Recent operational experience choosing between PBB-TE, MEF9+14, VPLS or T-MPLS ?

[Francois Menard <francois () menards ca>]

I'm embarking on a new project which involves a large scale MAN network where ultimately, the objective is to carry 
QinQ, while at the same time delivering services over IPv6.

The objective is to support jumbo frames on all interfaces, at least to carry QinQ standard-size ethernet frames, but 
ideally as large as possible

There seem to be 4 approaches to do this.

a) The IEEE PBB-TE approach - but little implementations.
b) The MEF9+14 approach, mature, but manual provisioning
c) The VPLS approach, concerns with too much manual provisioning.
d) The T-MPLS approach, concerns with maturity

The objective is to support the functionality not only in the CORE, but also on cost effective multi-tenant & redundant 
customer CPEs.

I have not seen a, or b or d supported in a low-cost customer CPE.

I am currently favouring c, for reasons of maturity and wide implementation, but may be missing on recent progresses in 
the b) land.

Any thoughts ?

Any published IETF material on the topic ?
