Abstract

método e sistema para realização de hot backup em nós de rede centralizada. a presente invenção se refere a um método para a realização de hot backup em um nó de rede centralizada, no qual um módulo de controle principal, e um módulo de controle de espera estão organizados, compreendendo: um túnel para o protocolo de reserva de recursos em engenharia de tráfego (rsvp-te) que contém dois caminhos comutados por rótulo (lsps): um lsp principal e um lsp de espera. o método adicionamento compreende: o módulo de controle principal recebe a informação de controle de lsp principal e a do lsp de espera configura a informação de identificação da informação de controle de lsp principal e a informação de controle do lsp de espera como ativo ou inativa de acordo com os estados atuais dos lsps principal e de espera, e sincroniza a informação de controle de lsp principal e a informação do lsp de espera para o módulo de controle de espera, e o módulo de controle de principal atual gera informações de encaminhamento de acordo com as informações de controle do lsp cuja identificação da informação é ativa, e encaminha um serviço após a comutação entre os módulos de controle principal e de espera. a presente invenção descreve também um sistema para a realização do método. a invenção reduz o tempo de comutação e o tempo de transmissão, e melhora a velocidade da transmissão do serviço.
