5 Big data - Concept and application for telecommunications

In a word, bDDN is a type of future network framework that provides big data service and network
intelligence to facilitate smarter network management, operation, control, optimization and security, etc.
based on the big data generated by the network itself.

To express the differing scopes of big data collection and/or administrative/control responsibilities, we
introduce the domain notion in bDDN. A bDDN control domain thus represents a collection of entities that
are grouped for a bDDN control and data collection purpose. A bDDN control domain is comprised of a
collection of network infrastructure components, and components in a bDDN control cube. One component
in the network infrastructure can only belong to one domain. The big data plane only collects the data of the
component in this domain. The management plane only manages the nodes of the domain, and the control
plane is only responsible for the nodes of this domain.
The data exchange between the bDDN control domains is defined by the domain-domain interface (DDI). The
DDI is defined in the following clause.
Each domain of bDDN corresponds to a bDDN control cube. It is generally based on the cloud architecture,
responsible for big data collection, processing, computing and network control and management. The bDDN
control cube constitutes the control centre of the bDDN network.
The bDDN control cube is composed of a data plane, network plane and management plane; the relationship
between the three planes is as follows:
