Abstract
1/1 resumo implantação de ospf em redes de arquitetura dividida um método é implantado em um elemento de rede que funciona como um dentre uma pluralidade de controladores para uma dentre uma pluralidade de áreas de uma rede de arquitetura dividida. o controlador fornece um plano de controle para a área da rede de arquitetura dividida em que o controlador é remoto a partir de uma pluralidade de comutadores que fornecem um plano de dados para a área de rede de arquitetura dividida. o controlador facilita o roteamento otimizado através da pluralidade de áreas da rede de arquitetura dividida fornecendo-se dados de custo de link intra-área limitados a outros controladores de outras áreas da rede de arquitetura dividida e a roteadores tradicionais de uma rede que inclui a rede de arquitetura dividida. os dados de custo de link intra-área limitados fornecem custos de cada travessia de trajetória mais curta possível da área do controlador sem fornecer todos os dados de custo de link interno.
