Embodiment Construction

[0043] The present invention will be further described in detail below in conjunction with specific preferred embodiments and accompanying drawings.

[0044] figure 1 It is a schematic diagram of the structure of the SDN-based IPv6 routing announcement system in proxy mode. Such as figure 1 As shown, the SDN-based IPv6 route announcement system is deployed on each computing node in proxy mode. Each computing node deploys an SDN switch and an SDN controller. The cloud host is connected to the SDN switch, the SDN switch is connected to the external network through the uplink port of the computing node, and the SDN controller is connected to the SDN switch.

[0045] In addition, a physical routing announcer is deployed on the physical network of the data center for unified routing announcement of the physical network of the data center. The cloud platform virtual network (NC) of the computing node is connected with the Ipv6 routing announcement service of the existing data ce...

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;...
