PBB v. PBB-TE

Could I get some feedback from the list on PBB (802.1ah) v. PBB-TE (802.1Qay). Very specifically around:

1. PBB-TE's Customer side MAC learning and management capabilities.
2. PBB's direct or augmented ability to handle broadcast floods.

Also, any recommendations from the list on strong PBB-TE vendors would be appreciated.

Thanks for your feedback in advance.

Best Regards,

Babak
