Abstract In Optical Burst Switching (OBS), packets
travel through the network core as part of longer-size
optical bursts, which do not suffer electronic conversion
until they reach an eggress point. Typically, such opti-
cal bursts comprise tens or hundreds of packets, which
are assembled/deassembled at border nodes. During the
burst-formation process, each arriving packet must wait
until the final burst is complete, which clearly adds an
extra delay on each packet in the burst, especially on
those arriving earlier. However, such burst-assembly de-
lay may be excessive for the appropriate performance of
