Abstract:

This paper presents a finite state resource management scheme, so called R++, for dynamically allocating bandwidth for variable bit-rate(VBR)traffic in a network or component of the network that supports resource renegotiations (e.g. ATM,RSVP etc.). The introduced scheme does not assume any a-priori knowledge of traffic, and it uses multiple bandwidth decision units in a hierarchy to eliminate large fluctuations in allocated bandwidth. The performance is evaluated on different MPEG-1 coded traces. Simulation experiments show that the new approach achieves better link utilization and lower 0.99-quantile queue sizes after less number of renegotiations than other methods in the literature.
