In linux kernel since version 4.1 (release Date: 2015-06-21)  
The weighted overflow scheduling algorithm directs network
connections to the server with the highest weight that is
currently available and overflows to the next when active
connections exceed the node's weight.

If you want to compile it in kernel, say Y. To compile it as a
module, choose M here. If unsure, say N.
