The authors propose MaTPi, a new media-access protocol for theefficient utilization of resources in a local-area optical WDMA network.Most of the earlier work on reservation based media access protocols forsingle-hop optical networks has assumed the availability ofstate-of-the-art transmitters and/or receivers which are capable oftuning to the required wavelengths within nanoseconds. Their protocoloperates in the region where the tuning times of the end-devices are ofthe same order of magnitude as the transmission time of a packet. In thebasic MaTPi protocol, network throughput is improved by effectivelyoverlapping the tuning duration of a transmitter in a node with thetransmitting times of lasers in other nodes. They extend this basicprotocol to the mult-MaTPi protocol, where each node has more than onetransmitter to further improve the bandwidth efficiency of the network.Preliminary simulation results indicate that this practical protocol isindeed capable of achieving high throughput with low-cost, off-the-shelfcomponents. A number of extensions to this protocol are also discussed
