Multi-terabit hybrid photonic switching and routing
نویسندگان
چکیده
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.

Performance Evaluation of a New Photonic ATM Switching Architecture Based on WDM
A new gigabit ATM photonic switching architecture is here presented and first experimental results are reported. The matrix is based on wavelength encoding of cells and on the broadcast-and-select principle for routing. A suitable management of fibre delay lines allows alloptical output queueing inside each switching element. These output buffered switching elements are then interconnected in a...
