IP Core Monitoring Probe


The VB20 IP core monitoring probe is a critical component of the VideoBRIDGE monitoring system and is useful for monitoring digital video that is carried across an IP infrastructure. This portable network service tool is ideal for pure IPTV networks and OTT delivery networks.

The ability to simultaneously monitor 260 IPTV services makes the VB20 probe an incredibly powerful tool for any network engineer. With optional add-on licenses, the VB20 can monitor OTT/ABR streams at master play-out or at the CDN origin server in all common streaming formats including Microsoft Smoothstream™, Apple HLS™, Adobe HDS™, MPEG-DASH and basic RTMP.  

The monitoring of critical parameters such as loss distance measurements and detailed jitter values will give operators invaluable and precise feedback of network performance. With the patented MEDIAWINDOW™ historical data can be easily accessed for meaningful visualization of media flow in IP networks. 

The power of confidence monitoring is further enhanced by continuous monitoring and alarming for vital parameters like bandwidth overflow/underflow, RTP errors and signal loss. Based on a highly sophisticated threshold template system alarm granularity can be set to reflect actual status with irrelevant alarms being effectively masked. The VB220 can also be expanded with ETR 101-290 capabilities for full transport stream fault detection. Finally, the unique FSM™ framework also allows checking and continuous monitoring of middleware and network services vital to customer QoE.

Each VB20 runs an HTTP server with the client as a web browser, so no need to install custom software on computers needing access to the measurement data.  Users can pull results directly from the probe itself or connect via the VideoBRIDGE Controller server for advanced alarm correlation and filtering. SNMP traps and the Eii (External Integration Interface) XML API allow the probe to be easily integrated into any NMS or 3rd party system.
