Re: UNI end-to-end sessions



Hi,
 
As you might know, the NNI interoperability test at the Supercomm 2002 has been cancelled.
But, you can still refer to the document (oif2002.025) _just_ for your reference.
(It's under heavy discussion among the principal members in the OIF.)

Hi Sudheer, all,

I think the work is actually part of the Supercomm NNI work effort
(there is no private NNI effort within OIF). For folks involved with OIF
and Supercomm NNI, see OIF2002.025, Section 7.4, which clearly includes
the facility to transport UNI-specific information (such as TNA) from
source UNI to destination UNI.

This is not part of the IETF GMPLS documents yet. I view the GMPLS work
in IETF as laying a foundation for using IP-based protocols. For
example, the OIF and ITU-T may use these protocols to extend the
capability to support UNI-based, and E-NNI-based signaling and routing.
In fact this is exactly what was done for the UNI.

FYI, I've also added oif-signal@oiforum.com to the cc: list
