NDI BANDWIDTH

[Myngus]

Hi all,

I'm running WO systems on a Cisco 1Gb unmanaged switch. No problems at all.

I'd like to introduce a NDI stream (not HX) at 3840 x 1080 @ 50. 

1 x NDI source, being received on 2 x Production PCs, and 2 x Display PCs.

Question 1: As I'm receiving it on 4 x PC's, does that mean I'm using 4 x the bandwidth?

Question 2: It would be nice to monitor the network traffic, to see how much bandwidth I'm using up, but as it's an unmanaged switch, I'm not sure how. Any ideas?

cheers guys.

I believe that the server computer is using 4x the bandwidth and each client only 1x

But you can confirm this by using HWinfo.

Run a copy on all computers, set the Production as client and all the other as servers.

You can monitor everything that matters including network bandwidth.

unicast mode:

NDI TX is transmitting a ~350Mbps stream to each receiver, so it needs approx 350x4 Mbps bandwidth in upload (AKA not possible in a 1Gbps network).
Each receiver (for instance each computer display and each production if you're gonna use preview) is using ~350Mbps bandwidth in download.

 

multicast mode (but you will need a managed and properly configured network switch):

NDI TX is transmitting a ~350Mbps stream to the whole network, so it needs approx 350 Mbps bandwidth in upload.
Each receiver (for instance each computer display and each production if you're gonna use preview) is using ~350Mbps bandwidth in download.
