Contention Resolution in Optical Burst Switching(OBS)Network : A Time Domain Approach
International Conference on Fibre Optics and Photonics, 2012An analytical model is developed to evaluate burst loss probability in optical-burst switching(OBS) network by considering the regimes of short and long FDLs. The impact of different node non-idealities on network performance is also estimated.

Manycast Service in Optical Burst/Packet Switched (OBS/OPS) Networks (Invited Paper)
2009Recently there is an emergence of many Internet applications such as distributed interactive simulations (DIS), and high-performance scientific computations such Grid computing. These applications require huge amount of bandwidth and a viable communication paradigm to coordinate with multiple sources and destinations.

Coordinated Multi-Layer Loss Recovery in TCP over Optical Burst-Switched (OBS) Networks
2010 IEEE International Conference on Communications, 2010It is well-known that the bufferless nature of OBS networks causes random burst loss even at low traffic loads. When TCP is used over OBS, these random losses make the TCP sender decrease its congestion window even though the network may not be congested. This results in significant TCP throughput degradation.

Analysis of timing parameters in wavelength-routed optical burst-switched (WR-OBS) networks
IEEE/LEOS Summer Topi All-Optical Networking: Existing and Emerging Architecture and Applications/Dynamic Enablers of Next-Generation Optical Communications Systems/Fast Optical Processing in Optical Transmission/VCSEL and Microcavity Lasers., 2003The relationship between timing parameters in a WR-OBS network architecture is analyzed with respect to packet loss, delay constraints, and network scalability. A novel burst-aggregation scheme provides low latencies even for high traffic loads.

Analytical model for optical burst switching (OBS) networks with linear transmission impairments
Second IFIP International Conference on Wireless and Optical Communications Networks, 2005. WOCN 2005., 2005In this paper we study the effect of the physical impairments on the performance of the OBS network. More specifically we focus on the amplifier related noise (ASE) and the polarization mode dispersion (PMD) and their effects in terms of the blocking probability of the network.

OFC/NFOEC Technical Digest. Optical Fiber Communication Conference, 2005., 2005
We develop dynamic routing mechanisms for preplanned congestion avoidance in OBS networks. Based on our routing mechanisms, we propose a new protection approach against failures which significantly improves network throughput and survivability.

The generalized optical burst switching (G-OBS) enabling multi-service converging transport
Digest of the 9th International Conference on Optical Internet (COIN 2010), 2010How to shrink the gap between the service provision capacity and the QoS requirements of user applications is one of key issues of the naive OBS in multi-service carry environment. This paper extended the concept of optical burst, and proposed a novel OBS architecture (i.e., G-OBS).

Effective Resource Utilization and QoS Oriented Integrated Scheme for Optical Burst Switching (OBS)
Journal of Optical Communications, 2010Optical burst switching (OBS) is a switching technique that occupies the middle of the spectrum between the well-known circuit switching and packet switching paradigms. OBS has advantages in terms of switching efficiency for bursty IP traffic and optical hardware feasibility.

Maximize the utilization of WDM channels using WR-OBS in adaptive optical burst switching
IET Chennai Fourth International Conference on Sustainable Energy and Intelligent Systems (SEISCON 2013), 2013Optical Burst Switching (OBS) adapts to the size of switching data unit of the network load. It is a two-way reservation scheme. IP is collected at the egress node. Every active source-destination pair tries to reserve a light path and for every successful reservation, it transmits an optical burst whose size is proportional to the number of active ...
