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 NFV M&O device. The transmission resource control instruction sent by the M&O device carries the transmission resource control instruction whether to control the specified transmission resource to control 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 invention...

Abstract

The invention discloses a method and equipment for controlling transmission resources in a software-defined network (SDN). Network function virtualization management and arrangement NFV M&O devices receive messages related to the control of transmission resources sent by SDN controllers and / or SDN switches; according to After receiving the message related to the control of the transmission resource, determine whether the SDN controller can control the specified transmission resource; and send a transmission resource control instruction carrying the determination result to the SDN controller. In the solution of the embodiment of the present invention, the SDN controller and the SDN switch are used to send messages related to the control of transmission resources to the NFV M&O device, and the SDN controller controls the transmission resources of the SDN switch according to the transmission resource control instruction sent by the NFV M&O device, The utilization rate of transmission resources is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and 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 (Open Network 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 application...
