Availability and Operability in Optical Transport Network Architectures

Abstract

A typical optical transport network interconnects multitudes of offices. With the advent of the
Internet of Things (IoT) networking approach, it has become necessary for such transport structures to be
flexible enough to accommodate heterogeneous communication services that generate escalating traffic
loads every time. It is also key not only to accommodating continuously escalating traffic levels, but also to
maintaining a consistent Quality of Service, operability as well availability. This can only be achieved
through the provisioning of effective and dynamic network control. In this paper, we explore the various
operational issues such as incompatibilities in terms of physical layer transmission requirements and other
control and management challenges emerging in present and future/ (envisaged) optical transport networks.
