1. A method for analyzing packetized network traffic comprising the steps of:
a. receiving a copy of said network traffic comprising one or more streams;
b. filtering said received network traffic to isolate each stream from said one or more streams;
c. forwarding packetized data corresponding to each stream to a native streaming interface, said native streaming interface
providing minimum time distortion as compared to said network traffic to permit media stream analysis and monitoring to indicate
said network's influence on each isolated stream and measure each isolated stream's conformance to a pre-determined stream
standard;
d. computing statistics associated with each isolated stream, said statistics comprising at least a delay factor (DF) parameter
defining an instantaneous flow rate balance representing a virtual buffer delay that is needed to prevent data loss and absorb
network jitter growth; and
e. forwarding, for each isolated stream, said computed statistics to a data consumer.
