11.3 The interfaces between the bDDN control domains

Figure 11-6 – The DDI interfaces

The reference model of bDDN is shown in Figure 8-1. It is recommended that big-data-driven networking has
a domain-domain interface which defines the interface between the different bDDN control domains.
In carrier-grade networks, there are many carriers and vendors, and each vendor may have their own bDDN
control cube. The bDDN control cubes in different domains need to communicate and negotiate with each
other. So, we need a clear definition of the interface between bDDN control domains.

The DDI interface will exchange the data and signalling with other domains. The big data plane in different
domains need to communicate with each other. The control cube communication network can be in-band
by using embedded communication channels. Also, the control cube communication network can be out-of-
band by using additional communication channels.

12 Security considerations
When using big-data-driven networking security best practices should be adopted such as authentication,
authorization and access control.
