QoS scheme with burst dropping in optical burst switching

2003 IEEE Pacific Rim Conference on Communications Computers and Signal Processing (PACRIM 2003) (Cat. No.03CH37490), 2004
We propose a new QoS control scheme by using burst dropping in optical burst switched network. Our proposed scheme consists of burst dropping (BD) technique at core nodes and packet arrangement technique at edge nodes. BD technique has been proposed as the effective solution that can improve packet loss at intermediate nodes. By using BD technique, the

First demonstration of real-time all-optical software-defined intra-data center star network using OFDM and burst switching

2013 18th OptoElectronics and Communications Conference held jointly with 2013 International Conference on Photonics in Switching (OECC/PS), 2013
We demonstrate the first real-time high-capacity star OFDM-based all-optical intra-data center network using burst switching and OpenFlow-based software-defined networking.

Periodically scheduled burst flows in optical burst switching networks

International Journal of Communication Networks and Distributed Systems, 2007
Providing flexible quality of service (QoS) for multiple classes of traffic is one of the important challenges in the design of optical burst switching (OBS) networks. In this paper, we propose a novel bandwidth reservation scheme for periodically scheduled bursts.

A burst assembly algorithm in optical burst switching networks

Optical Fiber Communication Conference and Exhibit, 2002
The proposed algorithm changes the data burst size adaptively in accordance with the offered load and offers high average data burst utilization with less timer operation. It also offers high average data burst utilization as burstiness increases which reduces the probability of continuous blocking problem in the bandwidth reservation request. Finally,

EDFA transient suppression in optical burst switching systems

International Conference on Transparent Optical Networks, 2012
Authors demonstrate that a combination of feed-back control, feed-forward control, optical delay line and saturating channel can obtain the effective suppression of the transient effect in EDFA-based optical burst switched systems.

Optical Burst Switching

2005
The concept of burst switching was proposed initially in the context of voice communications by Haselton (1983) and Amstutz (1983; 1989) in the early 1980s. More recently, in the late 1990s, optical burst switching (OBS) was proposed as a new switching paradigm for the so-called optical Internet in order to overcome the technical limitations of optical

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.

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 ...

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.

Investigations on burst length in optical burst switched networks

Optik, 2010
In this paper, we investigate the performance of optical burst switched networks for erbium-doped fiber amplifiers (EDFAs) and semiconductor optical amplifiers (SOAs). We show that EDFAs are more suitable for burst switching as compared to SOAs. We further investigate the burst length for 18, 24.6 and 55 km optical switched network. It is observed that
