Scope and Objectives

• Provide a framework for MPLS-TP-based
  survivability, introducing the functional
  architecture
• The general description of the functional
  architecture is applicable for both LSPs and PWs.
  
• Detailed consideration for the protection of PWs
  in MPLS-TP networks will be covered in a separate
  document. We expect that this draft will probably
  be worked on within the PWE3 working group.
• Highlight areas where new work is required.
• Use the recovery terminology defined in RFC4427
  as normative. Note that RFC 4427 draws on
  G.808.1.
• Refer to the requirements specified in RFC 5654.
• Use similar principles of the recovery schemes as
  those defined and analyzed in RFC 4427 and RFC
  4428.
