Introduction
• Proposed text is in 01/504 – available mid-week
• Additional adjustments to d0.8 as markup to editor editorial
• Addresses open actions in 01/374r8
• Covers the topics mentioned on next page
• May need an additional spin to align with 01/410
• If approved, this is to be
– applied to d0.8
– 01/485r4 is required
– 01/488r1 is required

8.8 Probe
• Fixed timeout not acceptable for EPS DEVs
• Require sending DEV to use EPS
information, EPSTime & EPSNext to
determine allowable time to resend probe
• Allow sender to switch EPS DEV to ACTIVE
to speed up the exchange.
• Allow sender an aggressive resend
