Abstract
Provided is a method for transmitting a burst using wavelength separation in an optical burst switching system, in which a plurality of nodes form a mesh network. The method includes the steps of generating, at a current node, a several hop going (SHG) burst arriving at a destination node by way of a plurality of nodes, allocating the generated SHG burst to a dedicated wavelength group to prevent the generated SHG burst from colliding with SHG bursts generated from previous nodes, and delivering the SHG burst to a next node, checking offset times of the SHG bursts generated from the previous nodes and classifying the SHG bursts according to the offset times, and allocating the SHG bursts separated according to the offset times to different wavelength groups and transmitting the SHG bursts to the next node. Using this method, it is possible to solve a problem of unfair competition among bursts according to the number of nodes that the bursts should transit in the optical burst switching system.
