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 …

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 …

In OBS networks, burst loss affects negatively the performance of the higher layers.
Proactive loss recovery mechanisms, such as burst cloning, have the advantage of low burst …

We investigate the effects on performance of using a partial retransmission mechanism in
Optical Burst Switched (OBS) networks. In our scheme, the lost segments of a burst are …

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

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 …

Advances in enabling technologies and the explosive growth of Internet traffic has led to the
widespread proliferation of network systems in recent years. With their relatively low cost …

Optical burst switching (OBS) has been proposed as a competitive hybrid switching
technology to support the next generation optical Internet. However, due to their one-way …
