z
RemoteConnectionDescriptor (RC)
The RemoteConnectionDescriptor includes the same fields as in the
LocalConnectionDescriptor, such as IP address, UDP port and packetization
parameters. For the
CreateConnection
command, this parameter may have a null
value when the information for the remote end is not known yet. This occurs because
the entity that builds a connection starts by sending a
CreateConnection
to one of
the two gateways involved in it. For the first
CreateConnection
issued, there is no
information available about the other side of the connection. This information may be
provided in SDP packets later through a
ModifyConnection
call.
z
LocalConnectionDescriptor (LC)
The LocalConnectionDescriptor is a session description that contains information
about IP address and port number suitable for the local connection, as defined in SDP.
