Joshua Lawrence Benjamin, Adam Funnell, Philip Michael Watts, Benn Thomsen
2017 2017 IEEE 25th Annual Symposium on High-Performance Interconnects (HOTI)  
Optical switches can provide higher capacity and port counts, and hence, can be used to transform data center scalability.  ...  In this paper, we present a pipelined and highly parallel electronic scheduler that configures the high-radix (1000-port) optical packet switch.  ...  The optical switch architecture demonstrated in [9] scales to over 1000 ports on the data plane but requires a scheduler performing dynamic wavelength assignment that is also scalable to 1000 ports and  ...
