In this paper, we investigate the problem of dynamic survivable routing in wavelength-
division-multiplexing optical networks and propose a new path-protection algorithm called …

This paper reviews recent progress in optical protection rings with the focus on transparent
optical protection rings. Different optical protection ring architectures, such as dedicated and …

Techniques, apparatus and systems for optical communications, including fiber ring
networks with protection switching to maintain optical communications when an optical …

In recent years, with the rapid growth of the Internet, the bandwidth demand for data traffic is
exploding. Optical networks based on wavelength-division multiplexing (WDM) technology …

This paper proposes and experimentally demonstrates an automatic-protection-switching
(APS) mechanism against distribution fiber breaks in passive optical networks (PONs). The …

We present the effectiveness of a reliable optical path network architecture that introduces
scalable photonic nodes and dedicated path protection. The assumed photonic nodes …

We consider the problem of routing the lightpaths of a logical topology of a WDM network on
an arbitrary physical topology, such that the logical topology remains, connected even after …

Our research study in this paper focuses on supporting differentiated resilience services in
IP/MPLS-over-WDM networks with minimum resources while guaranteeing the quality in …

We revisit the topic of optical layer protection from a motivation and deployment perspective.
We first discuss the changes that have occurred in optical networking in general and the …
