Re: [OPSAWG] [OPS-AREA] Present day reality of COPS-PR
Hi,
These claims were gathered by me from co-workers familiar with
COPS-PR.
I have not checked any of the claims.
The most interesting to me are the claims of deployment in FIOS,
FT-Orange, and Comcast.
We should seek out people knowledgeable about the technologies used in
these networks, and ask about COPS-PR.
Does anybody have contacts within the IT departments of these
companies?
