“…The strategies also assume two different approaches, first considers the final path which is chosen from a set of K different eligible paths previously calculated and in second one, the final path is entirely determined by the algorithm. Charbonneau et al (2012) have proposed Forward Segment Redundancy (FSR), a proactive technique to prevent data loss during random contentions in the optical core. With FSR, redundant TCP segments are appended to each burst at the edge and Redundant Burst Segmentation (RBS) is implemented in the core so that when a contention occurs, primarily redundant data is dropped.…”

The Optical Burst Switching is a new switching technology that efficiently utilizes the bandwidth in the optical layer. The key areas to be concentrated in Optical Burst Switching (OBS) networks are the burst assembly and burst scheduling i.e., assignment of wavelengths to the incoming bursts. This study presents a New Burst Assembly and Scheduling (NBAS) technique in a simultaneous multipath transmission for burst loss recovery in OBS networks. A Redundant Burst Segmentation (RBS) is used for the burst assembly. In our proposed algorithm, the proper policy is selected based on the priority of each burst, the length of each burst and the length of the redundant data. After assembling the burst, the burst scheduler algorithm schedules the burst. This algorithm is responsible for the output wavelength and contention-free fiber delay lines to switch every burst payload to its target output fiber. The OBS network simulator (nOBS) patch in NS-2 is used to simulate our network. NBAS technique improves the quality of service constraints like delivery ratio, delay compared to RBS technique. From the simulation results, it is shown that our proposed technique New Burst Assembly and Scheduling (NBAS) optimizes the delay and overhead through the best burst assembly and scheduling thereby increasing the delivery ratio

“…In simulation, an exponential traffic model is used to generate bursty traffic in which 5 traffic flows are setup between two edge routers. In all the simulation environments, we compare the results of the proposed NBAS technique with Redundant Burst Segmentation (RBS) technique (Charbonneau et al, 2012).…”

Optical Burst Switching (OBS) is perceived as the most favorable switching method for the next generation all optical networks to support the growth of the number of Internet users and to satisfy bandwidth demands for greedy-bandwidth applications which are in continuous growth. OBS consists of an edge node and a core node. The edge node is responsible for burst assembly which is the first process in an OBS network. Currently, there is only one review paper for burst assembly; the paper is limited in number of techniques reviewed. In this paper, we have undertaken a comprehensive review of burst assembly techniques proposed for OBS where techniques are reviewed by category. The aim is to identify strengths and weaknesses of these techniques. The analysis of the paper will assist researchers in finding problems; thus, a significant amount of time will be saved which can be used in developing appropriate solutions for OBS networks.
