It's a method of connecting an unlimited number of ME drives, annihilation planes, etc. to your ME network while only using a single channel on the main network by having a chain ad-hoc of subnetworks, each with a Storage Bus to connect it to the next subnet, an Interface to connect it to the previous subnet, and six additional channel-using devices that will be accessible to your main network.
People tend to go way overkill on their Controllers anyway, so it's rare that you'll actually have any reason to nest subnets like that.
Is this even possible? Are there charts showing how to do this? I'll look it as I hate having to build multiple bridges when I have little space to put them.
Toward the end of the video I linked earlier, Algorithm uses a long line of dense cable to power some P2P tunnels carrying channels for some devices away from the Controller. Just do the same thing, except replace most of the dense cable with a linked pair of quantum rings.
Also note that, to get the most out of your P2P tunnels, you'll want to make sure that they're all carrying as many channels as possible. At your home base, you'll need 32 (or however many you need) P2P tunnels either slapped right on the face of your Controller, or with its active face connected to the controller via an unbranching line of dense cable so you can see exactly how many channels you're using. The back sides of these tunnels must also be connected to a Controller, either your main one or a separate one if you prefer using a subnet. Then, place a line of dense cable connecting this controller to a quantum ring, and another coming out from the linked quantum ring at your secondary base. In order to use the quantum bridge most efficiently, you'll want to make sure that each P2P tunnel you connect to it is using the maximum number of channels- so each P2P tunnel at your home base should be linked to exactly one P2P tunnel in the remote base, and each remote P2P tunnel should have at least one dense cable coming out of it.
