152 Communication Infrastructure (page 152)

Communication Infrastructure

The infrastructure for communication over distance consist of several layer. One layer for the information. One layer converting (or enveloping) the information to some kind of standard envelope or package. One layer for the adresses where the message should be send and where to receive the answer. One layer for transportation of the message. This is also the case of instant two ways or several ways of communication. 2016-07-31

The media for transportation can be both traditional physical medias like wagons, cars, ships, horseback or airplanes but also visual or audi accoustic like signalflags, smokesignals, melodies, morsecode (both sound and light). The sound signals can also be transported through radio waves or electric wires.

The most used media to day are wires and radio wave where the information is converted to digital packages. The most used packaging format is TCP/IP and the most used media is the internet. The transportation media for TCP/IP communication can even be pidgeons which was demonstrated in Norway at an April Fools Day*. It is the RFC 1149 IP Datagrams on Avian Carriers. 2016-07-31

* The RFC itself was requested 1st 1990-04-01 but was retified in Bergen, Norway 2001-04-28
   when one of the leading Linux developers Alan Cox visited the Bergen Linux User Group (BLUG). So the April Fools day was for the RFC
