采用福利经济学的分析方法,提出网络资源分配的生产消费模型,通过引入效用可能性边界和社会福利函数,得到资源分配问题的优化目标,指出当社会福利函数取得最大值时,网络系统性能取得效率和公平意义上的最优.通过对资源集和资源约束、用户集和服务需求进行数学抽象,将资源分配的概念模型转化为一个多约束优化模型NRAP.相对于Kelly无差别速率分配模型,本模型可以较完整地刻画网络传输服务的生产和消费特性,且能够反映用户在服务质量上的不同要求.分析说明了NRAP资源分配模型在实际网络中的应用及算法的实现机制.
By using the analysis method of welfare economics, this paper puts forward the production and consumption model of network resource allocation. By introducing the boundary of utility possibility and social welfare function, the optimization goal of resource allocation problem is obtained. When the social welfare function gets the maximum value, Efficiency and fairness.According to mathematical abstraction of resource set, resource set, user set and service demand, the conceptual model of resource allocation is transformed into a multi-constrained optimization model NRAP.Compared with the Kelly undifferentiated rate assignment model, This model can characterize the production and consumption characteristics of network transmission service more completely, and can reflect the different requirements of users in service quality.The paper analyzes the application of NRAP resource allocation model in real network and the realization mechanism of the algorithm.
