With the constantly increasing multimedia real time applications, such as video conferencing and distributed games, which are bandwidth-intensive applications, all-optical multiple delivery has become increasingly important in order to enhance multicast applications' performance. This technique consists in delivering an optical signal from a source edge router to multiple destinations without going...
In this paper, we investigate the design and the implementation of dynamic optical bursts grooming in segmented-based traffic OBS networks. The objective is to aggregate into one burst, different overlapping short bursts which are transmitted to the same destination. This process is executed at the grooming unit of the core node. We propose a design and a physical implementation of this unit based...
In this paper, we present a scheme for dynamic resource management using traffic descriptors. A priority multi-class scheme to support QoS on an optical network is defined. Unlike existing mechanisms that depend on buffers management and scheduling algorithms, our mechanism does not require any electronic buffering in the intermediate optical network nodes, which is greatly desired. The proposed scheme...
