Abstract
network. The protection pool evaluation is part of a shared protection scheme applied to a failure
dependent scenario and based on aggregated information dissemination. Two models based on a probabilistic
approach are proposed to provide a scheme that is scalable as the number of optical cross-connects (OXC),
fibres and wavelength multiplexing in a core network increases. Precisely, two models based on a binomial
and a beta-binomial distribution are presented. The evaluation of the models by simulation shows that both
models are attractive propositions to offer protected ¸-services that do not require an absolute protection
guarantee offered by (1:1) schemes or shared protection schemes requiring full network state information, or
using partial information but with less efficient use of the fibre utilisation.

N2 - The paper proposes an approach for calculating the protection pool size on each link in a mesh WDMrouted network. The protection pool evaluation is part of a shared protection scheme applied to a failure dependent scenario and based on aggregated information dissemination. Two models based on a probabilistic approach are proposed to provide a scheme that is scalable as the number of optical cross-connects (OXC), fibres and wavelength multiplexing in a core network increases. Precisely, two models based on a binomial and a beta-binomial distribution are presented. The evaluation of the models by simulation shows that both models are attractive propositions to offer protected ¸-services that do not require an absolute protection guarantee offered by (1:1) schemes or shared protection schemes requiring full network state information, or using partial information but with less efficient use of the fibre utilisation.
