Abstract-- To reduce contention in Optical Burst Switched
networks, data bursts are preceded by the so-called Burst Control
Packets, which are sent a given offset time in advance in order to
advertise of the forthcoming burst arrivals. However, this policy
of one-way in-advanced reservation produces the so-called Path
Length Priority Effect, which benefits BCP reservations with high
offset values against those with smaller offset times. This effect
not only brings an unfair treatment to bursts with different offset
values, but also leads to a serious degradation of global network
performance.
