Abstract

This paper researches the resource sharing problem in Next Generation Network (NGN). GRSEN-an OGSA-based Resource Sharing Environment in NGN is proposed which is divided into four layers: resource layer, service layer, virtual service and virtual organization layer (VSVOL) and the user/application layer. GRSEN wraps all the resources in NGN including network capability resources, service resources into grid services. With the help of VSVOL, GRSEN realizes the transparency of the access to grid service in NGN. A multiserver multiqueue (MSMQ) based scheduling system of GRSEN and a priority-based scheduling algorithm are proposed. The proposed scheduling system is modeled by Stochastic Petri Net and simulation experiments are done. The results of experiments verify that the scheduling system and algorithm can achieve the goal that scheduling service requests of GRSEN according to the priority and getting large throughput.
