Abstract:
1. A method for determining performance in a network, the method comprising: transmitting a signal from a transmitter onto a first portion of the network; receiving the signal at a receiver, wherein receiving the signal at the receiver includes receiving the signal with first errors caused in the first portion of the network; returning the signal to the transmitter, wherein returning the signal to the transmitter includes returning the signals with second errors caused in a second portion of the network; correcting errors introduced into the signal from the receiver to the transmitter at the transmitter, correcting the second errors to leave the first errors in the signal; and determining the performance of the first portion of the network from the transmitter to the receiver by comparing the signal with the first errors with the signal transmitted at the transmitter to determine the performance of the first portion of the network.
