Optical Hybrid Switching – Combined Optical Burst Switching and Optical Circuit Switching

2004
In this paper, we propose a new optical hybrid switching technique which combined Optical Burst Switching (OBS) and Optical Circuit Switching (OCS) using flow classification. In particular, this switching technique classifies incoming IP traffic flows into short-lived and long-lived flows for Quality of Service (QoS) provisioning according to traffic ...

Maximizing throughput for optical burst switching networks

IEEE INFOCOM 2004, 2004
In optical burst switching (OBS) networks, a key problem is to schedule as many bursts as possible on wavelength channels so that the throughput is maximized and the burst loss is minimized. Most of the current research on OBS has been concentrated on reducing burst loss in an ldquoaverage-caserdquo sense, and little effort has been devoted to ...

Buffering-deflection tradeoffs in optical burst switching

Photonic Network Communications, 2010
A very important issue in optical burst switching (OBS) networks is the excessive burst drop when no suitable network resources are found during path reservation. In this study, a network scenario is evaluated in which AWG-based optical nodes are used as burst router nodes within the optical network.

Burst circulating threat in optical burst switched networks

2014 IEEE International Conference on Advanced Communications, Control and Computing Technologies, 2014
Optical network is a high speed network thus reduce the huge bandwidth demands and increase the internet users. Optical burst switched network is an optical networking technique that allows dynamic sub wavelength. OBS is viewed as compromise the optical packet switching and optical circuit switching networks.

Burst dropping policies in optical burst switched network

Optik, 2010
Optical burst switching (OBS) has been proposed as a competitive switching technology to support the next generation optical Internet. However, due to their one-way resource reservation mechanism, OBS networks experience high bursts (thus packets) loss rate.

Data burst grooming in optical burst-switched networks

2nd International Conference on Broadband Networks, 2005., 2005
In this paper we address the problem of data burst grooming in optical burst-switched (OBS) networks. In OBS networks IP packets with the same edge node destination are assembled into larger packets called data bursts. Depending on the core node's switching technology, data bursts are required to have a minimum length. On the other hand, each IP packet

Optical-code-based optical burst switching networks

SPIE Proceedings, 2005
One of the major bottlenecks in conventional OBS networks is the processing delay of the control packet at each node. This is due to slow electronics of the node processors. In this paper, first we describe our proposed protocols of ultrafast optical path setup using an OC-labeled control packet.

Trends in optical burst switching

SPIE Proceedings, 2003
Optical burst switching (OBS) has been proposed in the late 1990s as a novel photonic network architecture directed towards efficient transport of IP traffic. OBS aims at cost-efficient and dynamic provisioning of sub-wavelength granularity by optimally combining electronics and optics. Optical bursts cut through intermediate nodes, i.e., data stays in

Introduction to Optical Burst Switching

2009
The ever-increasing demand for higher bandwidth due to the growth of bandwidth-intensive applications such as remote information access, video-on-demand, video conferencing, online trading, and other multimedia applications motivated the search for alternatives to traditional electronic networks.
