Embodiment Construction

[0032] In order to solve the problem that the existing technology cannot perform speed limit processing well for VPN, the present invention provides a method and device for realizing virtual private network traffic speed limit. The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments . It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] There are many different access modes for PE access side to access VPN, including: port access mode, port and VLAN (Virtual Local Area Network, virtual local area network) access mode, port and QinQ (QinQ is 802.1Q in 802.1Q It is a layer-2 tunneling protocol based on IEEE 802.1Q technology. By encapsulating the user's private network packets with an outer VLAN Tag, it carries two layers of VLAN Tags and traverses the carrier's backbone network, thereby providing users...

Abstract

The present invention discloses a method and device for realizing flow rate-limiting in a virtual private network (VPN). A rate-limiting index is applied for each VPN and / or VPN access, respectively; and a corresponding relation between the rate-limiting index and a flow parameter set by a user is configured. The method also includes the following steps: the corresponding rate-limiting index is queried according to a configured VPN access manner when a VPN message is received; a rate-limiting process is performed according to the queried rate-limiting index. By applying different rate-limiting indexes for different VPNs or VPN accesses in the present invention and according to the rate-limiting indexes, not only the rate-limiting for VPN flows can be realized on the access side of a provide edge (PE) device, but also the rate-limiting for different accesses in the VPN can be realized, so that the operator is enabled to provide different personalization services for different users and for different service types.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for realizing traffic speed limitation of a virtual private network. Background technique [0002] Virtual Private Network (VPN, Virtual Private Network) technology is a technology that uses public networks to realize private use. MPLS (Multi-Protocol Label Switching, Multi-Protocol Label Switching) VPN has the characteristics of low cost, good scalability, and high bandwidth. a wide range of applications. MPLS-based L2VPN, its network structure is as follows: figure 1 As shown, it mainly consists of CE (Custom Edge), P (Provider), and PE (Provider Edge), among which CE is the user edge device; PE is the operator edge device, which is mainly responsible for VPN access; P is the operator backbone network equipment , responsible for label forwarding. [0003] With the development of the telecom market, many services are opened based on VPN. When diffe...
