Abstract:

Service oriented architectures (SOA) represent a recent proposal to obtain cooperation and interoperability in distributed computing environments. A challenge of SOA is services and resources discovery which can be realized both in centralized and distributed way. The distributed approach involves peer-to-peer (P2P) infrastructures supporting the knowledge distribution among peers. In this paper we propose DNK-WSD, a new network architecture providing an efficient distributed Web service and resource discovery mechanism based on the notification pattern. The DNK network is a peer-to-peer architecture built using the distributed network knowledge (DNK) heuristic which represents a lightweight approach to model graphs mapping logical P2P overlay networks. A case study, regarding the deployment of DNK-WSD for information sharing in real time collaborative Web applications, demonstrates the validity of DNK-WSD in terms of fast propagation of the shared data, low network load and reliability

1. Introduction

In the last years Service oriented architectures (SOA) [9] have been proposed to create distributed applications and computing environments. The service is generally represented by means of the cooperation between web services. Web services

Standards of the W3C are available in http://www.w3.org/2002/ws/

represent an alternative to distributed computing and are being strongly used instead of distributed object middleware such as Java RMI

and CORBA [8].
