Abstract
This chapter describes the embedding properties of some emerging reconfigurable and partitionable optical networks, and motivates and formalizes several combinatorial optimization problems associated with embeddings in these networks. In particular, the embedding properties of a reconfigurable multichannel free-space optical backplane called the “HyperPlane” will be described. The networks to be embedded can be conventional point-to-point networks which are modeled as graphs G(V, E), or bus-based networks which are modeled as hypergraphs H(V, E). By partitioning the backplane optical channels appropriately, the optical backplane can be dynamically reconfigured to embed arbitrary networks in real time. The optical backplane can thus provide terabits of low latency bandwidth for message-passing multiprocessors based upon graphs, and shared memory multiprocessors based upon broadcast busses. It is also shown that partitionable optical networks exhibit a significant improvement in performance over non-partitionable optical networks.
