    Most important commercial Web sites maintain multiple replicas of their server infrastructure to increase both reliability and performance. In this paper, we study how many replicas should be used and where they should be placed in order to improve client network performance, including both the latency (e.g., round-trip time) between clients and the replicas, and the bandwidth performance between ...

    Parallel download protocols have the potential to reduce file download time and to achieve a server-side load balancing in replica systems, such as peer-to-peer networks, content distribution networks and mirrored servers, by simultaneously establishing connections to multiple replicas and downloading disjoint file parts in parallel. This paper presents TCP-PARIS, a novel parallel download protoco... View full abstract»

    A growing number of network services are being constructed using the XML Web services architecture. By design, client interactions with such services are governed by open protocols such as UDDI, WSDL, and SOAP that permit programmatic discovery and functionality invocation. Additionally, for a large number of currently deployed services, it is possible to interpret service requests as structured a... View full abstract»

    XML is becoming a ubiquitous format for information exchange on the Internet. To alleviate the problems of "whom to ask" and "whom to tell" when connecting XML information producers with consumers over the network, content-based querying and dissemination of information have been investigated in the literature. Our XTreeNet project unifies the publish/subscribe and query/response models with a sin... View full abstract»

    Recent measurement studies of file-sharing peer-to-peer networks have demonstrated the presence of semantic proximity between peers and between shared files. In this paper we tackle the problem of exploiting the semantic locality of peer requests to improve the performance of a P2P network by the use of semantic caches. Such caches group together peers with similar interests as well as files with ... View full abstract»

  • DOMProxy: enabling dynamic-content front-end Web caching

    Proxy caching is a commonly accepted methodology used to reduce Internet traffic, decrease back-end related user delays, and generally improve Web performance. Nevertheless, it seems to be inadequate when it comes to caching dynamic Web pages, due to their low degree of reusability and strong dependency on the back-end site infrastructure. In order to overcome these drawbacks we present DOMProxy (... View full abstract»

  • Content-aware global static compression for Web content delivery

    The effectiveness of real-time lossless compression on Web data is found to be limited by the relatively small size of its basic operation unit, Web object. However, we observe that while the repeated occurrence frequencies of strings within a single object might be low, the frequencies can be very high if they are considered over multiple objects. Furthermore, these strings with high occurrence f... View full abstract»

    In scenarios where recorded presentations are streamed to a group of clients, users prefer to control streaming on demand and to get content in an individually adapted fashion. IP multicast, the obvious solution for group streaming, cannot provide such a level of flexibility. End-system multicast approaches alleviate the need for multicast routing, but require more powerful clients and are more co... View full abstract»

    Considering the constant increase of network traffic, and existing bandwidth limitations, caching Internet objects is an essential technique to improve the provided quality of service and to reduce the network load. Caching is particularly helpful for video objects due to their interactive nature, large size, long playback duration, real time constraints, and typically variable bit rate. Several c...

    Streaming media has experienced explosive growth over the last few years and will continue to increase in popularity as individual users can easily produce digital images and video. Large scale streaming will require network operators to deploy and manage a larger number of streaming servers within their networks. In order to determine the number of servers needed, and to design the appropriate ma... View full abstract»

    Large swings in the demand for content are commonplace within the Internet. When a traffic hotspot happens, however, there is a delay before measures such as heavy replication of content can be applied. This paper investigates the potential for predicting hotspots sufficiently far, albeit shortly, in advance, so that preventive action can be taken before the hotpot takes place. Performing accurate... View full abstract»

    In this paper we propose a stochastic fluid model to analyze the performance of Squirrel, a P2P cooperative Web cache. This work provides a scalable and insightful extension of our previous analysis of Squirrel. This new model provides a closed-form expression for the hit probability when documents are equally popular. Realistic object popularity is also addressed through a clustering approximatio...

    Performance analysis of P2P systems is necessary to understand the real impact on the network of such applications. In this paper we study the performance that can be achieved by a simple file distribution architecture in a heterogeneous environment, i.e., when the access links of peers have randomly distributed capacities. The distribution architecture is a chain, where each peer downloads the co... View full abstract»

    Wireless broadcast networks are currently widely deployed to connect users to their Internet providers, but only point-to-point services are typically used over these networks. Multicast Web caching is a readily-available technique embracing the broadcast capabilities of wireless links and benefiting from them. However, certain trade-offs of full multicast Web caching must be taken into considerat... View full abstract»

    Among the proposed overlay multicast protocols, tree-based systems have proven to be highly scalable and efficient in terms of physical link stress and end-to-end latency. Conventional tree-based protocols, however, distribute the forwarding load unevenly among the participating peers. An effective approach for addressing this problem is to stripe the multicast content across a forest of disjoint ... View full abstract»

    The FLUTE file delivery application (RFC 3926) and the underlying massively scalable reliable multicast protocol, ALC (RFC 3450), are used for the scalable distribution of contents in a broadcasting system having no feedback channel. When used in a routed network (like the Internet), a layered congestion control protocol is required. This paper analyzes the impacts of the startup behavior of sever... View full abstract»
