Problems solved by technology

However, IP addresses are configured separately for all switches, and the management network connection cannot be realized until all IP addresses of all switches are configured, which leads to high configuration complexity and difficult deployment of the switch management network.

Abstract

The invention provides an SDN controller in-band management connecting method and an SDN controller in-band management connecting device. The SDN controller in-band management connecting method comprises steps that an SDN controller is used to transmit an initial connection message to a switch connected with a port in an on-line state; an initial connection response message transmitted by the switch is received by at least one port in the on-line state, and comprises the network interconnection protocol IP address of the switch used for transmitting the initial connection response message; a new IP address is allocated to the switch having the IP address, which is a default IP address; an address configuration message is transmitted to the switch provided with the IP address by the port used for receiving the initial connection response message, and the switch used for receiving the address configuration message is used to replace the IP address by the IP address of the address configuration message. The SDN controller is quickly and actively connected with the switch, and is used for allocating the IP address, and therefore the configuration complexity and the deployment difficulty of the management network of the SDN switch are reduced.

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...
