IPv6 route announcement method based on SDN and system

Abstract

The invention relates to an IPv6 route announcement method based on an SDN and a system thereof. The IPv6 route announcement method based on the SDN comprises the following steps: acquiring a first route announcement data packet; modifying at least one piece of field information of the first routing data packet to assemble a second routing announcement data packet; and forwarding the second routing announcement data packet to a cloud host through an SDN switch. According to the IPv6 route announcement method based on the SDN and the system, the first route announcement data packet is obtained;the IPv6 routing announcement message data packet is packaged in a self-defined manner, the field information in the first routing announcement data packet is modified to form the second routing announcement data packet, the self-defined packaging of the IPv6 routing announcement message data packet is realized, more comprehensive data configuration is provided, the networking logic of the cloudVPC is fused, and the automatic construction of the cloud network is responded.

Description

technical field [0001] The invention belongs to the technical field of data communication, and in particular relates to an SDN-based IPv6 route announcement method and system. Background technique [0002] In an IPv4 network, based on router discovery technology, hosts can locate routers and learn important parameters related to local network operations. In an IPv6 network, routers regularly multicast router advertisement messages to announce their availability and pass the information to adjacent nodes, so that hosts can be automatically configured on the network. [0003] Existing data centers generally deploy a physical router to implement related services. This method has at least the following problems: [0004] 1) The problem of single point of failure in traditional data centers and insufficient disaster recovery capabilities; [0005] 2) Considering the security of the routing announcement itself, relevant configuration is required, and the operation is cumbersome;...
