Is VBR a solution for an ATM LAN ?
Olivier Bonaventure, Espen Klovning, André A. S. Danthine · 1997
We present and discuss detailed measurements showing how TCP behaves in an ATM LAN where a Variable Bit Rate (VBR) traffic contract is enforced by a Usage Parameter Control (UPC) mechanism. These measurements show that TCP has a lot of difficulties to adapt its behaviour to such a traffic contract. In our environment, TCP only achieved a 10% utilisation of a 10 Mbps VBR VC. We then discuss and evaluate possible solutions to improve this low utilisation of the reserved bandwidth. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
