摘要
为多业务类的下一代网络合理分配网络资源,优化全网效应是实现下一代网络QoS保证的重要途径。首先提出了基于合作博弈框架的下一代网络资源优化分配方法,提高下一代网络全网效应,并提供网络业务的有区分QoS保证。进而分析该方法存在的系统开销过大的问题,引入预判的思想,提出了改进的资源优化分配算法,旨在保证承载多业务的下一代网络全网效应相对最优的基础上减少系统开销。仿真结果表明了方法的有效性。
It＇s an important way to guarantee QoS for the next generation network （NGN） with diverse services by allocating resources reasonably and optimizing the efficiency of whole network according to diverse service styles. A network resource allocating method based on co-operative game theory for NGN was proposed and analyzed, and it had a weakness which brought about overgreat system costing. In order to overcome this weakness, an idea about decision-making in advance was added, and an improved resource allocation algorithm was proposed, which could guarantee the efficiency of whole network best and reduce the system costing. Simulation results of this method show its validity.
