Abstract

The “switchless” all-optical network aims to provide a future single-layer, advanced transport architecture on a national scale. The single-hop, shared-access network employs time and wavelength agility (a WDMA/TDMA scheme), using fast tuneable transmitters and receivers, to set up individual customer connections through a single wavelength router, which is suitably replicated for resilience. While in a recent paper we reported the analysis and dimensioning of a switchless network assuming just the telephone traffic, we provide in this paper a new model, which contains innovative elements, and report original results assuming to deal with data traffic of two different types: constant bit rate (CBR) and variable bit rate (VBR). The innovation is based on the fact that the model considers more traffic flows with different traffic requirements (e.g., bandwidth, duration) as input to a group of time-slot connections on the same wavelength between two passive optical networks (PONs). We obtained analytical expressions of the main traffic characteristics (loss probability, throughput and overflowing traffic) both for the primary group of time-slots and for the secondary group of time-slots, to which the overflowing traffic streams enters.
