Multi-slice Traffic Engineering Method for Optical Packet/Path Integrated Networks

This paper proposes a novel traffic engineering method for improving the throughput characteristics of optical packet forwarding in an optical packet / path integrated network. This method is based on bypassing optical packets rejected from a highly-loaded optical packet switch onto one of the adjacent packet switches via an optical path to increase the network throughput. Since the formation of a bypass is equivalent to sharing the buffers of two or more optical packet switches, the packet loss rate can be reduced even by the same buffer length. Or the buffer length can be reduced to achieve the given packet loss rate.
