Embodiment Construction

[0088] In the embodiment of the present invention, in the embodiment of the present invention, the virtual network function is used to design the SDN controller and the SDN switch, and the SDN controller and the SDN switch are used to send messages related to the control of transmission resources to the NFVM&O device, and the SDN controller according to the NFVM&O device The transmitted transmission resource control instruction carrying whether the specified transmission resource can be controlled controls the transmission resource, which improves the utilization rate of the transmission resource.

[0089] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present inventi...

Abstract

The invention discloses a method and equipment for controlling transmission resources in a software defined network SDN. A network function virtualization management and orchestration NFV M and O device receives a message related to control of the transmission resources sent by a SDN controller and / or a SDN switch; according to the received message related to control of the transmission resources, whether the SDN controller can control an appointed transmission resource or not can be determined; and a transmission resource control instruction carrying a definitive result is sent to the SDN controller. In the scheme in the embodiment of the invention, the message related to control of the transmission resources is sent to the NFV M and O device through the SDN controller and the SDN switch; the SDN controller controls the transmission resources of the SDN switch according to the transmission resource control instruction sent by the NFV M and O device; and thus, the utilization rate of the transmission resources is increased.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for controlling transmission resources in an SDN (Software Defined Network, software defined network). Background technique [0002] SDN technology migrates the control plane of switching equipment to a centralized controller to realize the separation of control and forwarding. The logical architecture of SDN defined by ONF (OpenNetwork Foundation, Open Network Foundation) is as follows: figure 1 shown. [0003] figure 1 In the logical architecture shown, there are application layer, control layer, and infrastructure layer from top to bottom; the interface between the application layer and the control layer is called the northbound interface, and the interface between the control layer and the infrastructure layer is called the northbound interface. It is a southbound interface; the application layer deploys various network applications wit...
