<p><P>PROBLEM TO BE SOLVED: To provide a communication control process executing method and system that can quickly respond for a connection request processes even in a high-load state and improve the tolerance of a server to a load. <P>SOLUTION: For a call process server on an IP network, two kinds of queues 60 and 70 or more which differ in priority are prepared in a call process buffer, and then the connection request process is performed preferentially to a disconnection request process. When a call process task extracts events from the queues 60 and 70 to perform a next process, priority control over the extraction order is performed between the queues 60 and 70. Similarly to a packet transfer process of a router, a scheduling algorithm such as PQ and WRR is applied to preferentially process a process request call whose response time condition is strict. Here, Tp is a time needed to process each request call, Tq is an average wait time of the queues, and (s) is the number of processes that the server can process simultaneously. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
