The Stanford OCRL has designed HORNET-a novel optical packet-switched WDM MAN. The key advantages of HORNET are efficient bandwidth sharing among a large number of users and lower equipment cost than SONET. We are constructing an experimental testbed to investigate the capabilities of HORNET. The experimental results confirm the HORNET node's ability to transmit and receive optical packets with better than 10/sup -9/ BER, to correctly route packets according to their recovered destination node address carried by subcarrier signals, and to effectively handle data clock recovery on a packet-by-packet basis. The network simulation results on the queue depth and the packet latency prove the benefits of the VOQ over the single FIFO queue at heavy traffic load.
