Abstract

The invention discloses an ICMP request message keep-alive control method and system. The method comprises the steps of when the application program in a server works normally, receiving a startup instruction sent from the application program by invoking a keep-alive interface; according to the startup instruction, switching on a kernel timer to start timing; when the timing of the kernel timer exceeds a preset time and the keep-alive interface is not invoked by the application program during the timing period, judging that the application breaks down so as to be incapable of normally responding to the data service shunt from a shunt, and stopping replying to an ICMP request message. In this way, when the shunt cannot receive any ICMP protocol-based response message from the server, the shunt does not transmit the data traffic to the server. Therefore, the problem in the prior art that when the application program arranged in the server and used for providing services breaks down, one part of the services cannot respond to the request is solved.

Description

technical field [0001] The invention relates to the technical field of ICMP communication, in particular to an ICMP request message keep-alive control method and system. Background technique [0002] At present, with the rapid development of computer technology and information network technology, the Internet is getting closer and closer to people's daily life, and it brings more and more convenience to people's work and life. [0003] While the Internet brings many conveniences, the amount of data on the Internet is growing in a blowout manner. In some specific-purpose applications, such as servers that provide data access services, data filtering and other services, distributed cluster servers are required to To handle large concurrent data, diversion devices are usually used to divert the traffic to different servers in the cluster server, so that both load balancing and traffic classification can be achieved. However, during the above-mentioned distribution process, whe...
