There are applications that require bi-directional, co-routed and
guaranteed communication from a root node to several leaf nodes in a
hub and spoke fashion. To meet such application requirements in a
Multi-protocol Label Switching (MPLS) network this draft defines a
Hub and Spoke Multipoint Traffic Engineered Label Switched Path (HSMP
TE LSP) with resource reservations for guaranteed communication.
This draft also defines a protocol to setup such LSPs by re-using and
extending P2MP RSVP-TE.
