Enhanced Network Visibility

NVRT automatically discovers the network and assets in real-time. NVRT details everything you need to know about the network, including each device’s network profile, PTP lock state, and connectivity status. Live auto-generated mapping makes it easy to understand the network architecture and dependencies. Avoid disruption by detecting changes in real-time plus receive notifications regarding intrusions and other network events.

Normalized Network Dashboard

NVRT leverages the power of network telemetry to produce modern easy-to-use dashboards to describe all of the essential details about every network device used. Simple and intuitive dashboards turn non-IT people into experts, displaying information that is needed in a clear and concise way. Diagnose issues faster and prevent lengthy downtime regardless of switch manufacturer.

Real-time Network Performance

NVRT improves network performance and increases availability by identifying anomalies on a port-by-port basis. NVRT provides real-time updates on transmit and receive bandwidth and aggregate data errors including: CRC errors, dropped & discarded packets, and collisions. NVRT enables the labeling of multicasts using static assignments or via integration with system orchestration software. 

PTP System Monitoring

NVRT monitors the health of the PTP system to look for issues that can turn catastrophic for a media system. NVRT identifies the PTP clock tree, including the masters and boundary clocks and their relationship. NVRT also records PTP information including an offset from the master, mean path delay, and skew values, and provides alarms to warn of deviations from the norm.

Real-time Inventory Management

NVRT catalogs every asset discovered on the network making it possible to track down every detail about a system’s inventory. Built-in Elasticsearch makes it quick and easy to locate hardware and software on the network using any of the product’s attributes, including IP address, MAC address, hostname, manufacturer, and more. Add labels and groups to devices to make identifying device location and functional category easier.

Enhanced Network Security

NVRT provides detailed device network profiling and risk assessment making it simple to identify security gaps. First-of-its-kind network profile targeting makes it possible to detect changes in device configuration. Coupled with NVRT’s real-time network intrusion detection, NVRT enhances your overall network cybersecurity.
