Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present application clearer, the solution of the present application will be further described in detail below with reference to the accompanying drawings.

[0034] like figure 1 As shown, it is a schematic diagram of an application scenario of an embodiment of the present invention, including a sub-DHCP server in the SDN network, a control device in the SDN network, a DHCP server for the control device, and multiple hosts, wherein the sub-DHCP server in the SDN network can be Multiple, the control device in the SDN network and the sub-DHCP server in the SDN network can communicate through messages, and the host can be a physically existing host or a virtual host (VM, Virtual Machine) (VM1 and VM2).

[0035] The invention provides an IP address allocation method to solve the problem in the prior art that the same IP address is allocated to different hosts and IP address allocation conflicts occur.

Abstract

The invention provides an IP address distribution method and device. The IP address distribution method includes the steps that a first finding message is sent, and the first finding message comprises a to-be-distributed IP address selected from an IP address pool of a DHCP server of control equipment for a mainframe; a distribution affirming message replied by a sub-DHCP server in an SDN network according to the first finding message; if it is affirmed according to the distribution affirming message that the to-be-distributed IP address is distributed by the sub-DHCP server, the state of the to-be-distributed IP address is updated, and a new IP address is selected for the mainframe again; if it is affirmed that the to-be-distributed IP address is not distributed, the to-be-distributed IP address is distributed to the mainframe. Thurs, the problem of conflict of IP address distribution is effectively solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an IP address allocation method and device. Background technique [0002] In the prior art, when a host is online in an SDN (Software Defined Network, software-defined network), the control device in the SDN network has two ways to assign an IP (Internet Protocol, Internet Protocol) address to the online host : The control device manually statically configures the IP address, or the control device obtains the IP address from a DHCP (Dynamic Host Configuration Protocol) server in the Layer 2 network, and configures it for the host. However, after manually statically configuring an IP address for an online host, other online hosts may still obtain the same IP address from the DHCP server in the Layer 2 network, resulting in conflicts in the assignment of IP addresses to different hosts in the network. Happening. Contents of the invention [0003] The invention provides an...
