Configuring MPX Nodes for redundant streams

Updated by Jake Alderman

SCOPE

Version 1.3.35 of the Omnia MPX Node adds redundant streaming capability. This document assumes the IP addresses have already been assigned to both network interfaces on each MPX Node. For assistance setting the IP address of the MPX Node please see the Quick Start Guide.

The design shown here is one method to build system redundant streams. Designs for more complex applications can be extrapolated from this document.

DESCRIPTION

If multiple IP networks are available, it is possible to send redundant streams and have the decoder reconcile MPX signals on a packet-by-packet basis. For this example, there will be 2 internet service providers at both the Studio and Transmitter sites.

Requirements

  1. Version 1.3.35 or newer software is required. If the MPX Node needs to be updated please click here.
  2. You must know both of the public static IP addresses
  3. Port forward the same port through both firewalls at the transmitter site

Configuring the Decoder MPX Node

  1. Using your web browser, navigate to the main web page of your decoder MPX Node.
TIP - The IP Address of your MPX Node can be obtained by repeatedly tapping the upper user button on the front panel until the IP Address is displayed.
  1. Log in with your user name and password.
  2. Open the µMPX Setup Menu
  3. Turn off the µMPX Decoder
  4. Find the stream receiver section
  5. Set the Main port number to the one that is forwarded through both routers
  6. Click Save
  7. Turn on the µMPX Decoder
  8. Make sure the main port shows as the active port

Configuration of the Decoder is now complete. Move on to configuration of the encoder MPX Node for system testing.

Configuring the Encoder MPX Node

  1. Using your web browser, navigate to the main web page of your encoder MPX Node.
TIP - The IP Address of your MPX Node can be obtained by repeatedly tapping the upper user button on the front panel until the IP Address is displayed.
  1. Log in with your user name and password.
  2. Open the µMPX Setup Menu
  3. Scroll down to the Streams section
  4. In the first stream type the Public IP Address that should act as the primary receiver
  5. Type in the port number that is forwarded through the firewall
  6. Using the Network drop-down select the NET 1 Interface
  7. Click save
  8. Turn the stream on
  9. In the second stream type the Public IP Address that should act as the primary receiver
  10. Type in the same port number used in Step 6 that is forwarded through the firewall
  11. Using the Network drop-down select the NET 2 Interface
  12. Click save
  13. Turn the stream on

When finished, both NET 1 and NET 2 will be sending to the same IP and port address, but over separate networks.

System Testing

In the following testing, you are basically toggling between encoder streams to prove that, so long as one stream is being sent, a signal continues to be received at the Decoder.

In order to conduct system testing, you'll need access to web interfaces of both MPX Encode and Decode Nodes. We recommend switching to an alternate source of audio while testing the system to avoid disruptions to air
  1. Using your web browser, navigate to the main web page of your decoder MPX Node.
  2. Log in with your user name and password.
  3. Open another tab or browser window
  4. Navigate to the main web page of your encoder MPX Node.
  5. Log in with your user name and password.
  6. Open the µMPX Setup Menu
  7. Scroll down to the Streams section
  8. Verify both streams are in the on position
  9. Turn off the first stream
  10. Open the tab or window with the decoder
  11. Verify it still receives a stream
  12. Open the tab or window with the encoder
  13. Turn on the first stream
  14. Wait 5 seconds
  15. Turn off the second stream
  16. Open the tab or window with the decoder
  17. Verify the MPX Node still receives a stream

With testing complete, the system is now ready to go on air.
