“…Each of the nodes on a subtending ring is equipped with a fixed wavelength drop, a tunable laser, and a power splitter. This approach promises high connectivity on a larger scale network [5], [6] but faces implementational challenges such as power budget limitation due to cumulative splitter insertion losses and synchronization problems both in the core and in subtending rings. We propose a ring photonic slot routing network in which composite packets are generated locally at each node with a single tunable transmitter.…”

We propose and demonstrate experimentally a novel technique for packet switching on a ring network. We use the wavelength dimension to increase the transmission line rate and a novel packet-stacking technique to add/drop packets. Packet stacking is used for transport rate multiplication and for equal loading of wavelengths on the physical layer. Packet stacking, switching, and unstacking have been successfully demonstrated on a four-node hubbed ring network serving five source-destination pairs on four wavelengths. Each wavelength was running at 1-Gb/s bit rate.

“…In [11] a photonic switch that performs header extraction, recognition and replacement, all in the optical domain, is presented. However in [12] it is noted that "since optical technology is still in its early stage, optical processing is not yet a mature and viable alternative to the electronic processing of packet header".…”

Altering the internal structure of an ATM switch fabric, based on the correlation among ports, can be proved to be advantageous in terms of performance, especially in LAN or campus ATM switches, where we witness stronger traffic correlation. Such reconfiguration can be easily performed in the optical domain, using simple optical elements. We prove the performance improvement, by applying data collected from a campus production ATM switch onto our proposed architecture.
