Semantic Resource Description for Grid

Abstract: Matching resources is a fundamental problem within large scale distributed environments such as Grid for which the critical process is resource discovery and description. An effective way of solving this problem is providing meta-data about the resources. Ontologies can be used to capture metadata information. Ontologies determine the terms of Grid entities, resources, capabilities and the relationships between them with meaning by the addition of ontological annotations. In this paper we present the initial design of resource description ontology. This ontology can be used for solving resource matching for Grid using semantic Web technologies

Introducing semantics in DHTs for Grid services in a semantic registry

Abstract: The Grid is growing with its large number of users and services that are being published by its publishers. The dilemma is to handle the meaningful information that is the metadata of Grid services. The metadata can then be used for the automatic processing of the Grid services. In this era we can describe and associate information to the services by using ontology languages such as OWL. With the growth of the Grid services, the metadata of services need to be highly significant and this necessitate for a semantic grid services registry that registers the services handling the scalability and reliability semantically. The usefulness of the Grid services is only if registered by service providers and the consumers can efficiently discover. We propose a semantic Grid service registry offering scalability and reliability to the semantically enriched services published and discovered in and from the semantic registry as well as managing the registry growth and its self based organization with the help of semantic DHT (Distributed Hash Table) based overlay network. It basically assists the service providers to register their services along with the services users to search and subscribe for the grid services semantically. In this paper we evaluated our architecture by managing massive number of users and decentralizing and distributing the semantic metadata information exploiting the DHTs. Semantic Grid service registry is capable to publish, discover and subscribe to different domains of the grid services.

Design and development of a semantic information modelling framework for a service oriented optical internet

Abstract: The evolution of IT and network technologies has generated far-reaching opportunities for complex service innovation in future Internet. This has resulted in an increase in the heterogeneity and complexity in service provisioning. Such complex services demand efficient coordination of distributed IT resources (storage and computing) interconnected by high capacity optical networks. This paper proposes a service plane architecture as an architectural enhancement promising to handle these complexities. It implements a unified service provisioning concept that can adapt to the heterogeneous, dynamic and complex nature of emerging service requirements as well as optical network and IT resource capabilities. The main elements of the proposed architecture consist of information discovery and service discovery that require a semantic modelling framework to address heterogeneity and automation. This paper introduces the novel semantic modelling framework, which is used for information description in a service-oriented environment based on Web Services Modelling Ontology (WSMO). The framework describes the information model and entities needed to communicate requirements for autonomous, homogeneous service discovery, selection and composition.

Autonomic Model for Service-Aware Storage

Abstract: The administration of resources and application scheduling in a large-scale distributed storage environment is a formidable task nowadays, especially in dynamic changing scenario both in storage resources and application requirements. In order to make a difference in application oriented storage service, this paper shows a new autonomic approach to match individual applications to most appropriate storage systems and storage services based on their particular characteristic matrix, such as capacity, performance, availability, dependability, recoverability, user requirements, scalability, and value to the organization etc.

A Semantic Framework for Resource Discovery Based on Ontology

Abstract: In this paper, we propose a better solution to the limitations involved by using the current standard of syntactic matching for resource discovery in Grid environment. Our observations noted that syntactic matching was limited in its ability to use all available resources. In order to overcome these limitations, we hereby propose a method for resource discovery involving semantic matching based in ontology and explain the industry’s available tools that were involved in implementing this structure. After clearly presenting all aspects of the structure and how to implement it, we offer the results from various simulations, which clearly demonstrate the greater results obtained through semantic matchmaking. In conclusion, we take a brief look at some of the future work that will be possible as a result of our findings.

Semantic Grid service registry

Abstract: The vital problem of grid community today is to cater the metadata information of Grid services and to exploit it for the automatic processing. Now-a-days describing and associating information to the services is accomplished by using ontology languages. The Grid services are growing and the information of services need to be highly expressive, for that purpose the wide use of grid services results in the need for a scalable and fault tolerant semantic grid registry. The services are useful only if registered by service providers and discovered by the consumers. Our proposed scalable and fault-tolerant semantic grid registry provides semantically enriched services to be registered and discovered as well as handling the growth of the registry and the self healing in a semantic DHT based overlay network. It facilitates the service providers to register their services and the consumers to discover and subscribe for the grid services semantically. The semantic grid registry is highly scalable and fault-tolerant exploiting the DHTs (Distributed Hash Table) by managing massive number of users and decentralizing the semantic information. Semantic Grid registry can be used to publish and discover any type of grid services.
