Functional description
The Real-time Transport Protocol (RTP) Media Portal is an optional component of the network that performs many media-layer functions. The RTP Media Portal addresses media specific issues with advanced service delivery, Internet addressing efficiencies, and system security. It functions as a media Network Address and Port Translation (NAPT) point that shields private network components from external exposure through leaks in the media streams. The RTP Media Portal also enables elements in the private network to safely communicate with elements in the public network. The RTP Media Portal provides IP address/port pair mapping between internal and external network components, as well as media anchoring and media pivot abilities for terminals.
Figure 1, “Network Component Interoperability,” on page 4 is a graphical representation of the RTP Media Portal interworking among other components in the Multimedia Communications Portfolio.
