Bandwidth management for resource reservation label switched path of a ring network

A network device comprising:

• a plurality of physical interfaces for receiving traffic from two or more network devices of a plurality of network devices in a ring network;
• and
• one or more processors configured to:
• receive, from an egress network device of the ring network, a resource reservation request message to establish a multipoint-to-point (MP2P) ring label switched path (LSP), wherein the resource reservation request message comprises a first sender template object specifying a first request for a first amount of bandwidth for a first segment of the MP2P ring LSP;
• modify the resource reservation request message to further comprise a second sender template object specifying a second request for a second amount of bandwidth for a second segment from the network device to the egress network device of the MP2P ring LSP, such that the second segment of the MP2P ring LSP has a different amount of bandwidth than the first segment of the MP2P ring LSP;
• and
• send the modified resource reservation request message to a downstream network device along the MP2P ring LSP.
