Network diagnostic systems and methods for transmitting and receiving network messages

A networking system is provided. The networking system may include a network diagnostic component. The network diagnostic component may perform any of a variety of network diagnostic functions. The network diagnostic component may include a diagnostic module. The network diagnostic component may also include at least one transceiver. The transceiver may receive a signal from a first node. The signal may form one or more network messages, for example. The transceiver may send the signal to a second node. The transceiver may send the signal to the diagnostic module, which may alter the signal. For example, the diagnostic module may digitally retime the signal, may alter the content of the messages themselves, and/or may alter the signal in other suitable ways. The transceiver may send the altered signal to the second node.
