Cost, power consumption and performance evaluation of metro networks
Abstract : We provide models for evaluating the performance, cost and power consumption of different architectures
suitable for a metropolitan area network (MAN). We then
apply these models to compare today’s synchronous optical
network/synchronous digital hierarchy metro rings with
different alternatives envisaged for next-generation MAN: an
Ethernet carrier grade ring, an optical hub-based architecture
and an optical time-slotted wavelength division multiplexing
(WDM) ring. Our results indicate that the optical architectures
are likely to decrease power consumption by up to 75% when
compared with present day MANs. Moreover, by allowing
the capacity of each wavelength to be dynamically shared
among all nodes, a transparent slotted WDM yields throughput
performance that is practically equivalent to that of today’s
electronic architectures, for equal capacity.
