Method and system for processing abnormal offline of local area network instant messaging network node

Abstract

The embodiment of the invention discloses a method, a system and equipment for processing abnormal offline of a local area network instant messaging network node. The method comprises the following steps of: locally establishing a real-time online list and an abnormal offline list; acquiring information of abnormal offline network nodes in the real-time online list; deleting the abnormal off-linenetwork nodes from a local real-time on-line list, and adding the abnormal off-line network nodes into the local abnormal off-line list; issuing an early warning broadcast to other network nodes in the real-time online list, and announcing the abnormal offline network node in the early warning broadcast; and receiving early warning broadcasts issued by other network nodes in the real-time online list. Compared with the prior art, the method has the advantages that the abnormal offline condition of the instant messaging network node can be found, the offline condition is broadcasted to other network nodes participating in instant messaging, broadcast storm is avoided, and flow overhead and network power consumption are reduced.

Description

technical field [0001] The invention relates to the technical field of local area network instant messaging, in particular to a processing method and system for abnormally offline network nodes of local area network instant messaging. Background technique [0002] Such as figure 1 In the shown local area network, each network node participating in instant messaging must establish and save a list locally, as shown in Table 1. This list records the situation of the network nodes participating in instant messaging on the current network: [0003] Table 1 [0004] node name node number Node IP address Test1 1 192.168.0.1 Test2 2 192.168.0.2 Test3 3 192.168.0.3 Test4 4 192.168.0.4 Test5 5 192.168.0.5 Test6 6 192.168.0.6 … … … [0005] If the network node does not have this list locally, then a network node participating in instant messaging must perform a broadcast device discovery before each communication. This...
