Abstract:
1. A computer program encoded on a non-transitory computer readable medium comprising a burst scheduling method in an Optical Burst Switching (OBS) system in which a plurality of nodes are connected through a mesh-type network, the method comprising: (a) determining, using a Burst Control Packet (BCP) transmitted from a previous node, whether an input burst is a Transit Data Burst (TDB) or an Several Hop Going (SHG) burst; (b) when the input burst is a TDB as a determination result of step (a) and an output channel to be used is already occupied by a specific SHG burst, reassigning the corresponding output channel such that the corresponding TDB burst occupies the output channel; and (c) when the input burst is an SHG burst as a determination result of step (a) and an output channel to be used is already occupied by another burst, discarding the corresponding SHG burst.
