UDP-based Data Transfer Protocol
UDT support in Nimble Streamer
What is UDT
UDP-based Data Transfer Protocol (UDT)
is a high-performance data transfer protocol designed for transferring large volumetric datasets over high-speed wide area networks.
Key feaures include
- Speed. UDT is designed for extremely high speed networks and it has been used to support global data transfer of terabyte sized data sets.
- Bandwidth-friendly. Concurrent UDT flows can share the available bandwidth fairly, while UDT also leaves enough bandwidth for TCP.
UDT in Nimble Streamer
Nimble Streamer has full support for UDT protocol.
-
Both
Push
and
Listen
delivery modes are supported
-
Both
Listen
and
Pull
receive modes
can be used to get streams for further processing.
-
Rendezvous
mode can be used for both receiving and sending data.
-
Multiple streams can be sent via single UDT channel
-
Mux rate
can be set correctly
- Nimble Streamer has 100% PCR accuracy, 0ns PCR drift and PCR interval <20 ms according to StreamGuru.
This is typically used for precise testing of channel throughput.

UDT in complex scenarios
Nimble Streamer covers wide variety of live streaming scenarios so UDT can be used as an element in complex delivery scenarios.
-
Live Transcoder
allows processing incoming streams to change the content according to your business logic.
This includes decoding, applying various filters and encoding. All setup is performed via drag-n-drop web UI.
-
Process incoming streams via
RTMP
,

,
SRT
,
HLS
and UDT.
-
Produce RTMP, RTSP, MPEG-TS, SRT, HLS, MPEG-DASH, Icecast and UDT
outgoing streams.
-
Use
DVR feature set
to record incoming live streams and provide further playback via MPEG-DASH and HLS.
-
Build networks
of servers with Nimble Streamer to deliver the content in the most optimal way
Easy installation and upgrade
Nimble Streamer can be
installed
