“…Specification matching is, however, performed between the pre-conditions and post-conditions of the functional semantics of software components using automated theorem proving or query containment. Semantic matching has been applied to a number of distributed systems, including Grid computing [21,22], P2P computing [23,24], Web Services [25], and pervasive computing [10].…”

Abstract. As the Cloud computing appears to be part of the mainstream computing in a few years, the number of the services it provides, its users, and the requests of these services will be on the rise accordingly. To deliver satisfactory experience to Cloud users, it is essential that highly scalable techniques for service discovery should be available. We embarked on a preliminary study, in Cloud environments, on service discovery by adopting an unstructured P2P technique. In the context of Cloud computing, we start by examining proposed and deployed solutions to service discovery, discuss the methodology of developping efficient mechanisms for service description, description indexing, and query routing, and finally identify open issues.

“…A scalable reputation model is incorporated to rank Web services based on both trust and service quality. [12] presents PSWD, a distributed Web service discovery architecture based on an extended Chord algorithm called XChord. PSWD uses XML to describe Web service descriptions and to express the service requests.…”

Service-oriented computing is emerging as a paradigm for developing distributed applications. A critical issue of utilising service-oriented computing is to have a scalable, reliable and robust service discovery mechanism. However, traditional service discovery methods using centralised registries can easily suffer from problems such as performance bottleneck and vulnerability to failures in the large scalable service network, thus functioning abnormally. To address these problems, this paper proposes a peer-to-peer based decentralised service discovery approach named Chord4S. Chord4S utilises the data distribution and lookup capabilities of the popular Chord to distribute and discover services in a decentralised manner. Data availability is further improved by distributing service descriptions of functionally-equivalent services to different successor nodes that are organised into a virtual segment in the Chord circle. In addition, the Chord routing protocol is extended to support efficient discovery of multiple services with single request. This enables late negotiation of service level agreements between a service consumer and multiple service providers. The experimental evaluation shows that Chord4S achieves higher data availability and provides efficient query with reasonable overhead.

Abstract-Service-Oriented Computing (SOC) is emerging as a paradigm for developing distributed applications. A critical issue of utilizing SOC is to have a scalable, reliable, and robust service discovery mechanism. However, traditional service discovery methods using centralized registries can easily suffer from problems such as performance bottleneck and vulnerability to failures in large scalable service networks, thus functioning abnormally. To address these problems, this paper proposes a peer-to-peer-based decentralized service discovery approach named Chord4S. Chord4S utilizes the data distribution and lookup capabilities of the popular Chord to distribute and discover services in a decentralized manner. Data availability is further improved by distributing published descriptions of functionally equivalent services to different successor nodes that are organized into virtual segments in the Chord4S circle. Based on the service publication approach, Chord4S supports QoS-aware service discovery. Chord4S also supports service discovery with wildcard(s). In addition, the Chord routing protocol is extended to support efficient discovery of multiple services with a single query. This enables late negotiation of Service Level Agreements (SLAs) between service consumers and multiple candidate service providers. The experimental evaluation shows that Chord4S achieves higher data availability and provides efficient query with reasonable overhead.
