HPSR - Characterization of a shared buffer optoelectronic Packet Router
2011 IEEE 12th International Conference on High Performance Switching and Routing, 2011Co-Authors: Marina Thottan, Jesse E. Simsarian, Shivendra S. PanwarAbstract:The rapid increase in Internet traffic is forcing Packet Routers to grow in capacity to meet the demand. Optical Packet Routers with less buffering and a greater degree of optical transparency are actively being researched as a way to improve energy efficiency and capacity scaling over traditional electronic Routers. Since it is difficult to buffer Packets in the optical domain, in this paper we analyze the performance of a hybrid optoelectronic Packet Router. The Router architecture has multiple optical switch planes and a shared electronic buffer to resolve output-port contention. By using multiple ports on the switch planes for each input and output fiber, and by using some switch-plane ports to inter-connect the planes, we can achieve a relatively low Packet loss ratio in a Router with no buffer. In this case, most traffic can be switched using only the through optical paths of the Router without entering the shared buffer. The shared electronic buffer is primarily used to reduce the Packet drop ratio under periods of heavy loads and occasionally for optical regeneration of a Packet.We run extensive simulations to evaluate the performance of the Router with varying number of switch plane ports, number of connections to the electronic buffer, and number of interconnections between the switch planes. We show that the Router can provide good throughput, with realistic on-off bursty traffic and asynchronous Packet arrivals.

Demonstration of an Integrated Buffer for an All-Optical Packet Router
IEEE Photonics Technology Letters, 2009Co-Authors: J. D. Legrange, Jürgen Gripp, Jesse E. Simsarian, P. Bernasconi, Lawrence L. Buhl, David T. NeilsonAbstract:We demonstrate an integrated optical buffer, fabricated in silica, with data storage up to 100 ns. The buffer consists of an array of waveguide delays between matched arrayed waveguide grating (AWG) Routers and is designed for an all-optical Packet Router where buffering is required to resolve Packet contention. By changing the incoming signal wavelength, the output port of the first AWG Router is selected, thereby selecting a storage time in the buffer. All buffer channels have been demonstrated at 40 Gb/s with error-free operation and penalties of ~ 2-4 dB for bit-error rate =1times10-9.

Demonstration of a time buffer for an all-optical Packet Router
Journal of Optical Networking, 2007Co-Authors: J. D. Legrange, Jürgen Gripp, Jesse E. Simsarian, Dimitrios Stiliadis, P. Bernasconi, David T. Neilson, M. ZirngiblAbstract:We demonstrate an optical time buffer technology that meets the requirements of an all-optical Packet Router with a load-balancing architecture. The buffer is based on wavelength switching and an arrayed waveguide grating, which selects one of the delays in an array of fiber delay lines of increasing length. This buffer is unique because it enables the maximal sharing of delay lines among multiple input ports. Each of the N delays can simultaneously support N different wavelengths; therefore, for N input ports, the total buffer capacity is of the order of N3 Packets. Measurements performed with data at 10 Gbits/s and N=3 show that there is only a 2 dB bit error rate (BER) penalty resulting from wavelength switching.
