer header, and data link layer header to the message carrying the edit identifier.
According to the method for accelerating the soft forwarding of the VXLAN message, disclosed by the embodiment of the invention, the flow identifier can be added for the identified terminal message through the ASIC chip, and the message is sent to the CPU to be directly unpacked, so that the unpacking speed of the VXLAN message is effectively improved; the CPU can add editing identification to the message, and send the message to the ASIC chip for encapsulation, so that the speed of the message encapsulation is effectively improved.
