github.com/smallnest/weighted (go): Package weighted implements two weighted round robin algorithms. One is the smooth weighted round-robin balancing algorithm used in Nginx, and you can use "w := new SW{}" to use it. The other is wrr used in LVS and you can use "w := new RRW{}" to use it.  For Nginx smooth weighted round-robin balancing algorithm, you can check https://github.com/phusion/nginx/commit/27e94984486058d73157038f7950a0a36ecc6e35.
