Experimental platform and experimental method supporting protocol-independent packet processing

Abstract

The embodiment of the invention provides an experimental platform and experimental method supporting protocol-independent packet processing. The experimental platform supporting the protocol-independent packet processing comprises a control module, a compiler module, a sending module, a switch group, a receiving module, a data processing module and a GUI module. Through the experimental platform and experimental method supporting the protocol-independent packet processing provided by the embodiment of the invention, when a user needs to perform a simulation experiment, the configuration instruction information written in advance and the switch processing logic information can be input into the experimental platform, so that the simulation experiment can be performed easily, therefore, therepeating and cumbersome process of configuring the experimental environment is avoided, and the need for the simulation of the processing logic written in the P4 language can be met; further, the experimental platform supporting the protocol-independent packet processing can also be used for the performance experiment of the switches supporting the protocol-independent packet processing.

Description

technical field [0001] The invention relates to the technical field of software-defined networks, in particular to an experimental platform and an experimental method supporting protocol-independent data packet processing. Background technique [0002] With the emergence of emerging services such as cloud computing, virtualization, and big data, and the continuous expansion of network scale, people have more and more requirements for the types of protocols and types of devices supported in the network. However, in the existing SDN (Software Defined Network, software-defined network) architecture based on the OpenFlow protocol, the protocol in the forwarding device is solidified in the forwarding device by the manufacturer during production, making it difficult to change the protocol in the forwarding device. [0003] In order to solve this problem, people have proposed data plane programmable technology, which is represented by P4 (Programming Protocol-independent Packet Pro...

Problems solved by technology

[0005] However, since the P4 language is still in the early stages of development, in order to enable learners of the P4 language to understand the P4 language more intuitively and clearly, it is necessary to simulate the processing logic written in the P4 language during the learning process. There is no experimental environment for simulating the processing logic written in P4 language
