This work introduces a new shared segment protection scheme that ensures both node and link protection in an efficient manner in terms of cost and band...

BibTeX reference

The focus of this paper is on the design of the so-called Optical Wide Area Networks (OWANs), i.e., optical networks that cover broad areas. Our objective ...

BibTeX reference

The Protected Working Capacity Envelope (PWCE) concept was proposed by Grover (2004) in order to simplify network and operation management in survivable WDM ...

BibTeX reference

The multi-agent resource allocation problem corresponds to the negotiation of <i>m</i> resources among <i>n</i> autonomous agents, in order to maximize a soc...

BibTeX reference

Routing for shared protection has received a lot of interest in the last few years. A large number of the studies focus on minimizing the network transport ...

BibTeX reference
and

Routing for Overlapping Segment Shared Protection (OSSP) in multi-domain networks is more difficult than that in single domain networks because of the scalab...

BibTeX reference
, , , and

We investigate a first column generation (CG) formulation for the design of failure independent path-protecting (FIPP) <i>p</i> -cycle survivable transport ...

BibTeX reference

We study two basic problems of probabilistic reasoning: the probabilistic logic and the probabilistic entailment problems. The first one can be defined as f...

BibTeX reference
and

The dynamic routing problem for Overlapped Segment Shared Protection in multi-domain networks has not received a lot of interest so far as it is more difficu...

BibTeX reference

We present a review of several column generation formulations for the Routing and Wavelength Assignment (RWA) problem with the objective of minimizing the b...

BibTeX reference
, , and

We study the problem of routing and wavelength assignment (RWA) in a WDM optical network under different hop assumptions, i.e., with and without wavelength ...

BibTeX reference
