Applying generalized aimd to optical burst switched networks

Abstract

Many new network applications require a stable, transparent, well-defined and understood communications network. In this paper, we first consider and analyze the simple arrangement of adding caching nodes at the edge of the an Optical Burst Switched (OBS). The caching scheme is then used to make the case for the addition of congestion control to OBS networks using General AIMD to manage the throughput at the network's core nodes. It was found that loss could be reduced in the core by almost 72% by applying General AIMD congestion control to the OBS network with a congestion threshold, while keeping end-to-end delay within 5% of traditional OBS implementations.
