Delay performance of a leaky bucket regulated multiplexer based on burstiness characterization

In high-speed networks, a congestion control strategy has to manage bandwidth allocation according to the characteristics of the input sources. The definition of traffic characterization is significant in all aspects concerning network performance. Using the burstiness characterization based on a virtual queue principle, we analyze the delay performance of a leaky bucket regulated multiplexer, and investigate the effectiveness of a leaky bucket in protecting a delay bound of a multiplexer system. Numerical results show that a leaky bucket can provide a well-behaved traffic stream with guaranteed delay bound in the presence of a misbehaving traffic stream.
