Transfer method and the transfer device of the optical packet in optical packet switch network

摘要

Topic Transfer method and the transfer device of the optical packet in the optical packet switch network which delay time can be compatible with the priority processing of the optical packet of specification low low at cost are offered. SolutionsLabel information and information precedence, arrival time is detected from the optical packet which was transmitted and (S1), output port number is calculated from label information and (S2), output port number of the optical packet of rear arrival and the optical packet of the first-come is the same, at the same time, output time of the optical packet of rear arrival and the optical packet of the first-come is piled up, at the same time when, precedence of the optical packet of rear arrival is higher than precedence of the optical packet of the first-come, (S3 - S4), specified delay time to make the optical packet of the first-come delay, during delay in the optical packet of the first-comeChanging the output port of the node which confronts, output port number of beginning it transfers to the output port which differs, prefers the optical packet of rear arrival and transfers to the output port of output port number of beginning (S5 - S7).
