IP Core Monitoring Blade
The VB220 IP-PROBE is a monitoring platform for all applications in any network where digital video is carried across an IP infrastructure. This network service tool is ideal for both pure IPTV networks and hybrid networks with IP transport cores (such as digital cable and terrestrial networks).
The ability to monitor continuously 260 services makes the VB220 blade just as powerful as its portable version, the VB20. 3 x VB220 blades can be placed in one 19" 1RU chassis, giving a total of 780 streams monitored in a small form factor. This is an invaluable tool for any network engineer attempting multicast detection on multiple VLANs or in the process of IGMP tracking.
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 MediaWindowTM 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 threshold template system alarm granularity can be set to reflect actual status, irrelevant alarms being effectively masked. The unique FSMTM framework also allows checking and continuous monitoring of middleware and network services vital to customer QoE.
The VB220 may be used with optional demodulator interfaces, resulting in a very compact monitoring solution particularly suited for systems that use IP distribution to regional nodes. The VB220 monitors IP, ASI and optional demodulator inputs simultaneously, and the transport stream and service compare mechanism makes it easy to validate correct local insertion at regional head-ends.
SNMP trapping and XML export enable the IP-Probes to be implemented in any NMS system with alarm generation; either directly from the probes themselves, or via the VBC server for advanced alarm correlation and filtering. Each VB220 contains the Eii (External Integration Interface) API for seamless and easy integration into any 3rd party system.
Each IP-Probe 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. Modern web 2.0 techniques such as AJAX are used to facilitate advanced interface behavior in a standard web browser without the need for any plug-ins.
