This paper presents TCP-PARIS, a novel parallel download protocol from multiple replicas to one receiver. Because the ideal partitioning of the transfer volume from each server is a dynamic and a difficult-to-predict function of network conditions, server load and data size, TCP-PARIS uses the stream segmentation of TCP and congestion window information to continuously adapt the assigned volume to each server in proportion to the bandwidth-delay product to best approximate the optimal data partitioning. Analytical results, simulation and Internet experiments with a transport-layer implementation characterize the performance and the resource requirements of TCP-PARIS and allow a comparison with related protocols. Extensive simulations with varying network and application parameters show download time reductions of up to 52% compared to single-flow downloads and up to 52% compared to related protocols.","PeriodicalId":141241,"journal":{"name":"10th International Workshop on Web Content Caching and Distribution (WCW'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130521923","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 trees, evenly sharing the forwarding responsibility among participants. DHTs seem to be naturally well suited for the task, as they are able to leverage the inherent properties of their routing model in building such a forest. In heterogeneous environments, though, DHT-based schemes for tree (and forest) construction may yield deep, unbalanced structures with potentially large delivery latencies. This paper introduces Magellan, a new overlay multicast protocol we have built to explore the tradeoff between fairness and performance in these environments. Magellan builds a data-distribution forest out of multiple performance-centric, balanced trees. It assigns every peer in the system a primary tree with priority over the peer's resources. The peers' spare resources are then made available to secondary trees. In this manner, Magellan achieves fairness, ensuring that every participating peer contributes resources to the system. By employing a balanced distribution tree with O(lg N)-bounded, end-to-end hop-distance, Magellan also provides high delivery ratio with comparable low latency. Preliminary simulation results show the advantage of this approach.","PeriodicalId":141241,"journal":{"name":"10th International Workshop on Web Content Caching and Distribution (WCW'05)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133673474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 content from exactly one node and uploads the content to exactly one node. Our analysis starts from a complete knowledge about peers, so that we can derive analytically the deterministic behavior and use the results as reference. We then remove part of the knowledge a peer has about its neighbors and derive the performance that can be obtained in such an environment. Results show that, if peers have sufficient information about neighbors, they can be organized in such a way that slow peers obtain near optimal performance without affecting faster peers. On the other hand, if peers do not know neighbor characteristics, slow peers have a significant impact on global performance, and other, more sophisticated, distribution architectures are required to maintain proper scalability.","PeriodicalId":141241,"journal":{"name":"10th International Workshop on Web Content Caching and Distribution (WCW'05)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132736119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
