Ixia Launches VoIP Testing OfferingMar 18, 2008 (Close-Up Media via COMTEX) -- Ixia, a supplier of IP test systems, announced the latest release in its residential and business VoIP testing. IxLoad Voice matches the capacity of modern media gateways with a 1 million SIP- and RTP-based endpoints per chassis. Ixia reports that Infonetics Research forecasts a 25 percent compound aggregate growth in residential and SOHO hosted VoIP subscribers through 2011, when they are expected to number over 187 million. To meet this growing demand, network equipment manufacturers must deliver VoIP devices that can handle more calls and a complex array of protocols and services. Both network equipment manufacturers and converged service providers of all sizes need to verify the performance and interoperability of new VoIP devices and networks, ensuring that they can handle complex, heavy VoIP traffic loads. IxLoad tests VoIP network components, including IP-based PBXs, softswitches, call managers, session border controllers, and media gateways, using scenarios involving multiple voice protocols, 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 predict live-network capacity - 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. IxLoad delivers real-time evaluation of end-user quality of experience (QoE), such as PESQ scores for 300 simultaneous calls - making it unnecessary to wait for time-consuming, post-test analysis. Ixia is a supplier of test, measurement and service verification solutions to Internet equipment manufacturers, carriers, service providers, government agencies and enterprises.
