BAIMD: A Responsive Rate Control for TCP over Optical Burst Switched (OBS) Networks
2006 IEEE International Conference on Communications, 2006Additive Increase Multiplicative Decrease (AIMD) window adjustment mechanism has been embedded in TCP in order to regulate the transmission rate in modern communication networks. In recent years, the AIMD (1,0.5) traffic regulation mechanism along with possibly additional enhancements, such as false timeout detection and explicit notification, has been

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.

Performance analysis of modified optical burst switching (OBS) ring network using dummy node
Optik, 2012Abstract In the present paper an analytical model of an optical burst switching ring network which is capable to handle the variable incoming traffic intelligently is presented. An efficient node architecture and network operating protocol enhances the data throughput in a congested network.

Impact of TCP synchronization on capacity dimensioning of Optical Burst Switched (OBS) links
2012 17th European Conference on Networks and Optical Communications, 2012We study the effect of TCP synchronization on Optical Burst Switched (OBS) networks and its impact on capacity dimensioning. The synchronization of TCP flows appears when a burst with segments from different TCP flows is discarded, making that all TCP flows reduce their transmission rate at the same time, leading to inefficient bandwidth sharing.

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.

Random contentions occur in optical burst-switched (OBS) networks because of one-way signaling and lack of optical buffers. These contentions can occur at low loads and are not necessarily an indication of congestion. The loss caused by them, however, causes TCP at the transport layer to reduce its send rate drastically, which is unnecessary and ...

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.

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.
