Embodiment Construction

[0028] The present invention provides a packet forwarding scheme in a VPN network. By configuring routing groups on PE devices in the VPN network and configuring tunnel forwarding policies in different routing groups, different routing attributes can be selected according to the routing attributes of the packets. forwarding path.

[0029] The specific implementation of the present invention will be described in detail below by taking software implementation as an example. The VPN message forwarding device provided by the present invention runs on PE equipment. As the operating carrier of the device of the present invention, the hardware environment of the PE device usually includes at least a CPU, a memory, and a non-volatile memory, and of course may also include hardware such as a forwarding chip and an I / O interface. Please refer to figure 2 , image 3 as well as Figure 4 , the device includes: a saving unit, a generating unit and a forwarding unit. In an exemplary e...

Abstract

The invention provides a VPN message forwarding method and device. The method includes: storing tunnel forwarding policies corresponding to different routing groups in the same VPN, the routing groups being set according to routing attributes; generating a routing forwarding table according to the tunnel forwarding policy, and the routing forwarding table includes routing Correspondence between attribute and forwarding path; after receiving the user message sent by the CE device at the edge of the user network, look up the routing forwarding table, and forward the user message through the forwarding path corresponding to the routing attribute. Through the technical scheme of the invention, in the same VPN, different user messages can be forwarded through different paths, which meets the user's requirements for networking.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a message forwarding method and device in a VPN (Virtual Private Network, Virtual Private Network) network. Background technique [0002] Through VPN technology, a private network can be established on a public network and encrypted communication can be carried out. Since VPN technology has many advantages such as low cost and easy use, it is widely used in enterprise networks. [0003] Please refer to figure 1 Shown is a schematic diagram of the VPN network networking structure. Among them, the relevant terms involved are: [0004] CE (Customer Edge, user network edge equipment): connected to the service provider edge equipment through the interface. A CE can be a Layer 2 access device or a host. CE does not "perceive" the existence of VPN. [0005] PE (Provider Edge, service provider edge device): The edge device of the service provider network is directly ...
