Abstract
A method of deflection routing a packet in an all-optical communication network is described. Routing and destination information is contained in the address header of the packet and is generated by the originating node while still in the electrical domain before conversion to the optical domain. Receiving nodes process the address header in the optical domain using the information for their node from the address header. The address header is comprised of N node fields where N is the number of nodes on the optical network. Each node field contains routing information for a node on the optical network. Each node field contains at least one port field containing routing and address information associated with a port in the node.
