Abstract

resumo patente de invenção "sistema de redes e método para controlar o mesmo" [sumário] [objetivo] otimizar rapidamente uma rota mesmo quando o estado de um enlace ou similar de uma rede é alterado. [organização] quando um primeiro nó predeterminado e um segundo nó predeterminado são conectados de forma comunicável por meio de um enlace novo, o primeiro nó e o segundo nó transmitem, cada um, através de um meio de transmissão (unidade de processamento de roteamento de pacote 11) para outros nós que não o primeiro nó e o segundo nó, um sinal de notificação que tem informações que indicam que uma comunicação comunicável é feita pelo novo enlace e informações que indicam uma métrica para o primeiro nó ou o segundo nó, e cada um dos outros nós que receberam o sinal de notificação adiciona às informações que indicam a métrica do sinal de notificação uma métrica para si mesmo a partir de um nó imediatamente anterior que transmitiu o sinal e encaminha o sinal para mais outro nó através de um meio de encaminhamento (unidade de processamento de roteamento de pacote 11), e atualiza as informações de rota armazenadas na tabela de roteamento através de um meio de atualização (unidade de controle 12) quando o nó recebeu o sinal de notificação. [desenho selecionado] figura 1.patent pending "network system and method for controlling same" [summary] [objective] to quickly optimize a route even when the state of a link or the like of a network is changed. [organization] when a first predetermined node and a second predetermined node are communicably connected via a new link, the first node and the second node each transmit via a transmission medium (data routing processing unit). packet 11) for nodes other than the first node and the second node, a notification signal that has information indicating that a communicable communication is made by the new link and information indicating a metric for the first node or second node, and each of the other nodes that received the notification signal adds to the information that indicates the notification signal metric a metric for itself from an immediately preceding node that transmitted the signal and forwards the signal to another node through a medium. routing processing unit 11), and updates the route information stored in the routing table through and an update means (control unit 12) when the node has received the notification signal. [drawing selected] figure 1.
