Hi Madhuri

yes its possible,

you can make all link one big pipe and share the load  equally

to do this you need to add some patches to you kernel

you did not mention what distro are you using

iam using redhat 9.0, with multiple links working fine


best of luck

[LARTC] bandwidth shaping over multiple WAN links

[madhuri]

Hi,

We have three WAN links each of capacity 2 Mbps.

There is a one linux box per link which is used for NAT and firewall. So
I have three linux boxes and three WAN links to talk to the internet.

We want to do bandwidth shaping over these three links. I know
individually we can do bandwidth shaping for a particular WAN link using
linux tc tool. I can repeat the same bandwidth shaping commands for
other two links also. However it would be better if I can treat three
links as one big WAN pipe and do the bandwidth shaping for all of them
at one place. Is it possible?

I am just thinking aloud and not sure if that is possible or not.


Thanks,
Madhuri

We are using redhat 8.0, however we can switch to redhat 9.0 if required.

So you have one linux box with multiple ethernet cards each connected to a
seperate WAN link and you are doing traffic shaping over these links?

I have read about load balancing with 'teq' or something like that with
linux. Are you refering to that?

Re: [LARTC] bandwidth shaping over multiple WAN links

[hare ram]

Hi

Yes, you can achive the same with  RH 8.0 also.
yes iam using multiple ethernet  for internet side ( backbone side)
and one ethernet for LAN side
and loadbalancing all the links..

iam refereing

http://www.ssi.bg/~ja/nano.txt

with the help of  julian, i have achived this for load balancing

for shaping the b/w best places are

www.lartc.org
www.docum.org ( stef)

will help you lot

best of luck

RE: [LARTC] bandwidth shaping over multiple WAN links

[S Mohan]

I've read this based on this post. It deals with static IP scenario for both
links. If we have two DSL links on dynamic IP and pppd inserts default
route. If we run pppd/ppoe on two links and want to load balance between
these links, how do we get pppd to add these links as alternate default
routes with weights? Or do we have to do this explicitly with ppp-up?

It also depends if you want to shape download or upload.  If you want to shape 
upload, you have to realize that you can only use 1 link.  For download, you 
can use 3 links but only if you NAT and you have a lot of connections so you 
can load balance the different connections (like http traffic).  An ftp 
download, will only use 1 link.
This all to say that's not so easy to determine what will be the maximum 
bandiwdth a class can get.  And that's one of the parameters you need to 
create a good tc setup.  But you can create a tc setup that can shape the 3 
links in both directions.  Even if this shaping is not perfect, it still 
beter then not shaping at all.

Can you provide some pointers on how to do this, especially load balancing?

Try the nano HOWTO, posted on Julian Anastasov's site:

  http://www.ssi.bg/~ja/nano.txt

I would recommend searching the archive for previous discussions of this
question.  It comes up about in longer discussions twice a year or so.

  http://www.google.com/search?q=site%3Amailman.ds9a.nl+nano+howto

Good luck,
