Window scaling

[pouchie1]

Hello,

I would like to understand how I can interpret the window scale option in wireshark. I got the window size of 65535. Then I got the window scale :2 ( multiply by 4 ).

How can I read this? I think I should read like this it would be 65535 X 2^2 ( 2 to the power of 2 ). power of 2 comes from the window scale value. But, I am not sure what "multiply by 4 " means? Am I right in my reading and also what "multiply by 4 means?

Thanks
