A Grid-Enabled Value-Added Service Platform in NGN and Model
融合网格的NGN增值服务平台及建模分析

This paper introduces a value-added service platform in Next Generation Network(NGN) enabled by grid technology to solve the performance issue with traditional application server in NGN. All of the value-added services hosted by this platform are wrapped into grid service. This platform provides running environment to value-added service in NGN. A grid-based task scheduling algorithm is also proposed with this platform. This grid-based task scheduling algorithm can solve the system performance bottleneck problem when system gets overload by leveraging existing resources in the same virtual organization with the help of grid technology. This paper models the service platform using Stochastic Petri Net(SPN) ,and the simulation experiment is done with SPNP(Stochastic Petri Net Package) to test the performance of the service platform according to this model. The simulation result verifies the platform can achieve the goal of improving the system performance.
