摘要:

在非结构化对等覆盖中的可扩展性和高效的全局搜索在文献中得到了广泛的研究。全局搜索是以牺牲对等点之间的本地交互为代价的。大多数非结构化对等覆盖不提供任何性能保证。在这项工作中,我们提出了一种新的服务质量启用查找非结构化的对等覆盖,将允许用户的查询遍历只有那些覆盖链接,满足给定的约束。此外,它还通过明智地使用覆盖资源来提高可扩展性。我们的方法选择性地转发查询使用QoS指标,如延迟,带宽和覆盖链路状态,以确保在对等加入和离开的程度很高的情况下,提高性能。用户只得到那些可以在给定约束条件下下载的结果。此外,该协议的目的是在覆盖网络上的消息开销最小化。

英文摘要:

Scalability and efficient global search in unstructured peer-to-peer overlays have been extensively studied in the literature. The global search comes at the expense of local interactions between peers. Most of the unstructured peer-to-peer overlays do not provide any performance guarantee. In this work we propose a novel Quality of Service enabled lookup for unstructured peer-to-peer overlays that will allow the user's query to traverse only those overlay links which satisfy the given constraints. Additionally, it also improves the scalability by judiciously using the overlay resources. Our approach selectively forwards the queries using QoS metrics like latency, bandwidth, and overlay link status so as to ensure improved performance in a scenario where the degree of peer joins and leaves are high. User is given only those results which can be downloaded with the given constraints. Also, the protocol aims at minimizing the message overhead over the overlay network.
