Abstract: Existing P2P systems are mostly confined to the domain of file sharing, which in many aspects differ from decentralized E-Commerce. In this paper, we propose a decentralized E-Commerce oriented service discovery system, named SOUNDE. The system is a two-layer architecture, with the upper layer composed of many E-Commerce Domains forming a DHT-based topology, then each Domain composed of the related peers in that specific Domain, forming an unstructured topology which applies SophiNode service discovery algorithms. Meanwhile, we also put forward GovNode, which plays the role of joint between the two layers. At the end, we present our simulation and analyze the results.

Key words: Decentralized E-Commerce, Peer-to-Peer, Service Discovery, SOUNDE

摘要： 由于分布式电子商务的特殊性，现有的对等网搜索机制无法有效地被应用。因此本文提出了一种面向电子商务的服务发现系统，这个系统可以是一个两层的结构，上层由许多的电子商务域组成一个基于DHT的结构，而下层则是每个商务域中的相关节点组成的非结构化拓扑，采用成熟节点搜索算法。同时，我们还提出了一个两层之间的连接节点结构。本文最后，描述了实验并分析了实验数据。
