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 and belongs to the technical field of network. The method includes the following steps: a controller receives device information of access forwarding devices when establishing connection with the access forwarding devices; according to device information of each of connected access forwarding devices, an entire-network topological structure is formed; according to the entire-network topological structure, a routing table is formed; and the routing table is sent to the access forwarding devices so that the access forwarding devices inquire the routing table and determine forwarding routes according to target routing identifications of data packets when receiving the data packets and forward the data packets based on the target routing identifications and the forwarding routes. The method introduces a controller in the integrated identification network and separates a control plane and a data plane without operation of a routing protocol by the access forwarding devices so that calculation quantity is reduced, time is saved, query efficiency is improved and flexible control of a whole network is realized.

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
