Abstract

Constructing multi-Terabit switches and routers entirely out of electronic cross-bars require multiple racks of switches and huge number of interconnects. The cost and power consumption of such a system is very high and has a limited scalability. The all-optical switching has the problem of buffering and processing and the construction of multi-terabit switches and routers based on all-optical switching is not feasible in the near future. However, based on a hybrid approach, using optical cross-bars with nanosecond switching time and large bandwidth and DWDM interconnects in conjunction with electrical memory, one can construct huge and highly scalable switches and routers.
