“…DRAFT April 23, 2023 The works by Halder et al [14], [15], [21] investigated the provisioning of protected services under the LD-MPR scenario and also utilized genetic algorithm to find optimized solution for paths and regeneration sites selection [15], routing paths and fiber core selection [21] and decision on how many division (either 2 or 3) the service is segmented [14]. All works consider a static traffic scenario.…”

“…We assume that for each arriving request, the number of subcarriers to be allocated is known in advance (this is similar to the RSA strategy used in [7]). We have also not considered minimizing power consumption arising from the use of optical routers, amplifiers and bandwidth-variable transponders [23], [24] and [25]. We leave these problems as future scope of study.…”

Due to the high bandwidth and low latency, optical networks have emerged as ideal candidates for supporting grid applications. As optical Wavelength Division Multiplexed (WDM) networks migrate to the next generation of flexible Orthogonal Frequency Division Multiplexed (OFDM) networks, it becomes necessary for the grid applications to be supported in the next generation of optical grids. As survivability is a key issue in optical grids, we address the problem of online network dimensioning and survivability of OFDM based optical grids. The most common cause of failure is known to be a fibre cut and so in this paper we have addressed the problem of protecting OFDM based transparent optical grids against any arbitrarily single link failure. For ensuring survivability we have used shared path protection. For network dimensioning we have used the well-known anycast principle for optical grids : a job can be relocated to another resource (or server) of similar type. To the best of our knowledge, this is the first paper to address the problem of online dimensioning and survivability of OFDM based transparent optical grids. We first propose an Integer Linear Program (ILP) formulation for the problem and then a heuristic algorithm, Online Dimensioning with Shared Path Protection (ODSPP) that can solve the problem in polynomial time. We compare the results obtained from the heuristic with that of the ILP and traditional shared path protection (SPP) without relocation. Performance comparisons show that ODSPP is highly capacity efficient and can be used to obtain near optimal results. The average percentage decrease in connection blocking probability over all experiments using ODSPP is 20.07 percent.

“…As duas abordagens são consideradas complementares, sendo a protec ¸ão um esquema proativo e a restaurac ¸ão, um esquema reativo que provêm a utilizac ¸ão eficiente dos recursos ópticos disponíveis para garantir a sobrevivência da rede . Mecanismos de protec ¸ão [Júnior and Drummond 2017, Anoh et al 2017, Assis et al 2019] possuem um plano pré-definido com recursos redundantes reservados/alocados para prover a recuperac ¸ão de falhas, enquanto que a restaurac ¸ão [Shen et al 2016, Regis et al 2018, Ferdousi et al 2020, Halder et al 2020, da Silva Oliveira and Fonseca 2019 estabelece este plano considerando os recursos disponíveis após o evento da falha. Ao mesmo tempo em que garantem 100% de recuperac ¸ão, as estratégias de protec ¸ão apresentam custo elevado uma vez que os recursos de backup são utilizados somente se a falha ocorrer, essa por sua vez, é imprevisível.…”

As Redes Ópticas Elásticas (Elastic Optical Networks EON) tem se mostrado uma solução para o futuro das redes de transporte óptico. No entanto, eventos de falhas podem causar a perda vigorosa de dados. Para isso esquemas de proteção e restauração tem sido desenvolvidos a ﬁm de minimizar tal prejuízo, a exemplo deste trabalho que propõe um esquema de sobrevivência com degradação de banda e atraso na restauração para conexões de baixa prioridade transmitidas no caminho de backup de conexões de alta prioridade. Comparações com a estratégia de proteção de caminho com backup dedicado demonstram superioridade em nosso algoritmo salientando que a política de degradação favorece redução da probabilidade de bloqueio.
