[MCH-Partytent] VLAN for Bar-audio & Party-area requirements

Hello Team NOC,

On request of Netsmurf I’m working on a solution for shared audio between the various bars and the Party-area on MCH2022.
I’m planning to use Dante audio via IP (https://www.audinate.com/meet-dante/what-is-dante)  for this.

The main reason is that “the network is everywhere” on MCH, so using the network for this will prevent a lot of extra (audio) cable length that has to be installed and removed again.
Since Dante (Like most AV network implementations) is not really secured, one requirement is to have an isolated/dedicated subnet.
This subnet does not need internet access or any network services (a remark regarding DHCP for this network is made below).
It should be a single VLAN since Dante is not capable of traversing routers without adding an expensive “domain manager” (if really needed, we might see if we can get a sponsor deal or trail version of this product for MCH).
A “nice to have” function would be PoE on the Dante network patches, if this is not possible I will add small PoE capable switches and/or PoE injectors where needed.

For now we see a demand for this subnet on the following locations on the terrain (this may be subject to change):

  *   Party Area (see party-area specifics below)
  *   Main bar 1:  2 PoE connections or a single connection that we can use to connect a PoE enables switch.
  *   Main bar 2: 1 PoE connection.
  *   Beach bar: 1 PoE connection.
  *   Batch bar: 1 PoE connection.
  *   Other bar locations?: 1 PoE connection.
Remark: if no PoE available on one or more locations, let us know, we will then us a PoE injector

Next to this we have some request for the network in the party-area.
Since we will use several different network-related services within the party area, we will deploy our own network for the partyarea.
Most of the service we will run here will not need any connection with the internet or other external network.
However, for some applications it is convenient to have internet access and we need access to the Dante VLAN as requested/described above.
So if possible., we would like to connect to the MCH network with a trunk that allows access to the internet and the Dante network. If a trunk is not possible or inconvenient, two separate connections will probably also work.
The deployed network in the party-area will consist of Cisco Catalyst switches and a PF-Sense firewall.
It would have my preference to connect to the MCH network by fiber, but copper-ethernet is  also possible.
We can provide the (fiber)length to connect to a nearby connection point (up to 500m, if more length is needed: let’s discuss).

For the Dante network DHCP is not necessarily (Dante works fine with the Self-assigned address-spaces), but obviously devices initiate quicker when there is a DHCP service available.
The infrastructure we are providing for the party-area can provide the DHCP service for the whole Dante VLAN. But if you prefer to deliver DHCP service from the MCH network, of use Self-Assigned IP’s that fine too, just let me know.

I can imagine this email raises some questions, if so: contact me on steven at phoxit.nl<mailto:steven at phoxit.nl> or +31610948973 (Signal also active on this number)

Best Regards,
Steven Geerts
