Licensing
See Text Below for Licensing Declaration
Licensing information, comments, notes, or URL for further information

If technology in this document is included in a standard adopted by IETF and any claims of any
Cisco patents are necessary for practicing the standard, any party will have the right to use any
such patent claims under reasonable, non-discriminatory terms, with reciprocity, to implement and
fully comply with the standard.

The reasonable non-discriminatory terms are:

If this standard is adopted, Cisco will not assert any patents owned or controlled by Cisco against
any party for making, using, selling, importing or offering for sale a product that implements the
standard, provided, however that Cisco retains the right to assert its patents (including the right
to claim past royalties) against any party that asserts a patent it owns or controls (either
directly or indirectly) against Cisco or any of Cisco's affiliates or successors in title or
against any products of Cisco or any products of any of Cisco's affiliates either alone or in
combination with other products; and Cisco retains the right to assert its patents against any
product or portion thereof that is not necessary for compliance with the standard.

Royalty-bearing licenses will be available to anyone who prefers that option.

Note: The individual submitting this template represents and warrants that he or she is authorized by the Patent Holder to agree to the above-selected licensing declaration.
