IP Core Monitoring Blade


The VB220-DMG blade is similar to the flagship VB220 controller blade for all applications in any network where digital video is carried across an IP infrastructure. Built with a form factor for deployment in Sencore´s Digital Media Gateway chassis, the VB220-DMG has the unique capability of reducing the infrastructure needs and costs in situations where the customer is deploying or has already deployed the Sencore DMG platform.

The VB220-DMG fully has the same IP monitoring capabilities as the standard VB220 and thus it can be a critical tool for monitoring digital video that is carried across an IP infrastructure. This network service device is ideal for pure IPTV networks, OTT delivery networks, and hybrid RF networks with IP transport cores (such as digital cable and terrestrial networks).

The ability to simultaneously monitor 260 IPTV services makes the VB220-DMG blade an incredibly powerful tool for any network engineer. With optional add-on licenses, the VB220-DMG 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 VB220-DMG 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 blade 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 blade to be easily integrated into any NMS or 3rd party system.
