Problems solved by technology

[0004] The problem brought about by this is that the total bandwidth of users may double. For operators who want to limit the bandwidth of users, this result is unacceptable, especially when operators expand capacity through trunks, they have to manually adjust each time. Modifying the configuration will make operation and maintenance complicated; if not modified, the actual bandwidth of the user may far exceed the bandwidth purchased by the user, causing losses to the operator

Embodiment Construction

[0016] In order to facilitate the understanding of the present invention, the specific implementation process of the present invention will be described below in conjunction with examples.

[0017] figure 1 A link bandwidth adjustment method provided by an embodiment of the present invention is shown. The links are two inter-board load sharing links in a virtual private network, including a first link and a second link. The method includes:

[0018] 101: Perform link traffic statistics on the first link and the second link according to a preset period;

[0019] 102: Determine whether bandwidth adjustment needs to be performed on the first link and / or the second link according to the link traffic statistics result;

[0020] Specifically, if the statistics of the first link and the second link traffic in one or more preset periods both reach the initial bandwidth or both do not reach the initial bandwidth, it is determined that bandwidth adjustment is not required; if If the t...

Abstract

The embodiment of the invention relates to a method and a device for adjusting link bandwidth. Links adopt two single-board spanning load sharing links in a virtual private network and comprise a first link and a second link. The method comprises the steps of performing link flow statistics on the first link and the second link according to a preset period, judging whether the first link and / or the second link are / is required to be subject to bandwidth adjustment according to results of the link flow statistics, and adjusting the bandwidth of the first link and / or the second link when the bandwidth adjusting method is allowed if the bandwidth adjustment is required. By adopting the scheme, the bandwidth distribution proportion of each link shared by each load on a VPN (Virtual Private Network) HQoS network side can be controlled according to the practical demand of an operator, and bandwidth distribution can be dynamically adjusted according to the requirement of communication equipment, so that the method has more flexibility.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a link bandwidth adjustment method and device. Background technique [0002] In the VPN (Virtual Private Network, Virtual Private Network) networking, multiple tunnels can be established between PEs (Provider Edge, operator edge equipment), and the data flow for communication between the two nodes PE1 and PE2 includes: 1) entering Traffic of various tunnels, including VPN traffic and non-VPN traffic. 2) Public network IP traffic that does not enter the tunnel. Bandwidth preemption is prone to occur between these different types of traffic. [0003] In order to meet the requirements of service quality, it is necessary to limit the bandwidth of different traffic, so as to ensure that various services can be allocated to the predetermined bandwidth. The VPN HQoS (Hierarchical Quality of Service) feature can specify network-side bandwidth guarantee and bandwidth lim...
