Title: Generalized MPLS Signaling for Layer-2 LSPs

Generalized MPLS Signaling for Layer-2 LSPs
  • draft-papadimitriou-ccamp-gmpls-l2sc-lsp-00.txt
  • D.Papadimitriou (dpapadimitriou_at_psg.com)
  • D.Brungard (dbrungard_at_att.com)
  • M.Vigoureux (martin.vigoureux_at_alcatel.fr)

Why ?
  • Goal RFC 3473 support of L2SC LSPs
  • L2 switching architecture X,L2SC,,
    L2SC,L2SC,,L2SC,X where X Any (in
    particular, PSC)
  • Layered switching architectures (FA LSPs)
    L2SC,Y,,Y,L2SC where Y Any (in particular,
    TDM or LSC)
  • Non-Goal PW architecture ( provisioned overlays
    over PSN)

L2SC LSP and Setup Methods
  • L2SC LSP gt tunnel for Ethernet payload
    transport w/o necessarily using MPLS PWs and
    other extended p2p LDP signaling
  • Methods for e2e LSP Setup
  • direct e2e LSP setup
  • LSP nesting (FA-LSP in network)
  • LSP stitching (LSP Segment in network)
  • LSP shuffling ( GMPLS VPN)

What do we need ?
  • Not that much since max re-use of existing
    GMPLS RFCs
  • Get agreement on GPIDs e.g. GFP, X.86
  • Get agreement on label semantic(s) e.g. Port,
    Flow, VLAN
  • Get agreement on bandwidth encoding (any
    enhancement from current TSPEC ?)
  • gt Support from the working group to refine GMPLS
    procedures for L2SC LSPs ?
