A centralized control and programmable information center network design method

Abstract

The invention discloses a centralized control and programmable information center network design method, which decouples the control plane and the data plane of the information center network, and realizes the connection between the control plane and the data plane through an open interface. The data plane is composed of physical network devices, providing identification and forwarding of data flow, monitoring and statistics of data information, and in-network caching. The control plane is composed of a programmable and logic-centralized controller. The controller has the function of the control plane of the information center network, and realizes content naming, routing, data security and cache management. The centrally controlled and programmable information center network of the present invention has the characteristics of abstraction of the data plane and programmable control plane.

Description

technical field [0001] The invention belongs to the field of computer network architecture, and relates to a centralized control programmable information centric network (CPICN) that combines the advantages of centralized control of software-defined networks and the advantages of accelerated content distribution of information centric networks design method. Background technique [0002] With the popularity of social networks, cloud storage, video websites, and data applications, the Internet has shown a content-centric development trend. According to the forecast of Cisco Virtual Network Index, various forms of multimedia traffic will reach 90% of network traffic by 2018. The use of the network has seriously deviated from the existing network design principles and assumptions. Performance, reliability, availability, scalability, etc. are facing great challenges. [0003] Information Centric Network (ICN) is a new type of architecture that can meet the needs of users for i...

Problems solved by technology

It has the following disadvantages: it cannot give full play to all the advantages of the information center network. The information center network router is designed and implemented for the content-centered goal, while the Openflow switch is designed and implemented with the location as the center; it cannot realize the information center network data plane and Thorough decoupling of the control plane. The above solutions only realize the functions of the information center network from the perspective of software-defined networks, and cannot fully realize the independence of the control plane of the information center network.
