Data plane restart without state change in a control plane of an intermediate network node

   
   

A system and technique restarts a data plane of an intermediate node, such as an aggregation router, of a computer network without changing the state of a control plane in the router. The aggregation router comprises a control plane that includes a supervisor processor configured to manage traffic forwarding operations of the node. To that end, the supervisor processor maintains a current state of the control plane pertaining to, e.g., routing protocols and interface states of line cards within the router. The aggregation router further comprises a data plane that includes hardware components, such as a forwarding engine, configured to perform forwarding operations for data forwarded by the router.

Um sistema e uma técnica reiniciam um plano dos dados de um nó intermediário, tal como um router do aggregation, de uma rede de computador sem mudar o estado de um plano do controle no router. O router do aggregation compreende um plano do controle que inclua um processador do supervisor configurarado para controlar operações do forwarding do tráfego do nó. A essa extremidade, o processador do supervisor mantem um estado atual de pertencer plano do controle a, por exemplo, protocolos e estados de distribuição da relação da linha cartões dentro do router. O router do aggregation mais adicional compreende um plano dos dados que inclua componentes de ferragem, tais como um motor do forwarding, configurarado para executar as operações do forwarding para dados enviadas pelo router.
