An allocation algorithm for transporting compressed video

In this paper, we proposed a novel weight-based bandwidth allocation algorithm (WBA) for transporting compressed video traffic using feedback. Extensive simulation using a modified NIST simulator is conducted to evaluate its performance under a general weight-based share policy. Our results demonstrate that the WBA algorithm is capable of allocating bandwidth fairly for the minimum cell rate (MCR) plus weighted allocation fairness criteria among competitive compressed video sources, and is capable of reallocating smoothly when there are renegotiations of the minimum guaranteed cell rate and weight by some connections. We also show that WBA algorithm is flexible for the reallocation when a new connection is admitted. Furthermore, when unutilized network bandwidth becomes available, our algorithm is capable of exploiting it to dynamically allocate unused bandwidth
