Abstract: The publish/subscribe paradigm provides a very effective and reliable scheme to implement Peer-To-Peer (P2P) networks. In these systems, the reduction of the number of messages associated to the searching procedure is a crucial issue. In this paper, we study the current publish/subscribe systems and propose an Optimised Middleware (OMCPS), suitable for the implementation of large-scale content delivery systems. The main idea behind our proposal is to reduce the conventional message distribution and searching process by using a well-known decentralised algorithm (the Chord). In addition, the internal OMCPS organisation among the Servers that conforms the P2P system is transparent to the consumer and supplier applications.

Keywords: middleware; structured P2P networks; peer-to-peer networks; publish-subscribe architecture.
