+Es sind die 1960er Jahre, du arbeitest mit einem Kommilitonen an einem ersten Prototypen für miteinander vernetzte Computer.
+Der Algorithmus ist noch recht simpel.
+Zu simpel: denn jeder Rechner schickt von einer Verbindung in der einen Sekunde empfangene Nachrichten in der nächsten Sekunde einfach blind an alle anderen Verbindungen weiter.
+Wenn eine Nachricht aber gleichzeitig aus mehr als einer Verbindung eingeht,
+ crasht der Rechner und ist erst in der nächsten Sekunde wieder einsatzfähig --
+ ohne das soeben Empfangene weiterzusenden.
+\\
+Du versuchst natürlich, deinem Kommilitonen das als Nachricht auf den einzigen Rechner mit aktivierten Logs zu schicken.
+Aber den zu erreichen gestaltet sich erstaunlich schwierig,
+ denn du hast nur ein Kabel, und es reicht nur zu drei anderen Rechnern...
+Mit welcher Verbindung kommt die Nachricht sicher ans Ziel -- ohne dieses zu crashen?
