H04L 12/709 - Definition

Definition statement

This subclass covers:

The calculation of several paths between two endpoints and the simultaneous use of said paths. This entry also concerns the selection, setup, maintenance and tear down of the routes. The routes can be used for several purposes: load balancing, security, fail safety, higher aggregate bandwidth... The creation and use of a trunk group is also covered by this entry.

Relationship between large subject matter areas

The purpose or application of the multiple paths should be classified in the corresponding entries elsewhere in the IPC, e.g. documents dealing with the criteria used for load balancing among a plurality of paths should only be classified in H04L 12/803 and not in this subgroup.
