Licensing information, comments, notes or URL for further information:

Nortel Networks may seek patent rights on technology described in a document
which Nortel Networks contributes for use in IETF standards discussions or
standards track specifications. If such patented technology is essential
for the implementation, use, and distribution, of an IETF standard, Nortel
Networks is willing to make available nonexclusive licenses on fair,
reasonable, and non-discriminatory terms and conditions, to such patent
rights it owns, solely to the extent such technology is essential to comply
with such IETF standard.

Also, to the extent that an essential patent(s) is subsequently identified,
Nortel Networks is willing to make available a nonexclusive license under
such patents, on fair, reasonable, and non-discriminatory terms and
conditions. Similarly, when and if patent applications are subsequently
issued, and determined essential to the practice of an IETF standard, Nortel
Networks is willing to make available nonexclusive licenses under such
patents, on fair, reasonable, and non-discriminatory terms and conditions.
The terms apply to those patents for which Nortel Networks has the right to
grant licenses.
