Method and system for acquiring network segment ID

Abstract

The invention discloses a method and a system for acquiring a network segment ID. The method comprises: detecting a network segment ID used for indicating whether each network segment is used in a pre-established network segment ID array according to a preset bitmap rule, and determining a network segment ID indicating that the network segment is in an unused state, extracting a network segment interval corresponding to the network segment ID in the unused state, and storing the network segment interval in the unUsedSegments linked list. Through the above disclosed method, the network segmentID in the unused state is determined according to the bitmap rule, the network segment interval corresponding to the network segment ID in the unused state is extracted, and the value corresponding tothe network segment interval is prompted to the user, so that the user creates the network according to the provided value corresponding to the network segment interval, and the purpose of improvingthe network creation efficiency is achieved.

Description

technical field [0001] The present invention relates to the field of cloud technologies, and more specifically, to a method and system for obtaining network segment IDs. Background technique [0002] With the development of cloud technology, the Openstack cloud computing management platform is more and more widely used in various fields. Openstack is an open source cloud computing management platform project, which includes components such as computing, object storage, interface management, and authority management. [0003] When creating a virtual local area network VLAN or a virtual extended local area network VXLAN in the Openstack cloud computing management platform, you need to enter the corresponding network segment ID, that is, you need to enter a VLAN ID to create a VLAN network, and you need to enter a VXLAN ID to create a VXLAN network. Different VLAN networks or VXLAN networks , its VLAN ID or VXLAN ID is also different. [0004] In the prior art, the Openstack ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the Openstack cloud computing management platform does not provide an interface for querying available VLAN IDs and VXLAN IDs, so that the Openstack cloud computing management platform cannot be called to query which VLAN IDs or VXLAN IDs are not used, only unused VLAN IDs or The VXLAN ID can only be used when creating a network. The Openstack cloud computing management platform can only find the available VLAN ID or VXLAN ID by continuously trying to fill in the VLAN ID or VXLAN ID and then according to the prompt information of whether to use the ID fed back by the backend, thereby reducing the creation time. network efficiency
