Doubts on how bridge works

Hello,
I have two MCM and one MCS. They are all connected to the same switch. If I assign a source to MCM 01 the probing of that source is done by this MCM. If I create a Mosaic output on the same MCM to see that source the SD point consumption on MCM 01 for an HD source should = 5 SD points. If I want to have that source still probed by MCM 01 but feeding a Mosaic output on MCM 02 (I will remove the tile on Mosaic MCM 01 output) what happens? The 5 SD points will be consumed by MCM 02 because of the channel Bridging or the probing on MCM 01 will still take 5 SD points? If that is the case I would consume 5 SD points on MCM 01 for probing and 5 SD points on MCM 02 for channel bridging.
Kind regards
Mauro

Hi Mauro thanks for reaching out.
You are correct, the points consumed by the monitoring engine are seperate from the bridge display mechanism.
So if you monitor a source on MCM 1 and display it on MCM 2 then it will consume 5 points from each servers.
Note that in case you are using a source that consumes less then 5 points for the monitoring, then the bridge will also consume the same number of points (like an SD source that consumes 2 points, the bridge will also consume 2 points.
If you’re monitoring a source that consumes more then 5 points, then the bridge will still consume 5 points, so the maximum points a bridge channel can consume is 5 points.
Let us know if you have any further questions.

Hi Nir.
So the benefit of the bridge display mechanism in the end is that I can save licenses but not computing resources.
Actually I would say that in addition to licenses I could save HW resources i.e. a NIC of the TAG that I use for the bridge display mechanism (I mean I will have the sources on TAG #1 through its dedicated NIC and I would not bother to set up a NIC of TAG #2 on the same source network of TAG#1 and the replicate the same sources.)
Am I correct?
Kind regards
Mauro

Hi Mauro.
Yes, you save licenses, and you can also save computing resources, depending on how you use the bridge.
Example:
You have a 1080P @30 Mbps source that is worth 20 capacity points. when you transfer it through the bridge then it will consume 5 points from the server generating the mosaic, where if you ingest it twice without the bridge (once to every MCM) then you will spend a total of 40 points, instead of 25 with the bridge.
Note that if you have a single bridge channel that needs to be displayed on multiple mosaics GENERATED BY THE SAME MCM, then it will only consume 5 points from that MCM, and not 5 per each time you display it.
The NIC used to transfer the bridge can be any NIC on the two MCMs, it doesn’t have to be the same NIC that recieves the source from the media network.
Note that there is a calculation that needs to be done to make sure the bridge network has enough bandwidth, please refer to this bridge article to understand the parameters that affect the bridhe channel bandwidth.

Thanks

Thanks Nir.
Have a nice day
