Hi,
Can some one guide me on how to implement the weighted round
robin, below is what i tried or any other better ways to do it
Main Requirement : Incoming socket connection has to be sent
to 3 servers in the weighted round robin fashion.
Prog:1
import std.stdio;
import std.range;
import std.range.primitives;
void main()
{
auto a = [1,2,3]; // E.g :Server Array
auto b = [1,2,3,4,5]; // E.g: Socket Array
auto r = roundRobin(a, b);
writeln(r);
}
OUTPUT : [1, 1, 2, 2, 3, 3, 4, 5]
Requirement : [1, 1, 2, 2, 3, 3,1,4,2,5]
auto r = roundRobin(a.cycle, b.cycle);
Beware though that this yields an infinite range. If you just
need one round, you can use:
import std.algorithm.comparison : max;
writeln(r.take(max(a.length, b.length)));
Hi Marc,
Thank you, I have made a small update as the Server Array is
fixed length and the Socket array would be dynamic so made the
below changes as now it is working as expected
Prog:1
import std.stdio;
import std.range;
import std.range.primitives;
import std.algorithm.comparison : max;
void main()
{
auto a = [1,2,3]; // E.g :Server Array
auto b = [1,2,3,4,5,6,7,8,9,10,11,12]; // E.g:
Socket Array
auto r = roundRobin(a.cycle, b.cycle);
writeln(r.take(max(a.length, b.length * 2)));
}
