===Batman fliegt durchs Weimarnetz...===
...oder besser flog.
Nach ungefaehr 12 Stunden Laufzeit wurde BATMAN2 auf allen Routern im Weimarnetz wieder deaktiviert.
Warum dieses kurze Debüt? Nachdem ein Blick auf einige Router zweifelsfrei gezeigt hat, das die CPUs ganz schoen schnaufen, haben wir uns dazu entschlossen die Notbremse zu ziehen und auf die naechste Version des Routing-Dienstes zu warten. Die erhofften Vorteile - geringer Speicherbedarf und geringe CPU-Belastung - stellten sich teilweise als nicht richtig heraus.
Aber: BATMAN funktionierte.
So bleibt nach allen Strapazen jedoch die Gewissheit nur ein Minimum an Speicherplatz verschwendet zu haben. Bastian Bittorf / Fries43 - weimarnetz
