Method, device and system for accessing VPC (virtual private cloud) to VPN (virtual private network)

Abstract

The embodiment of the invention discloses method, device and system for accessing a VPC (virtual private cloud) to a VPN (virtual private network), and the data center exit gateway comprises the following steps: receiving first configuration information which comprises parameter information of a VPC, identifying information of a VPN, and address information of a network side PE (provider edge); establishing a first VPN living example according to the identifying information of the VPN; determining the VPC according to the parameter information of the VPC and binding the VPC and the first VPN living example; and sending second configuration information to the network side PE according to the address information of the network side PE, wherein the second configuration information comprises identifying information of the VPN, so as to enable the network side PE to be configured with an upper layer of VPN living example of the first VPN living example on the network side PE according to the identifying information of the VPN. The embodiment of the invention solves the problem of automatically accessing the VPC to the VPN.

Description

technical field [0001] The present invention relates to the field of data communication, in particular to a method, device and system for accessing a virtual private cloud to a virtual private network. Background technique [0002] With the popularity of data centers, users no longer need to purchase equipment and arrange their own IT centers. Users can apply for a group of IT resources in the data center to provide themselves with cloud computing services, and the IT resources are managed by the data center. The hardware resources in the data center provide users with cloud services in the form of virtualized devices. For example, if an enterprise applies for N servers, the data center will not physically divide N servers for users, but according to the user's requirements for the server, such as CPU , memory, hard disk size and other requirements, virtualize N servers in hardware resources for enterprises to use. These virtual servers, that is, resources requested by use...

Problems solved by technology

The existing HoVPN VPC access method can only manually create the upper-layer VPN instance and the first VPN instance on the network side PE and the data center gateway respectively by the operator. When the VPC is dynamically created and revoked, the binding between the VPC and the VPN The fixed relationship may also change dynamically, so using the existing VPC access method of manually setting the HoVPN method, the time cost and economic cost will be very high. The present invention provides a method for automatic VPC access and withdrawal of the HoVPN method
