TheWeb server can keep the data as persistent objects in no demand of external database ,support types of devices such asPC, PDA, mobile phone etc. in wired/wireless mode through the lowest bandwidth of 9.6K/s and is linear scalablewith Zero Friction Engine. It's a thoroughly new resolution compared with the others.展开更多

Packet Single-Rewriting technology and client address hashing algorithm in ONE-IP technology which can ensure application-session-keep have been analyzed, an improved request dispatching algorithm which is simple, effective and supports dynamic load balance has been proposed. In this algorithm, dispatcher evaluates which server node will process request by applying a hash function to the client IP address and comparing the result with its assigned identifier subset; it adjusts the size of the subset according to the performance and current load of each server, so as to utilize all servers' resource effectively. Simulation shows that the improved algorithm has better performance than the original one.展开更多
