Received changes through RFC Editor sync (created alias RFC 8149, changed title to 'RSVP Extensions for Reoptimization of Loosely Routed Point-to-Multipoint Traffic Engineering Label Switched Paths (LSPs)', changed abstract to 'The reoptimization of a Point-to-Multipoint (P2MP) Traffic Engineering (TE) Label Switched Path (LSP) may be triggered based on the need to reoptimize an individual source-to-leaf (S2L) sub-LSP or a set of S2L sub-LSPs, both using the Sub-Group-based reoptimization method, or the entire P2MP-TE LSP tree using the Make-Before-Break (MBB) method.  This document discusses the application of the existing mechanisms for path reoptimization of loosely routed Point-to-Point (P2P) TE LSPs to the P2MP-TE LSPs, identifies issues in doing so, and defines procedures to address them.  When reoptimizing a large number of S2L sub-LSPs in a tree using the Sub-Group-based reoptimization method, the S2L sub-LSP descriptor list may need to be semantically fragmented.  This document defines the notion of a fragment identifier to help recipient nodes unambiguously reconstruct the fragmented S2L sub-LSP descriptor list.', changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2017-04-19, changed IESG state to RFC Published)
