A method and device for implementing rfc2544 in vpws environment

Abstract

A method and device for implementing RFC2544 in a VPWS environment, including a multi-core CPU as the core of the control plane, running multiple control plane protocols, and generating various entries of VPWS and RFC2544 required when the forwarding plane processes data packets, and the multi-core CPU is also used to generate RFC2544 active end test data packet; the forwarding plane is implemented by the switch chip and FPGA, the switch chip and FPGA cooperate with each other to process the RFC2544 test data packet in the VPWS environment; for the RFC2544 active end packet, the multi-core CPU generates the test data packet and writes it to FPGA, FPGA Send the test traffic to the switch chip, and the switch chip sends the test traffic; for the RFC2544 passive end, after the switch chip receives and processes the packets, it sends the test traffic to the FPGA, and the FPGA sends the test traffic to the switch chip again, and the switch chip sends the test traffic The traffic is sent out; for the RFC2544 active end to receive packets, the switch chip will send the test traffic to the FPGA after receiving the packets, and the FPGA will perform the final calculation of the RFC2544 test parameters on the test traffic; it can realize the line-speed forwarding of the device port to ensure the integrity of the device port. Forwarding performance.

Description

technical field [0001] The invention relates to the technical field of computer network data communication, in particular to a method and equipment for realizing RFC2544 in a VPWS environment. Background technique [0002] VPWS (Virtual Private Wire Service), which refers to the infrastructure built on the MPLS network, provides high-speed Layer 2 transparent transmission between a pair of ports of two routers, and can transmit the original Ethernet packets of the local PE device Transparently transmitted to the remote PE device, it is a layer 2 VPN protocol. [0003] The RFC2544 protocol is an international standard proposed by the RFC organization for evaluating network interconnection devices (firewall, IDS, Switch, etc.). It mainly stipulates in detail the specific test methods and the submission form of the performance evaluation parameters defined in RFC1242. RFC2544 stipulates many parameters for testing different network devices, mainly including the four most impo...

Problems solved by technology

At present, mainstream switching chips in the industry, such as broadcom or Marvel, do not have the ability to generate RFC2544 test data streams. If CPU soft forwarding is used to generate test data streams, although the code is flexible, the forwarding capability is too poor, the port cannot be line-speed, and the CPU The delay error of the measured data stream is large
