How to compute Web Dispatcher's Load Balancing

[Former Member]

Hi Experts,

I have to decide the type of Load Balancing.

Sizing Guide suggests as follows,

but I can't understand how to comupute SAP System.

Could you tell me about them?

<Type>

  1.Client IP address-based

  2.Static round robin

  3.Weighted round robin

  4.Dynamic load balancing

Especially, I'd like to know about

"3.Weighted round robin" &

"4.Dynamic load balancing"

(interval, what factor decide system load)

And if it uses or can use the data/value of message server,

please tell me it.

Thank you for advance.

Best Regards,

Toshikazu

Hi Tobias,

Thank you for your reply.

I've already checked helpportal.

I know It describes about the way to load balancing,

but it doesn't describes how to compute.

If you know it, please let me know.

Best Regards,

Toshikazu

Weighted round robin takes into account the quality (responsiveness) of the servers, the ones having better quality will be preferred. Basic round robin means system1, system2, ... systemX, system1, ...
