MEF 10.1.1 Amendment to MEF 10.1 Ethernet Services Attributes Phase 2

Details:

This Amendment to MEF 10.1 is intended to replace parts of section 6.9 (6.9, and 6.9.1 through 6.9.6) and revise related material in sections 2 and 8.4.

NOTE: THIS STANDARD HAS BEEN SUPERSEDED.

The amendment makes changes as follows:

• Update the Frame Delay attribute to:
  • Add the definition of Frame Delay Range parameter
  • Add the definition of Mean Frame Delay parameter
• Clarify for Point-to-Point EVCs that objectives apply to one direction of transmission at a time
  • Makes point-to-point and multipoint treatment consistent
• Rename FDV as Inter-Frame Delay Variation for clarity Updates to other technical content of MEF 10.1 are out of scope. One key difference is in the treatment of Point-to-Point EVC Performance as a special case of Multipoint EVC, where separate populations of Service Frames delivered between each ordered pair of UNIs are evaluated against the performance objective. Another difference is the treatment of the case where no qualified Service Frames are delivered between one or more ordered pairs of UNIs during the evaluation interval. The performance is designated “Undefined”, but also designated as compliant with the associated objective.
