RE: Link Status thoughts




Osamu,

I believe that no one is proposing (1) at this time. It was in Shimon's
earlier proposal but has been replaced. I have mentioned (2) as a 
possibility but I prefer (3).

Pat

Pat,

In X-PCS/XGXS, I have seen the following fault indicator candidates:
(please correnct me If I am listing wrong names)

(1) send N fault indicators and N /A/K/R/ Idles alternately (Shimon, Rich)
(2) replace /A/ with the fault indicator (Pat)
(3) put the fault indicator in after each /A/ (Pat, Shimon)
(4) send a fault indicator once every N /A/K/R/ Idles (Rich, Osamu)

You can find Rich's 10GFC proposal in 
ftp://ftp.t11.org/t11/pub/fc/10gfc/00-488v0.pdf

Best Regards,
Osamu
