Abstract

The invention discloses a software defined network controller system in named data networking and a method thereof. A control plane and a data plane of the named data networking are separated by the system. The software defined network controller system comprises a storage module which is used for storing the data plane and maintaining four data structures of the data plane including a topological structure, a rule table, a push table and a routing table, wherein the control plane utilizes the data structures to control forwarding of data flow in the named data networking; a communication module which utilizes a customized communication format to establish connection between a software defined network controller of the control plane and network equipment of the data plane, maintain connection and receive and process data flow transmitted by the named data networking; and a function module API which is used for packaging functions of the storage module and is utilized to operate the storage module by an application layer so that direction of data flow is controlled.

Description

technical field [0001] The invention relates to a named data network, in particular to a software-defined network controller system and method used in the named data network. Background technique [0002] Information-Centric Networking (ICN) is a new type of Internet architecture model, which aims to fundamentally solve the problems of traffic scalability, content security and node mobility faced by the current Internet. Among them, Named Data Networking (NDN) is the most representative network model. The thin waist of the NDN architecture model is no longer the network address, but the data with a name. In the NDN data network, each content is given a unique name. When users obtain content, they do not need to inquire about the location of the content in advance, but directly express it with the name of the content. The biggest advantage of the NDN data network is that it can cache content, thereby greatly increasing the efficiency of information transmission; at the same ...
