Hello LVS list,

I have installed and configured a Piranha cluster (which is an
LVS subcase) of three real servers and a director, under
Redhat Linux 7.3.

For the clients, I am using a wireless network. I have a laptop
PC connected to the Piranha network via a wireless network.
I have a VMware virtual machine installed within the laptop PC
client. Thus, I have two clients. I am using http and ftp requests.

That's all fine. What I would like to do, is in fact the following :

I would like to change the scheduling algorithm (until now I am
using rr scheduling) used in Piranha to take into account the
network state. Indeed, we would like to implement a new
scheduling algorithm that will include a monitoring tool. This
later  will give informations about the state of the network, and
then decisions about the scheduling process will be done.

My question is : where exactly I have to make changes; i.e.,
in which files ?. Namely, I have to see the source code of
Piranha scheduling algorithms, and I have to see where to
include the monitoring tool.

I did't find any documentation about the internal design
of Piranha.

Many thanks in advance for any help (hint).

Mustapha
