A computational framework for determining the data loss rate for three basic types of burst assembly algorithms of optical burst switched(OBS) network is proposed here. The model is based on our previous work, where a computational scheme for capturing the effect of time correlation of input IP-packet sources on characteristics of assembled burst under various burst assembly algorithms, has been developed...
We develop a computational framework to study the impact of burst assembly algorithms on the byte loss rate (ByLR) of an OBS network under bursty (ON-OFF) IP traffic input. First we propose a computational method to analyze the characteristics of assembled bursts in terms of burst length and/or burst assembly time distribution under timer-based, burst-threshold-based, and dual-threshold-based burst...
In this paper, we propose a proactive burst assembly scheme for optical burst switching network where bursts are created in such a way that it suffers minimum loss at the immediate outgoing link. The future reservation states of individual wavelength channels are used to construct and update the availability state of the whole link as a function of time. The assembly algorithm, before assembling a...
In this paper, an exact analytical model for computation of burst length distribution under time-correlated input sources, at the output of an edge optical burst switching node, has been developed. Approximation techniques, to reduce time complexity of the model, have also been suggested. Effects of time correlation is successfully captured and it is found that for constant load, the variance of burst...
