Classification: H04L

Abstract:
A response time measuring system for determining time delays within a network, comprising:a first probe coupled to a first point of a network, said first probe responsive to a detection of a first signal by said first probe and to a detection of a second signal by said first probe for identifying said first signal as a request signal and for identifying said second signal as a response signal associated with said first signal, said first probe configured to determine timing information associated with said detections of said first and second signals by said first probe;a second probe coupled to a second point of said network, said second probe responsive to a detection of said first signal by said second probe and to a detection of said second signal by said second probe for identifying said first signal as a request signal and for identifying said second signal as a response signal associated with said first signal, said second probe configured to determine timing information associated with said detections of said first and second signals by said second probe; anda system manager in communication with said first and second probes, said system manager configured to compare said timing information of said first and second probes in response to a determination that said timing information of said first probe and said timing information of said second probe are each associated with said first and second signals, said system manager further configured to automatically determine whether a data transfer problem exists between said first and second points of said network by comparing said timing information of said first and second probes.
