Abstract
Router advertisements containing name information from superordinate subnetworks are received by routers associated with subordinate subnetworks. The router advertisements are supplemented with a topological and/or hierarchical name component associated with the respective router and are distributed inside the respective subordinate subnetwork. Communication terminals independently generate their device name from topological and/or hierarchical name components and a unique name component inside their respective subnetwork.

A method of providing a naming service inside an industrial communication system comprising subordinate subnetworks, superordinate subnetworks, communication terminals, and routers, the method comprising:
- distributing IPv6 prefixes in the respectively subordinate subnetworks via routers with messages containing router advertisements, the router advertisements comprising a topological and/or hierarchical name component of the respective router, and the topological and/or hierarchical name component being associated with a spatial or hierarchical arrangement of the respective router,
- receiving router advertisements containing name information from superordinate subnetworks by routers associated with the subordinate subnetworks;
- supplementing the router advertisements with a topological and/or hierarchical name component associated with the respective router;
- distributing the supplemented router advertisements inside the respective subordinate subnetwork;
- and
- independently generating, by communication terminals, their device name from topological and/or hierarchical name components and a unique name component inside their respective subnetwork.
A router in an industrial communication system,
- wherein the router is configured such that IPv6 prefixes are distributed in respectively subordinate subnetworks using messages containing router advertisements,
- wherein the router advertisements comprise a topological and/or hierarchical name component of the respective router, and wherein the topological and/or hierarchical name component are associated with a spatial or hierarchical arrangement of the router, and
- wherein the router is configured such that router advertisements containing name information from superordinate subnetworks are received and are supplemented with a topological and/or hierarchical name component associated with the router and are distributed inside the respective subordinate subnetwork.
