Okay. Let me expand with my theory.
I love to take the time to optimize my productions. For example I use many productions for iron plates. One is in the north, one west, one south of my factory. To have a working flow and do not use electricity for mines or assambling machines that cannot produce because there is a over production of this I connect them to a logical network to read the production rates and compare them with the consuming rates. As long as the difference is close under the golden ratio, the switches to mining areas are on. If the difference is over golden rat. my assambling machines are reduced in power.
Therefore it is important to get the overall process which is possible easily by connecting everything to one network.
But now I have the specific way that some productions of items of the same kind are not delivered by all iron plates I am creating but by the southern ones. So I want to switch off the way the iron could take for other productions. Therefore I need to get the overall signal of just the southern area. The global network is used by all plates so I need to create a new one or use a specific signal (e.g. a-z). But in that case you want to create everything with circuits and logical ways, the additional signals may be used already. So the only way is to create new networks apart of others. You can do it for sure but because of the power poles you need to grind wires the whole factory looks like a horror scenario.
And after 100 networks onto your factories and power poles just everywhere it's not that easy to plan or build machines the way you (or in this case I) like to.
So this brought me to this idea.
For my scenario I need following "instruments" (explanation later on):
-red/green wire for LAN
-other colored network wire for DSL
-A Server/Routing Point for interaction with LAN
-A Data Centre (DC) for transmitting and recieving special data of interest.
The first step would be to create a local area network (the way you are already doing this). For example you can count the amount of iron plates production or the amount of iron plates availible in a special area (chests, on transport belt, etc.). This data would be transmitted in the whole LAN with red and green wire. Both do the same but the changed color is quite good for visual and optical things or even when you need to handle two different LANs on the same places. That's all to say to red/green wires (i call LAN here) because everyone knows this way aroung.
Server/Routing Points: The server/routing points (R/SP) are the interfaces you need to use to connect the inforamtion to the DataCentre with "internet/DSL". The R/SP is connected to the LAN with normal red/green wire on one of the sides. The S/RP itself is handled like the combinators but transmit everything of its LAN-information to net DSL-network (what happenens to network is explaning at DataCentre) but is only able to recieve a few information from the data centre (which may be needed to get some information you need for combinator's decisions). For example lvl 1 R/SP is able to recieve 1 signal, lvl 2 recieves 2 and lvl 3 4 signals... or something like this.
DataCentre: The DataCentre is the main structure of this internet. The DataStructure can only be connected within blue DSL-wires to other DataCentres or to R/SPs. The main difference between DC and R/SP is that the R/SP is able to transmit everything in his LAN to DSL but the DC is only able to recieve and handle a few signals to the DSL-network. DataCentres are only availible to handle (1+lvl) items in their network (how many levels DCs can be upgrades is not relavant at this moment. So while the R/SP theoreticly could transmit everything to DC the DC will only ask for two specific data-values (on lvl1).
In our example you can select in the DC the network with internal ID 1 (Iron Plates) and this DataCentre will handle these dataValues. So every other DataCentre connected to this one is able to read the Network-1-Iron-Value when these DCs are also set up for ID-1-Iron-Values.
So if you decide to have two or even more DataCentres to transmit this signal over a large area you need to set up ID-1-Iron-Signal in every DataCentre which is transmitting this signal. The second Iron production you build on the other half of the factory can now set up in the second transmitting slot (level 1 DC has 2 slots) and gets the value for the new network ID (e.g. 319). So the DCs are now transmitting both iron plates signals (when set up in every DC which needs to transmit these signals) seperatly. If you need to use them for arethmetic or something else you can build a R/SP and let the R/SP recieve both signals and turn them into specific signals in its own LAN to take you calculations. These calculations can be made far far away from the factory on a place you do not need for anything else. After you have made a new signal you can transmit this signal to you R/SP and transport this via the DC (on blue DSL wires) when the DC reaches the level to handle that many different signals.
But there are some restrictions to that DCs. A DC is only able to connect a small amount of R/SP at the same time and just a few numbers of other DCs. First: Every DC who has R/SP(s) connected to it can only be connected to one more DC. Every DC which is not connected to any R/SP can communicate with 3 other DCs to transmit and recieve dataValues. To bring up Signal A from DC1 over DC 2, DC3 and DC4, all DCs need to be set up with this signal A. When any DC in the transmitting path is not transmitting signal A the dataValue of signal A is not transmited to the last DCs and stops where the continous path stops. A higher level DC is able to transmit more values. But the other DCs will only get the values they contain. For example:
we have 5 DCs in cross. DC "centre" is in the centre and the DCs "north", "south", "west" and "east" are at their positions. All of them are only connected to DC "centre". North is level 1 and transmit ID1-Iron-Plates. West is lvl 1 and transmit ID1-Iron Plates and ID1-Copper-Plates. South is lvl 2 and transmit ID1-Copper-Plates, ID4-coal and ID9-oil, east is lvl 2 and transmit ID3-Iron Plates, ID18-munition and ID9-oil. Centre is lvl 4 and transmit ID1-Iron Plates, ID4-coal, ID3-Iron-Plates and ID9-oil.
That means that north can see west's Iron-Plate's value because it's transmitted by west, centre and itself.
west only notice the ID1-Iron Plates but not south's Copper Plates because ID1-Copper Plates are not grind by the DC centre.
East and south are connected within ID9 oil. Centre is seeing ID4's coal value from east but not the number of munition.
the blue wire has max. length of 40 tiles and can only be connected to DCs or R/SPs with the limitation that a R/SP can only be 5 tiles away from DC. The blue wires cannot be extended by power poles and are not shown on the map. These blue wires' connections are only displayed when you click onto a DC. The reason is: They are laying underground.
These districtions make the DC useful for single signals but will not make them to overpowered because they are only transmitting a few little signals. But the best point is that you can transmit single signals over the whole map in an uncomplicated way without confusing yourself with tons of red and green wires all around. But when you need more signals you have to build more DCs and connect them wisely. But they are expensive to not overfill the world with them and use them only when needed.
Because DCs needs some security expansions it's better to build them with cement, steel, copper wires (for electricity in the building) and [servers] (of course a DC needs to have servers to work)
Servers created with [serverframes] and [Computers].
Serverframes are created with are Iron Plates, Copper Plates and plastic (to make the frames solid)
Computers are created with Processing Units, [Twisted-Pair-Wire], green circuit and plastic
R/SP are build with [Computer] and [Computerframes] and red circuits (doen't knwo the name for them now
)
Computerframes are build the same way [serverframes] are but for 1/4 of their costs because you only need one computer in there.
DSL-wire (e.g. blue) is created with [Twisted-Pair-Wire], red circuits and green circuits (so here are the network-cards integrated)
[Twisted-Pair-Wires] are created with copper wire, red-wire, green-wire and [Wire-coat] (for data-wires and coat)
[Wire-Coat] is created with plastic, iron plates and lubricant (Plastic for the coat, iron plates for protective Screen and grounding and lubricant for the overall processing of wires)
The items to be built with or the item's values and level-strength are just examples. Of course this needs to be balanced. But this way you could get some easy way to handle single signals but with a price of high costs and long producing times and steps in here.
I hope I have showed up what I mean with this. And with these restrictions and the example I do not find that this solution is useless or overpowered. It's a solution for single signals transprtet over large areas withing their costs, positive and negative characteristics
