摘要：Content-Based Publish/Subscribe system is an important emerging communication paradigm in e-commerce applications. The distribution of contents to the Subscribers in a scalable way is a very important requirement of these applications. However, the centralized structure of system limits its performance and the scope of nodes by which users get information from. This paper describes publish/subscribe system over peer-to-peer, which provides users an easy method of access to information. The schema of system has been improved in two aspects. First, we present a content-based filter algorithm with multi-threshold to minimize the amount of routing and data transferring. Second, a method initializing above thresholds and ensuring access quantity is designed. Results show that model can efficiently improve the system performance, and algorithm is flexible and robust. ?2009 IEEE.
