Abstract:
1. A method for one or more hardware modules of a network diagnostic component that is placed in-line between first and second nodes in a network to compare in real time the duration of a portion of a speed negotiation signal with a desired duration, the method comprising: an act of receiving a speed negotiation signal from the first node for communication with the second node during a speed negotiation window, wherein the speed negotiation signal includes a first component comprising one or more data units and a second component comprising one or more common voltage units; an act of detecting the one or more data units of the first component and the one or more common mode voltage units of the second component; an act of generating aligned data representing the detected one or more data units of the first component and the detected one or more common mode voltage units of the second component, while routing the speed negotiation signal to the second node, the aligned data being such that the one or more data units can be measured without also having to measure the one or more common mode voltage units and the one or more common mode voltage units can be measured without also having to measure the one or more data units; an act of measuring the duration of the one or more data units of the generated aligned data; an act of comparing the measured duration of the one or more data units with a desired duration; and an act of generating a record that specifies whether the measured duration of the one or more data units compare with the desired duration.
