Design And Implementation Of The Multi-Task Simulation Platform Based-On Distributed Service Network

The mobile communication and Internet industry is developing very fast in recent years, which has become a very important part of people’s daily life. At the meanwhile, with the rapid development of China’s3G mobile network, the era of Mobile Internet has come.In order to meet the high demand of Mobile Internet, China Mobile has proposed The Distributed Service Network (DSN) for Mobile Internet as a set of core network architecture for the convergence of the telecom network and the Internet. Before deploying any kinds of business on the DSN, we must firstly do the corresponding business simulation. However, the existing simulation platform of the distributed service business can only do the simulation for a certain business, and these platforms can’t support the specific QoS simulation in the telecommunications network. What’s more, the existing network simulation platform can’t simulate the algorithms of the distributed business and new business.Therefore, in order to provide a powerful accurate theory support and practical reference for the new business network and its corresponding application deployment, we designed and implemented the multi-task simulation platform based on the DSN network.In order to successfully complete the design and implementation of the simulation platform, fully research of the related technology is done previously. This paper firstly puts forward the integral design of the multi-task simulation platform according to the DSN business characteristics and illustrates the hierarchical structure of the multi-task simulation platform. Secondly, a performance evaluation model is proposed to build the performance evaluation system according to the characteristics of simulation platform. After that, this paper gives a detailed instruction on the P2P-Download Subsystem of the multi-task simulation platform, including the user behavior model, the specific network structure, the entity message definition and detailed business process. Finally, through the specific scene test, we check and analysis the various performance indicators of the P2P-Download Subsystem to verify the reliability and stability of the system.
