Hi Dmtry,

 

This is text for 4.4:

 

4.4.Relationship to interface management and connection managers

 

Current devices such as mobile handsets make use of proprietary
mechanisms and custom applications to manage connectivity with multiple
interfaces and multiple PVDs. These mechanisms or applications are
commonly known as connection managers [RFC 6419]. 

 

Connection managers sometimes rely on policy servers to allow the
PVD-aware node making the PVD selection. They can also make use of
routing guidance from the network (e.g. 3GPP ANDSF [REF ANDSF]).
Although connection managers solve some connectivity problems, they
seldom address the PVD selection in a comprehensive manner. Moreover,
even with proprietary solutions, it is very challenging to present a
coherent behaviour to the end user of the device, as different platforms
present different behaviours even when connected to the same network,
with the same type of interface, and for the same purpose.
