[ANSS-netops] reftek suddently stops streaming

[Kyle Persefield]

All,

FYI - All RT-130 firmware should be upgraded to 3.2.2 (Feb 26, 2010) 
or higher (3.3.1 July 22, 2011).  Preferably higher.

This stream of E-mails on this subject should be sent to Reftek at 
support at reftek.com to make sure they are aware of issues with their products

I believe some of the issues with the RT-130 data streams were 
addressed with the 3.2.2 version.  See below from the release notes.

10. Addition of an Adaptive Telemetry Re-transmit Algorithm
The RTP re-transmit interval has been modified to adjust the 
re-transmit interval based on the round trip time of the previously 
transmitted packets. The maximum RTP re-transmit interval is 10 seconds.
(Added in Version 3.1.0)

11. Addition of an Software Watchdog
A software watchdog has been implemented to monitor code execution.
(Added in Version 3.1.0)

12. Addition to the Behavior when Telemetry Connection is Lost
When the telemetry connection is lost, the DAS sends out Server 
Discoveries. After 5 minutes of sending Server Discoveries, the DAS 
will stop sending Server Discoveries for 2 minutes. This process is 
repeated until the connection is re-established In addition the DAS 
will display the message "RTP SLEEPING on the LCD during the 2 
minutes that Server Discoveries are suspended.
(Added in Version 3.2.0)

13. Addition to Cycle Ethernet Power Output
The Ethernet power output line (pin M - Net Connector) will now be 
powered off for 10 seconds if the RTP connection is down for 
approximately 80 minutes. This can be used to power cycle any radios 
that are powered by the 130. The 10 seconds power off will occur 
every 80 minutes until the RTP connection is re-established.
(Added in Version 3.2.0)

I cannot address how any individual router model or switch handles UDP.
