Title:
|
MEF 23.2.2 Satellite Performance Tier
This amendment makes the following changes to MEF 23.2 :
• Changes are made to Section 8.6.1 of MEF 23.2 to generalize certain requirements to apply to CoS Names instead of just CoS Labels.
• A new normative section is added that defines a set of token sharing Bandwidth Profile models. These models allow for multiple Bandwidth Profile Flows in an Envelope thus enabling token sharing among the Bandwidth Profile Flows.
• New terms are added to the Terminology table of MEF 23.2
• A new appendix is added that describes use cases for the defined token sharing Bandwidth Profile models.
