In order to reasonably and quantitatively assess the performance of the traincommunicationnetwork under multi-factors and multi-services,this paper chooses the network time delay,bandwidth and packet loss rate as the indicators of network *** this paper,services in the traincommunicationnetwork have been divided into six classes according to their characteristics and *** paper proposes utilityfunctions model to describe the performance of each selected indicators under different services and then applies the model to evaluate the performance of each service and the traincommunication ***,using the measured data,it turns out that utilityfunctions can be effectively used to evaluate the quality of services and the performance of the network.
