Automatic adaptation method for different physical service networks of private cloud system

Abstract

The invention provides an automatic adaptation method for different physical service networks of a private cloud system. The automatic adaptation method comprises the following steps: S1, selecting aplurality of physical network cards of a computing node and binding the physical network cards as logic network cards; S2, updating a network bridge and a network card configuration file of the computing node, and accessing the logic network card to a set physical service network; S3, updating a private cloud system network configuration file stored by the control node according to the updated network bridge and network card configuration file; S4, restarting and loading the updated network card and network bridge configuration file by the computing node, restarting and loading the updated private cloud system network configuration file by the control node, and updating a virtual network flow forwarding flow table of the computing node; and S5, configuring a virtual machine of the computing node according to the private cloud system network configuration file, and realizing login of the virtual machine to the set physical service network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an automatic adaptation method for different physical service networks used in a private cloud system. Background technique [0002] In the existing private cloud system based on Openstack, the network is divided into data network, management network, and external physical service network for the use of the network. figure 1 , figure 2 It is a schematic diagram of the deployment model of the interaction between two neutron-based virtual networks and physical service networks. [0003] in such as figure 1 In the deployment model shown, the computing nodes are used as the VXLAN subnet of the cloud platform, and the computing nodes are used to forward network data according to the rules of the flow table. The computing node includes a virtual machine VM inside a host operating system, a security group bridge, a virtual switch br-int1, and a virtual switch br-tun1. The vi...
