Problems solved by technology

[0004] Hose VPN maximizes the utilization of network resources for the provider, but for the user, when the Hose hose bandwidth rented by the user is large, because the user does not transmit a large amount of data at any time, resulting in Waste of user VPN network resources; when the bandwidth of the Hose hose rented by the user is small, and when the user needs to transmit a large amount of data, the VPN cannot meet the user's needs

Embodiment Construction

[0052] Given a Hose-based VPN such as figure 1 As shown in the figure, assume that CE1, CE2, and CE3 belong to the same VPN and are connected to PE1, PE2, and PE3 of the provider network through Hose1, Hose2, and Hose3 respectively; the routes and algorithms of PE1, PE2, and PE3 in the provider network are not considered. In the middle; currently in the default state, the uplink and downlink bandwidth of the Hose hose is determined, and the provider network ensures the user’s Hose hose uplink and downlink data transmission, and optimizes the bandwidth resources between PE1, PE2, and PE3; Hose1, Hose2, and Hose3 can be The increased uplink and downlink bandwidth capacity is 20M; assume the threshold value B for bandwidth adjustment th is 1M.

[0053] We assume that the sending data control unit in the CE1 user bandwidth control unit detects that a large amount of data needs to be sent to CE2 and CE3, and it is necessary to increase the bandwidth capacity of 10M and 8M to CE2 a...

Abstract

The invention discloses a virtual private network (VPN) customer broadband control method based on Hose technology, which adds a customer broadband control unit at a customer edge (CE). The method is characterized in that the control unit comprises a data transmitting control unit and a data receiving control unit; the data transmitting control unit detects the bandwidth required for data transmission, sends a bandwidth querying message, a bandwidth adjustment application message and a bandwidth control message and modifies the data transmission bandwidth of a hose, and the data transmitting control unit has a timer mode, a transmission bandwidth increase mode and a transmission bandwidth decrease mode; the data receiving control unit detects the current data flow of the hose, sends a bandwidth control message and modifies the data reception bandwidth of the hose, and the data receiving control unit has a timer mode, a reception bandwidth decrease mode and a reception bandwidth increase mode. The method not only satisfies the customer's demands, but also minimizes the usage of the network resources provided by providers, so as to save network resources.

Description

technical field [0001] The present invention relates to a virtual private network based on a Hose hose, in particular to a user broadband control method based on a Hose hose VPN (Virtual Private Network, virtual private network). Background technique [0002] With the continuous development of the network, VPN has gradually become the focus of attention. The traditional VPN model adopts the point-to-point user pipeline technology, and a point-to-point link must be established between each pair of VPN users that need to exchange data, and finally a grid is formed. The disadvantage of this technology is that users need to know the traffic matrix of all endpoints in detail, and the pipes used by users cannot be reused, resulting in a serious waste of network resources. [0003] Hose-based VPN model such as figure 1 As shown, the user end and the provider network are connected by Hose hose. The core idea of ​​the hose technology is that the hose bandwidth between the user and...
