Problems solved by technology

[0005] The inventor found that there are at least the following problems in the prior art: after deleting the abnormal group member, when the abnormal process group member resumes communication, there is no mechanism to notify that the abnormal group member has been deleted from the process group and needs to rejoin the process group , so it can only send messages to the process group, but cannot receive messages from members of the process group

Embodiment Construction

[0022] In order to better understand the present invention and make the present invention easy to implement. The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] An embodiment of the present invention provides a method for an abnormal group member in a process group to leave. Such as figure 1 As shown, the method includes the following steps:

[0024] S10: The sending group member performs anomaly detection on the group members in the process group to which it belongs, and determines the abnormal group member therefrom;

[0025] A process group is composed of multiple processes, and each process in the process group is a group member of this process group. Among them, the process sending messages in the process group is the sending group member in the process group, and the process receiving messages in the process group That is, the receiving group member in the process group, when a group ...

Abstract

This embodiment of the invention relates to a kind of process group and method for eliminating abnormal group member process group, involving the internet group management protocol and is aimming for solving the problem that there is no mechanism to inform when an abnormal group member of internet group management protocol is deleted. The techniques of this invention includes: the member of sending group develops anomaly detection of group members in an own process group and finds the abnormal group member; the member of sending group deletes the abnormal group member from all local group members; the member of sending group sends information to the abnormal group member to force the member to leave after the communicating data is recovered; the abnormal group member leaves the process group after receiving the force-leaving information. This invention is used in the communication of internet group management protocol.

Description

technical field [0001] The invention relates to an Internet group management protocol in the network, in particular to a process group and a method for leaving an abnormal group member in the process group. Background technique [0002] Multicast refers to the realization of point-to-multipoint network connection transmission between the sender and each receiver. The Internet Group Management Protocol (Internet Group Management Protocol, IGMP) is a multicast protocol in the Internet protocol family, used for hosts to report their group membership to any directly adjacent router. There is a large amount of inter-process communication in cluster routers, distributed routers. If a piece of data is concerned by multiple processes, let the relevant processes join a process group, and use multicast communication to communicate in order to save operating system resources such as connections and bandwidth. [0003] The communication between process group members often has high req...
