....of the Internet, thus decreasing the distance between clients and web content. It can significantly reduce network congestion, server load and access delay. A huge amount of research effort has been devoted to all aspects of web caching, and various caching schemes have been proposed [4] 9] 11] [13] [16] 19] 22] Effective caching requires cooperative content management of web caches. Traditional caches include clients, proxies and servers. One common approach to coordinate caches is Hierarchical Caching [7] 16] where a cache hierarchy is set up and caches are located at different ....

....UDP Protocol (ARDP) T TCP, and P TCP. The major performance metrics used in these work was transmission time of the whole page. As discussed in the previous sections, this measurement may not reflect the overall perception of end users. Using UDP to transmit Web traffic has been explored in [5, 17]. A simulation study in [5] has revealed the performance improvement under various link conditions by using UDP to transfer Web pages. A implementation based study in [17] proposed a hybrid TCP UDP protocol that exploits the lightweightedness and caching friendliness of UDP under low lossy links ....

A implementation based study in [17] proposed a hybrid TCP UDP protocol that exploits the lightweightedness and caching friendliness of UDP under low lossy links and switches to TCP otherwise. The major concerns in these studies are how to exploit the lightweight UDP to expedite the delivery of HTML pages and the extended caching ....

....cases where the computer cannot provide fairly immediate response, continuous feedback should be provided to the user in form of a percent done indicator. There have been some research initiatives that investigate the feasibility of using UDP as the transportation protocol for web traffic [6] [21]. UDP is connectionless and thus a lightweight alternative to TCP. There are no obligatory ACKs in UDP and request redirection or handover among multiple servers do not require the setup of new connections. On the other hand, the constraint of tag matching in rendering Web pages also contributes ....

....any redundancy in HTML pages. For a duration of three days with 11,000 requests, an Internet wide test was conducted from Michigan State University to UC Davis. There are 17 hops along the path with an average RTT of 70ms. Since the performance comparison between TCP and UDP was presented in [21], we only compared our scheme with UDP only protocol. We set the retransmission timeout as 1 second and chose a 10KB document size with 5 data frames to avoid injecting too much traffic to the network. It was discovered that during our test most of the connection did finish quickly with about 130 ....
