Webcasting and available bandwidth

Postby kwillisjr » Tue May 17, 2016 7:38 am

We have had several webcast broadcasts from our stake center that have failed. So far as any of us can determine, all protocols are being followed and the equipment and network are functioning properly. I have wondered if there is an issue with what others in the neighborhood are doing during the times when we are trying to run a broadcast. I have heard that it is possible for the neighborhood to place such a demand on the system that we are not able to have the bandwidth we need (the building has a 50 Mbps connection). First, is it possible for the usage to be so high in the surrounding community that it causes a shortage in our building. If so, is there a way to monitor the available bandwidth coming from the ISP so that we can observe what effect community usage is having on us?

Yes.

Sort of. Sites like http://www.speedtest.net can do a spot test of your capacity by loading it up to failure. You can't really do that during the broadcast or if anyone else is using the network. (It can't compensate for any other use of your connection.) But even then, it's only a test at that moment, not a on-going test.

This is a situation where the broadcast stats are useful to figuring out where the problem is.

Not sure of the specifics of your failure, but surprised with 50Mbps you are having issues. What is your upload speed? The upload for the broadcast site for the Teradek VidiU using Standard Definition quality is 1.5 Mbps, the receiving download sites 1.0 Mbps. For HD you need more like 4Mbps upload and 2.1 Mbps down, but it’s recommended doing webcast in SD even if your camera supports HD. If using the Teradek make sure all the settings are set correctly: https://www.lds.org/help/support/contro ... u?lang=eng. Not sure if you did this, but it’s a good idea to turn off the Wi-Fi temporarily in the building since a full congregation connecting to Wi-Fi can cause some issues https://www.lds.org/help/support/disabl ... s?lang=eng. Make sure your webcast equipment is not on wireless when you shut it off, but I would not use wireless for your webcast anyway, use both hardwire network cable for both the broadcast and receiving equipment. As far as testing bandwidth, the following page needs to be updated since the Church no longer use the speed test site that its shows, but the principles are the same by just using speedtest.net as suggested https://www.lds.org/help/support/intern ... t?lang=eng .

I'm also wondering if you are using cable or fiber for the connection. Usually cable is a shared resource where fiber is direct connect to the switch. Also, Cable is set up that the upload speed is lower than the download speed. It isn't like FIOS (Verizon Fiber) that does speed match, meaning 50 down and 50 up. So FIOS runs more like a LAN than the cable companies do.

Are you disabling Wifi in the building so that the bandwidth is focused on the webcast? We have to do this at our buildings because with 200+ devices trying to connect to the building WiFi it was placing too much of a strain on the system and using up all the bandwidth. We run hard cat-5 cables from our wall jacks (in our newer buildings that were built with cat-5 infrastructure) to the devices/laptops streaming the webcasting. Works well, since we started doing this. Even in the buildings where we are limited to 1.5 or 3M. (out in the boonies where no faster speed is available)

As I can understand, webcast is a server based system and the server is (are?) placed in SLC.
If, and only if, this is true data has to go and went from you and HQ.
No idea where you live, but for us (Italy) this would mean: Cross the Ocean. :D

Server-based, yes. But the new system is "cloud" based, possibly with Microsoft Azure. The server's location is based on the region selected when scheduling the event. In your case, you'd have a choice between "West-Europe" and "North Europe".
