Re?? Re?? [DISCUSS]Load balancing weight

Hi,


I got your point. And from the point of the code logic and the functions that 
can be used after code implementation, I agree that the weighted polling 
algorithm is indeed applicable to scenarios without setting weights.


But in terms of module division and architecture design, the weight will be 
coupled into the existing simple round robin algorithm. In fact, the weighted 
round robin&nbsp;algorithm is also a separate algorithm, which is different 
from the simple&nbsp;round robin&nbsp;algorithm in terms of design[1].


What I want to express in my last email[2] is that from the perspective of 
module division and enhancement of module clarity, Is it better 
to&nbsp;introduce weighted rotation training and other algorithms into new 
algorithms instead of adding weight logic to the previous algorithms?

Hi, I think you have misunderstood. In fact, the weighted smooth polling 
algorithm is also suitable for scenarios where no weight is set.

&gt; I got your point.
&gt; 
&gt; 
&gt; I agree with your about the all algorithms you mentioned should be 
measured by weight. But I think we should keep the original algorithm which is 
not based on weight selection. and the algorithm based on weight should appear 
in a new algorithm.
&gt; 
&gt; 
&gt; In my opinion. Actually in our production environment, there are few 
differences in the performance of the machines as you mentioned. In most cases, 
the machine performance and configuration are consistent in our production 
environment.
&gt; 
&gt; 
&gt; So there are two scenarios for this weight based algorithm. The first one 
is the one you mentioned. The second may occur when a user wants to use half of 
the performance of machine A, rather than full use of machine A.
&gt; 
&gt; 
&gt; So is it better to keep the original algorithm and also provide those new 
selection algorithms based on weight?
&gt; 
&gt;

&gt; 
&gt; 
&gt; Let me give an example. It might be better. Suppose my computer A has twice
&gt; the processing power of computer B. Then I have three tasks. According to
&gt; the polling algorithm, A will handle two and B will handle one. Isn't our
&gt; purpose of load balancing to make each machine work evenly?

&gt; &gt; &gt; Hi, everyone. I??m currently designing weight-based load 
balancing. My&gt;
&gt; &gt; &gt; point of view is that all load balancing needs to be done based 
on
&gt; weights,&gt;
&gt; &gt; &gt; because load actually means that machines with good performance 
are&gt;
&gt; &gt; &gt; expected to handle more tasks. Therefore, weights should be 
Reflected
&gt; in&gt;
&gt; &gt; &gt; each load balancing algorithm, it should be a default attribute 
in
&gt; load&gt;
&gt; &gt; &gt; balancing.&gt;
&gt; &gt; &gt;&gt;
&gt; &gt; &gt; Hope to get your suggestions.&gt;
&gt; &gt; &gt;&gt;
&gt; &gt; &gt;&gt;
&gt; &gt; &gt; Best&nbsp; wishes??&gt;
