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.
