In October 2006, Nortel put its Secure
Routers 1004 and 3120 to the test to
prove that these offerings deliver supe-
rior performance and Voice over IP
(VoIP) quality of service, regardless of
the level of traffic on the network or the
IP services enabled.

Nortel conducted a series of tests using
an Ixia Traffic Generator running Chariot
— the industry’s leading test tool for
emulating real-world applications to
predict device and system performance
under realistic load conditions.

Results showed, unequivocally, that the
Secure Routers effectively transport and
prioritize VoIP traffic in congested and
oversubscribed network environments,
and deliver business-quality voice to
users. These results, measured by Mean
Opinion Scores (MOS), were consis-
tently high in all test scenarios, even
when traffic loads were increased and
complex IP services such as Access
Control Lists (ACL) and firewalls were
added to the test mix.

Note: The MOS or Mean Opinion
Score is a measurement of the quality of
human speech at the destination end of
the circuit. MOS is expressed as a single
number in the range of 1.0 (lowest
perceived quality) to 5.0 (highest
perceived quality). Scores over 4.0 indi-
cate “toll-quality”.
