CACHE CONSISTENCY MAINTAINING METHOD ON WIRELESS INTERNET CIRCUMSTANCES

摘要

The invention from a disconnection and disconnection between relates to maintaining cache consistency method in a wireless Internet environment, the conventional cache coherence methods with less algorithm is suitable for a wired Internet environment that does not cause disconnection, however, the client and the server in the wireless Internet environment for returning the frequent and receive server and the control information for each time that the client does not receive an invalidation message is provided by the server to return from the disconnection to determine the consistency whether the cache data for all data must manually check whether updates so gives a burden on the server and the communication channel, there are problems that do not respond quickly to your needs. In the present invention, considering the problems will give will send the any were placed on the disconnection state of a client in a wireless environment, if the server that the client was managing matters related to the cache coherence reconnect solely the information needed to maintain cache coherency wireless by providing cache coherence method in Internet environment by reducing unnecessary control information transfer between reconnect the client and the server to reduce the burden on servers and channels, there is an effect that the client is quicker to respond to your request.
