Abstract:
The wide deployment of Voice over IP (VoIP), 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 SDP media types and
attributes, which 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.
