"The CONEX congestion exposure mechanism is intended as a general technology that could be applied as a key element of congestion management solutions in a variety of use cases. The IETF CONEX WG will however work on a specific use case, where the end hosts and the network that contains the destination end host are CONEX-enabled but other networks need not be .. it can be said that traffic management in 3GPP EPS and other mobile communication architectures in very important. Previously more static approach based on admission control and static QoS have been applied, but recently, there has been a perceived need for more dynamic mechanisms such as DPI. Adding CONEX support might thus require revisiting the PCC architecture, depending on the scope and impact of a CONEX-based traffic management approach".
