Nonpreemptive scheduling of optical switches
A Kesselman, K Kogan - IEEE Transactions on …, 2007 - ieeexplore.ieee.org
Many high-speed routers today use input-queuing (IQ) architectures with a crossbar
switching fabric based on optical technology. Packets in the input queues are divided into
cells of unit length, and the goal is to find a schedule of minimum makespan that forwards all
packets to the output ports. The problem is complicated since, in optical switches, so-called
configuration delay, that is the time required to reconfigure the switching fabric, is non-
negligible with respect to the cell transmission time. We aim to design a scheduler whose …
