Node Pacing for Small Optical RAM-Buffered Packet-Switching Networks

One of the difficulties with Optical Packet Switched (OPS) networks is buffering optical packets in the network. The only available solution that can currently be used for buffering in the optical domain is using long fiber lines called Fiber Delay Lines (FDLs), which have severe limitations. Moreover, the research on optical RAM presently being done is not expected to achieve a large capacity soon. However, the burstiness of Internet traffic causes high packet drop rates and low utilization in very small buffered OPS networks. The authors therefore propose a new node-based pacing algorithm for decreasing burstiness.
