This guide is to provide insight into sources of packet loss, as well as where to get colored cables.

I have yet to see an indepth guide focused on either.

Packet loss is for the most part caused by reflections in our Tunnet system. This comes in the form of endpoints relaying and filters.

Two packets cannot exist on the same Tunnet node. Should two packets attempt to be on the same node, caused by a reflection of a packet going a->b with a packet passing through b->a, one packet is always deleted or bounced the wrong direction.


In the case of endpoints, this comes in the form that an endpoint will fail to emit its own packet if it has to reflect another packet.

This means in practice that the more times you bounce a packet off an endpoint the more packet loss you get if that endpoint is trying to emit.


Filters can also cause deletion of packets, This mechanic is well documented in other guides and will not be discussed in great detail here.

A point should be made that signals filtered at the level of *.*.*.a will cause the same packet loss as reflecting the signal off the endpoint. Therefore, it is always beneficial to filter at the *.*.*.a. This is because most systems are designed with mainframe packets in mind.


Antennas are the under appreciated redheaded stepchild of Tunnet equipment because you dont strictly need them for anything.

Even worse, antenna pairs can only operate if you do not place any other antennas in a radius equal to the distance between the antenna pair.

That being said, antenna are great not for wireless communications, but unidirectional merging. Two antennas placed next to eachother in place of one relay allow for a third antenna or fourth antenna to add information to the network and never take it away.

The reason I mention antenna is, like, filters, they create packet loss as a result of trying to merge two packets on the same line.

Antenna in a chain with distances constantly ascending with reflector filters can be used to unidirectionally merge packets from streams of any length. Though this is inefficient.

So be warned when using antenna, they do generate packet loss depending on the synchronicity of the incoming packets.



Endpoints that receive packets will sometimes send packets. Therefore, while not strictly packet loss, failing to send certain packets to certain endpoints will make those endpoints themselves not send packets.

I managed to play the majority of this game without ever finding any cable colors. This is due to the fact I went to the mainframe 0.2.0.0 after 0.0.0.0.

Cables can be acquired at 0.1.0.2 by talking to the school child. He will then send you on hide and seek runs to find him and get more.

Something that may be tempting in Tunnet is to try and run everything through a central filter. While this works from mainframe to endpoints with low flow, it doesn't really work to endpoints with saturated flow.

What I mean to say is, mainframes are not the only item that constantly puts out a packets. Some endpoints are fully capable of saturating their output line. If you then try to reintegrate this flow with the mainframe prior to filtering, only one of them would be able to send.

Furthermore, if you tried to integrate the flow when we have filtered half of the lines of a mainframe, such as having filtered of 0.1.0.a and 0.1.0.b, there will only be space for half of our endpoints output.

To get around this, you have to create new filters specifically for saturating end points, and send said those filtered signals with the filtered signals of other endpoints and main frames. This reduces packet loss and can even create situations where you create a new saturated but filtered line of combined signals if the phases are right.
