  1. Requirements for GMPLS-based multi-region and multi-layer networksdraft-shiomoto-ccamp-gmpls-mrn-reqs-00.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 61st IETF Washington DC November 2004

  2. LSP Region • Based on Switching Capability: PSC, L2SC, TDM, LSC, FSC "LSP hierarchy with generalized MPLS TE," <draft-ietf-mpls-lsp-hierarchy-08.txt> Sept. 2002. 61st IETF Washington DC November 2004

  3. FXC Router EXC PXC Multi-region network No FA Triggered FA Pre-Provisioned FA FSC LSC TDM PSC 61st IETF Washington DC November 2004

  4. LSR OXC Plain node and Hybrid node • Plain node (Single ISC) • Hybrid node (Multiple ISC) LSR PXC PSC LSC PSC Physical view Link-state view HN PSC 61st IETF Washington DC November 2004 PSC+LSC

  5. Major Changes • Two I-Ds are generated from “Generalized MPLS Architecture for Multi-Region Networks” <draft-vigoureux-shiomoto-ccamp-gmpls-mrn-04.txt>,2/2004 • “Requirements for GMPLS-based multi-region and multi-layer networks,” <draft-shiomoto-ccamp-gmpls-mrn-reqs-00.txt>, 10/2004 • “Generalized Multi-Protocol Label Switching (GMPLS) Protocol Extensions for Multi-Region Networks (MRN) ,” <draft-dimitri-ccamp-gmpls-mrn-extensions-00.txt>, 10/2004 61st IETF Washington DC November 2004

  6. Summary of I-D • Motivation • Multi-region TE • Multi-layer service • Key concepts • ISC (Interface switching capability) • Single ISC and multiple ISC node • FA (Forwarding adjacency) • Triggered signaling • Virtual FA • VNT (Virtual network topology) • Multi-layer service network 61st IETF Washington DC November 2004

  7. Summary of I-D (Cont’d) • Requirements • Scalability wrt # of nodes, TE-links, LSPs, and regions • FA utilization (FA release and setup, Virtual FA) • FA LSP attribute inheritance • Verify data plane of FA • Disruption minimization • Tradeoff between efficiency and stability • Computing path w and w/o triggered signaling • Handling both plain and hybrid nodes • Advertisement of adaptation resource 61st IETF Washington DC November 2004

  8. Virtual network topology (VNT) VNT 2 VNT 1 61st IETF Washington DC November 2004

  9. Application example • Multiple service/layer networks over a single server network • Inter-layer TE Layer 3 networks Layer 2 networks Layer 1 networks Common Optical NW 61st IETF Washington DC November 2004

  10. Layer and Region • Region • Control plane: Based on switching capability • Layer • Data plane: Based on client-server relationship • E.g,PSC over TDM, PSC over LSC, PSC over PSC 61st IETF Washington DC November 2004

  11. Next Actions • Adopt as WG document • Requests for review/feedback 61st IETF Washington DC November 2004
