loxilb currently supports RR, WRR distribution but in many cases LC (least connections) become necessary.

The initial support is added. To configure using loxicmd - 

loxicmd create 20.20.20.1 --tcp=2020:8080 --endpoints=31.31.31.1:1,32.32.32.1:1,33.33.33.1:1 --select lc

apiVersion: v1

  name: sctp-lb
  annotations:
    loxilb.io/lbmode: "fullnat"
    loxilb.io/epselect : "lc"
