Hybrid wireless optical broadband access networks are the future of internet service providers. Due to high capacity and flexibility, they are the most promising architecture for last mile internet access. Addressing the fact that deployed radios in the wireless part of WOBAN are under-utilized in current routing algorithms, half of the links remain idle while few of these links are carrying traffic,...
Several switching architectures like circuit switching, packet switching and burst switching have been proposed and developed for efficient utilization of high speed optical networks. Among these Dynamic Optical Circuit Switching (DOCS) has been found to be more useful for provisioning requests in backbone (core) networks due to its capability to provide huge bandwidth by establishing high capacity...
To meet the demands of ever increasing bandwidth hungry applications architectures like circuit switching, packet switching and burst switching have been proposed in the literature. Dynamic Optical Circuit Switching (DOCS) is the optical counter part of the circuit switching; it can provide huge bandwidth to the end users by establishing high capacity light-paths. For provisioning requests in DOCS...
Advance reservation is a technique employed so that a request is guaranteed 100% availability of the resource it applied for sometimes earlier. In this paper we introduce the concept of advance reservation of lightpaths for a certain request characterized by some source and multiple destinations and also the time when network resources are demanded. We first present a point to multipoint adaptive...
One of the issues in Optical Burst Switching (OBS) scheme is that it does not ensure safe and lossless transmission. There is always a probability of burst loss associated with this phenomenon. To solve this problem a new scheme, bimodal burst switching was proposed which ensures a zero burst loss probability. In order to support different types of prioritized traffic over the same network, Quality...
Many emerging high performance applications require distributed infrastructure that is significantly more powerful and flexible than traditional grids. Such applications require the optimization, close integration, and control of all grid resources, including networks. The EnLIGHTened (ENL) computing project has designed an architectural framework that allows grid applications to dynamically request...
