Quality of Experience issue

Verify the topology to determine which device is at the far end of the HP Velocity protected flow.

‡HP Velocity helps when there is network loss.

‡Check the HP thin client

and server system resources (CPU, RAM, etc).

‡The quality issue could be due to low bandwidth on the link, or high latency.

The application may require an even higher network quality.
