Abstract

The surge of Internet traffic makes the bottleneck nowadays. This problem can be reduced by substituting the media of network, routers and switches with more high-performance goods. However, we focused radically the server performance of processing the service requests. We prepose the method improving performance of server in the Linux kernel stack. This accelerator accepts the requests from many clients, and processes them using not user threads but kernel thread. To do so, we can reduce the overhead caused by frequent calling of system calls and the overhead of context switching between threads. Furthermore, we implement CPN(Coloured Petri Net) model. By using the CPN model criteria, we can analyze the characteristics of operation times in addition to the reachability of system. Benchmark of the system proves the model is valid.
