Figure 9-1 – The module architecture of bDDN

Specifically, bDDN is composed of three planes, and each plane is composed of several layers. The big data
plane is composed of four layers. The bottom lays the data sensing layer, which, with the help of DPI and
other technologies, collects various data (including traffic data, network device performance data, network
management data and operation data, etc.) from the network scientifically. The big data plane also collects
some external circumstance data that may have an impact on networks. Such large real-time and inclusive
