Industry Standard Network Model (TIA-921/ITU G.1050)
A separate option, the TIA model-based network emulation (TIA Test Suite option) is available that
provides a standards-based test platform for testing voice, data and video devices and applications that operate
across an IP network such as the Internet or an enterprise wide area network. This option implements the
TIA-921 Network Model for Evaluation of Multimedia Transmission Performance Over Internet Protocol as defined
by the Telecommunication Industry Association. The industry standard model represents an end to end network
configuration consisting of network segments that include the local and remote LANs, the local and remote Access
links and the Core IP network.
The TIA Test Suite defines 1064 scenarios derived from variations of network
configurations and impairment levels. These combinations provide a diverse range of test cases representative of
existing IP networks that products may encounter and be expected to operate within.
This system enables developers and service providers to evaluate the performance of IP services such as VoIP, Video over IP, Web Services and other emerging applications.
