We develop diverse routing schemes for dealing with multiple, possibly correlated, failures.
While disjoint path protection can effectively deal with isolated single link failures, recovering …

Fiber cut events reduce the capacity of wide-area networks (WANs) by several Tbps. In this
paper, we revive the lost capacity by reconfiguring the wavelengths from cut fibers into …

For a fast rotating condensate in a harmonic trap, we investigate the structure of the vortex
lattice using wave functions minimizing the Gross-Pitaevskii energy in the lowest Landau …

This paper presents a scheme in which a dedicated backup network is designed to provide
protection from random link failures. Upon a link failure in the primary network, traffic is …

The analysis of a public performance monitoring dataset reveals that reducing margins
necessarily amounts to trade availability off for capacity. After carefully establishing this fact …

Telecommunications networks need to guarantee that all node pairs involved in critical
service communications are highly available. Here we adopt a novel approach to the …

The exact calculation of all‐terminal reliability is not feasible in large networks. Hence
estimation techniques and lower and upper bounds for all‐terminal reliability have been …

A service-level agreement (SLA) typically specifies, among other metrics, the availability a
service provider (SP) promises to a customer. In an optical wavelength division multiplexing …

In data‐communication networks, network reliability is of great concern to both network
operators and customers. On the one hand, the customers care about receiving reliable …

To avoid huge data loss in the last mile of Internet service, Passive Optical Networks (PONs)
need to be designed with a high availability guarantee. Because next generation PON …
