- Guaranteeing end-to-end QoS for multimedia traffic in the IP transport network is a challenging issue. Monitoring the one way delay of the multimedia traffic is necessary but no clear solution for the performance monitoring in the core network exists. In the previous work [1], we introduced an one-way delay monitoring mechanism called DiffProbe. We introduced the basic concept and the implementation details in the MPLS core network. In this paper, we provided an analytical model of the scheme and investigated the performance of the proposed delay measurement mechanism. We evaluate the accuracy of the delay measurement mechanism and the efficiency of the control mechanism with the simulation. The numerical result shows that our proposed algorithm captures the delay performance of the real traffic when the traffic load is high. © 2007 IEEE.
