Network Operators and System Integrators
Networks need to prioritize VoIP traffic. Unfortunately, the VoIP performance of firewalls, routers and
gateways can be impacted by many factors, creating
new test challenges:
- NAT traversal for SIP and H.323 can add voice
latency.
- IPsec encryption drastically reduces voice call
throughput.
- New Denial of Service attacks severely disrupt VoIP
and VoIPv6 services.
- Data applications such as web, P2P and email can
seriously degrade VoIP quality of service.
- IPv6 dual-stack operation adds complexity that can
sap device call set-up rates.
Agilent’s new VoIP test software for NetworkTester
enables you to measure VoIP performance and ensure
that your network equipment will scale to meet QoS
requirements.
