Patent ID: 6970430

Claim:
Apparatus for measuring the efficiency of transport of modem relay packets over a packet network, comprising: a first means for connecting to a first gateway of said modem relay connection; a second means for connecting to a second gateway of said modem relay connection; a computing device, operably connected to each of said first connecting means and said second connecting means through a network, for running at least one terminal program for at least one of said gateways after a steady-state connection has been established between said first means and said second means; for providing a reference modem data stream at a known modem stream generation rate to at least one of said gateways, wherein said reference modem data stream has at least one digital file that is independent from setup and protocol files for said first and said second means; and for receiving a transported modem data stream at a modem stream reception rate from a second one of said gateways after said reference modem data stream has passed through said gateways and said packet network; and means for determining the transport efficiency of said packet network by comparison of said known modem stream generation rate of said reference modem data stream to a determined throughput rate of said received modem data stream.
