Method and device for realizing linkage between cloud management server and SDN (Software Defined Network)

Abstract

The invention provides a method and a device for realizing linkage between a cloud management server and an SDN (Software Defined Network). The method comprises the following steps: receiving a configuration instruction of the SDN from the cloud management server; creating an HTTP session communicating with a controller of an SDN, and obtaining current configuration information of the SDN; processing the current configuration information according to the configuration instruction to obtain user configuration information, wherein the configuration instruction comprises configuration query, configuration addition and configuration deletion; feeding back a processing result of the configuration instruction to the cloud management server; and when the processing is successful, transmitting the user configuration information to the controller. According to the invention, the problem that the cloud network linkage capability of the Sink SDN system of the Openstack enterprise private cloud under the heterogeneous virtualization framework is insufficient is solved, the configuration concept and configuration steps of the Sink SDN network are simplified, and the driver layer docking between the cloud management platform and the Sink APIC controller is realized.

Description

technical field [0001] The present invention relates to private cloud technology, in particular to a method and device for implementing linkage between a cloud management server and SDN. Background technique [0002] At present, the industry realizes the linkage technology between the private cloud of the Openstack framework and the software-defined network (Software Defined Network, referred to as SDN), mainly through the Neutron component of the Openstack framework and Cisco's SDN switch Advanced Programmable Interrupt Controller (Advanced Programmable Interrupt Controller, referred to as The APIC-ML2-driver driver interface implementation of the ML2 (Module Layer 2) model between APIC), and can only support the docking of KVM (Keyboard Video Mouse) virtualization; other virtualization technologies, such as: VMWare vSphere, PowerVM, FusionSphere, etc. , does not support the cloud-network linkage and automatic configuration functions of the second-tier network and the third...

Problems solved by technology

[0002]Currently, the linkage technology between private cloud and software-defined network (Software Defined Network, referred to as SDN) in the Openstack framework is realized mainly through the Neutron component of the Openstack framework and Cisco's The APIC-ML2-driver driver interface of the ML2 (Module Layer 2) model between the SDN switch Advanced Programmable Interrupt Controller (APIC) is realized, and it can only support the docking of KVM (Keyboard Video Mouse) virtualization ;Other virtualization technologies, such as VMWare vSphere, PowerVM, FusionSphere, etc., do not support the cloud-network linkage and automatic configuration functions of Layer 2 and Layer 3 networks. The network administrator manually configures the Cisco SDN controller APIC to passively meet the needs of the cloud network, which is inefficient and error-prone
