Agile Bandwidth Management Techniques in Slotted All-Optical Packet Switched Networks

The next generation metro network is most likely to be based on high-capacity agile all-optical networks. The authors consider a metro network architecture that consists of a number of buffer-less all-optical core switches, where a number of edge switches are connected to each core switch in an overlaid star topology. They would like to design potential candidates of resource-sharing schemes in such a network and evaluate their performances, where they guarantee to deliver optical packets to their destinations. The first scheme is reservation-based, in which decisions are made at each core switch so that collisions (and therefore loss) can be avoided through reservations.
