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.

Multi-granular Stream Optical Burst Switching

2006 3rd International Conference on Broadband Communications, Networks and Systems, 2006
This paper presents a novel architecture of multi-granular stream optical burst switching (MGS-OBS), which enables an all-optical network to support sub-wavelength streaming traffic of diverse bandwidth granularities with guaranteed end-to-end delay and data loss rate.

Evaluation of burst retransmission in optical burst-switched networks

2nd International Conference on Broadband Networks, 2005., 2005
In this paper, we evaluate the performance of a burst retransmission scheme in which the bursts lost due to contentions in an OBS network are retransmitted at the OBS layer. The retransmission scheme aims to reduce burst loss probability in OBS networks.

Performance enhancement of optical burst switching using burst segmentation

IEEE International Conference on Communications, 2003. ICC '03., 2004
In this paper we provide an analytical framework for studying the performance of Optical Burst Switching (OBS) networks using Burst Segmentation. We first consider a single link model to evaluate the blocking probability of OBS using Burst Segmentation and confirm it by simulation.
