CACHE COHERENCY CONTROL BY USING MOESI PROTOCOL IN ONLINE DOCTOR APPOINTMENT

Abstract

The rapidly growth of internet and the World Wide Web have made the possible for millions of users to gain access to geographically distributed web content. However, raising the population of online users and the unbalanced use of content accesses, popular objects may cause server and network overload and increase the latency for content access significantly. Caching is a common technique to reduce content access latencies. In caching system, data items are retrieved from the server machines, cached and processed at the client machines, and then write back to the server. This system controls the cache consistency by using MOESI protocol in online doctor appointment. This appointment system allows patients to get an appointment with doctor from any time at anywhere using mobile devices and internet service Wi-Fi, Dial-Up, Broadband, DSL, Cable, Satellite, ISDN. It can control the concurrent processing and save the waiting time not only for the users but also make the appointment process efficient.
