—A local lightwave network can be constructed by employing two-way fibers to connect nodes in a passive-star physical topology, and the available optical bandwidth may be accessed by the nodal transmitters and receivers at electronic rates using wavelength-division multiplexing (WDM). The number of WDM channels, w, in such a network is technology-limited(More)
We introduce a new technique for providing security in a broadcast-and-select, wavelength-division-multiplexed (WDM) optical network. The approach provides privacy of communications by employing a novel challenge-response scheme and exploiting the tuning delay inherent in optical receivers. The proposed technique can be integrated easily into any existing(More)
Multicast network traac is information with one source node, but many destination nodes. Rather than setting up individual connections between the source node and each destination node, or broadcasting the information to the entire network, multicasting eeciently exploits link capacity by allowing the source node to transmit a small number of copies of the(More)
