Bandwidth profiles used in MEF 6.2, “Ethernet Services Definitions – Phase 3”, have significantly changed compared to those used in MEF 6.1, “Ethernet Services Definitions – Phase 2”.
Some significant changes in MEF 6.2 include:
- The bandwidth profile algorithm is generalized to support more than one flow with token sharing (prioritized bandwidth sharing) among flows.
- Per-UNI and per-EVC bandwidth profiles are no longer used.
- At egress, per-CoS ID bandwidth profiles are replaced by per-EEC ID bandwidth profiles.
This paper explains MEF 6.2 bandwidth profiles in relation to MEF 6.1 bandwidth profiles. It discusses backward compatibility, explains expanded capabilities, and offers some insight into using them.
