'III'. IETF Document or Other Contribution to Which this IPR Disclosure Relates
RFC4656 ("A One-way Active Measurement Protocol (OWAMP)")
'IV'. Disclosure of Patent Information i.e., patents or patent applications required to be disclosed by Section 6 of RFC 3979
A. For granted patents or published pending patent applications, please provide the following information:
- Patent, Serial, Publication, Registration, or Application/File number(s)
Date: Not known
Country: Probably US
Notes: Several years ago I heard that Hewlett Packard had a patent on cross-net latency
measurements that used GPS time sources. (Given that HP split itself in two,
the patent, if it exists might be owned by Agilent.)
I have no idea whether I was hearing (or mis-hearing), much less any details on
This RFC might suggest something that, if implemented, might impinge on that
patent (assuming that it exists.)
I hate to be so vague, but I don't have anything more concrete. I was working
on some net measurement tools myself (e.g.
http://www.cavebear.com/fpcp/fpcp-sept-19-2000.html ) and remember that I and
several others avoided using GPS time measurements for transit-time measurements
precisely because of the existence of this putative patent.
By-the-way, as for question "B" below, I have no idea whether what I heard
about was an unpublished application. But it was several years ago so any
period of non-publication ought to have expired by now.
B. Does this disclosure relate to an unpublished pending patent application?:
- Has patent pending
