Ashwin Karpe commented on CAMEL-5039:
-------------------------------------
Hi Xavier,
Your analysis is entirely correct. My original implementation was weight-biased
and the proposed one is skewed towards randomness.
More importantly, upon closer review, your algorithm offers the right balance
between weighting and randomness. In addition, the solution offers better
ability to test that the weighting criteria is being met periodically.
I will review your code and apply it to the trunk.
Thanks for your input. I appreciate it.
Cheers,
Ashwin...
Thank you for your thought and comments.

> As Mark Harwood explained in last comment of CAMEL-3197 the
> WeightedRandomLoadBalancer is not doing a good load balancing job if some
> weight are a lot bigger than some other weight.
> See in the attached example (current-impl-result.txt), the first and third
> routes are always called at the very beginning of every 50 iterations
> loadbalancing round.
> I propose a modified algorithm that do a more balanced loadbalancing
> (new-impl-result.txt)
> Attached the test program with the proposed implementation.
