Abstract

Embodiments of the present invention provide a connection method and device for in-band management of an SDN controller, the method comprising: the SDN controller sends an initial connection message to a switch connected to an online port; The port receives the initial connection reply message sent by the switch, wherein the initial connection reply message includes the network interconnection protocol IP address of the switch that sends the initial connection reply message; assigns a new IP address for the switch whose IP address is the default IP address; Send an address configuration message to the switch that has been assigned an IP address through the port that receives the initial connection reply message, so that the switch that receives the address configuration message configures the IP address as the IP address in the address configuration message. The application of the embodiment of the present invention can realize that the SDN controller actively and quickly connects to the switch and assigns an IP address, and can reduce the configuration complexity and deployment difficulty of the management network of the SDN switch.

Description

technical field [0001] The invention relates to the field of network management, in particular to a connection method and device for in-band management of an SDN controller. Background technique [0002] Software Defined Network (Software Defined Network, SDN) is a new type of network architecture and a way to realize network virtualization. Its core technology, the new network switching model OpenFlow, separates the control plane and data plane of network equipment, thereby It realizes the flexible control of network traffic and makes the network more intelligent as a pipeline. [0003] The SDN controller and multiple SDN switches form a network. There is a physical connection between the port of the SDN controller and the switch, and between the switch and the switch. The SDN controller forms the management network of the SDN switch through the physical connection with all the switches in the network. The SDN controller connects the SDN switch through the management netwo...
