Abstract
Systems and methods include determining a Multi-Point to Point (MP2P) tree from a plurality of source nodes to a destination node in a Segment Routing network, wherein the plurality of source nodes are sending traffic with guaranteed bandwidth requirements to the destination node, and wherein the MP2P tree is determined based on the guaranteed bandwidth; assigning a globally unique Segment Identifier (SID) for the MP2P tree; and causing programming of forwarding entries in the plurality of source nodes, any intermediate nodes, and the destination node, based on the MP2P tree. The steps can further include receiving measurements from nodes on the MP2P tree of bandwidth utilized against the globally unique SID; and updating the MP2P tree if required based on the measurements. Each of the plurality of source nodes utilize the globally unique SID to send traffic with guaranteed bandwidth requirements to the destination node.
