Abstract

MéTODO DE PROCESSAMENTO DE FALHA EM UMA REDE DE PACOTES DE ESTRUTURA DE áRVORE, E, ARRANJO EM UMA REDE DE PACOTES DE ESTRUTURA DE áRVORE. A invenção se refere a processamento de falha em uma rede em estrutura de árvore (NW1) que tem nós de fronteira (ENi ... EN4) e nós de comutação (SW1 ... SW4) interconectados por linhas (Li). VLANs (VLAN1 VLAN3) são estabelecidas de modo que pelo menos elas uma delas forneça conectividade em caso de qualquer falha única. As VLANs podem ser estabelecidas usando árvores abrangentes. Entre os nós de fronteira, emissores (EN3) radiodifundem mensagens ativas (Ai, A2, A3) regularmente nas VLANs e notificadores (EN2) notificam as mensagens ativas. Uma mensagem ativa perdida indica uma falha (CD 1) em uma VLAN (VLAN2) e o notificador (EN2) radiotransmite mensagens de falha (F 1, F2, F3) correspondentes nas VLANs. Quando todas as mensagens ativas (Ai, A2, A3) aparecem novamente, o notificador (EM2) radiotransmite mensagens de reparo (Ri ,R2, R3) correspondentes. Se os notificadores não notificam uma falha, os nós (ENi. EN4), com nenhum papel especial, efetuam uma função similar que o notificador (EN2), um pouco mais lento. O processamento de falha é rápido, robusto, usa poucas mensagens, aumenta somente um pouco a carga de tráfego na rede (NWi) e é condizente com os padrões atuais.
