Patent

CA 2521540

Methods and apparatus for performing NAT are disclosed. Specifically, NAT is performed at a service provider network device associated with an interface of a service provider network. When a packet is sent from a VPN to a node outside the service provider network (e.g., to access a shared service), the packet includes a VPN identifier (or VRF identifier) In accordance with various embodiments, each packet includes an MPLS tag that includes the VPN identifier. The VPN identifier is stored in a translation table entry. The storing of the VPN identifier will enable a reply packet from the shared service network to the customer VPN to be routed using a routing table identified by the VPN identifier.

L'invention concerne des procédés et des dispositifs destinés à la traduction d'adresse réseau (NAT). Plus précisément, la traduction d'adresse réseau est réalisée au niveau d'un dispositif de réseau de fournisseur de service associé à une interface d'un réseau de fournisseur de service. Lorsqu'un paquet est transmis par un VPN à un noeud situé hors du réseau du fournisseur de service (pour accéder à un service partagé, par exemple), le paquet utilise un identifiant VPN (ou identifiant VRF). Dans divers modes de réalisation de l'invention, chaque paquet comprend une étiquette de commutation multiprotocoles (MPLS) contenant l'identifiant VPN. L'identifiant VPN est stocké dans une table de traduction. Le stockage de l'identifiant VPN va permettre le routage d'un paquet de réponse transmis par le réseau de service partagé au client VPN au moyen d'une table de routage identifiée par l'identifiant VPN.
