Abstract
Because of the emergence of new services, the
requirements for
metropolitan area networks (MANs) have increased and
diversified.
Consequently, they are harder to meet - at least with the
existing
SONET/SDH networks - and new solutions are needed. VTT
Information
Technology has been researching next-generation SONET/SDH
(Synchronous
Optical Network/Synchronous Digital Hierarchy) networks,
which could meet
the diverse requirements of MAN while util
ising the
existing SONET/SDH network infrastructure.
