V-NID™ Performance Platform LTE, Small Cell Backhaul & VoLTE Performance Assurance Accedian Networks’ V-NID™ Performance Platform helps mobile operators deliver flawless backhaul network QoS by using a unique combination of virtualized instrumentation, standards-based+ real-time metrics, powerful reporting and troubleshooting tools.

Using existing network elements (NEs) as test endpoints, the V-NID platform performs high-precision one-way measurements at layers 2, 3 and 4 without requiring clock synchronization. Where NEs lack integrated performance monitoring (PM) support, Accedian pluggable performance modules, elements and software agents provide additional test points to eliminate blind-spots.

Active per-flow monitoring uses standards-based Ethernet SOAM, Layer 3 TWAMP and ICMP/UDP Echo protocols to ensure interoperability in multi-vendor networks. Detailed statistics and Quality of Experience (QoE) KPIs including VoLTE MOS and R-factor (ITU-T G.107 E-Model) are calculated in real-time, with sub-second granularity.

The result is a complete, current view of backhaul network performance: the Network State+. Maintained in a database with an XML North Bound Interface (NBI), hundreds of QoS metrics can be accessed by 3rd-party platforms, bringing performance-awareness to network management systems, SDN controllers, and more.

The V-NID platform is easy to setup and scale, with centralized provisioning, management and reporting unifying network-wide service assurance. Programmable alarm filtering, graphing, reporting and performance analysis tools in the V-NID Analyzer web-app provide proactive end-to-end and per-segment visibility.

As operators roll out VoLTE, small cells, LTE-Advanced and other performance-critical architectures and apps, QoS issues can quickly degrade, interrupt or prevent calls and data from reliably reaching subscribers.

In a world where “5-bars” performance is expected anytime, anywhere, anything less impacts customer loyalty and revenue. VoLTE MOS & R-Value, Latency, delay variation, availability, and packet loss are just a few key metrics that must meet demanding specs for successful service delivery.

A real-time view of network performance, lets operators respond quickly to QoS threats - and offer the best possible experience to their customers.
