AI Technical Summary

Problems solved by technology

However, this not only increases the cost of the equipment and the complexity of the implementation of processing; but even if the method of high-performance CPU and multi-CPU processing load sharing is adopted, it is difficult to fundamentally solve the problem of hardware forwarding plane in the case of a large number of abnormal packets. The normal user logout problem caused by the congestion of the CPU software message channel

Embodiment Construction

[0050] The core of the present invention is that a large amount of normal link maintenance information in the equipment link maintenance work is directly handed over to the bottom layer hardware of the device for identification, processing and termination, and the link maintenance information is set in the shared memory table agreed with the CPU, and the bottom layer of the device The hardware maintains the table, and the CPU queries the shared memory table to maintain the device link and ensure the stability of normal online users. Its principle is shown in Figure 2.

[0051] Those skilled in the art know that the format of the PPP link maintenance information message is fixed, simple, and easy to identify and process. A summary of the Link Control Protocol packet format is as follows:

[0052] 0 1 2 3

[0053] 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1

Abstract

The present invention discloses a maintenance method of equipment chain link and its system. The described method includes the following steps: creating user chain link maintenance information list; sending down-chain link maintenance request message to customer end and receiving up-chain link maintenance information sent by customer end; according to received up-chain link maintenance information the described equipment can update user chain link maintenance information list; and according to user chain link maintenance information list the CPU in the equipment interior can be used for maintaining equipment chain link.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method and system for maintaining equipment links. Background technique [0002] With the rapid development of INTERNET, broadband Internet users have increased dramatically. In the process of large-scale construction of broadband networks by operators, the networking mode has undergone a transformation from ATM DSLAM (digital subscriber line access multiplexer with ATM core) to IP DSLAM (digital subscriber line access multiplexer with IP core). ), the transition from small-capacity BAS (broadband access server) to large-capacity BAS; as the number of Internet users continues to increase, online hacker attacks are becoming more and more intense. At the same time, the prevalence of network viruses has caused a large amount of abnormal traffic in the network , causing hidden dangers to the performance and equipment security of large-capacity BAS. At present, broad...
