    Managing MX Series Routers Acting as a PCEF Using the SRC Software Overview

    The SRC software acting as a PCRF uses the Gx router driver to establish a southbound Gx interface between the SRC software and the MX Series router (that is, Services Control Gateway) acting as a PCEF. The SRC software provisions static PCC rules, dynamic PCC rules, or dynamic ePCC rules to the Services Control Gateway over the Gx interface using the Diameter attribute-value pairs (AVPs). The SRC software can also send a Diameter message over the Gx interface to the Services Control Gateway to activate the rules predefined on the Services Control Gateway. The Services Control Gateway enforces policy decisions specified by the rules and also provides usage monitoring information and subscriber information to the SRC software. The SRC software uses the Diameter protocol for communication between the SRC software and the Services Control Gateway.

    Figure 1 represents the interface between the SRC software and the Services Control Gateway.
