IPM-PR the reference point between the policy management FE and the policy and rule translation FE.

The policy management FE sends registered policy rules in the local catalogue to the policy and rule
translation FE for further processing with this reference point.
IPC-TM the reference point between the policy creation FE and the topology management FE.
The policy creation FE receives topology information from the topology management FE with this
reference point.
ITM-TC the reference point between the topology management FE and the topology collection FE.

The topology collection FE sends the global topology information to the topology management FE
for further processing with this reference point.

ITC-PR the reference point between the topology collection FE and the policy and rule translation FE.
The topology collection FE collects topology information from the policy and rule translation FE with
this reference point.

ITM-TS the reference point between the topology management FE and the traffic scheduling and
optimization FE.

With this reference point, the topology management FE provides the global topology information
to the traffic scheduling and optimization FE, and obtains traffic optimization results from the traffic
scheduling and optimization FE.
ITS-TMO the reference point between the traffic scheduling and optimization FE and the traffic monitoring
FE.

The traffic scheduling and optimization FE retrieves the real time traffic load information from the
traffic monitoring FE with this reference point.

ITMO-PR the reference point between the traffic monitoring FE and the policy and rule translation FE.
The traffic monitoring FE monitors the real time traffic load information by receiving information
from the policy and rule translation FE with this reference point.

IDF-NS the reference point between the data forwarding FE and the network status reporting FE.
The network status reporting FE retrieves the traffic information (such as data processing
information) from the data forwarding FE with this reference point.
