RTP - Real-Time Transport Protocol
NicheStack RTP/RTCP
Developed specifically for embedded devices, NicheStack RTP
adds streaming data services to NicheStack v4 and provides
end-to-end delivery services over UDP for data with real-time
characteristics, such as VoIP, interactive audio and video and
streaming multi-media. Those services include payload type
identification, sequence numbering, time stamping and delivery
monitoring. RTP data transport is augmented with RTCP. The
Real-time Transport Control Protocol monitors the quality of
service and conveys information about the participants of an
ongoing session.
NicheStack RTP/RTCP supports all of the required elements of
RFC3350, including:
- Multiple concurrent RTP UDP unicast and multicast sessions.
- Multiple send and receive streams per session
- Jitter buffer with configurable depth
- RTCP information and statistics for all session participants, including jitter delay, packets loss and timestamps.
Flexible Support for Real-Time Streaming Applications
Through its extensive API, nearly every parameter discussed in
the RFC is available to the application level, dramatically
increasing the likelihood of an "easy port" of a real-time
application to NicheStack RTP and freeing the developer to
work on the more important aspects of the applications such as
the RTP payload, the application profile, type code, transport
mapping and the audio and video encoding.
