Paper Abstract

Generally pair control architecture is adopted in telecommunication systems to save software processing time to setup both-way paths between a sender and a receiver. We have introduced this into a photonic switch fabric (PSF), which is a key instrument of a developed photonic label switch router (PLSR). The PLSR is to be operated as a photonic router in an optical Internet system to guarantee QoS (quality of service) and the transmission bandwidth by providing end-to-end wavelength LSPs (label switched paths). In contrast to conventional PSFs for both-way communications that do not have the capability to save switching elements and its control circuits, the proposed architecture enables us to save them drastically. General configuration of an N×N PSF is described in addition to the developed 3×3 PSF.
