Abstract:  The design and implementation of the high speed access mechanism for a fiber optic multiser-vice LAN is presented. The growing penetration of wideband services in conjuction with a considerable amount of real-time and interactive data traffic requires different handling of stream- and bursty-type communications. This task is accomplished through the use of a distributed hybrid switching protocol which employs an asynchronous dynamic Time Division Multiplexing (TDM) technique. The network comprises a Write channel in which each network node transmits and a Read channel where the transmitted information is duplicated and thus received by the network nodes. In parallel to the Write channel a Sense channel is responsible to detect the right of access for the node. The protocol provides bounded delay for the packet-switched traffic and small buffering memory for the circuit-switched traffic, which together with the network bit rate and the node processing time and capacity set the network efficiency. The experimental results of the implemented access mechanism are presented with respect to the node processing time and the network speed.
