Abstract
This paper considers a scenario where the traffic of several LANs is transported on Deterministic Bit Rate (DBR) or Statistical Bit Rate (SBR) ATM Virtual Channel Connections (VCCs), that are then multiplexed into a DBR Virtual Path Connection (VPC) with fixed, dedicated bandwidth. It is investigated whether or not it is suitable to shape VCCs according to a DBR or SBR traffic contract before multiplexing. Results show that DBR shaping is rather useless, as with respect to the unshaped case no significant utilisation gain can be achieved without introducing high delays in the shapers’ buffers, and that SBR shaping behaves no better, due to the impossibility of finding a typical burst duration and mapping it on SBR traffic descriptors.
