ABSTRACT:
A system for determining network characteristics includes a processor including a packet generation component and a packet evaluation component. The packet generation component generates send test packets for communication into the network. The packet evaluation component is responsive to receive test packets for determining network speed and utilization; upon detecting that the network streaming utilization is not significantly high, evaluates the test packet sequences for a first discard pattern representing actual discard red rate; and upon detecting that the network streaming utilization is significantly high, evaluates the test packet sequences for a second discard pattern representing effective discard yellow rate and effective non-discard green rate.
