A Joint Design of Congestion Control and Burst Contention Resolution for Optical Burst Switching Networks Citation
This paper revisits burst contention resolution problems in optical burst switching (OBS) networks from the viewpoint of network utility maximization. Burst collision occurs when two or more bursts access the same wavelength simultaneously, and the occurrence becomes more frequent as the offered load increases. In particular, when the network is overloaded, no contention resolution scheme would...
متن کاملLook-ahead Window Contention Resolution in Optical Burst Switched Networks
In this article we introduce a new contention resolution algorithm called Look-ahead Window Contention Resolution (LCR). This unique contention resolution approach can be used in conjunction with a scheduling technique to reduce the packet loss in an optical burst switched network. We analyze the performance of LCR by means of simulations and compare it with other major existing contention reso...
متن کاملPractical Priority Contention Resolution for Slotted Optical Burst Switching Networks
Optical burst switching (OBS) has been proposed as a competitive hybrid switching technology to support the nextgeneration optical Internet. This paper addresses performance issues in the slotted and unslotted OBS networks and extends a proposed contention resolution algorithm called the Shortest Drop Policy to support service differentiation. In addition, this paper presents a practical schedu...
متن کاملThe Adaptive Contention Resolution Mechanism for Optical Burst Switched Network
In Optical Burst Switched (OBS) Networks, data is transported in buffer less network and hence there is fair amount of chances of contention among the bursts. Many Burst retransmission schemes have been proposed in the literature to deal with bus contention. Burst retransmission gives better throughput performance for higher layers. The random retransmission mechanism often leads to unprecedent...
