Service-based P2P overlay network for collaborative problem solving

Abstract: This paper describes a service-based P2P overlay network architecture to support a collaborative environment for solving complex business processes over the network. In the proposed architecture, autonomic service providers corresponding to various activities that occur in the processes reside on the overlay network and are discovered dynamically during the execution of the process. To consummate a specific process, a set of services that map into the business process are federated together and executed in a choreographed sequence. All services have standardized interfaces and this allows any service to be seamlessly replaced with another service without affecting the performance of the federation. The paper presents two cases of application of this architecture, namely, business-to-business collaboration in an engineering environment (General Electric) and multiparty financial transactions (mortgage).

Codifying a service architectural style

Abstract: We discuss what constitutes a 'software service model' and propose a framework that can accommodate both component-based and service-based systems, while also distinguishing between 'static' and 'dynamic' forms of service delivery. We then draw upon this, and upon our own experiences of developing service-based forms, to consider what characteristics a service architecture might possess

Service Grid Federation Architecture for Heterogeneous Domains

Abstract: Service grid is an infrastructure for service-oriented collective intelligence. It provides a set of enabling functionalities to support coordination of services, such as service registries, service composition, access control, and monitoring. To form the service-oriented collective intelligence, various types of services need to be connected on the service grid, and managed by the service grid operator. However, it is difficult for single service grid operator to gather and organize services in various domains. Therefore, building service grids in different domains and connecting these service grids are essential for expanding service-oriented collective intelligence across domains. To this end, we have designed a service domain model to specialize general-purpose service grid to a specific domain and realize interoperability among service grids. Moreover, we have also developed service grid federation architecture to share service registries, compose services across service grids, and control and monitor accesses to the composite services. Finally, we have applied the proposed architecture to the language service domain to construct the Language Grid.

Complex service modeling

Abstract: A deal management system is used to manage a complex service deal that defines various services to be fulfilled on behalf of a client. The deal management system includes a deal specification subsystem, a cost subsystem, and an estimation subsystem. The deal specification subsystem has a new deal interface to facilitate user specification of the complex service deal, including a plurality of service elements scheduled for fulfillment from a plurality of service delivery centers. The cost subsystem tracks an aggregate cost of a service delivery center that is arranged to fulfill a particular service element. The estimation subsystem dynamically evaluates accuracy of a deal cost model for the complex service deal during a duration of the particular service element by establishing a correlation between particular service elements within the complex service deal and portions of the aggregate cost data allocated to the corresponding service delivery center.
