    abstract = {OBS (Optical Burst Switching) networks have more blocking probability with respect to burst
movement. So it is challenging to schedule channels for OBS networks. Here we propose to develop Priority
Based Scheduling architecture based On Channel Utilization in OBS Networks. Herein initially, we classify
incoming packets by means of destination, loss and delay packets. We use Shaper architecture to determine
the size and departure time of the bursts. Based on the time taken for a burst, we calculate expanded priority
vector which considers CoS value of the job, Residual distance to the resource domain and a discrete value for
the job size (burst length). We use this priority class to schedule the bursts using preemptive latest available
unscheduled channel with void filling. Here, we preempt the overlapping bursts based on the priority and fill
it with new resources. After scheduling the slots, we made channel utilization to choose the optimal channel
with maximum defined channel utilization. Thus we determine the feasible data channel by performing bitwise
AND between new BDP and register R of each data channel in parallel.}
