Abstract
The paper presents the simulation in VPI of all-optical routing based on the pulse-position modulation header processing (PPM-HP) scheme in an ultrafast photonic packet switched core network. In this network, optical core router employing PPM-HP utilizes a dedicated multi-wavelength pulse-position routing table (MW-PPRT) which results in a significant reduction of the number of routing table entries thus reducing the header processing time compared to the existing sequential routing table looking-up schemes. The reduced routing table also offers embedding multiple transmitting modes (unicast, multicast and broadcast) in an optical layer and improves scalability of the core network where the number of core/edge nodes could be altered without changing the number of routing table entries. Details of simulation schematics and results of the router operating at 100 Gbit/s are presented.
