[pox-dev] pox-dev Digest, Vol 25, Issue 17

[shads s]

Hey all

Is it possible to configure the servers in the ip_loadbalancer?
For example, suppose I have 2 servers wherein server 1 has a larger
capacity than server 2 and hence can handle increased traffic coming from
the clients compared to server 2.
I need to make this functionality work. Can anyone guide me?
