The impacts of burst assembly on the traffic properties in optical burst switching networks

International Conference on Communication Technology Proceedings, 2003. ICCT 2003., 2004
Optical burst switching (OBS) is regarded as one of the most promising solutions for the next generation backbone. Burst assembly in the edge nodes is an important issue to be addressed in OBS networks. In this paper, the impacts of burst assembly using different schemes on the Poisson traffic properties are investigated and simulated.

Virtual Burst Assembly - A Solution to Out-of-Sequence Delivery in Optical Burst Switching Networks

IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008
Optical burst switching (OBS) has been considered the most promising optical switching technology. To the best of authors' knowledge, this is the first paper that identifies the out- of-sequence delivery problem in OBS networks. To minimize the impact of the out-of-sequence delivery on buffer space and resequencing latency, we propose a novel virtual ...

Provision of differentiated performance in Optical Burst Switching networks based on burst assembly processes

Computer Communications, 2007
Optical Burst Switching (OBS) has been designed as a practical solution for the high-speed transport network using enabling optical technologies, which can work without optical buffering or pure optical signal processing in the intermediate nodes.

TCP window estimation for burst assembly in OBS networks

The IEEE symposium on Computers and Communications, 2010
In this paper TCP performance over Optical Burst Switching networks is investigated by considering the burst assembly function implemented in the edge nodes. This function has a very important role on end-to-end performance and a edge node architecture is here proposed for improving performance.

Analyzing the effects of burst assembly in optical burst switching under self-similar traffic

Advanced Industrial Conference on Telecommunications/Service Assurance with Partial and Intermittent Resources Conference/E-Learning on Telecommunications Workshop (AICT/SAPIR/ELETE'05), 2005
Optical burst switching is a novel switching concept which is a hybrid of optical packet switching and optical wavelength routing. In order to provide an efficient bandwidth utilization, various burst assembly and scheduling schemes for optical bursts are introduced.

A new framework and burst assembly for IP DiffServ over optical burst switching networks

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
IP differentiated services (DiffServ) has been standardized by the IETF and is considered as a promising IP QoS solution due to its scalability and ease of implementation. In this paper, we present a novel framework for IP differentiated services (DiffServ) over optical burst switching (OBS), namely, DS-OBS.

Traffic Analysis and Traffic-Smoothing Burst Assembly Methods for the Optical Burst Switching Network

IEICE Transactions on Communications, 2007
Burst assembly at edge nodes is an important issue for the Optical Burst Switching (OBS) networks because it has a great impact on the traffic characteristics. We analyze the assembled traffic of the Science Information Network (SINET) by using the Fractional Brownian Motion (FBM) model. The analytical and simulation results show that existing assembly

Adaptive Threshold based Burst Assembly in OBS Networks

2006 Canadian Conference on Electrical and Computer Engineering, 2006
In this work a congestion level based optical burst assembly technique is proposed to be used in optical burst switching (OBS) networks. The effect of adaptive burstification duration (time threshold) and adaptive size threshold on the performance of OBS channel scheduling is analyzed under various traffic types.

Research Paper on Burst Assembly Modeling for Optical Burst Switched Network

2014 Fourth International Conference on Communication Systems and Network Technologies, 2014
Optical burst formation is aggregation of incoming packets for same destination, which are switched together. Optical Burst Switch (OBS) allow variable burst formation time and burst sizes which can be so that network resources will be used optimally.

Round-robin burst assembly and constant transmission scheduling for optical burst switching networks

GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 2004
In this paper, we propose a round-robin burst assembly and constant burst transmission for optical burst switching (OBS) network. In the proposed method, ingress edge node has multiple buffers where IP packets are stored depending on their egress edge nodes, and bursts are assembled at the buffers in round-robin manner. Moreover, bursts are transmitted
