Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] Software-defined network (SDN) is a network that realizes network forwarding function through software programming. In this network, the control and forwarding of the network are separated, and the controller controls the forwarding of the network. Participation is only to forward traffic according to the decision of the controller, so that the network becomes more flexible and controllable.

[0026] Dynamic Host Configuration Protocol (DHCP) is used to automatically assign IP addresses and other information to hosts in a LAN. In this process, the messages between the client (host) and the DHCP server mainly include DHCP DISCOVER messages, DHCP OFFER messages, DHCP REQUEST messages, DHCP ACK ...

Abstract

The invention provides a network configuration method and apparatus. The network configuration method includes the following steps: after a controller monitors that a message is found in a dynamic host configuration protocol sent from a virtual machine in a subnet, the controller packages the parameter configuration information corresponding to the subnet into a dynamic host configuration protocol supply message and sends the dynamic host configuration protocol supply message to the virtual machine; and after the virtual machine receives a dynamic host configuration protocol determination message sent from the controller, the virtual machine acquires the parameter configuration information and performs parameter configuration according to the parameter configuration information. In the technical scheme of the network configuration method and apparatus, by packaging the parameter configuration information into the host configuration protocol supply message through the controller, the network configuration method and apparatus can realize parameter automatic configuration of the virtual machine in the subnet, thus improving the parameter configuration efficiency, and reducing the parameter configuration error probability.

Description

technical field [0001] The invention belongs to the technical field of cloud computing, and in particular relates to a network configuration method, device and controller. Background technique [0002] With the application of cloud computing more and more widely, SDN (Software-defined networking, software-defined network) with its three characteristics of "separation of control plane and forwarding plane", "device resource virtualization" and "hardware and software programmable" , making it more and more widely used in cloud computing, followed by SDN network administrators also have to face tedious and repetitive network configuration work for virtual machines and other devices in the SDN network. [0003] The aforementioned method of manually configuring the network reduces configuration efficiency on the one hand, and makes the configuration process prone to errors on the other hand. [0004] Therefore, it is urgent to provide a network configuration solution to solve th...
