Abstract
The Web is rapidly increasing its reach beyond the desktop to various devices and the transcoding proxy is appeared to support web services efficiently. Recently, the cooperative transcoding proxy architecture is proposed to improve the system performance to cope with the scalability problem of a stand-alone transcoding proxy. However, because of the multiple versions, the communication protocol of the cooperative caches is very complex and causes additional delay to find best version for a requested object.
In this paper, we propose efficient cooperative transcoding proxy architecture which uses the content-aware caching. The main purpose of the proposed system is simplifying the communication protocol of cooperative caches. We associates a home proxy for each URL and the home proxy is responsible for transcoding and maintaining multiple version of an URL. This mechanism reduces the amount of messages exchanged and communication latency involved. To prevent the hot-spot problem, each proxy cache has the private cache which stores the recently requested objects. We examine the performance of the proposed system by using trace based simulation with Simjava and show the effective enhancement of the cooerative transcoding proxy system.
