Abstract
um método e dispositivo para detectar grupos de enlace de risco compartilhado são divulgados. o método compreende injetar um feixe de sonda, respectivamente, em um primeiro enlace de teste e um segundo enlace de teste. o método inclui adicionalmente registrar, respectivamente, uma primeira curva de uma potência variável no tempo correspondente à primeira retroiluminação e uma segunda curva de uma segunda potência variável no tempo correspondente à segunda retroiluminação; calcular um valor de semelhança para a primeira curva e a segunda curva; e julgar, com base no valor de semelhança, se o primeiro enlace de teste e o segundo enlace de teste estão localizados no mesmo grupo de enlace de risco compartilhado. o método e o dispositivo para detectar grupos de enlace de risco compartilhado providos por modalidades da presente invenção detectam, através de testes, uma característica de potência de retroiluminação de um feixe de sonda em enlaces de teste e, com base nessa característica de potência unidimensional, julgam se os enlaces de teste estão no mesmo grupo de enlace de risco compartilhado, os quais são mais simples em aplicação do que aqueles do estado da técnica.
