To calculate bus usage and bit rate errors,
Step 1
Enter the range of packets to be examined in the text boxes marked
"From packet" and "To packet."
Step 2
Click the "Calculate" button.
At this point, bus usage will be calculated.
Global:
Time Usage - sum of percentage used by all packets/ordered sets _on both
directions of the link_. Can be 0-200%
Bandwidth - all the bits for all packets/ordered sets _on both directions of
the link_ divided by the time for the range. Can be from 0-5000
MBits/second
Link Packets:
Time Usage - percentage used by all link packets on both directions of the
link separately. Can be 0-100%
Bandwidth - all the bits for all link packets on both directions of the
link divided by the time for the range, separately. Can be from 0-2500
MBits/second.
Data Packets:
Time Usage - percentage used by all Data packets on both directions of the
link separately. Can be 0-100%
Bandwidth - all the bits for all Data packets on both directions of the
link divided by the time for the range, separately. Can be from 0-2500
MBits/second
Destination QP:
Time Usage - percentage used by all packets directed to the specified QP on
both directions of the link. Can be 0-200%. Displayed for total packet usage
and usage just by the payload data
Bandwidth - all the bits for all packets directed to the specified QP on both
directions of the link divided by the time for the range. Can be from 0-5000
MBits/second. Displayed for total packet BW and BW just for the payload
data.
