Hi All,
I am currently researching on doing high availability and load balancing
with a couple of Linux servers, most specifically doing service takeover on
top of Heartbeat.
The scenario is:
- 2 DSL lines from a single provider
- 1 Broadband line from another provider
Internet

Line1 Line2 Line3
SRV1--------- SRV2----------SRV3
| HB1 | HB2 |
| | |
___\__________|__________/_____
| L A N |
|_____________________________|
Servers : SRV1, SRV2, SRV3
Heartbeat lines: HB1, HB2
The aim would be if any line slows down or goes down, the other remaining
server or servers will provide the internet connection automatically.
Is the diagram correct and is it possible? or do you have any suggestions or
a better way to approach this? Are there any other components aside from the
Linux kernel and Heartbeat that will be required? Is there a particular
Linux kernel that might be required to do this application?
I would certainly appreciate your inputs. I am still very relatively new to
implementing high availability on Linux. I would also really appreciate it
if you can provide steps that might be able to let me fast track my
experimentation.
Thanks for your help and best regards!
