SDP Local Identifier
2011
Dynamic Policy Controllers like resource and admission control systems
need to be able to locate media receivers in each segment of the
network to determine the path of the media flows prior to allowing or
rejecting the session setup. This is fine as long as this is handled
within an operator's network but limited when extending this to
home network. Current definitions of SDP are not clear about conveying
a local identifier (e.g., a private IP address) of the client that is
destined to receive media streams after successful SDP negotiation. In
this draft we outline the need for carrying such information over SDP
and discuss a set of possible solutions in a scenario with a home
network and a operator network domain.
