Abstract:
The wide deployment of Voice over IP (VoIP), real-time text, and Video over
IP services has introduced new challenges in managing and maintaining real-time voice/text/video quality, reliability, and overall
performance. In particular, media delivery is an area that needs attention. One method of meeting these
challenges is monitoring the media delivery performance by looping media back to the transmitter. This is
typically referred to as "active monitoring" of services. Media loopback is especially popular in ensuring the
quality of transport to the edge of a given VoIP, real-time text, or Video over IP
service. Today, in networks that deliver real-time media, short of running 'ping' and
'traceroute' to the edge, administrators are left without the necessary tools to actively
monitor, manage, and diagnose quality issues with their service. The extension
defined herein adds new Session Description Protocol (SDP) media types and
attributes that enable establishment of media sessions where the media is looped back to
the transmitter. Such media sessions will serve as monitoring and troubleshooting tools
by providing the means for measurement of more advanced VoIP, real-time text,
and Video over IP performance metrics.
