Video on Demand over ATM: System Design and Networking Requirements
نویسنده
چکیده
In recent years there has been a strong interest in transmitting compressed Video over ATM. Previous work has dealt with transmitting MPEG over CBR and VBR services of ATM. The ABR service of ATM is expected to be much more cost eeective than CBR or VBR. There has been a limited amount of work done in transmitting video over ABR. However, there hasn't been much work done on running client/server applications (for example, video on demand) over ABR. In this paper, we propose models for the design of video on demand systems transmitting MPEG-2 video over an ATM network using the ABR service category. By using the Real Time Dynamic Equilation (RTDE) analysis, we proposed models to determine buuering requirements at the client and the server of the system. We have also developed an analytical method to determine the ABR eld parameters (such as PCR and ACR) required to run interactive client/server multi-media applications over an ATM network using the ABR service.
