Re: [RE] Updated paper



David:

In section 10.1 of your rate based scheduling proposal you equate shorter
latency with higher bandwidth utilization (or at least reservation).  It
seems to me that in many application areas used in the home that the latency
time needed may actually be inversely proportional to the bandwidth.  High
bandwidth applications like HD video need a bounded latency to ensure
adequate buffer sizes and proper delay before decoding starts but the
absolute value of the latency is not as important.  Some low bandwidth
applications, especially interactive ones like corroborative music, need
very low latencies to properly sync all of the performers.  It would seem a
waste to reserve a lot of bandwidth for the low bandwidth applications that
need low latency that would then preclude higher bandwidth applications from
running due to maximizing the reservation limits.

All,

I have posted an update for tomorrow's meeting.
This can be found at:
  http://dvjames.com/esync/dvjRate2005Aug30.pdf

I assume Michael will move this to the group's
IEEE web pages.
