Patent ID: 8155145

Claim:
A system for measuring performance of wireless packet communications, the system comprising: a first node; a base station that communicates with the first node; a radio network controller (RNC) in communication with the base station, the RNC comprising a trace function for capturing a copy of each layer 2 radio link control layer frame of a layer 2 frame flow from the first node; a network in communication with the RNC and a computer, the computer including a first-in-first-out-bit stream buffer having an in port and an out port: processing the layer 2 frame copies and reassembling the layer 2 frame flow into a corresponding flow of layer 3 packets, the layer 3 packets having corresponding timing information based on layer 2 frame timing provided by the RNC; detecting a number of lines containing data bytes following the logging unit header; reading each data byte from a data frame logging unit stream, discarding the contents of first n bit positions in each data frame logging unit, where n is a data header size of data frame logging unit header, and with each subsequent byte read from the frame data logging unit stream into the in port of the first-in-first-out-bit stream buffer, taking a byte away from the out port of the buffer, the byte so removed from the buffer is appended to an array representing the data frame logging unit; a performance monitor for monitoring performance of the network utilizing the layer packet flow; and a second node in communication with the network.
