  1. Framework for MPLS Over Composite Linkdraft-so-yong-rtgwg-cl-framework-02.txt Ning So ning.so@verizonbusiness.com Andrew Malis andrew.g.malis@verizon.com Dave McDysan dave.mcdysan@verizon.com Lucy Yong lucyyong@huawei.com Fredric Jounay frederic.jounay@orange-ftgroup.com Yuji Kamite y.kamite@ntt.com 79th IETF Beijing China

  2. The Differences between Version 2 and Version 1 • Dramatically simplify Version 1 to seek the agreement on the CL model first in WG • Align with CL requirement draft 79th IETF Beijing China

  3. LPSs, CL Framework • Composite link consists of a set of component links that have the same end points • Composite link is used to carry MPLS traffic • LSPs, aggregated LSPs, and control plane packets • Component links may have same or different TE parameters 79th IETF Beijing China

  4. Component Link • May be a direct physical media • May be a LSP tunnel over MPLS nodes • May be a LSP tunnel via a lower layer that has GMPLS enabled 79th IETF Beijing China

  5. Composite Link in Control Plane • Act as a single logical link in IGP and IGP-TE • Signal a LSP over composite link • LDP signaled LSP or aggregated LSP • RSVP-TE signaled LSP or multi-path LSP • Signal a component link for the composite link 79th IETF Beijing China

  6. Composite Link in Data Plane • Composite link relies on its component link to carry its traffic • Traffic to component link mapping options • Control plane mapping • Data plane mapping • Management plane mapping • Component link failure • Failure notification • Traffic recovery 79th IETF Beijing China

  7. Next Steps • Welcome the feedbacks • Seeking the adoption of the CL framework draft as WG draft AcknowledgementsCo-Authorslike tothank Adrian F., Lou B., Kireeti K., Eric Gray, Dmitri P., etc. for their reviews and suggestions 79th IETF Beijing China
