Interface Control Information
- Interface Control Information
-
Die ICI oder Interface Control Information bezeichnet die Schnittstellensteuerinformation zwischen den verschiedenen Schichten des OSI-Layer Modells.
Die Steuerinformationen dienen dazu, der darunter liegenden Schicht Steuerinformationen zu übermitteln, die die Behandlung der zugehörigen SDU durch die diensterbringende Schicht näher beschreibt. Sie werden in der dienstnutzenden Schicht erzeugt und in der diensterbringenden Schicht terminiert.
Es handelt sich also um eine rein vertikale Kommunikation, die nur Relevanz zwischen zwei Schichten hat.
