[LARTC] Bandwith Aggregation

[LARTC] Bandwith Aggregation

[Felipe Herrera]

I am working on my Diploma Thesis on Computer Science Engineering.

The main idea behind of my work is to make it possible to have
a Linux box combining multiple ISP/network connections together
providing a single connection with an aggregated bandwith.

I have been surfing the Internet and I haven't found anything
like that running on Linux. I would like to implement it using
iproute 2 tools, but I don't really know it it is possible now.

By the way, I have seen that in the LARTC jobs list there is
one called  "Multipath routing".
Has anyone any idea of what is it about?

   Thank you in advance.

Yes, I suppose this is what you want - Equal Cost Multipath Routes.
This issue is discussed here almost every few days :( so for the start
just -READ THE ARCHIVES- and you will find everything you need.

IMHO the idea is well known but sometimes makes some troubles
(I have such a setup with 3 ISP and no BGP just plain bandwidth aggregation),
and there were much more examples in last year :) on the list.

For the start read my posting from 15th Oct 03 as an working example.

 I have just a question about your script (I found it on the archives)...

I have 3 DSL lines, linke you, but all of them are conected to a switch and 
then to my eth1 interface on wich I have 3 public ip's and 2 public ip's 
ranges, let me try to draw it.


                                        DMZ Zone
                                              |
                                          eth3
DSL1\                                   |
DSL2 - - Switch - eth1 [Linux Box] - eth0 -Switch - LAN
DSL3 /                                  |
                                           eth2
                                              |
                                          LDMS

What I need is to send all SMTP/POP3 traffic throught DSL1, and the rest of 
traffict througth a load balancing between DSL2 and  DSL3 giving preference 
on DSL3 over DSL2 (moreover because DSL3 it's a 2Mbits simetric line with the 
local cable company, and DSL2 it's a ADSL 256Kbit), but if DSL1 fails, the 
SMTP/POP3 traffic should go out by any of the other interfaces, also if DSL2 
or DLS3 get out, rest of traffic should go by DSL1.
 
The LDMS link its used only for IPSec tunnels and should never be user for 
nomal traffic.

DSL1 -> ADSL 256 with a /30 public range on the ethernet side.
DSL2 -> ADSL 256 in bridge mode, so I have it's public IP on my side.
DSL3 -> Cable 2Mbit with a /30 public range on the ethernet side.

By now I only have setup a simple link with it's gateway using DSL1 for all 
traffic, and I'm been unable to do that if a ssh conection (for example) 
reach eth1 by DSL3 or reach eth2 by LDMS and get answered by the same link.

May someone give me a hit on what I'm doing wrong or what must I do to get it 
working.

Best regards

I forgot to mention that I'm running Debian Sid, with kernel 2.6.1 patched 
with NANO patchs and iproute2 with HTB support (but by now I'm not interested 
on clasiffiying traffic, that will be later)
