Yes sir I do have that book; I will put my nose in it tonight to see if
something new clicks on for me. Thanks for pointing that out.
A kind sir named Rahul posted the below to me this morning on the
IPexperts board.
"Use following ex depending upon traffic type that VCs will be carrying
& I m sure it will be clearly mentioned in any of the requirement if not
specified than I assume data:
For Data
----------
If you wish to burst your traffic at AR rate in first interval than use
following calc :
Be = AR - (Bc x 8)
For Voice
----------
Its simple. Does burst traffic in FR network provides guarantee delivery
the answer is NO. Hence Be for Voice traffic will always be "0"."
Thank you,
scott

Do you have access to the Solie book, "CCIE Practical Studies"? There
is a pretty good explanation of these on page 366.
"Frame-relay be out bps - This is the number of extra bits remaining
from the previous bursts that will be sent on the first interval. This
should not exceed the port speed of the remote router."

This is my understanding.
Tc = Bc/CIR
Bc = CIR/8 (this is for 125msec) or CIR/10 (this is for 10msec - VOICE)
Be = ????????????
I have seen an opinion in that (Be = port speed minus CIR)
So if in the lab I have a task in which the CIR is less than the AR
should I use the above formula for Be or should I use another formula?
http://www.cisco.com/warp/public/125/traffic_shaping_6151.html
"Configure Be only if the Frame Relay CIR value is less than the AR. For
PVCs carrying voice packets, the Be must be set to zero to ensure best
possible voice quality."
Thank You,
Scott
