Presentation Transcript

  1. Framework for PCE-Based Inter-Layer MPLS and GMPLS Traffic Engineering draft-ietf-pce-inter-layer-frwk-01.txt July 13, 2006 Eiji Oki (NTT) Jean-Louis Le Roux (France Telecom) Adrian Farrel (Old Dog Consulting)

  2. Draft overview • The framework of the PCE-based path computation architecture to inter-layer traffic engineering. • Inter-layer path computation models • Single PCE inter-layer path computation • Multiple PCE inter-layer path computation • Inter-layer path control models • Higher-layer signaling trigger model • Cooperation model between PCE and Virtual Network Topology Manager (VNTM) • Became WG document in April 2006. • Change “applicability” to “framework”.

  3. Updates from 00 • Section 4.2 • Added motivations on multiple PCE Inter-Layer Path Computation (feedback form Young Lee) • Layer boundaries due to organizational and/or service management issues (feedback form Young Lee) • Scalability considerations • Section 5.2.2 • Added a sentence on higher- layer signaling trigger. • It depends on a policy at the border LSR whether the higher-layer signaling triggers a lower-layer LSP setup. • Some rewordings for the sake of clarity

  4. Next step… • Requests for feedback.
