How to transfer items between two networks?

[gphg]

An exporter (from network 1) and connected to a grabber (from network 2). But placing these next to each other basically connecting these two.

I asked the same thing on Discord server and BOOMER_1 replied with this:

Via cargo, importer and exporters or use storages as a bridge between the two

Cargo is reliable, but it got nerfed on some server due its performance issues. I just can't get the rest of his sentence. Are there intended way by developers?

My idea is using machines as bridge:

• One network (Network 1) pushing materials needed into the machine, in this case: the material is cobblestone and the machine is dust extractor.
• Another network (Network 2) grabbing result items by the machine in question.

That is my idea, but that does not even mentioned importer and exporter.

(BM)S(MB)
B = bridge,
M = monitor
S = quantum storage
the left BM belongs to Network 1
the right MB belongs to Network 2
quantum storage is not a part of network, it is just a storage

then you can open the grid and find the item in two networks at the same time
