Abstract

The invention provides a network configuration method and device. The method is applied to the controller of an SDN (software defined network) and comprises receiving at least one DHCP (dynamic host configuration protocol) discovery message transmitted by a switch to be configured, wherein the DHCP message carries a request identity; for the firstly-receiving DHCP discovery message in the at least one DHCP discovery message transmitted by the switch to be configured, processing the firstly-received DHCP discovery message according to the request identity, and distributing an IP (Internet protocol) address for the switch to be configured; transmitting a DHCP providing message containing the IP address and the address of the controller to the switch to be configured so that the switch to be configured performs network configuration according to the IP address and the controller address, which are carried by the DHCP providing message. Therefore, the network configuration method is high in configuration efficiency and less prone to configuration errors, improves the working efficiency and reduces the operation and maintenance cost.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for network configuration. Background technique [0002] With the development of communication technology, the most popular software-defined network (Software Defined Network, SDN) technology is the OpenFlow protocol. Among them, OpenFlow is a communication interface standard between the controller and the forwarding layer defined in the SDN architecture. OpenFlow switches and controllers that support OpenFlow forwarding form an OpenFlow network. Wherein, a secure channel is established between the OpenFlow switch and the controller in the OpenFlow network through a transport layer security protocol (Transport Layer Security, TLS) or a transmission control protocol (Transmission Control Protocol, TCP), and the secure channel is used to exchange OpenFlow messages . [0003] When an OpenFlow switch is newly added in the OpenFlow network, the OpenFlow s...
