A novel self-protection scheme for an Ethernet passive optical network is introduced and
studied at both the physical and the media access control layers. The scheme is simple and …

Multi-core fiber (MCF) is one of the promising space-division multiplexing technologies to
increase the capacity of optical networks. MCF-based networks have two challenges. One is …

A well-recognized problem in high-speed all-optical networks is that fibres and switches
frequently fail. When a network, designed in a non-robust way, encounters such kind of …

In optical networks, shared-backup path protection (SBPP) can optimize network resources
utilization in scenarios where connection resilience requirements are not achieved without …

Since each wavelength channel has the transmission rate over several gigabits per second,
the failures of fiber links may lead a lot of services to be blocked. Therefore, the survivability …

Spectrum conflict during primary and backup routes assignment in elastic optical networks
results in increased resource consumption as well as high Bandwidth Blocking Probability …

Elastic Optical Network (EON) architectures are considered as a very promising solution for
both huge bandwidth and flexible connection provisioning in next generation optical …

With the increase of size and number of shared risk link groups (SRLGs) in WDM networks,
path protection tends to have longer working paths and backup paths due to SRLG-disjoint …

Failure resilience is one of the desired features of the Internet. Most of the traditional
restoration architectures are based on single-failure assumption which is unrealistic …
