	Not very correct. Description from net/netfilter/ipvs/Kconfig
should be more useful:

<SNIP>
The weighted failover scheduling algorithm directs network
connections to the server with the highest weight that is
currently available.
</SNIP>

	I.e. something like "bigest available server that is not 
overloaded".
