“…Several burst scheduling policies have been proposed in the past few years [2][3][4][5][6][7][8][9][10][11][12][13]. Turner [3] introduced the latest available unused channel (LAUC [14]) discipline also known as Horizon since it keeps track of the time on horizon to make the reservation.…”

This paper presents a novel channel scheduling policy for optical burst switching networks called least reusable channel (LRC). LRC decides to which interval of the output channel (void) an incoming burst should be allocated on the basis of reuse of the remaining voids. LRC dynamically uses information available to make allocation decisions. It is shown here that LRC produces lower blocking probability and distributes losses more uniformly among routes than do other existing scheduling policies.

“…Netak et al [8] proposed a channel scheduling policy called reverse scheduling. In reverse scheduling, feasible voids are searched first, and if there are no such voids, the void associated with the horizon is chosen.…”
