Updates

• Expanded discussions on Requirements for
  Inter-AS MPLS TE across Multiple SP Admin domains
  (section 5.2)
• Confidentiality across the transit AS
• Hidden explicit paths across transit AS
• TE-LSP Cost for optimal inter-AS path computation
• Trouble-shooting
• Policy-control
• Enforcement at the boundaries
• Attributes in RSVP-TE Session or Fast-Reroute
  objects
• Bandwidth admission enforcement
• Interconnect policies neighbor AS/HE AS, DS-TE
  ltCT, Pgt, etc.

Next Steps

• The following areas are being considered in the
  -01 revision of draft-ietf-interas-mpls-te-req
• Considering to include the ability of specifying
  explicit nodes across the transit as
• Adding accounting requirements for capacity
  management, policy enforcement and billing
  purposes
• Considering to bring in a separate section to
  address further requirements of maintaining e2e
  TE-LSP integrity upon potential changes along the
  transit ASes
• Notification to HE TE-LSP Tunnels
• Re-optimization
• Preemption
• Others
