Abstract

The invention provides address allocation methods and device. The method and the device are applied to a controller in VXLAN (Virtual eXtensible LAN) networking. A method comprises the steps of issuing a processing rule for a current IP address if it is determined that the current IP address of target user equipment is attacked by traffic, thereby enabling traffic of which destination address is the current IP address is discarded and determining a new IP address for the target user equipment; and sending the new IP address to the target user equipment according to a received address obtainingrequest sent by the target user equipment. Through application of the design, business of the target user equipment can be operated normally.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular, to an address allocation method and device. Background technique [0002] VXLAN (VirtualeXtensible LAN, scalable virtual local area network) is based on IP (Internet Protocol, Internet Protocol) network, using "MAC (Mediaor Medium Access Control, Media Access Control) in UDP (UserDatagram Protocol, User Datagram Protocol)" encapsulation form Layer 2 VPN (Virtual Private Network, virtual private network) technology. Based on the existing service provider or enterprise IP network, VXLAN can provide Layer 2 interconnection for dispersed physical sites and provide service isolation for different tenants. [0003] In a VXLAN networking, an IP address is assigned to an authenticated user device. However, the IP address may be attacked by traffic during use, resulting in the occupation of a large amount of resources on the user device. [0004] At present, in view of...
