[Sls-slp] Results of CESG Poll on Prox-1 Data Link Pink Sheets

[Greg Kazz]

All,

Below are Bob Durst's (SIS area) comments on the proposed change to Prox-1 
data link to the frame selection rules. (see below)

We need to consider this performance issue along with any other additional 
performance issues that we feel need to be incorporated into the Prox-1 GB. 
I look forward to that discussion with you in Rome.

regards,

Greg Kazz
Chairman SLS-SLP WG

CONDITIONS/COMMENTS:

      Bob Durst (APPROVE WITH CONDITIONS):  It's really hard to review this 
without the Green Book.  I pulled the green book from the SLS site, but 
don't really know how current/complete it is.  My main concern is that the 
Frame Selection scheme in section 4.1.2.2 is complex.  I don't have a feel 
for the types and amounts of traffic that might be present in each of the 
five categories listed, and so I cannot judge how effective this scheme 
might be across the range of environments in which Prox-1 might be 
deployed.  I hoped to see some verification that this scheme would not 
result in either data or control frame starvation, but didn't see it.  I 
encourage the authors of the green book to include some analysis of this 
frame selection scheme in the updated green book (and to be really, really 
sure that it works the way that you expect it to...).
