A data source parsing method in information center network icn

Abstract

The invention relates to an information-centric networking ICN data source parsing method which adopts a registration-discovery mechanism that when a node stores target content or a server generates content, a parsing server requires to be informed; and an Interest query data source parsing system can obtain the position of all the data sources of the target content by utilizing a BloomFilter technology. The designed data source parsing system is self-adaptive with reference to the Q-learning idea. A storage mechanism preliminarily confirms commitment time of storage content, and registration is performed if commitment time is greater than the lowest threshold and the level of commitment time in the parsing system is confirmed; or registration is not performed. Meanwhile, the phase of the life cycle of the target content requested to be parsed is speculated by utilizing the number and change trend of the target content requested to be parsed and received by the parsing system so as to assist updating of name level in the parsing system and content storage commitment time. Effective data sources can be rapidly discovered from the ICN with existence of multiple data sources, and support of the ICN to mobility can be further enhanced.

Description

technical field [0001] The invention relates to a data source analysis method in an information center network ICN. Background technique [0002] In order to fundamentally solve the problems existing in the current Internet in terms of mobility support, scalability, security and controllability, it has gradually become the consensus of researchers to design a new future Internet architecture. In recent years, foreign countries have launched various research projects on the design of the new future Internet, and my country has also launched two 973 plan projects, and various new architectures have been proposed. [0003] Among them, Information-Centric Networking (ICN) is a general term for various information-centric architectures, which has an information-centric communication mode, an information distribution mode based on the entire network cache, and inherently supports mobility. , Internal security mechanism and so on. [0004] At the same time, according to statistic...

Problems solved by technology

[0005] At present, the main methods to deal with the above-mentioned demand challenges are P2P and CDN (Content Distribution Networks) based on the overlay network, but they are all at the application layer, and will encounter logical topology and physical topology mismatch, pre-planning and actual dynamic demand mismatch, etc. question
