Ixia gets sophisticated with VoIP testing
With VoIP becoming ever-more popular and common, Ixia has amped up the performance of its VoIP tester with a new module that can handle higher line capacities. The company’s IxLoad Voice now has a capacity of 1 million SIP- and RTP-based endpoints per chassis.
Ixia’s new Acceleron-XP load module implements voice protocols with hardware to reach these capacities.
IxLoad tests VoIP network components, including IP-based PBXs, softswitches, call managers, session border controllers and media gateways, using highly realistic scenarios involving multiple voice protocols, complex calling sequences, and triple-play mixes of voice, video and data traffic.
IxLoad’s subscriber modeling emulates user communities that vary in service usage and timing. This approach yields performance results that accurately predict live-network capacity, Ixia said, allowing service providers to correctly provision their networks.
Ixia supports all of the essential VoIP signaling and transmission protocols, including SIP, RTP, SCCP, MGCP, H.323 and H.248 – with complex call flows and Class 5 features.
“VoIP protocols and technology may be well understood, but there are a host of potential problems when a high number of calls are mixed with large volumes of data and video traffic,” said Anupam Sahai, vice president of marketing at Ixia. “We developed our Acceleron-XP, VQM modules and IxLoad test application to emulate city-scale communities of real-world users – allowing our customers to discover and solve their device and network problems before their customers do.”
