A system and method for automatic identification of heterogeneous link multi-protocol

Abstract

The invention discloses a multi-protocol automatic identification system and method for a heterogeneous link. The system is carried on a system on chip device which takes a programmable chip as a hardware platform. A standard protocol data frame is generated by using the data frame parameters of different protocols input by a user, and different protocol identification identifier flow tables and flow table sub-data domain identification marks are added correspondingly, so that automatic identification of a plurality of protocols is finished without resolving specific content of the data frame. The system is provided with three components, namely, a standard protocol generating module for generating data frames, a protocol identification identifier adding module for adding a protocol identification identifier serving as an identification basis, and a multi-protocol automatic identification module for detecting a data frame protocol type. By adopting the multi-protocol automatic identification system and method, automatic identification of multi-protocol data frames under the heterogeneous link can be realized in a full-automatic way. In a communication system in which a plurality of common communication protocols coexist, a plurality of communication protocols are identified automatically, the accuracy is high, data frame loss and incorrect processing caused by wrong identification of protocols can be reduced, and the network flexibility and robustness are improved.

Description

technical field [0001] The invention relates to a system and method for automatically identifying protocols in a communication system where multiple protocols coexist under heterogeneous links. Its application scenario is an on-chip system with a programmable chip as a hardware platform, which belongs to the technology of communication protocol identification field. Background technique [0002] With the rapid development of communication technology and the continuous expansion of its application scope, the scale of communication system becomes larger and larger, and its application environment becomes more and more complex. Currently, in many cases, multiple different communication protocols may exist and be used in the same communication system. In such a communication system, different access devices follow different communication protocols to send and receive data, and the data generated by them in different communication protocols need to be processed accordingly.
