2003 Optical Transmission Systems and Equipment for WDM Networking II  
In contrast to optical packet switching, OBS aggregates and assembles packets electronically into bursts of variable length according to destination and QoS class at the edge of the network.  ...  On the other hand burst size and burst characteristics have an impact on network performance and node architectures.  ...  In an all-optical burst switch, a reservation conflict exists if the wavelength on which a burst arrived to he node is blocked on the designated output fiber by a different burst.  ...
