Method and device for a virtual machine to access a network

Abstract

The embodiment of the present invention discloses a method and device for a virtual machine to access the network, which is applied to an SDN controller. The method includes: receiving the authentication request message sent by the virtual machine sent by the access device, The machine sends an identity request message; receives the first identity request response message including the first identity information and the second identity request response message including the first password information sent by the virtual machine sent by the access device; when the first password When the information is the same as the second password information corresponding to the first identity information stored in the preset database, it is determined that the virtual machine has passed the authentication; an IP address is assigned to the virtual machine, and the IP address is sent to the virtual machine through the access device, so that the virtual machine Access the network based on the IP address. By applying the embodiment of the present invention, the SDN controller can centrally control the access of the virtual machine to the network, thereby reducing the network construction cost.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for a virtual machine to access a network. Background technique [0002] like figure 1 As shown, the local area network may include: an SDN (Software Defined Network, software defined network) controller 100 , an authentication server 200 , an access device 300 and a virtual machine 400 . [0003] When the virtual machine 400 needs to access the network, the virtual machine 400 needs to send the authentication request message to the authentication server 200 through the access device 300; Sent to the SDN controller 100; the SDN controller 100 assigns an IP (Internet Protocol, Internet Protocol) address to the virtual machine 400 according to the address request message; like this, the virtual machine 400 can access the network according to the assigned IP address. [0004] It can be seen from the above that in the prior art, the access of virt...

Problems solved by technology

[0004] It can be seen from the above that in the prior art, the access of virtual machines to the network is controlled by two devices, the SDN controller and the authentication server, and the SDN controller cannot centrally control the access of virtual machines to the network, which increases the cost of network construction.
