Abstract

Optical burst switching (OBS) control architecture considers two different models for management of offset-times in the network. A conventional OBS introduces an offset time (OT) between a control packet and a corresponding burst in soft-way by delaying the transmission of the burst in respect to the control packet in the edge node. Another idea for an OBS operation comes from optical packet switching (OPS) world and it intends to emulate OT by means of an additional fiber span (FS) introduced in the data path at the input port of core node. Although the conventional OBS has attracted lots of attention, in this paper we highlight that it possesses many difficulties that can be avoided easily in OT-emulated OBS
