文中提出了有服务质量保证的虚拟链路的选取模型,服务网的虚拟链路的选择QoS因素主要包括虚拟链路的生存能力和虚拟链路的路由代价等因素,通过对服务网各参数的分析建立了P2P服务网络虚拟链路的选取模型,并给出了基于模拟退火的蚁群求解算法,最后通过实验分析了该算法的可行性和有效性.
We put forward a virtual link selection model of service quality assurance, and consider the quality of service metrics in this model includes viability, routing cost and so on. Through the analysis of these network parameters, we establish the virtual link selection model of P2P network and give the ant colony algorithm based on simulated annealing. At last, we analysis the feasibility and effectiveness of the algorithm through the experiment.
