<title>Novel cluster proxy server system for Internet applications</title>

The performance improvement on SIP-based VoIP server is given in this paper. The signaling server “SIP Proxy Server” and media streaming server “Media Relay Server” are applied. Firstly, the performance of VoIP server is analyzed and evaluated in detail. Then the effective method is applied to improve the performance of VoIP server. In the analysis results of SIP Proxy Server, the CPU time for the registration and call-setup sessions need 3.241 ms and 7.985 ms respectively. Moreover, in the Media Relay Server system, when the packet size from 1 to 32 bytes, the maximum throughput of packet is about 82,000 and 16,000 per second for UDP and TCP respectively. The large the packet, the less throughput is tenable. There are three methods applied to improve the performance. The capacity by 31 times is achieved. The capacity with 3,524 calls for each Media Relay Server is achieved. The improved method proposed in this paper is reasonable.

The Web

The performance of web processing needs to increase to meet the growth of internet usage, one of which is by using cache on the web proxy server. This study examines the implementation of the proxy cache replacement algorithm to increase cache hits in the proxy server. The study was conducted by creating a clustered or distributed web server system using eight web server nodes. The system was able to provide increased latency by 90 % better and increased throughput of 5.33 times better.

Content Cache

Numbers of internet users are increasing incredibly fast. Ideally, this increasing numbers of users are also supported by capacity uplift, in this case an increase in bandwidth to maintain the standard services that received by the users. However, increasing the bandwidth not always becomes the first option since it is quite expensive. Implementing proxy server as content/cache engine is the other option available. It will cache the content that user requested and keep it for a while for servicing the other users that will request the same content in the future. WCCP protocol is used to redirect user’s traffic to the proxy server. The standard proxy server configurations are using single router with one or more proxy servers. This thesis is aims to design and implement proxy server system with multi routers configuration. Multi routers configuration is used as a failover mechanism to provide network high availability. It will use HSRP protocol to provide the high availability services. Tests that conducted after implementation shows the increase in transaction and successful transaction by 296% and 284% also a decrease in response time as well as failed transaction by 18% and 99% consecutively. Failover test shows the percentage of packet loss amounted to 31,3% and 26,3% for clients in VLAN 10 and VLAN 20 consecutively. The average time required for clients to reconnect to the internet after router failure is 7 seconds for clients in VLAN 10 and 6 seconds for client in VLAN 20.
