hmm, I think of an LVS connection for tcp being the series of packets
starting with SYN and ending with FIN. If the director gets a new
SYN from the same client, the director will schedule a new connection
and pick the next realserver.

I don't know how this could be the same for udp. I remember someone
using LVS on ntp, where the client was connected to the same realserver
for a period of time before being rotated to another realserver. 
So I thought a timeout was used with udp
