Hi LVS-users,

I'm looking for a load balancer solution, which does true load balancing 
instead of load sharing, like describe in [1].

I found Jeremy Kerr's excellent feedbackd [2]. But it seems it does not 
provide all functions I need:

* no options for persistent connections

* have more then one VIP on the same TCP Port
* have real servers that are mixed members of a VIP: i.e.
TCP 192.168.100.40:80 wrr
-> 10.254.0.110:80 Route 100 0 0 
-> 10.254.0.120:80 Route 100 0 0 
TCP 192.168.100.41:80 wrr
-> 10.254.0.110:80 Route 100 0 0 
-> 10.254.0.120:80 Route 100 0 0 
-> 10.254.0.130:80 Route 100 0 0 

*) implement a configurable fallback schedule (wlc/sed) when all servers are 
busy (weight = 1)

*) Do TCP-Checks on RIPs/Port

Please tell me if there are any other implementations of [1] out there. The 
mentioned phiranha seems dead.

TIA Sascha.
