In optical burst switched (OBS) networks, burst loss is mainly due to contention that occurs at
both edge and core node. At edge node, contending burst may be electronically queued …

Burst cloning reduces burst loss at core nodes by sending multiple copies of the same burst
through optical burst switched (OBS) network simultaneously in order to enhance probability …

Optical Burst Switching (OBS) has become a mature technology to support the current and
next generation Internet over optical network backbones. In OBS networks contention is the …

In optical burst switched networks contention is the main source of burst loss. Burst
retransmission is a reactive loss recovery mechanism that attempts to resolve contention by …

A fundamental issue in optical burst switching (OBS) networks is to solve the burst
contention for the core node. In this paper, a novel priority-based contention solution …

Optical Burst Switched (OBS) networks are considered as promising candidates for the next
generation network architecture which does not need high-speed switch technologies. In …

In optical burst switched networks contention is the main source of burst loss. The burst
retransmission resolves contention by retransmitting the contended burst at the optical burst …

In this paper, we propose a novel proactive scheme, burst cloning, to reduce data loss due
to burst contention in optical burst-switched (OBS) networks. The idea is to replicate a burst …

We propose a preemptive scheme based on the hop number of a burst for optical burst
switching (OBS) networks. In the proposed scheme, when a burst fails in reserving a …

In this tutorial, we give an introduction to optical burst switching (OBS) networks and
compare different methods that have been given to improve performance of these networks …
