H04L 12/427

with decentralised control

Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Data switching networks > characterised by path configuration, e.g. LAN [Local Area Networks] or WAN [Wide Area Networks] > Loop networks > with decentralised control

CPC:

Data switching networks (interconnection of, or transfer of information or other signals between, memories, input/output devices or central processing units G06F13/00) > characterised by path configuration, e.g. LAN [Local Area Networks] or WAN [Wide Area Networks] (wireless communication networks H04W ) > Loop networks > with decentralised control

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1995.
