A quantitative performance comparison study of all-optical slotted rings with different packet header speeds (original) (raw)

For full utilization of the high transmission bandwidth of optical fiber, several optically transparent switching nodes have been proposed for use in photonic LANs, MANs or B-ISDN access networks. In the switching 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 with optical signal processing for address detection supports higher header speed in packet transmission. In this paper, we analyze the performances of the optical ring networks which utilize the photonic packet switching nodes. A quantitative performance comparison study is carried out to observe the effect of header speed on the optical ring network performance. ᭧ 1997 Elsevier Science B.V.
