[LARTC] Bandwidth control using Linux or other router

[LARTC] Bandwidth control using Linux or other router

[Ming-Ching Tiew]

I have a requirement to be connected to a T1/E1
leased line WAN. Because of QoS issues, I am
considering these options :-

1. Purchase a router which has some form of 
   bandwidth management - this would be 
   expensive, rite ?

2. Purchase a low end router with 1 lan 1 wan,
   and connects a dual LAN linux before it.

   Will this additional hop slow down anything?

3. Purchase a supported T1/E1 interface cards
   and plug it into the Linux box.
   
   This could be a problem for me because of
   support issues. What if it does not properly?
   What if there are problems with the card
   or the drivers ?

Any recommendation?

Hello all,

 : 1. Purchase a router which has some form of bandwidth management - this
 :    would be expensive, rite ?

You have to decide what is expensive for you.  Time, money, expertise,
control, or not having a software/networking vendor to vilify.

 : 2. Purchase a low end router with 1 lan 1 wan, and connects a dual LAN
 :    linux before it.  Will this additional hop slow down anything?

Yes.  But maybe not significantly enough to be a problem...depends on your
pipe and usage on that pipe.  Remember, it's ideal to perform traffic
control on the bottleneck itself.  Regardless, I'd suggest option 3 or
option 1, depending on your answer to your own question in 1.

 : 3. Purchase a supported T1/E1 interface cards and plug it into the
 :    Linux box.

I recommend the Sangoma WAN cards.  I've been using them for at least 3
years under linux, and they are well supported by Sangoma and the linux
community (you'll see the driver in the distribution).

  http://www.sangoma.com/

I've had exactly one problem with the wanpipe/wanrouter software, and it
had already been identified and fixed by the time I had filed the bug
report with Sangoma.

 :    This could be a problem for me because of support issues. What if it
 :    does not properly? What if there are problems with the card or the
 :    drivers ?

You won't have problems with support for Sangoma's cards in the kernel nor
technical support from Sangoma.

I am surprised because I am quite inclined towards option 2. Haha.

Regarding Sangoma solution, what Linux kernel version they are
supported on ? I would need 2.4.20 or there about.

Rgds.

Hello there again,

Perhaps I wasn't as clear as I could have been.  Support for their cards
has been a part of the linux kernel distribution for quite some time.
