  1. MRN document set Requirements draft-shiomoto-ccamp-gmpls-mrn-reqs Analysis draft-leroux-ccamp-gmpls-mrn-eval GMPLS Protocol Extensions draft-papadimitriou-ccamp-gmpls-mrn-extensions 62nd IETF Minneapolis February 2005

  2. Requirements for GMPLS-based multi-region networks (MRN)draft-shiomoto-ccamp-gmpls-mrn-reqs-01.txt Kohei Shiomoto: shiomoto.kohei@lab.ntt.co.jp Dimitri Papadimitriou: dimitri.papadimitriou@alcatel.be Jean-Louis Le Roux: jeanlouis.leroux@francetelecom.com Martin Vigoureux: martin.vigoureux@alcatel.fr Deborah Brungard: dbrungard@att.com Eiji Oki: oki.eiji@lab.ntt.co.jp Ichiro Inoue: ichiro.inoue@lab.ntt.co.jp Emmanuel Dotaro: emmanuel.dotaro@alcatel.fr

  3. Major changes (00->01) • Some clarifications • VNT (see next slides) • Node categories (see next slides) • Vertical vs Horizontal integration • Multi-region signaling 62nd IETF Minneapolis February 2005

  4. VNT: Virtual Network Topology • TE based on dynamic reconfiguration of VNT • Optical-layer provides VNT for packet-layer • VNT is re-configured by LSP setup/teardown. • Optical-LSP is routed over the fiber topology. Traffic demand New VNT Current VNT VNT 2 VNT 1 62nd IETF Minneapolis February 2005

  5. Node categories • Multiple switching capable nodes: simplex versus hybrid • A simplex node • single switching capability per interface, but can comprise of interfaces with distinct switching capabilities • advertises several TE Links each with a single SC value as part of its ISCD sub-TLVs. • A hybrid node • multiple switching capabilities per interface, and interfaces of the same hybrid node may have different multiple switching capabilities • advertises at least one TE Link containing multiple ISCDs with different SC values (at least one per supported SC value per interface). TDM 62nd IETF Minneapolis February 2005 PSC

  6. Evaluation of GMPLS Protocols against Multi Region Networksdraft-leroux-ccamp-gmpls-mrn-eval-00.txt Jean-Louis Le Roux (France Telecom)Deborah Brungard (AT&T)Eiji Oki (NTT) Dimitri Papadimitriou (Alcatel) Kohei Shiomoto (NTT) Martin Vigoureux (Alcatel) IETF 62, Minneapolis 03/08/2005

  7. Evaluation Result

  8. Generalized Multi-Protocol Label Switching (GMPLS) Protocol Extensions for Multi-Region Networks (MRN) draft-papadimitriou-ccamp-gmpls-mrn-extensions-01.txtJean-Louis Le Roux (France Telecom)Deborah Brungard (AT&T) Kohei Shiomoto (NTT) Dimitri Papadimitriou (Alcatel)Martin Vigoureux (Alcatel) IETF 62, Minneapolis 03/08/2005

  9. From last version (v00.txt) • Editorial revision • Coverage • advertisement of interface adaptation capability (internal termination capability) • multi-region signaling • Multi-region signaling • Exclude Route (XRO) for excluding set of one or more SC from a link supporting multiple SCs • Explicit Route (ERO) for including a specific SC from a link supporting multiple SCs

  10. Next revision • Cover signaling of virtual Forwarding Adjacencies

  11. Conclusion • Requirement document • Pretty stable • ready for WG status • Evaluation document pretty stable • concentrate discussions on protocol applicability • WG status ? • Solution document to be progressed
