A Reliable, Adaptive Network Protocol for Video Transport

In thispaper, we present anadaptive networklayer protocol for VBR video transport. It: (1) minimizes buffer requirement in the network whileguaranteeingthat packets of VBR encoded video flows will not be lost, and (2) minimizes endto-end delay and jitter of frames. To achieve the former objective, we utilize receiver-oriented adaptive credit-based flow control algorithm, and derive necessary and sufficient number of buffers that should be reserved for ensuring its reliability. To minimize the end-to-end delay and jitter for VBR encoded video streams, we: (1) present bandwidthestimationtechniques which exploit the structure of the video traffic, and (2) define a new fairness criteria for buffer allocation and then present a fair buffer/bandwidth allocation algorithm. We experimentally evaluate this protocol for a wide range of parameters and many network configuration and demonstrate its adaptability. We also compare the performance of the protocol with numerous other schemes and demon...
