An addressing independent networking structure favorable for all-optical packet switching

All-optical packet switching (AOPS) technology is essential to fully utilize the tremendous bandwidth provided by advanced optical communication techniques through forwarding packets in optical domain for the next generation network. However, long packet headers and other complex operations such as table lookup and packet header re-writing still have to be processed electronically for lack of costeffective optical processing techniques. This not only increases system complexity but also limits packet forwarding speed due to optical-electronic-optical conversion. Lots of work of improving optical processing techniques to realize AOPS is reported in the literature. Differently, this paper proposes a new networking structure to facilitate AOPS realization and support various existing networks through simplifying networking operations. This structure only requires an AOPS node to process a short packet header to forward packets across it with neither table lookup nor header re-writing. ...
