A QUANTITATIVE PERFORMANCE COMPARISON STUDY OF ALL-OPTICAL SLOTTED RINGS WITH DIFFERENT PACKET HEADER SPEEDS

For full utilization of the high transmission bandwidth of optical fib er, several optically transparent switching nodes have been proposed f or use in photonic LANs, MAN's or B-ISDN access networks. In the switc hing nodes, payload speed is transparent to optical speed while header speed remains at 155 Mbps or 622 Mbps for address processing by node control electronics. Another type of photonic packet switching node wi th optical signal processing for address detection supports higher hea der speed in packet transmission. In this paper, we analyze the perfor mances of the optical ring networks which utilize the photonic packet switching nodes. A quantitative performance comparison study is carrie d out to observe the effect of header speed on the optical ring networ k performance. (C) 1997 Elsevier Science B.V.
