Topology update or discovery

Introduced: January 2022

Full Title

Full titles differ between systems:

IPC:

Routing or path finding of packets in data switching networks > Topology update or discovery

CPC:

Routing or path finding of packets in data switching networks (routing or path finding in wireless networks H04W40/00) > Topology update or discovery

Of 12 combined children, 6 exist in both systems.

6 codes are CPC-only extensions.

IPC defines codes here since 2022.
