Abstract
One of the most interesting improvements of the Internet today is the provisioning of services for interactive audio--visual applications. Such applications have quality requirements which place limits on both transfer delays and information losses. Our goal is to support interactive video with only small modifications to network routers and control systems. The approach we favor is to ensure the quality for a session by forward--error correction. The code strength is dynamically tuned to meet a user's quality expectation, given the experienced loss process of the transfer. To make the tuning feasible, the network state must be predictable. We accomplish this by regulation of the load through sender--based admission control. It uses end--to--end probes of the network state and a self--imposed blocking if then sender determines that a sensible transfer cannot be made. The paper outlines this procedure along with a review of source coding considerations and a description of tunable error...
