Summary TE using virtual topology quick reconfiguration in multi-layer. Topology info (FA-LSP) & traffic info of lower-layer LSP No centralized coordination Traffic measurement is advertised with FA-LSP. New Sub-TLVs for Opaque-LSA in OSPF/ISIS GMPLS extensions. Next step Revisions Traffic measurement mechanism Virtual topology algorithm Hierarchical FA-LSP setup/teardown procedure in a graceful way Start discussion on multi-layer path network control using GMPLS. Comments are appreciated!!!
