Compared with fixed-grid optical network, flexible-grid optical network (FON) enabling
technologies could provide higher spectrum efficiency and thus more capacity. With more …

At present one can observe the increasing dependency of society on large-scale complex
networked systems. The consequences of faults of network elements are magnified by …

In this talk the cost of building resilient passive optical networks (PONs) is analyzed in
relation to the connection availability performance. Both standard and several novel PON …

For real-time services, protection is preferable for its fast failure recovery in optical networks.
Recently, sub-path protection has been proposed to provide scalable and efficient …

In this paper, we propose a planning heuristic called Locate-ONU-with-Lowest-Availability-
Requirement-First (LOWLARF) to compare the coverage capability of three previously …

This paper proposes two wavelength overprovisioning strategies that can be used to
improve the performance of path restoration in optical core networks under dynamic traffic …

Due to the high resource redundancy of full protection for requests multi-link failure in elastic
optical networks, a strategy of Reliability Oriented Probability Protection and Backup …

This paper proposes a novel failure recovery framework for multi-link shared risk link group
(SRLG) failures in optical mesh networks, called failure presumed protection (FPP). The …

Path-arc integer linear programming (ILP) models for shared backup path protection (SBPP)
in optical mesh networks generally contain many redundant constraints for calculating …

Survivability is mission-critical for elastic optical networks (EONs) as they are expected to
carry an enormous amount of data. In this paper, we consider the problem of designing …
