Embodiment Construction

[0048] The technical solutions in the embodiments of the present invention will be described below in conjunction with the accompanying drawings. The accompanying drawings are used to help understand the technical solutions of the embodiments, and implementation may not be limited to the forms shown in the accompanying drawings.

[0049] In this embodiment, for each VPN that is assigned a routing label by a device, a strategy for VPN routing label distribution is configured. This strategy includes a routing label distribution method selected from more than two routing label distribution methods. Assign labels to VPN routes according to this policy. This method can diversify the label allocation methods of PE devices to VPN routes, which is helpful to give full play to the performance of PE devices or improve the forwarding performance of PEs. Detailed description will be given below.

[0050] According to the current methods for assigning labels to VPN routes by PE devices, ...

Abstract

The invention provides a method and a device for virtual private network label distribution for solving the problems of incomplete performance play or low message forwarding performance of label distribution equipment such as a backbone network edge device in the prior art. The method of the embodiment comprises: configuring a VPN route label distribution policy for VPNs in which route labels are distributed by the same set of equipment, wherein the policy comprises route label distribution modes selected from more than two route label distribution modules; and distributing labels for the routes of the VPNs according to the configured route label distribution policy. The embodiment also provides a corresponding device. According to the technical scheme, and the performance characteristics of equipment and the route label distribution modes are combined to allow the performance of the equipment to be fully played and ensure the message forwarding performance of the equipment.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a routing label distribution method and device for a virtual private network. Background technique [0002] Virtual Private Network (Virtual Private Network), referred to as VPN, is a private private network built using a public network. With its unique advantages, it has won more and more applications. For users, using VPN can reduce the cost and facilitate management. For operators, the existing infrastructure can be used to provide value-added services, which can expand the business volume of operations and create new business opportunities. [0003] Multi-Protocol Label Switching protocol MPLS (Multi-Protocol Label Switching) is a classification and forwarding technology that groups packets with the same forwarding processing method into one class, that is, Forwarding Equivalent Class (Forwarding Equivalent Class). MPLS was originally proposed as a protocol to inc...
