Problems solved by technology

[0006] This solution can realize the function of virtualized network devices, but the number of network cards is fixed and cannot be changed. If there are only differences in the number of interfaces between different switches, it is still necessary to make a mirror with different numbers of network cards. Increased the workload of mirroring, and for the management of platform mirroring, storage provides pressure

Embodiment Construction

[0032] A method for dynamically managing network interfaces of cloud hosts according to the present invention will be further described in more detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, a dynamic management method of a cloud host network interface includes the following steps:

[0034] 1) The method of adding a network interface when creating a cloud host has the following steps:

[0035] 11) Provide a basic image with ovs and cloud-init software installed;

[0036] 12) The provided openstack environment is deployed with metadata service, and the cloud host can obtain customized information through metadata;

[0037] 13) When creating a cloud host, provide a script to set the number, name, mac address and ovs of the cloud host interface and add the network interface to the bridge. This script modifies the system file / etc / udev / rules.d / 70-persistent-net. rules, associate the network interface name with the mac address, an...

Abstract

The invention discloses a dynamic management method for a cloud mainframe network interface. A cloud mainframe is used for supplying the functions of network equipment such as a virtual switch and a virtual router in a network analog simulation experiment platform and is capable of dynamically adding or deleting interfaces, maintaining the corresponding relation of mac address, network card name and virtual switch port number, maintaining correct network configuration, reducing the pressure of mirror image preparation, management and storage and improving the working efficiency. Compared with the prior scheme, the dynamic management method for the cloud mainframe network interface disclosed by the invention has the advantages that openstack metadata service and file injection are utilized to customize the cloud mainframe network interface, the effects of mirror image file reuse and dynamic management for the cloud mainframe interface are achieved and the method can meet the flexible management requirement of the virtual network equipment for the interfaces.

Description

technical field [0001] The invention belongs to the technical field of cloud hosts, in particular to a method for dynamically managing network interfaces of cloud hosts. Background technique [0002] The current network architecture is undergoing fundamental changes, from the first generation of analog communication, to the second generation of digital communication, to the third generation of the Internet, SDN / NFV is the fourth network revolution, which has led the academic community to be able to support network architecture verification The urgent need of the network experiment system. However, building a network experiment system directly based on physical facilities requires a large amount of capital investment, and the experimental network is tightly coupled with physical hardware, which is not conducive to the diversification of experimental requirements and the sharing of experimental resources. There are low resource utilization, high experimental thresholds, and di...
