ContexView is a performance analytics and anomaly detection solution that provides service providers with visibility to network performance, potential issues and subscriber usage patterns. ContexView aggregates data generated by ContexNet to provide reports on both ContexNet and the operator network, allowing the operator to, for example, view the impact of configuration changes or new feature introduction. ContexView alerts the operator of conditions that may be an indication of subscriber service impact, allowing proactive corrections of the underlying issue before the end-user contacts support.
ContexView enables extensive performance monitoring (as shown in the graphs above) of both ContexNet and the mobile network, highlighting unexpected changes in network performance or functionality, showing the effect of configuration changes on the performance and viewing the impact of network equipment changes. It eases troubleshooting, allowing the operator to isolate performance issues to device type, locate areas of network congestion, identify problematic end user devices, file types etc., analyze Media Optimization and Analytics issues or view CPU, memory and disk utilization trends.
ContexView collects data from ContexNet logs and IPFIX records and stores them in a database, which is used by the reporting system. It also provides an option of a central server that collects data from all the operator sites, allowing for a centralized view of the entire operator network.
It also consists of a TCP Anomaly Detection tool, which detects and alerts the network operator of possible TCP related issues that may be caused by the ContexNet TCP Bridge. The TCP Anomaly Detector analyzes these IPFIX records generated by ContexNet and identifies endpoints that continuously exhibit certain TCP behavior that can be an indication of an issue with the TCP Bridge. For each such endpoint, the TCP Anomaly Detector records and displays the IP address and port number, issues traps and can email the operator.
