As there are 7 layers... 7 days in a week, we could start with Layer 1- Physical, and have a talk about the most important thing- cabling, and what works and what doesn't and move on up from there.any takers?
...To be totally transparent- it would be totally inappropriate to start this thread myself - it would be wrong for a manufacturer to "take ownership" of this... ...
Or better yet, the manufacturer could take full ownership of this and issue a white paper on audio networking on their website. Kieran I very much appreciate your posting both here and on the Blue Room forum this extremely valuable illumination of some of the darker elements of network application as it relates to Dante implementation. Combined with the Yamaha networking 'lite' tutorials still in progress it makes understanding this brave new world much more accessible. I would very much like to see Audinate step up to the plate with this sort of information support as a base part of their product offering. Audinate may feel that their customers are the audio device manufacturers that incorporate this technology into their products but I suspect that the key to seeing Dante successfully pull ahead of the pack in the audio networking market will be promulgating a widespread understanding of the merits of your product over the competition. This sort of out reach can be that competitive edge.
Kieran,I'm the OP of this thread. Back to my original question...I'm running a GLD112 with Dante and an new (1Gb) airport extreme. Do you think it is reasonable to connect my MacbookPro to the AirPort Extreme by cat cable, and then connect the Dante card (@32x32) and the GLD Ethernet control to the AirPort Extreme Gb ports, or should I run Dante direct to my laptop by cable and connect the laptop wirelessly to the AirPort Extreme for GLD control functions.There are a few other devices on the network like a DSP and Sennheiser WSM but there would be basically no traffic to these devices during a show.Even though the airport express doesn't support QoS, it seems like there will be plenty of bandwidth in the airport express for unicast 32x32 to just wire things together without worrying about VLANs
Indeed- back to the point...This is a really good question... and a good opportunity to go through how I would consider this in a step by step way...The big unknown here as far as I see it is the airport extreme, and the wired performance therein... i'm trying to find a datasheet to confirm some performance questions I have...Assuming that the switch between the wired ports is a non-blocking, and completely "dumb" unmanaged switch then the setup you describe "could" be OK... I will keep looking for definitive info on this, and/or devise a test to try this out.The three ports on the front of the M-Dante card are ports of a Gigabit switch...The control port has filtering enabled to prevent multicast audio from swamping the control port (it would be advisable to check release notes and firmware update to verify this from A&H - I do know that they have written a very good advisory on some of the extensive testing that they undertake)It is not clear to me from the quoted description at least whether you are running the M-Dante card in redundant or switched mode. I believe that in either case the control port will filter multicast traffic in the latest firmware version... again - please check with A&H release notes for confirmation - looking at their documentation firmware above 3.5.x should work fine.SO I would suggest that you connect the control ethernet of the GLD to the control port of the M-Dante card - put the M-Dante card in switched mode, attach the airport extreme to either the "primary" or "secondary" port of the M-Dante card, with your virtual soundcard machine plugged into the other network port of the M-Dante card.I hope that this covers the main points- please let me know how you get on
To the OPIt seems to me you are overthinking this. I think most current routers ( with a WAP ) that have more than one network connector on the subscriber (as opposed to the internet) side have an integrated non-managed switch inside.
In my last post I mentioned unicast. I don't see any need for multicast with a single source and receiver of the multitrack audio stream. Maybe I missed something.
