Re: [Teas] IPR Disclosure Infinera Corporation's Statement about IPR related to draft-ietf-teas-interconnected-te-info-exchange

Adrian/All,
    Please discuss the disclosure and additional information provided by
Rajan to the group as you see fit -- both now and during LC. 

Without regard to contents, I note that IPR was also been disclosed on
"The Backward-Recursive PCE-Based Computation (BRPC) mechanism",
RFC5441,  back in 2007.

Such a mechanism is not proposed or even mentioned in this document, so readers may draw their own conclusions about the relevance of the disclosure.
