DIFF Subgroup
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.
