Another good resource is the
FMS Whitepaper, which explains how the networking is set up.
The gist of it:
- Each team is on its own VLAN, so one team's robot/DS can't communicate with anything except FMS.
- Additionally, FMS only allows the ports specified in the manual though (so if you really care to mimic it, you can setup your own firewall and only whitelist the given ports). Otherwise, just ensure to disable the firewall on your DS entirely, so it doesn't block things it shouldn't, like mentioned above.
- The
field AP robot radio enforces a 7 megabit/second bandwidth cap. You can enable this while the radio is programmed for home use, as well
Aside from that, there's no substantial difference between the field network and a home network. After all, it's all "just a network", even on the field.
