Unable to simulate optimization values

Dears

Can anyone help us simulate the values with the reports created by WAAS

We received the following values from our provider, for a site they see

83.82Gig received and 99.49Gig send, so total of 183.31gig over the line

when we make a monthly report for the month january

System Traffic Summary (Jan/01/10 00:00:00 - Jan/31/10 00:00:00)(GMT)

Device	Original Traffic (Excludes Pass-Through)	Optimized Traffic (Excludes Pass-Through)	Pass-Through Traffic	Reduction (%) Excluding Pass-Through	Effective Capacity Excluding Pass-Through	Reduction (%) Including Pass-Through	Effective Capacity Including Pass-Through

Device0001

561.836 GB

276.742 GB

30.745 GB

50.74

2.03 X

48.11

1.92 X

Both provider router and WAAS are connected to a L3 switch so the provider router doesn't do the internal routing

Looking at the report from WAAS he has a total of 306Gig on traffic (optimized traffic + pass-through)

but the provider only has a total of 183Gig

What can explain the difference in values?

Thanks for any help

Hi Bart,

The calculations for the various reports is located here:

If you have any additional questions, please let us know.

Hi Zach

thank you for the reply

but the issue we have is that the values displayed by WAAS don't match with the edge router values

for some sites the WAAS has processed more traffic then that passed the router or the other way, which makes it difficult to interprete the percentage values

For internal routing it normally doesn't optimize traffic, internal routing is processed by an internal L3 switch and not by the edge router with WCCP

maybe good to know we have version 4.1.5b, i heared that reporting has improved in 4.2
