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.
