....one is to find the best replica server for each client. To maintain consistency among the documents at replica servers is another important issue. In the following few subsections we discuss some of the approaches proposed for implementing replication. Wide Area File System Spasojevic et al. [19] proposed using an underlying wide area file system (e.g. AFS [15] for speeding up web access. The basic idea is that some documents may be accessible to the client through a locally mounted wide area file system. This leads to lesser load on the web server since the clients use the file system ....

....currently gaining popularity in the Web. An interesting approach is to keep client caches up to date by have servers invalidate entries on updates [4] This approach is also followed in AFS, of which the designers claim it can be used as the basis for building strongly consistent Web applications [26]. Research has also concentrated on replication schemes for specific classes of Web resources. For example, the distribution point model [7] is tailored to active replication of relatively static sets of bulk, non real time data. It is mainly applicable to magazine like Web documents such as those ....

....by all caching mechanisms along the transfer path. These directives will identify cacheable files, non cacheable files, private files, and TTL values [8] Many problems similar to those facing World Wide Web researchers have been tackled by researchers in wide area file systems. Spasojevic et al. [63] suggest using a wide area file system, such as the Andrew File System (AFS) within the World Wide Web. AFS has built in mechanisms for caching, replication, location transparency (i.e. a global name space) and authentication, which facilitate improved performance, reliability and security. ....

....(i.e. a global name space) and authentication, which facilitate improved performance, reliability and security. Spasojevic et al. also found that the AFS transfer protocol Rx performs better than HTTP, as Rx requires less state to 20 establish a connection, and uses bandwidth more aggressively [63]. 3.5 Summary The World Wide Web, a globally distributed application, is growing rapidly. As this growth continues, efficient Web clients, servers, proxies, network links, and protocols become increasingly important. Other research efforts are currently looking to improve the efficiency of Web ....

....File System This approach has technical appeal. Many of the performance and access control problems of using the Web to access files are similar to the problems faced by a distributed file system (DFS) In the author s opinion, the currently available distributed file systems (e.g. see [2]) come with such a heavy administration and configuration burden, have so little current market penetration, and currently require such awkward name mapping support for WWW access that this approach isn t ready to significantly help WWW performance. It is worthwhile to begin testing WWW access ....

....has sparked much research activity on improving the World Wide Web. For example, researchers have proposed caching strategies for Web clients [3] caching strategies for Web servers [4] regional file caching strategies for large internetworks [8] and improved protocols for Web interaction [15, 20]. Much of this recent research activity has been aimed at improving Web performance and scalability. The key performance factors to consider are how to reduce the volume of network traffic produced by Web clients and servers, and how to improve the response time for WWW users. Fundamental to the ....

....recent study at Boston University [3] studied the effects of client level caching on Web performance. Several other researchers have studied the use of file caching to reduce network traffic and server loads [4, 8, 10] Web performance can also be improved by enhancing client server communication [15, 20]. Although the primary focus of this paper is workload characterization for Web servers, several relevant issues affecting server caching and performance are discussed in Section 5. Client and network performance issues are outside the scope of this paper. 3 Data Collection, Reduction, and ....

....caching being the most effective way to reduce latency. Furthermore, both papers point out the need for naming conventions and name resolution protocols that provide location and replication transparency. The use of a wide area file system for storing and retrieving WWW documents is proposed in [10]. Widearea file system features of location transparency, access control lists, authentication, client caching, data replication, and file migration are suggested for improving performance, decreasing server and network load, and increasing security. Based on their analyses of WWW client and ....

The dramatic increase in data sharing exposes problems of increased server and network load, high latency, and inadequate security. A recent study on using a wide area file system within the World Wide Web [23] demonstrates that most of the functionality of the Web service can be implemented by storing documents in AFS. A simple modification in the Web client facilitates retrieving documents, whenever possible, through a wide area file system. This allows utilization of wide area file system features in ....
