Re: Deployments of Provider Backbone Bridging (PBB)

[Etienne-Victor Depasquale via NANOG <nanog () nanog org>]

I've had two private replies, both of which suggest that
PBB has little to no share in the overall pie of the aggregation technology
space,
nor in the overall pie of the core technology space.

However, a third correspondent states that Bard (Google's "Chat-based AI
tool") claims that
PBB is deployed by AT&T, Verizon, China Mobile, Deutsche Telecom and
Comcast.
This correspondent warns that Bard "could be hallucinating" :)

Any further data points/insight would be appreciated.

Cheers,

Etienne
