Distributed Contract Negotiation System for Virtual Organizations

AbstractNowadays, with the broadening usage of distributed systems and Grid, the need for cooperation between many different heterogeneous organizations occurs. Such cooperation usually requires sharing of access to data, service and other tangible or intangible resources. To accomplish such cooperative efforts between organizations, an idea of the Virtual Organization (VO) emerged. It allows the organizations to share resources between the partners, while enforcing proper quality of service and security. In order to enable creation of such Virtual Organization, it is necessary to allow the participants of the VO to negotiation an agreement concerning the rules of cooperation, which will be encoded in a machine processable format. In this paper we present the application of the ESB integration architecture in the specialized distributed contract negotiation service - the FiVO DCNS, which is responsible for distributing contract negotiation events and queries between components of FiVO deployed in different organizations
