Another important factor is where the sites are located.   congestion is most
prevelant in the
NNI's.

Hi,

if there are one central site and three remote sites. all the remote sites 
need to connect to the central site. now I need to decide the access circuit 
and port speed for the central site. the CIR requirement are following:

Remote site A: 14M

Re: frame relay question [7:34090]

2002-02-01 Thread John Neiberger

Where did you get 28MB from?  In your original email you said that each
location needs 14 MB.  Are you taking into account that the circuit is
full duplex and adding the input and output rates together? If so, that
is not necessary.  

If you have three remote sites with 15MB fractional DS3 frame relay
service (assuming you can get that from your provider) then you only
need a single DS3 at your central location, again assuming that your
provider offers a frame relay DS3.

RE: frame relay question [7:34090]

2002-02-01 Thread Graham, Darel R.

In order to accomodate your needs you could
have each remote site have a pvc built over
each of the T3s. This removes the need or 
worry over the physical circuit. 

How about using a carrier that can do frame relay
at the ends and IP or ATM in the middle??

At the remote ends how do you plan to get that 
much traffic out? The best bet would be a T3 
at the remote sites too.

well, if you really need 90mb, then the best thing to do would be to inverse
mux on your end and have the telco muc them on yoru end... (2 ds3's)

then you would have a 90mb frame pipe to bring remote site into.

thanks for your reply. sorry that I didn't make my question clear.

Actually what I want to know is that, if the port speed requirment to every 
remote site is 28mb, then the aggregate port speed requirement in central 
site would be 84mb. should I order 2 T3 access circuits or 3 at the central 
site? if 2, how can i config the 3 DLCI across the 2 T3 circuits? because 
there would be 1 DLCI needed to be split between the 2 T3 circuits.

thanks again!

if there are one central site and three remote sites. all the remote sites
need to connect to the central site. now I need to decide the access

Some telcos have some basic oversubscription requirements, designed more so
that they can sell you more bandwidth than as a real practical requirement.

Here in California, for example, the local telco permits no more than a 2
for 1 oversubscription.

So if you have 20 spokes, each at 256K CIR, then you MUST have a minimum
2.56 megabit CIR at your center ( fractional DS3 or ATM ), for example.

I believe the reasoning is that the telco does not want a lot of calls
complaining about their circuits when the problem is overutilization of
bandwidth. And they want to sell you more, of course. ;-

Re: frame relay question [7:34090]

2002-02-01 Thread Yatou Wu

14MB is the CIR and 28MB is the port speed. Normally we assume that the port 
speed should be double of the CIR, which might not be right.

for the remote site, if CIR is 14MB(actually what we can get is 15MB), the 
port speed we can get from the vendor is 45MB. so every remote site needs a 
DS3 access circuit.

the numbers here are all assumptions. but it presents a question I have. for 
the central site, the aggregate port speed is less than 2 DS3, but how can 
you assign those DLSIs to the 2 DS3 access circuits?

Where did you get 28MB from?  In your original email you said that each
location needs 14 MB.  Are you taking into account that the circuit is
full duplex and adding the input and output rates together? If so, that
is not necessary.

If you have three remote sites with 15MB fractional DS3 frame relay
service (assuming you can get that from your provider) then you only
need a single DS3 at your central location, again assuming that your
provider offers a frame relay DS3.

Re: frame relay question [7:34090]

2002-02-01 Thread Chuck Larrieu

each remote has two DLCI's - one to the first T3, one to the second. you use
load sharing to balance traffic across the links.

OR

a couple of folks have suggested muxing multiple T3's at your host site. In
the environment you describe, you should have no problem getting your telco
to work with you. doing so would eliminate the need for two pvc's from each
remote.
