Method and apparatus of data-centric networking with Network nodes

摘要

The present invention relates to a network system, and more particularly, to a networking method for performing functional data processing in a data-centric network system for supporting both pull and push modes. The network system of the present invention comprises a user terminal and a network node for performing the functional data processing. To this end, the data networking method in a data-centric network system of the present invention comprises the steps of: receiving a message including context meta information corresponding to function processing; analyzing a function name and the context meta information to perform filtering for each functional element utilized in a context filtering table (CFT); and performing the function processing designated for content including the filtered functional element. According to an embodiment of the present invention, the function processing for data can be requested by needs of a data requester or a data user, and also, and a data creator can designate a processing function for the data even in case of data distribution, thereby securing sovereignty of the data creator.
