5 Big data - Concept and application for telecommunications

3.2.3 big-data plane: The big-data plane is the main part of bDDN. It is responsible for network big data
collection, storage and computation, and has powerful big data computing and analytical ability. It extracts
the useful information and intelligence from the network's big data. Then it provides network intelligence for
network management, operation, control, optimization and security, etc.

The term "is required to" indicates a requirement which must be strictly followed and from which no
deviation is permitted, if conformance to this Recommendation is to be claimed.

In the body of this Recommendation and its appendices, the words shall, shall not, should and may
sometimes appear, in which case they are to be interpreted, respectively as, is required to, is prohibited from,
is recommended, and can optionally. The appearance of such phrases or keywords in an appendix or in
material explicitly marked as informative are to be interpreted as having no normative intent.

6 Introduction
As the Internet becomes ubiquitous in its role as a social infrastructure, various Internet applications have
emerged, and the complexity of traffic carried over the telecommunication networks continues to increase.
We can obtain large amounts of traffic data based on deep packet inspection and operation data from the
telecommunication network management or operation entity, and how to use this data to obtain useful
information, thus improving the traffic and network management process is the problem that the operators
need to consider. Big data technology and machine learning are important technical trends in the industry.
The big data technology will be effective in handling traffic and network complexities, and big-data-driven
networking will propose to study the applying of big data analytics technologies and machine learning for
future networks.

7 Overview of big-data-driven networking

The big data generated by networks themselves implies a great deal of useful information for network
management, operation, control, optimization and security, etc. Such valuable and such a tremendous
amount of information, unfortunately, cannot be efficiently utilized by traditional network architecture.
