Com a popularidade dos aplicativos P2P do tipo BitTorrent, melhorar seu desempenho tem sido uma área de pesquisa ativa. Super-seeding, uma política de upload especial para o semeador inicial, melhora a eficiência na produção de múltiplas sementes e reduz os bytes de upload dos iniciadores de conteúdo, sendo, portanto, altamente esperada como uma solução promissora para melhorar o desempenho de download e, ao mesmo tempo, diminuir o custo de upload. No entanto, os impactos gerais da super propagação no desempenho do BitTorrent permanecem uma questão e não foram analisados até agora na literatura. Neste artigo, apresentamos um estudo analítico e experimental sobre o desempenho do esquema de supersemeadura. Tentamos responder às seguintes questões: se e quanto a superpropagação economiza custos de upload, se o tempo geral de download é diminuído pela superpropagação e em que circunstâncias a superpropagação tem pior desempenho. Com base no processo de seeding, nosso estudo analítico fornece fórmulas sobre o tempo de distribuição de novas peças, tempo médio de download e tempo mínimo de distribuição para sistema heterogêneo de distribuição de arquivos P2P com super-semeadura. Evidências robustas que apoiam o uso (ou não) de superpropagação são fornecidas com base em nossos experimentos mundiais na Internet em ampla distribuição de 250 nós do PlanetLab. Com um cenário experimental bem projetado, estudamos o tempo geral de download e o custo de upload do esquema de super sementeira sob diferentes larguras de banda de semente e comportamento dos pares. Os resultados mostram que a superpropagação pode economizar uma taxa de upload de 20% e ajuda a acelerar os enxames em certos modos. Conclusões provisórias sobre a eficácia da supersemeadura e suas circunstâncias ideais de trabalho são fornecidas com o mecanismo interno analisado e o fator negativo identificado. Nosso trabalho não apenas fornece referência para a adoção potencial de super-semeadura em BitTorrent e outras aplicações P2P, mas também muitos insights para a luta para melhorar a Qualidade da Experiência (QoE) e economizar custos para um comercial P2P semelhante ao BitTorrent em grande escala. aplicativo.

Abstract: With the popularity of BitTorrent-like P2P applications, improving its performance has been an active research area. Super-seeding, a special upload policy for the initial seeder, improves the efficiency in producing multiple seeds and reduces the uploading bytes of content initiators, thus being highly expected as a promising solution for improving downloading performance while decreasing uploading cost. However, the overall impacts of super seeding upon BitTorrent performance remain a question and have not been analyzed so far in literature. In this paper, we present an analytical and experimental study over the performance of super-seeding scheme. We attempt to answer the following questions: whether and how much super-seeding saves uploading cost, whether the overall downloading time is decreased by super-seeding, and in which circumstances super-seeding performs worse. Based on the seeding process, our analytical study gives formulas on the new piece distribution time, average downloading time and minimum distribution time for heterogeneous P2P file distribution system with super-seeding. Robust evidence supporting the use (or not) of super-seeding is given based on our worldwide Internet experiments over wide distribution of 250 PlanetLab nodes. With a well-designed experimental scenario, we study the overall download time and upload cost of super seeding scheme under varying seed bandwidth and peer behavior. Results show that super-seeding can save an upload ratio of 20% and does help speeding up swarms in certain modes. Tentative conclusions about the effectiveness of super-seeding and its optimal working circumstances are given with inside mechanism analyzed and negative factor identified. Our work not only provides reference for the potential adoption of super-seeding in BitTorrent and other P2P applications, but also much insights for the tussle of enhancing of Quality of Experience (QoE) and saving cost for a large-scale BitTorrent-like P2P commercial application.
