Background Q.3303.3 proposes to use DIAMETER on Rw Interface. The Rw interface exists between Policy Decision Physical Entity (PD-PE) and the Policy Enforcement Physical Entity (PE-PE) where PD-PE acts as the diameter server and the PE-PE acts as the diameter client. Two modes of operation are defined on this interface PULL : PE-PE (Diameter Client) establishes session with PD-PE (Diameter Server). State Machine for this mode is defined in Diameter Base RFC(3588). PUSH : PD-PE (Diameter Server) establishes session with PE-PE (Diameter Client). State Machine for this mode is not defined in Diameter Base RFC(3588). |
