There’s good news out there for those interested in utilizing Voice over Long Term Evolution, or VoLTE, services over virtualized network infrastructures. CENX, a global leader of service orchestration solutions for software-defined networks, has announced that together with Spirent -- a global leader in test and measurement -- it has successfully demonstrated that it works.
According to a joint statement from the companies, with CENX (News - Alert)'s Cortx Service Orchestrator, “Service providers have a single pane of glass for visualization of their service topology, network utilization and performance metrics, so they can assure a high quality of service. Spirent Landslide enables end-to-end testing of the mobile network, including sophisticated voice Perceptual Objective Listening Quality Assessment (POLQA) measurements.”
With VoLTE deployments still in their infancy (only 14 operators in seven countries worldwide have launched commercial service), service providers are leveraging Network Functions Virtualization (NFV) technology to build out their VoLTE infrastructure most cost-effectively.
"This demonstration proves that, with the right tools in hand, management of complex network transformations doesn't itself have to be complex," said Chris Purdy, CTO of CENX. "Cortx Service Orchestrator is able to provide a unified view of the mobile network from an end-to-end VoLTE services perspective, across both physical and virtual elements. This is a landmark first in the industry."
According to the two companies, Spirent (News - Alert) Landslide provides the comprehensive Mobile Packet Core (MPC) network test environment, emulating real-world control and data traffic load through a virtualized Evolved Packet Core (vEPC), and calculating response times, throughput and real-time POLQA voice quality measurements. “Cortx Service Orchestrator ingests these metrics, and performs big data correlation and analytics,” they said. “Using intuitive search capabilities, operations personnel can quickly access the relevant data, analyze the voice quality performance in the context of the service topology, and drill down into details as needed.”
CENX and Spirent will discuss their findings at the Mobile World Congress (News - Alert) in Barcelona, Spain, March 2nd through the 5th.
