(7) QoS Features. The UCR 2008, Change 2, Section 5.3.1.3.6 states that
Access products shall be capable of providing a minimum of four queues, assign any
“tagged” session to any of the queues, and support Differentiated Services per hop
behaviors and traffic conditioning with an assigned bandwidth percentage per queue,
and meet traffic conditioning requirements. The QoS, which includes rate-shaping,
performed as configured. All variance was within the limitation of resolution of the test
instruments.
(8) Network Monitoring. Network Monitoring via Simple Network
Management Protocol (SNMP) was evaluated by the DISA-led IA team and published
in a separate report, Reference (e).
(9) Security. Security testing is accomplished via DISA-led IA test teams
and published in a separate report, Reference (e).
b. End-to-End (E2E) Performance Requirements. Voice, Video and Data
Services. These requirements were verified and met using simulated voice, video,
and data traffic in an operational emulated environment. To meet E2E requirements
the SUT must be deployed in accordance with deployment guide and engineering
guidelines provided in UCR 2008, Change 2, paragraph 5.3.1.4. E2E performance
was evaluated in a homogeneous and heterogeneous configuration as depicted in
Figures 2-3 through 2-5.
1. Voice Services.
a. Latency. The UCR 2008, Change 2, paragraph 5.3.1.4.1.1 states
that latency shall not be more than 6 ms E2E across the ASLAN as measured under
congested conditions. The SUT was tested at .132 ms which met this requirement.
b. Jitter. The UCR 2008, Change 2, paragraph 5.3.1.4.1.2 states that
when transporting voice IP packets E2E jitter shall not be more than 3 ms over any 5-
minute measured period of congested conditions. The SUT was tested at .005 ms
which met this requirement.
c. Packet Loss. The UCR 2008, Change 2, paragraph 5.3.1.4.1.3 states
that actual measured packet loss across the LAN shall not exceed 0.045 percent
within the defined queuing parameters. The packet loss requirement shall be
achievable over any 5-minute measured period under congested conditions. The SUT
was tested at 0 percent which met this requirement.
2. Video Services.
a. Latency. The UCR 2008, Change 2, paragraph 5.3.1.4.2.1 states
that latency shall not be more than 30 ms E2E across the ASLAN as measured under
congested conditions. The SUT was tested at .107 ms which met this requirement.
