Abstract

método e sistema para realizar acessibilidade da rota de destino no anel de acesso da rede de transporte de pacotes. a presente invenção se refere a um método de acessibilidade da rota de destino em anel de acesso de uma rede de transporte de pacotes (ptn). o método compreende a função de ligação entre um módulo de protocolo de resolução de endereços (arp) e um módulo de rota estática que é definida em uma interface de três camadas de um nó de convergência, o nó de convergência atualizada automaticamente a entrada da rota estática descoberta que corresponde a um endereço de destino de um nó de acesso de acordo com a entrada arp descoberta sobre cada nó de acesso; e o nó de convergência relata uma entrada da rota estática descoberta atual que corresponde ao endereço de destino do nó de acesso para um nó central e para as outras redes de acordo com um protocolo de rota dinâmica. a presente invenção também se refere a um sistema de acessibilidade de uma rota de destino em um anel de acesso de uma ptn ao mesmo tempo. por meio da aplicação do método e do sistema da presente invenção, onde as quebras ocorrem simultaneamente nas ligações entre os nós de acesso do anel de acesso e a linha de sincronização entre os nós de convergência, todos os nós de acesso associados com outro nó de convergência podem se comunicar normalmente com o nó central e outras redes, de modo a melhorar a capacidade de resistência à falha do nó de acesso na ptn.
