“…TB mechanism has been employed to characterize the traffic generated by MPEG video in [4,6,8]. In [4], Alam et al study the effects of a traffic shaper at the video source on the transmission characteristics of MPEG video streams while providing delay and bandwidth guarantees. In [6], Lombaedo et al have applied the TB model to evaluate the probability of marking nonconforming data packets for the transmission of MPEG video on the Internet.…”

We present a dynamic modelfor access control mechanism used in computer communication network applied to MPEG video transmission over Internet. This modelis different fromthosedeveloped inthe previous works related to this topic. In our model, token buckets supported by data buffersare used to shape incoming traffic and one multiplexor, serving all the token pools, multiplexes all theconforming traffic. The model is governed by a system of discrete nonlinear difference equations. Weuse neural network as the feedback controller which receives at its input (measurable) available information and provides at its output the optimal control. The simulated annealing algorithm isusedto optimize the system performance by adjusting the weights. For illustration, we presentnumerical results which show that the system performance of MPEG video server can be improved by using neural network and simulated annealing approach.

“…However, recent efforts, such as Integrated and Differentiated Service at the IETF, are underway to incorporate service guarantees in TCP/IP based networks. As a result, there has been some preliminary work on transporting video over the Integrated Service [1,2]. In contrast to legacy data networks, the Asynchronous Transfer Mode (ATM) network has been designed to support both real and non-real time applications making it very suitable for transporting multimedia.…”

Multimedia is an emerging service which integrates voice, video and data in the same service. With the progress made in high speed large capacity multimedia servers, high speed networks, QoS, service guarantees and set top boxes, it is currently possible to cost effectively and efficiently carry multimedia over high speed networks. This paper surveys the progress made, and the future of efficiently carrying multimedia over the emerging Asynchronous Transfer Mode networks. q

“…Since the token bucket algorithm (with peak rate control) has been specified as the traffic policing mechanism in the GS [1], a token bucket (followed by a leaky bucket for peak rate control) can be used also at the source to shape the traffic [18] so that the traffic profile is conformant to the negotiated traffic specification. Although it is possible to adopt a traffic shaping algorithm [19] which ensures that the transmitted traffic is conformant to a token bucket traffic policing element in the network, the token bucket itself can also be used at the source to shape MPEG video traffic.…”

The Internet Engineering Task Force (IETF) has proposed the Guaranteed Service (GS) in the Integrated Services model with firm delay and bandwidth guarantees. In this paper, we study the effects of a token bucket traffic shaper at the source on the transmission characteristics of Motion Picture Experts Group (MPEG) compressed video streams over the GS. We develop an analytical model of the traffic shaper, and also carry out numerical simulation of the transmission performance using MPEG trace data from several different video sequences. The analytical model and the numerical simulation results are in excellent agreement. Our study provides a technique to determine the token bucket parameters that have to be specified while setting up a GS flow. Our study reveals that the traffic shaping process gives an end application a wide range of flexibility in controlling the delay. By choosing appropriate token bucket traffic shaper parameters, delay can be reduced significantly without the need to reserve costly network resources for less delay-sensitive applications, while time-critical applications may specify the required token bucket parameters for minimum delay. ᭧
