A Quantitative Evaluation of a Hybrid Electro-Optical Packet Switch Architecture

B.B. Mortensen (Denmark)


Modeling, simulation, hybrid electro-optical packetswitch and aggregation process.


Using optics to build large scale packet switches (>1Tb/s) has been proposed in the literature due to potential advantages regarding power consumption and scalability. The focus of this article is optical packet switches that operate in a time slotted synchronous mode. Since the timeslots are fixed length the incoming traffic needs to be aggregated into optical formatted packets (aggregation process). Optical formatted packets are announced to a central scheduler that controls the permutation of the optical switch backplane. In this article the aggregation process is investigated in conjunction with the central scheduling algorithm in order to make a quantitative evaluation.
