Anybody have a good link for a white paper on frame relay traffic shaping?
Interested in both theory and configuration
thanks

Guys,
What are the parameters that I should configure on the router to control the
bandwidth usage of the user on a frame-relay configuration.
For instance, the user has T1 line and I need to provide him only 512k. Is
it the CIR, BE, BC, MINCIR, and traffic rate only ?
and how do I calculate them
A presentation at Melbourne Networkers suggested the following guidelines when
configuring frame relay traffic shaping (for data only, not voice).
This assumes that you remote site has a lower access rate than the central site
(or the same access rate).
At remote:
Set CIR to match line speed
G'day All,
I have recently been trying to tweak some FRTS parameters and playing around
with Tc. The Cisco site states that Tc should be 125ms max, and I have found
this to be a bit large for the majority of our installations. What I
generally use as my defaults are Tc=60ms for normal data sites
Got a question on traffic shaping. Have a couple high speed frame pipes
going into data center/server farm locations. Speeds are 9.264MBPS at
datacenter, 6.176MBPS going into primary server farm, and 4.632MBPS going
into a less-used server location.
Remote sites are running from 128K to 1.544Meg.
The easiest way to do this is to only configure the CIR and Line speeds and
let the rest default.
Example commands -
int s0
frame-relay traffic shapping Enable FRTS on the interface
frame-relay class ExampleClass Shape as defined in map class

Wizards,
As the FRTS has been brought up here, I really want to
take this chances to get some help from you in
understanding this.
When we enable the 'frame-relay traffice shaping'
under the inferface, we start using frame-relay
traffice shaping not generic shaping, right?
in the map-class of
As far as I know, they are both equal. So you can do it by either way.
Please someone correct.
Thanks a lot guys,

Here is a good link to a page that explains Ciscos frame relay traffic

I'm not very familiar with generic traffic shaping.
But, at first glance it looks like it is basically the same thing as frame
relay traffic shaping except that it does not dynamically change based on
network congestion because there is no method set up to notify the router of
any conge

Please check my logic:
My Bc is 8,000 bits
My Be is 16,000 bits
My CIR is 64 Kbps
If I send 1 burst of 56,000 bits then 4 bursts of 4,000 bits, after the 4th
burst of 4,000 bits I will be able to burst again but not before that.
Correct?

looking at doing is using frame-relay traffic shaping with

Apparently if the byte-count is too high then the router will
Bruce;
Your Idea is as good as any.
The idea is to drop back to your CIR in times of congestion to avoid
dropping frames (and incurring re-transmits)
however, with 0 cir, there is no logical point to set it.
Set it lower and hope you drop less frames.
Personally, on a zero cir net, I would bag t
Bruce,
As a first cut you may want to set CIR equal to port and MINCIR to half that
so when you do get BECNS the router will throttle back (25% of current
bandwidth with every BECN no lower then MINCIR is the algorithm).
This will give some sense that if the cloud or pvc is congested you will

That's a good point, however, if you setup traffic shaping with 0 as the min
rate and any speed as your max rate (make it 128 or 258 or 1.544 if you
want), when there IS congestion in the cloud, this would at least allow the
router to scale back the output so that there may not have to be as many
Hello,
Is there a way of simulating a FR network (hub&spoke) to "fail" without
traffic-shaping config?
On CCO, all they have is examples of traffic-shaping configs that actually
work.

Config a router to be a frame switch. Make the hub router's connection to
the frame switch 1554k. Make a spoke router's connection to be 64K. Then
blast traffic to him. I believe you will flood the frame switches egress

32000 is your average speed, it is what the router will transmit at if

The router assumes 1/2 average speed for CIR, so it will back off to 16000
