Algorithms of Unicast, Multicast and Broadcast Transmission for Optical Switches

Optical technologies for recent computer networks should provide high performance, ability to easy expansion and ensuring greater data´s safety. They are very popular and still very much under research. The paper concerns optical switching problem for broadcast, multicast and unicast traffic. Improvement of architecture represented by input-output matrix and broadcast-multicast matrix, which deals with the considered types of transmission, is presented. For the proposed system, new modified algorithms like LSA, QLSA, Exact and J-family are provided and investigated. In order to evaluate properties of developed algorithms, the experimentation system has been designed and implemented. As main index of performance the total penalty T_P is used. The idea of experimentation system, some results of research and properties of algorithms are discussed.
