Abstract:
Peer-to-Peer service discovery is the norms of today’s Service Oriented Architecture. Efficiency and scalability of these systems are adversely affected by the type of distributed architecture, the query routing mechanism and the effective usage of underlying network topology. Traditional query routing mechanisms in distributed P2P systems function purely at the overlay layer by isolating itself from the underlying IP layer that degrades the performance due to large amount of inter-ISP traffic and unbalanced utilization of underlay network links. In this paper we address this problem by proposing novel distributed service discovery architecture, which enhances underlay awareness without the involvement of the overlay peers. Our design starts from the underlay layer, which is built on top of Application Oriented Networking (AON) backbone that exploits message level routing. This feature is further leveraged in the overlay layer with industry based classification of published services, which complements the process of message level routing. We present the conceptual design of our framework and analyze its effectiveness. We argue that both performance and scalability of the system are drastically improved by moving down the overlay query routing mechanism to the IP layer.
