“…Therefore, they cannot capture the influence of path-and network-related factors on segmentation performance, such as the increased segmentation probability due to the increased length of path and the quantity of traffic flow coming from other links, and the reduced load contention. 22 In this paper, we develop an analytical model to evaluate a path-correlated BS under the consideration of multipriority traffic arriving from other paths. 19, but its limitation, as shown in Ref.…”

Burst segmentation (BS) is a high-efficiency contention resolution scheme in bufferless optical burst switching (OBS) networks. A prioritized BS scheme for quality of service (QoS) support is developed. Unlike the existing work on the BS scheme, the proposed BS model considers path-correlated factors, such as path length, the adjoining paths carrying traffic on a given path, and the multipriority traffic coming from all paths. Byte loss probability for high-priority and low-priority bursts under the timebased assembly approach and the length-based assembly approach to estimate the performance of the proposed BS scheme by comparing the cumulative distribution function of a burst length in an OBS ingress node (source) with that in an egress node (destination) is introduced. A preemptive BS policy for different priority bursts is proposed to support the QoS of the OBS network. Finally, a simulation is given to validate the proposed analytical model in an existing OBS network with two priority bursts. It is shown that the proposed BS scheme can realize the service differentiation for multipriority traffic under the consideration of network topology-dependent parameters.

“…Optical burst switching is envisioned as the technology that will support growing future bandwidth needs efficiently, as in many ways it combines the merits of OCS and OPS while overcoming their shortcomings [2,3]. However, with the prevalence of triple-play services (i.e., data, voice, and video) and web-based multimedia applications, Quality of Service (QoS) differentiation has become a crucial issue for future OBS networks intended for practical deployment [4][5][6].…”

A novel ingress node design for video streaming over optical burst switching networks

This paper introduces a novel ingress node design which takes advantage of video data partitioning in order to deliver enhanced video streaming quality when using H.264/AVC codec over optical burst switching networks. Ns2 simulations show that the proposed scheme delivers improved video traffic quality without affecting other traffic, such as best effort traffic. Although the extra network load is comparatively small, the average gain in video PSNR was 5 dB over existing burst cloning schemes, with a maximum end-to-end delay of 17 ms, and jitter of less than 0.35 ms.
