Embodiment 1

[0039] as attached figure 1 As shown, in the public cloud platform based on openstack of the present invention, realize the VPC peer-to-peer connection method and system, the steps are as follows:

[0040] S1. Establish two VPCs to be connected: the two VPCs to be connected are recorded as VPC A and VPC B respectively, and the subnet addresses of VPC A and VPC B do not overlap each other;

[0041] S2. Establish a VPC connector to realize the interconnection of two VPCs: the VPC connector includes two networks and a connector connector, and the connector connector is a vrouter to realize routing and forwarding; the two networks are respectively recorded as network C and network D, network C and network D is a large two-layer network, and data packets under the same network realize two-layer forwarding;

[0042] S3. Establish a subnet of network C: establish a subnet in network C, and hang the subnet on the qrouter of VPC A and the connector vrouter at the same time;

[0043] ...

Embodiment 2

[0051] as attached figure 2 As shown, the VPC peer-to-peer connection system is realized in the public cloud platform based on openstack of the present invention, and the system includes a northbound interface module, a VPC connector management module, a routing table management module, a VPC interconnection database and an openstack cloud computing management platform; a northbound interface module The VPC connector management module and the routing table management module are respectively connected, the VPC connector management module is respectively connected to the VPC interconnection database and the openstack cloud computing management platform, and the routing table management module is respectively connected to the VPC interconnection database and the openstack cloud computing management platform. Northbound interface module The northbound interface module is used to provide the interface for the operation and management platform to manage VPC interconnection (that is,...

Embodiment 3

[0056] prerequisites:

[0057] Currently, there are two subnets subnetA (10.10.10.0 / 24) and subnetB (20.20.20.0 / 24) in VPC A and VPC B respectively. The router of VPC A is qrouterA, and the router of VPC B is qrouterB. VPC connector includes two networks (network1, network2) and a connector vrouter; as attached image 3 As shown in , the specific steps for the peer-to-peer connection between VPC A and VPCB are as follows:

[0058] (A), call the northbound interface to create a VPC peering connection, subnetA and subnetB need to establish a connection;

[0059] (B). The northbound interface management module verifies whether the addresses of subnet A and subnet B overlap:

[0060] ①. If there is no overlap, write the relevant information of the peer-to-peer connection into the VPC interconnection database, and then perform step C);

[0061] ②, if overlapping, return an error message;

[0062] (C), The VPC connector management module establishes a subnet subnet1 (100.0.0.0 / ...

Abstract

The invention discloses a method and a system for achieving VPC peer-to-peer connection in a public cloud platform based on openstack, and belongs to the field of cloud computing and computer networks. The method aims to solve the technical problem of how to realize peer-to-peer connection of specified subnets in different VPCs, and adopts the technical scheme that the method comprises the following steps: S1, establishing two VPCs needing to be connected; S2, establishing a VPC connector to realize the interconnection of the two VPCs: the VPC connector comprising two network and a connector,the connector being a vrouter, and realizing the routing forwarding; wherein the two networks are respectively marked as a network C and a network D, both the network C and the network D are large two-layer networks, and two-layer forwarding of data packets under the same network is realized; S3, establishing a subnet of the network C; S4, establishing a subnet of the network D; S5, adding a static route; and S6, interconnecting and intercommunicating the two VPC subnets. The system comprises a northbound interface module, a VPC controller management module, a routing table management module,a VPC interconnection database and an openstack cloud computing management platform.

Description

technical field [0001] The invention relates to the field of cloud computing and computer network, in particular to a method and system for realizing VPC peer-to-peer connection in an openstack-based public cloud platform. Background technique [0002] Cloud computing is one of the hottest topics in the field of IT infrastructure in recent years. Its virtual abstraction of computing, network, storage and other resources provides users with extremely convenient resource usage and flexible resource expansion capabilities. VPC (Virtual Private Cloud) is a custom logically isolated network space on the public cloud, and it is a network space that we can customize. The VPC is completely isolated from the VPC, thus ensuring the logical isolation of I2. Tenants can flexibly customize the network environment, and customize subnet segments, routing tables, etc. Multiple subnets can be established in a VPC, and tenant virtual machines in the same VPC can communicate with each other,...
