This paper analyzes the performance of an optical packet switch architecture with highly distributed control, designed for interconnection of cluster switches in a simulated data center traffic environment. The system under development can be scaled up to a very large ports count, in the thousand order, enabling interconnection of a great number of servers. An important feature of this optical packet...
We study the design of virtual optical bus (VOB) network, which has been recently proposed as a packet-oriented all-optical solution for transport networks. Design of a VOB network consists of grouping all edge-to-edge flows in the network into clusters called VOBs and that has to be done with the objective of minimizing packet collision rate in the optical network. We present an efficient heuristic...
Today, experimentally driven research is central to future Internet research and innovation. A major challenge for this type of research is providing a mechanism for efficient sharing of the experimental infrastructure among several research experiments while ensuring experiments are run in complete separation without interfering with each other. This paper address these issues by proposing a cross-layer...
This study adapts the two conventional protection methods, 1+1 and 1∶1, to an all-optical, time-slotted packet ring designed for metropolitan area networks. The two corresponding protection schemes, Premium and Regular, rely on OAM messages that can be carried in each time slot. Each scheme offers packet level protection and maintains a congestion free and simple recovery mechanism in case of single...
