We use a several connections to the financial providers. This connections are low bandwidth (up to 2 Mbps). This connections used by a number of front end services from a nubmer of departments and we could not differentiate its and configure QoS. But from time to time some one produce an extremely high traffic spikes (less than 30 seconds) without congestion avoidance mechanisms. Our task - is to find such applications and report to management and developers a problem. Also if we'll be aware about it we could configure QoS.
