Because of the best-effort characteristics of the Internet, it is important to suppress the degradation of communication quality on the receiving side caused by data packet loss and errors as well as the limited network bandwidth. This paper focus on MPEG transmission over the Internet and Differentiated Services architecture established to improve Quality of Services (QoS). Packets are classified using a frame-based scheme in the mechanism so as to discard the unimportant packets marked at the edge router and insure the packets with higher-priority sent from core router to destination host first. The simulation results and mathematical analysis demonstrate that the proposed mechanism achieves better quality of media streaming compared with the current best-effort Internet, in terms of playable frame rate and real-time performance at the receiving side.
