Title： Realizing the Scalable Service Provisioning in Ubiquitous Networking Environment(uGrid) by Extending Routing Protocol
Abstract： With the advance of ubiquitous society, it is expected that everything will be allocated IP address and connected to the network. In a ubiquitous grid networking environment(uGrid) we have proposed, we define not only devices but also program functions and contents as“ Service-Part ”by allocating IP address. uGrid provides mush-up desired service for users along the flow of service by interconnecting various Service-Parts. Because we allocate IP address to Service-Parts we can manage Service-Parts within Network layer. Then, we propose a new system“ Service-Routing ”by which service provision in uGrid scales all over the world. In proposal, we propose the Network System where Service-Parts advertise the Service Cost in the same way routers advertise the link cost, which is feasible by extending OSPF. By calculating the route of the flow of service in this system, appropriate service provision that is not achievable with application layer can be realized. Thus, additionally, we propose routing
scheme of flow of service by ILP(integer linear programming) and extending Dijkstra method. We evaluated the effectiveness of proposal by computer simulation.
