Communication method and device based on software-defined network and integrated identification network

Abstract

The invention discloses a communication method and device based on a software-defined network and an integrated identification network, belonging to the field of network technology. The method includes: when the controller has established a connection with the access forwarding device, receiving the device information of the access forwarding device; generating the whole network topology according to the device information of each connected access forwarding device; , generate a routing table; send the routing table to the access forwarding device, so that when the access forwarding device receives the data packet, it queries the routing table according to the destination routing identifier of the data packet, determines the forwarding path, and forwards the data based on the destination routing identifier and the forwarding path Bag. The present invention separates the control plane from the data plane by introducing a controller into the integrated identification network, and does not need the access and forwarding equipment to run the routing protocol, which reduces the amount of calculation, saves time, improves query efficiency, and realizes full Flexible control of the network.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a communication method and device based on a software-defined network and an integrated identification network. Background technique [0002] The traditional Internet is designed for fixed terminals, and IP (Internet Protocol, Internet Protocol) addresses can be used to represent attributes such as the identity and location of fixed terminal users at the same time. However, with the increasing scale of the Internet and the popularity of mobile terminals, IP addresses The dual properties of the routing cause scalability issues, mobility issues, security issues and many other issues. Therefore, the system structure of the integrated identification network is proposed, and the concepts of access identification and routing identification are introduced. The access identification is used in the access network to represent the identity of the user, and the routing identificati...

Problems solved by technology

[0004] In the process of running the routing protocol, each access forwarding device can only obtain the routing information of the adjacent access forwarding device. When looking for the forwarding path between the destination access forwarding device, it is necessary to obtain the adjacent routing information level by level. Accessing the device information of the forwarding device until the device information of the destination accessing forwarding device is obtained, the calculation is very heavy, it takes too much time, and the query efficiency is very low
