A policing algorithm for MPEG streams on ATM networks
Wen-Tsuen Chen, Wu-Sheng Huang, Cheng-Ho Lin · 2002
Video traffic is expected to account for a significant share of the total traffic volume in future ATM networks. In order to guarantee quality of service, it is important to police and manage the video traffic streams. MPEG, including I-Frame, P-Frame, and B-Frame, is the well accepted standard for video compression. Among these three kinds of frames, I-Frame and P-Frame are critical for video decoding. In this paper, we propose an algorithm to increase the surviving probability of I-Frame and P-Frame, strengthen the functionality of traffic policing, and achieve fairness furthermore. Based on the punish concept, it also establishes a cooperative environment for multiple video streams to share the network bandwidth.
