Bob Snively: - copy attached “Use Of Fiber Channel Control Codes” End of Technical Agenda - Review of remaining agenda PROCEDURAL DISUSSION - Geoff Thompson: “IEEE 802 PAR Approval Process” - 802.3 HHSG, 802.3 & 802 Executive Committee approvals needed - IEEE Standards Board final approval - Need PAR materials to Executive Committee members - 30 days before March Plenary OBJECTIVES DISUSSION - Howard Frazier: Set of objectives presented, muchly discussed and modified as follows: #1 Speed of 1000 Mbps at the MAC/PLS service interface #2 Use 802.3 & ethernet MAC frame format #3 Meet 802 FR, with the possible exception of Hamming distance #4A Simple forwarding between 1000 Mbps, 100 Mbps and 10 Mbps #4B Preserve minimum and maximum frame size of current 802.3 standard #5 Full and half duplex operation #6A Support star wired topologies #6B Use CSMA/CD for half duplex access method with for support for at least one repeater #7 Fiber and if possible copper media #8 Use ANSI Fiber Channel FC-1 and FC-0 as basis for work #9 Provide a family of physical layer specifications which support: A. link distance of at least 300 meters for multi-mode fiber B. link distance of 25 meters for copper - 100 meters preferred C. link distance of at least 2000 meters of single mode fiber #10 Decide between collision domain diameter >= 50 meters or >= 200 meters #11 Support media selected from ISO/IEC 11801 #12 Accommodate proposed 802.3x flow control Motion made by C Mick and seconded by H Johnson to adopt objectives as above - FOR = 38, AGAINST =0 and ABSTAIN= 9 - motion passed CRITERIA DISUSSION - Ahmed Nouri: Target five criteria 802.3 and 802 presented and very muchly discussed - the five criteria are: #1 Broad market potential #2 Compatibility #3 Distinct identity #4 Technical feasibility #5 Economic feasibility Some notes on discussion points follow - 100Base-T PAR material to be reviewed and appropriately incorporated - need hard market data - include some fiber channel statistics - need hard participant interest data - take poll in March - scaling to be enhanced especially for CSMA/CD - emphasize uniqueness of 1000 Mbps ethernet - only one solution for each application/problem - long and short range problems - address fiber and copper - 10 times bandwidth of for 2 to 3 cost of 100Base-T/FX - collect vendor data - many customers will be able to use existing cabling - new fiber can be installed at reasonable cost Discussed PAR sheet/form to be filled out - scope, title, purpose etc The following motion was made by D Law and seconded by C Mick: - Having achieved significant technical consensus on the attached PAR and supporting material, and, - Recognizing the right of 802.3 to modify the attached PAR and supporting material, the 802.3 HSSG agrees to; - Promptly forward to the 802 Executive Committee the attached PAR and supporting material for consideration at the upcoming March Plenary meeting; - With editorial changes at the discretion of the HSSG chair. - FOR = 26, AGAINST =0 and ABSTAIN= 3 - motion passed Accompanying these minutes is a draft of the five criteria as modified after the formal interim meeting per the motion above - the original target five criteria were distributed at the meeting but not reproduced in the minutes Possible Sunday March 10, 1996 in La Jolla at 7 PM prior to Plenary Discussion of category 6 cabling standard possibility - do we want for 1000 Mbps ethernet Adjourned for the day, Friday, at 5 PM
