Abstract

"MéTODO PARA DISTRIBUIçãO DE ROTA EM OTIMIZAçãO DE MúLTIPLOS SERVIçOS DE REDE DE TRANSMISSãO SDH". A presente invenção refere-se a um processo de distribuição de rota para implementar a otimização de múltiplos serviços em Rede de Transmissão de Hierarquia Digital Síncrona, que compreende as seguintes etapas: A. dividir a rede de transmissão SDH em sub-redes em termos de anéis para formar uma pluralidade de sub-redes em anel, calculando as rotas iniciais de toda a demanda de serviços na rede de transmissão SDH; B. julgar se há sobrecarga de recurso de elo entre as sub-redes e dentro de sub-redes; caso positivo, recalcular a rota; C. julgar se o índice de equilíbrio de carga é satisfeito pela sub-rede em anel; caso positivo, executar o ajuste de rota; D. depois da divisão das sub-redes em sub-redes de borda e sub-redes de núcleo, julgar se o indicador agregativo de cada elo nas sub-redes de núcleo satisfaz a condição de convergência; caso negativo, verificar se os tempos de cálculo de rota excedem o limite; caso positivo, terminar; de outro modo, recalcular as rotas correspondentes. Em alusão à presente invenção, são obtidos não apenas o recurso de rede mínimo a ser ocupado e a carga de rede a ser equilibrada, mas também a eficiência da distribuição de rota que é aumentada na rede em grande escala, a ótima solução aproximada sendo adquirida, tornando, portanto, o efeito da otimização de múltiplos serviços mais estável e excelente.
