Embodiment Construction

[0050] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0051] In order to realize the automatic deployment of the IP address of the VM, the embodiment of the present invention deploys the DHCP Client on the VM, and deploys the DHCP Server on the controller; when implementing VM deployment during the SDN configuration process, the controller and the VM are exchanged via SDN The device realizes that the controller automatically allocates an IP address for the VM deployed in the SDN based on the interaction of the Dynamic Host Configuration Protocol (Dynamic Host Configuration Protocol, DHCP) message.

[0052] Among them, DHCP is a network protocol of the local area network. DHCP is based on the working mode of Client / Server. The basic working process of DHCP is as follows: figure 2 As shown, it mainly includes:

[0053] Step 201, the host client (Client) sends a DHCP Dis...

Abstract

The invention discloses a method and device for allocating IP addresses to virtual machines in a software defined network. Corresponding relations between virtual ports of the virtual machines (VM) and virtual machine MAC addresses and the IP addresses are configured in a controller. After SDN switching equipment is started, a DHCP message, issued by the controller and sent by each VM, is received and saved in a flow table of the controller. When receiving the DHCP messages sent by the VMs, the SDN switching equipment sends the DHCP messages to the controller after matching the DHCP messages with the flow table; when receiving the DHCP messages issued by the controller to the SDN switching equipment, the SDN switching equipment forwards the DHCP messages issued by the controller to the VMs. Each DHCP message issued by the controller contains the request that the controller allocate the IP addresses to the virtual machines according to the configured corresponding relations between the virtual ports and the virtual machine MAC addresses and the IP addresses.

Description

technical field [0001] The present invention relates to the field of software-defined networks, in particular to a method and device for allocating virtual machine IP addresses in a software-defined network. Background technique [0002] Software Defined Networks (Software Defined Networks, SDN) is a new network innovation architecture, its core technology is to realize the flexible control of network traffic by separating the control plane of network equipment from the data plane, and provide core network and application Innovation provides a good platform. In a traditional network, each switch or router needs to independently calculate the forwarding path of the message, while in the SDN network, the network device is only responsible for simple data forwarding, and the control part is independently a centralized controller, responsible for Different business logic and forwarding methods are used for control. An open and programmable interface is provided between the con...
