研究了下一代网络中瓶颈链路的带宽资源分配问题,利用融入了社会距离参数的用户效用函数,使得用户的带宽资源分配问题转变成一个在不等式约束条件下的最优化问题.由于最优化问题的复杂性,最优的分配带宽是用数值方法估计的,相关的结果证明了社会距离参数在带宽分配上的重要影响.利用社会距离值对实际网络拓扑中节点进行分类聚合,证明了各组间的最优化带宽分配与网络拓扑中节点数目及分组中节点数目门限值存在相互影响的关系,算法有利于更好地对网络带宽资源进行分配.
The problem of bandwidth resource allocation of bottleneck link in next generation network is studied, and the user utility function which incorporates social distance parameter is used to change user’s bandwidth resource allocation problem into an optimization problem under inequality constraint. Since optimization problem The optimal allocation bandwidth is estimated numerically and the correlation result proves the important influence of the social distance parameter on the bandwidth allocation.Using the social distance value to classify the nodes in the actual network topology, it is proved that each group The optimal bandwidth allocation between the network topology and the number of nodes in the network topology and the number of nodes in the packet affect each other. The algorithm helps to better allocate network bandwidth resources.
