Neste artigo, propomos um método de planejamento heurístico para acomodar com eficiência a demanda de caminho multicamada dinâmico (MLP) em redes multicamadas que consistem em uma camada de multiplexação por divisão de tempo (TDM) e uma camada de multiplexação por divisão de comprimento de onda (WDM); o objetivo é alcançar a acomodação flexível do aumento da capacidade e da diversificação das demandas de rotas. Além da preparação dos links na camada TDM e da rota e slots de frequência para o caminho óptico elástico a serem estabelecidos, o MLP requer a seleção de um modo operacional apropriado, consistindo em uma combinação de formatos de modulação e taxas de símbolos suportadas por sinais digitais coerentes. transceptores. Nosso método de planejamento MLP proposto define uma política de planejamento para cada um desses parâmetros e incorpora os valores calculados pela combinação dessas políticas em um gráfico auxiliar, que permite que os parâmetros de planejamento sejam calculados para os requisitos de demanda MLP em uma única etapa. Simulações revelam que a escolha do modo operacional reduz significativamente a probabilidade de bloqueio e demonstram que os pesos das arestas no grafo auxiliar permitem o planejamento do MLP com características adaptadas à demanda do MLP e aos requisitos da rede. Além disso, avaliamos quantitativamente o impacto de cada política de planejamento nos resultados do planejamento do MLP.

Abstract: In this paper, we propose a heuristic planning method to efficiently accommodate dynamic multilayer path (MLP) demand in multilayer networks consisting of a Time Division Multiplexing (TDM) layer and a Wavelength Division Multiplexing (WDM) layer; the goal is to achieve the flexible accommodation of increasing capacity and diversifying path demands. In addition to the grooming of links at the TDM layer and the route and frequency slots for the elastic optical path to be established, MLP requires the selection of an appropriate operational mode, consisting of a combination of modulation formats and symbol rates supported by digital coherent transceivers. Our proposed MLP planning method defines a planning policy for each of these parameters and embeds the values calculated by combining these policies in an auxiliary graph, which allows the planning parameters to be calculated for MLP demand requirements in a single step. Simulations reveal that the choice of operational mode significantly reduces the blocking probability and demonstrate that the edge weights in the auxiliary graph allow MLP planning with characteristics tailored to MLP demand and network requirements. Furthermore, we quantitatively evaluate the impact of each planning policy on the MLP planning results.
