System and method for implementing ipv6 flexible deployment through vxlan technology

Abstract

The invention discloses a system and method for realizing IPv6 flexible deployment through VxLan technology based on an SDN framework, and relates to the field of VxLAN adopted by a data center. The SDN controller of the system includes SDN OpenFlow interface module, intercommunication domain management module, topology management module, ARP / NS / NA processing module and IPV4 / IPv6 processing module; VxLANGateway includes configuration management module, VxLAN OpenFlow interface module, flow table management module , IPv4 / IPv6 tunnel encapsulation module, IPv4 / IPv6 tunnel decapsulation module and VxLAN transceiver module; VLAN switch includes VLAN transceiver module and VLAN ID module. The present invention can respectively deploy different network services on the same device, not only can ensure the continuity of the service, is more flexible, but also has lower requirements on the performance of the device, less delay, and relatively simple configuration and maintenance.

Description

technical field [0001] The present invention relates to the field of VxLAN (Virtual extensible LAN, virtual extensible local area network) adopted by the data center, and in particular to a method based on the SDN (Software Defined Network, software defined network) framework to implement IPv6 (Internet Protocol Version 6, Internet Protocol version 6) through VxLan technology. 6) A system and method for flexible deployment. Background technique [0002] SDN is a new network innovation architecture of Emulex network. SDN can efficiently separate network data flow processing from control data flow logic and rules, so that operators and enterprises can control and manage their own data and realize routing of different rules. (e.g. deciding which types of data are processed locally and which are processed remotely). Essentially, SDN gives organizations granular visibility and control over access to networks and resources, allowing IT managers to troubleshoot specific issues aff...

AI Technical Summary

Problems solved by technology

[0005] (1) Both LAFT6 and DS-Lite need to be deployed on the user side and the network side respectively, and cannot be changed arbitrarily after the equipment is deployed, which will lead to the fixed deployment of IPv6, which is not convenient for users to use

[0006] (2) Both DS-lite and LAFT6 technologies require NAT (Network Address Translation, Network Address Translation) technology. The use of NAT technology will result in end-to-end transparency, and the device needs to use a large-capacity flow table. Not only for the device The performance requirements are high, and the delay is large, and the configuration and maintenance are more complicated
