Abstract

The embodiment of the present invention discloses a method for realizing the self-adaptation of the link layer protocol of the POS port, including: detecting whether the link layer protocol type of the message received from the input port is consistent with the link layer protocol type configured on the input port , when the link layer protocol type of the message is inconsistent with the link layer protocol type configured on the input port, switch the link layer protocol type configured on the input port and the output port to be consistent with the link layer protocol type of the message The link layer protocol type. Through the solution of the embodiment of the present invention, the service processing interruption phenomenon caused by the different port link layer protocol configurations of the network equipment is avoided, and the maintenance investment of the operator and the safety supervision department is reduced, thereby improving the operation and maintenance of the entire network. In addition, the maintainability of the network equipment is improved, which is conducive to widely applying the network equipment to process security services.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and equipment for realizing the self-adaptation of the link layer protocol of a POS (Packet Over SONET / SDH, Synchronous Optical Network, Synchronous Optical Network; Synchronous Digital Hierarchy, Synchronous Digital Series) port. Background technique [0002] As network technology is more and more widely used in all aspects of national life, Internet security has exposed more problems, such as the indiscriminate dissemination of illegal information on the Internet, flooding of spam, virus Trojan horse hacking, and increasing financial crimes. Both information security and national information security are under great threat, and it is necessary to take effective measures to eliminate security risks. [0003] In order to effectively eliminate hidden dangers in the network and realize user needs such as green Internet access, virus detection, and attack prevention, ...
