Architecture of a web accelerator for wireless networks

摘要

With the continuous growth of mobile users and web-based wireless applications, the performance of accessing web services via wireless is becoming one of the key issues. Regular TCP has many problems to tackle wireless connections. Especially for 2.5G or 3G mobile users, the bandwidth is always limited to access various IP applications. In this paper, we describe the design, implementation and evaluation of a web accelerator. Our proposed web accelerator increases the web pages retrieval speed and maximizes bandwidth utilization of TCP/IP application to overcome the obstacles of wireless networks. This goal has been achieved by two solutions: first, replacing TCP with Boosted TCP Protocol (BTCP) to improve the performance of TCP over wireless; second, compressing the web content to make it efficient for various wireless devices.
