Analyses, simulations, and experiments on the performance of the token-based optical burst transport ring networks

Abstract

In this paper, both numerical and simulated modeling techniques were applied to analyze the influence on the performance of the token-based Optical Burst Transport (OBT) ring networks caused by the parameters, such as the minimum and maximum burst length, the circumference of the ring, and so on. We first analyze the issue by numerical analysis in the case that each node has only one token. After that, we confirm the analytical results and made further researches in the case that each node has multiple tokens by simulated analysis. All the results show that to design a high-performance token-based OBT ring network, not only the common parameters, such as the number of nodes and wavelengths, and the circumference of the ring, but also the special parameters, such as the minimum and maximum burst length, and the offset time should be taken into account. Furthermore, a testbed of Three-node Token-based OBT ring network Using Fixed Transmitter and Tuneable Receiver (FTTR) is constructed. With it, the variations of the network performance caused by the maximum burst length are investigated. 1
