SCENARIO
VoIP is a major component of service providers’ consumer and business offerings. Modern deployments now call for millions of simultaneous VoIP endpoints.
Although VoIP connections have a low bandwidth requirement, they are very sensitive to latency and jitter. Care must be taken to enforce appropriate QoS policies for voice traffic, balanced with the QoS requirements associated with video and data services.
IXIA SOLUTIONS
The IxANVL Session Initiation Protocol (SIP) suite tests the conformance of devices to SIP.
Ixia supports video and data protocols, in addition to VoIP—making it perfect for testing a wide variety of components, including:
