I will vote for Option 5. -Murali -----Original Message----- From: Elizabeth Rodriguez [mailto:egrodriguez@lucent.com] Sent: Tuesday, November 13, 2001 11:05 AM To: Murali Rajagopal; Charles Monia; IPS Reflector Subject: RE: FCencap: List ALL SOF/EOF codes (Chair hat on) Let me jump back in here, and summarize as I see it: Codes from FC-BB cannot be taken intact, since there are invalid codes in that specification. Codes initially trimmed in January of this year, but Ralph correctly points out, that was prior to the formation of the FC encapsulation draft (e.g. discussion pertained directly to FCIP; did not take into consideration iFCP) That said, we can modify the current FC encapsulation draft to include other classes of service, if we so choose. We can choose to 1) Keep the table as is. Note: The current SOF/EOF codes defined in the FC encapsulation draft match the currently defined FC-BB-2 subset. 2) Add Class 1 codes Note: FC-MI (technical report, not a standard) does not support Class 1. Note2: Practicality of Class 1 over IP questioned. 3) Add Class 4 codes Note: Class 4 work is ongoing, but SOF/EOF codes currently defined for class 4 unchanged. 4) Add both class 1 and class 4 codes I would like to solicit input from everyone on what codes people feel should be included in the FC encapsulation draft. Note: Drafts following FC encapsulation may restrict classes of service that draft supports.

FC-MI should be kept out of this. If we simply accept to adopt the SOF and EOF codes listed for BB-2 the problem is solved. FYI, BB-2 only supports Class 2, 3, and F codes. I don't see why we are making a big deal about this. -Murali -----Original Message----- From: owner-ips@ece.cmu.edu [mailto:owner-ips@ece.cmu.edu]On Behalf Of Charles Monia Sent: Monday, November 12, 2001 3:33 PM To: IPS Reflector Subject: RE: FCencap: List ALL SOF/EOF codes Hi Folks: > David's observation is correct.

The last time I checked, the FC-MI spec was not a "standards track" document (to use IETF terminology). If that's still the case, is FC-MI's prohibition of class 1 a sufficient basis for precluding class 1 support in the encapsulation spec?
