面向电子商务的P2P发布/订阅系统

A Peer-to-Peer Publishing/Subscription System for E-Commerce

当前的电子商务(E-commerce)大多采用传统的B/S结构,同时向用户提供站内的搜索引擎,但事实上电子商务的资源很多时候是分散并且动态的,因此造成了网络拥堵、可靠性低和使用不便等问题。针对上述问题,提出将电子商务迁移到P2P网络环境下,并使用发布/订阅系统代替搜索引擎,以适应网络资源分散和动态的特点。在现有的发布/订阅系统中融入基于内容的多权值过滤算法,提高了系统的性能和信息反馈准确率。数值实验表明:改进的系统将使商业模式更加人性化,网络负载更加平衡,具有更强的鲁棒性。

The common E-commerce uses the traditional structure, B/S, which provides search engine for users. However, at most of the time, the resources of E-commerce are distributed and dynamical, which result in many problems such as crowded network and low reliability. To overcome these problems, this paper proposes to move E-commerce to P2P environment, and replace the search engine with publishing/subscription system. Furthermore, a new filtering algorithm with multi-threshold based on contents is integrated into publishing/subscription system to improve the performance and the correct rate of feedback information. The numerical experiment results show that the more personality and robustness can be provided, and the load balance of system can be improved.
