Plan for interim (from July)g Research following topics:
n Frame size limitations of: n Existing equipment – below MAC (elasticity buffers, block
coding, delimiters)n Existing equipment – above MAC (FIFO, fabric)n Links with FEC (EPON)n Rate compensation (WAN PHY, EFM Copper)
n Effect of increased overhead on performance, especially in aggregation
n Feasibility of reducing MTU of installed base of clientsn Tutorial on 802.1ABn Straw man frame format modifications
g Finalize PAR/5 criteriag Draft TF objectives

IEEE-SA Standards Board Bylaws on Patents in Standards6. Patents
IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard. This assurance shall be provided without coercion and prior to approval of the standard (or reaffirmation when a patent becomes known after initial approval of the standard). This assurance shall be a letter that is in the form of either
a) A general disclaimer to the effect that the patentee will not enforce any of its present or future patent(s) whose use would be required to implement the proposed IEEE standard against any person or entity using the patent(s) to comply with the standard or
b) A statement that a license will be made available without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably free of any unfair discrimination
This assurance shall apply, at a minimum, from the date of the standard's approval to the date of the standard's withdrawal and is irrevocable during that period.
Approved by IEEE-SA Standards Board – December 2002

Inappropriate Topicsg Don’t discuss licensing terms or conditions
g Don’t discuss product pricing, territorial restrictions or market share
g Don’t discuss ongoing litigation or threatened litigation
g Don’t be silent if inappropriate topics are discussed… do formally object.

Concerns raised in Julyg “Is this absolutely necessary?”
n Alternativesn Exclude .3 support from .1ad & .1AE standardsn Handle on bootleg basisn Require .1 SAR functionn Reduce client MTU to make room for added headers
n Orn Expand frame size
n Possibly use discovery to enable larger frames on some links
g Backward compatibilityn Location of QTag, CSMA/CD fairness,
g Additional space used only for headers, not datag QoS/efficiency impact
