Improvement of Input Buffer Optical IP Switch by Introducing Parallel Read-Out
نویسندگان
چکیده
An input buffer type optical switch is one of the most important switching systems. Conventionally an FIFO read-out procedure is used for the input buffer type optical switch, however, the FIFO procedure gives a head of line limit to its switching performances. The purpose of this paper is to introduce a parallel read-out procedure to the input buffer type optical switch, and to show that transferring performances of the input buffer type are improved drastically by the parallel read-out procedure. The parallel read-out structure for an optical switch is configured by wave length multiplexing, star couplers, and NOLM buffer memories. The performance evaluations have been done by computational simulation based on arrival, buffering, and transferring of variable size IP packets.
