Már a CCNA vizsgához is érdemes RFC-ket olvasni, pl. RIP. Az itt található RFC azonban kicsit másról szól

A címe: RFC 1925 – The Twelve Networking Truths, idézem hát a 12 igazságot a hálózatokkal kapcsolatban…

(1) It Has To Work.

(2) No matter how hard you push and no matter what the priority, you can’t increase the speed of light.

(2a) (corollary). No matter how hard you try, you can’t make a baby in much less than 9 months. Trying to speed this up *might* make it slower, but it won’t make it happen any quicker.

(3) With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead.

(4) Some things in life can never be fully appreciated nor understood unless experienced firsthand. Some things in networking can never be fully understood by someone who neither builds commercial networking equipment nor runs an operational network.

(5) It is always possible to aglutenate multiple separate problems into a single complex interdependent solution. In most cases this is a bad idea.

(6) It is easier to move a problem around (for example, by moving the problem to a different part of the overall network architecture) than it is to solve it.

(6a) (corollary). It is always possible to add another level of indirection.

(7) It is always something

(7a) (corollary). Good, Fast, Cheap: Pick any two (you can’t have all three).

(8) It is more complicated than you think.

(9) For all resources, whatever it is, you need more.

(9a) (corollary) Every networking problem always takes longer to solve than it seems like it should.

(10) One size never fits all.

(11) Every old idea will be proposed again with a different name and a different presentation, regardless of whether it works.

(11a) (corollary). See rule 6a.

(12) In protocol design, perfection has been reached not when there is nothing left to add, but when there is nothing left to take away.

Az RFC célja:

1. Introduction

   Military requirements place a high premium on ultra-robust systems
   capable of supporting communication in extremely hostile
   environments.  A major contributing factor in the survivability of
   systems is a high degree of redundancy.  CSCR believes that the
   system designs offered below exhibit extraordinary redundancy
   features which should be of great interest to DARPA and the
   Department of Defense.

Természetesen erre egy megoldás:

Jam-Resistant Land Mobile Communications

   This system uses a highly redundant optical communication technique
   to achieve ultra-low, ultra-robust transmission.  The basic unit is
   the M1A1 tank.  Each tank is labelled with the number 0 or 1 painted
   four feet high on the tank turret in yellow, day-glo luminescent
   paint.  Several detection methods are under consideration:

     (a)  A tree or sand-dune mounted forward observer (FO) radios
          of tanks moving in a serial column.  The mainframe decodes
          the binary values and voice-synthesizes the alphameric
          ASCII-encoded messages which is then radioed back to the
          FO.  The FO then dispatches a runner to his unit HQ with
          the message.  The system design includes two redundant,
          emergency back-up forward observers in different trees
          with a third in reserve in a foxhole.

          to a reach echelon main frame computer the binary values

Természetesen víz alatti kommunikáció is megoldható:

3. Low Speed Undersea Communication

   Using the 16" guns of the Battleship Missouri, a pulse-code modulated
   message will be transmitted via the Pacific Ocean to the Ames
   Research Center in California.  Using a combination of fixed and
   towed acoustic hydrophone arrays, the PCM signal will be detected,
   recorded, enhanced and analyzed both at fixed installations and
   aboard undersea vessels which have been suitably equipped.  An
   alternative acoustic source is to use M1A1 main battle tanks firing
   150 mm H.E. ordnance.  It is proposed to conduct tests of this method

   in the Persian Gulf during the summer of 1991.
