A virtual router and a method for realizing the interconnection between an SDN network and a traditional IP network

Abstract

The invention discloses a virtual router, which is characterized in that: it includes an SDN controller, a kernel module, and a protocol module; The text data is encapsulated by the OF protocol through the SDN controller module, and forwarded to the corresponding interface for processing; a standard southbound interface is provided to the lower side; the kernel module: shielding the bottom layer provides a standard IP layer and interface for the operation of the upper layer protocol; and Complete the communication adaptation between the IP core message and the SDN controller; the protocol module: for processing the traditional standard router protocol, forming a corresponding routing table and forwarding table, and notifying the SDN controller through the routing engine module, The SDN controller generates flow entries according to the routing table and forwarding table, and delivers them. The invention can realize the interconnection and communication between the SDN network and the traditional network.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a virtual router and a method for realizing interconnection between an SDN network and a traditional IP network. Background technique [0002] Traditional network devices are individually controlled on a device-by-device basis. Each device must perform not only the functions of the forwarding plane, but also the functions of the control plane and management plane. The networking is completed through interactive control signaling between devices. [0003] First of all, it is difficult to adjust and control resources from the perspective of the entire network in terms of network congestion control and service quality assurance in traditional networks; secondly, in terms of forwarding mode, traditional network equipment is basically fixed, that is, route selection and forwarding are performed according to the target IP address , it is impossible to carry out c...
