Abstract:
An indexing system for generating graphical representations of large volumes of trace data captured from a computer network comprising:a protocol analyzer operably connected to the computer network and having a trace memory in which trace data comprising data entries representing selected portions of actual data communications from the computer network is stored; means for generating an index of a selected granularity percentage of the trace data in the trace memory by reading the selected granularity percentage of the trace data in the trace memory and creating a map to individual data entries in the selected granularity percentage of the trace data that includes at least a representation of where each of those data entries is stored in the trace memory; and a host processor operably connected to the protocol analyzer and the means for generating the index and having a computer display device and software executing on the host processor that generates at least two graphic representations on the computer display device of the trace data in response to and based on the index, including a first graphic representation generated by setting the selected granularity percentage at a first percentage and a second graphic representation similar to the first graphic representation generated while the first graphic representation is being displayed by setting the selected percentage at a second percentage that is greater than the fist percentage to regenerate the index, such that the first graphic representation is generated in near real time and the second graphic representation is generated at a later time and improves the granularity of the second graphic representation as compared to the first graphic representation.
