abstract = {This paper examines the economic viability
of two technologies - optical
circuit-switched (OCS)
networks and
optical burst-switched
(OBS) networks - in the core
network. We analyze and dimension OCS
network (OCSN) and OBS
network (OBSN) architectures for a range
of traffic demands given the constraints on the
network element capacities. We investigate the
effect of traffic grooming for both
of these architectures. We evaluate these
network architectures for a national core
network in Australia in terms
of their capital costs
and packet-blocking probabilities. We observe that OBSNs with traffic
grooming at the optical layer may become more
cost effective than OCSNs with traffic grooming at
both the IP and optical
layers for the same quality of service in terms
of blocking probability. The
cost advantage of OBSNs over OCSNs grows as
the capacity of the core
network increases. Hence, among the all-optical
networking options that do not involve buffering at
the core, OBS appears to be an attractive option especially for high-capacity
core networks.}
