Achieving accurate and efficient fault localization in large transparent all-optical networks
(TONs) is an important and challenging problem due to unique fault-propagation, time …

We propose lightpath establishment techniques for transparent optical networks, valid for
both centralized path computation (ie, performed by a path computation element—PCE) and …

In transparent optical networks, signals propagate over all-optical lightpaths. The absence of
regenerating devices that act in the electrical domain renders end-to-end monitoring difficult …

Transparent all-optical networks introduce a challenging problem of achieving efficient and
accurate full-coverage fault-localization. In this paper we present a novel and efficient …

Protection against failures, by providing alternative paths or backup equipment, is a
necessary component of network design. This chapter covers some of the major classes of …

In recent years, following the deployment of WDM networks, fault detection and localization
has become a challenging issue in networks with high reliability. Optical layer monitoring …

Optical network disaggregation is a novel technological paradigm enabling the mitigation of
lockin vendor constraints imposed within legacy systems, by aiming to standardise the …

We propose a lightpath establishment technique for transparent optical networks, exploiting
the path computation element (PCE) architecture, which leverages an end-to-end estimation …
