Abstract

The invention discloses a software-defined network controller system in a named data network and a method thereof. The system separates the control plane and the data plane of the named data network. The software-defined network controller system includes: a storage module for storing The data plane maintains four data structures of the topological structure of the data plane, the rule table, the push table and the routing table. The control plane uses these data structures to control the forwarding of data streams in the named data network; the communication module uses self-defined communication The format establishes the connection between the software-defined network controller of the control plane and the network device of the data plane and maintains the connection, receives and processes the data stream sent by the named data network; the function module API is used to store the module Function encapsulation, the application layer uses the function module API to operate the storage module to control the direction of the data flow.

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 ...
