Abstract

"SISTEMA, MéTODO E APARELHO QUE ISOLAM REDE PRIVADA VIRTUAL (VPN) E TRáFEGO DE EMPENHO MELHOR PARA RESISTIR à NEGAçãO DE ATAQUES DE SERVIçO". Uma arquitetura de rede (20) de acordo com a presente invenção inclui uma rede de comunicação que suporta uma ou mais Redes Privadas Virtuais (VPNs) com base em rede. A rede de comunicação inclui uma pluralidade de roteadores de limite (22a-22d) que estão conectados por meio de ligações de acesso aos roteadores de borda do CPE (24b-24d e 25a-25d) pertencendo a uma ou mais VPNs. Para evitar do tráfego de fora de uma VPN de cliente (por exemplo, tráfego de outras VPNs ou da Internet em geral) degradar a QoS fornecida para trafegar dentro da VPN de cliente, a presente invenção dá precedência ao tráfego intra-VPN sobre o tráfego extra-VPN em cada ligação de acesso de cliente através da priorização da ligação de acesso ou alocação da capacidade da ligação de acesso, de modo que o tráfego extra-VPN não pode interferir com o tráfego intra-VPN."SYSTEM, METHOD AND APPARATUS ISOLATING VIRTUAL PRIVATE NETWORK (VPN) AND BETTER TRAFFIC TO RESIST WITH NEGATION OF SERVICE ATTACKS". A network architecture (20) according to the present invention includes a communication network that supports one or more network-based Virtual Private Networks (VPNs). The communication network includes a plurality of boundary routers (22a-22d) that are connected via access links to the CPE edge routers (24b-24d and 25a-25d) belonging to one or more VPNs. In order to prevent traffic from outside a client VPN (for example, traffic from other VPNs or from the Internet in general) from degrading the QoS provided for traffic within the client VPN, the present invention takes precedence over intra-VPN traffic over traffic. VPN on each client access connection by prioritizing the access connection or allocating the capacity of the access connection, so that extra VPN traffic cannot interfere with intra-VPN traffic.
