“…We denote this storage system as Multi-dir. This is similar to the previous proposals on clustering correlated web objects together for better disk performance, such as in [21]. We extended Multi-dir for P2P traffic to maintain the correlation among segments of the same object.…”

“…This is done to answer the question: "What happens if we were to use the already-deployed web caches for P2P traffic?" To the best of our knowledge, we are not aware of any other storage systems designed for P2P proxy caches, and as described in Section 2, storage systems proposed in [21], [22], [23], [24] for web proxy caches and in [25], [26], [27] for multimedia caches are not readily applicable to P2P proxy caches. Therefore, we could not conduct a meaningful comparison with them.…”

“…Several storage management systems have been proposed in the literature for web proxy caches [21], [22], [23], [24] and for multimedia proxy caches [25], [26], [27]. These systems offer services that may not be useful for P2P proxy caches, e.g., minimizing start-up delay and clustering of multiple objects coming from the same web server, and they lack other services, e.g., serving partial requests with arbitrary byte ranges, which are essential in P2P proxy caches.…”

Abstract-Peer-to-peer (P2P) systems generate a major fraction of the current Internet traffic, and they significantly increase the load on ISP networks and the cost of running and connecting customer networks (e.g., universities and companies) to the Internet. To mitigate these negative impacts, many previous works in the literature have proposed caching of P2P traffic, but very few (if any) have considered designing a caching system to actually do it. This paper demonstrates that caching P2P traffic is more complex than caching other Internet traffic, and it needs several new algorithms and storage systems. Then, the paper presents the design and evaluation of a complete, running, proxy cache for P2P traffic, called pCache. pCache transparently intercepts and serves traffic from different P2P systems. A new storage system is proposed and implemented in pCache. This storage system is optimized for storing P2P traffic, and it is shown to outperform other storage systems. In addition, a new algorithm to infer the information required to store and serve P2P traffic by the cache is proposed. Furthermore, extensive experiments to evaluate all aspects of pCache using actual implementation and real P2P traffic are presented.

Abstract-Caching is a very important issue in distributed web system in order to reduce access latency and server load. A request is a hit if it is available in the cache and if not then it will fetch from the server in order to cache and serve the request. Researches have shown that generic algorithms of caching can increase hit rate up to 40−50%, but adding prefetching scheme can increase this rate to 20%. Prefetching is a technique to fetch documents before they are requested. This paper proposes a process model for prefetching named HitBand which will balance hit rate bandwidth in every scenario with the combination of "Roulette-wheel selection". Roulettewheel selection is a very popular selection based algorithm which selects objects according to their fitness. We have compared our HitBand with the generic algorithms of prefetching like prefetching by popularity, apl characteristic, good Fetch and lifetime. Generic algorithms did not take web object size into consideration and in limited bandwidth scenario object size has a big impact on bandwidth consumption. Though prefetching by lifetime algorithm shows little concern about bandwidth consumption by getting the object with changes happening less frequently but this compromises the hit rate. But our proposed HitBand not only considers bandwidth but also hit rate during prefetching. Performance evaluation of HitBand along with other algorithms is provided in our paper. We have tested our HitBand with the testing engine which is built using JavaScript and maintained under AngularJS framework. From the performance evaluation, our HitBand shows better results both in high and low bandwidth.
