Abstract: There are strict limits to the traffic of end-system in DiffServ network.To assure applications with different requests in end-system to get reasonable resources,an end-system traffic shaping algorithm based on resource management is presented.The algorithm gives a scheduling and shaping method to flow in end-system according to its application’s resource request.Analysis and test results show that the algorithm can not only limit the traffic of end-system to DS,but also assure the resource request of each application,and have the better performance.
