Signaling-Free Optical Burst Switching
Overview In WDM mesh networks, wavelengths on a link are exclusively assigned to demands with no sharing. This can lead to poor utilization because data traffic often tends to be bursty with long periods of low traffic rates. Optical Burst Switching (OBS) has been proposed to solve this problem by allowing multiple demands to share the same channel capacity at different times. It buffers the incoming data at the edge nodes and transmits when the buffer gets sufficiently full. By allowing multiple demands to have overlapping paths and allocating them to a demand only during burst transmission, it improves utilization. This paper presents a scheme that avoids signalling and cross-connect set-ups, dramatically reducing the delays and costs of OBS in all-optical networks.
