Detailed insights into link performance with cross-stack data analysis.
Voyance analyzes and provides insight into all aspects of the client user experience. An essential element of this the user experience is across the wide area network links. Over a traditional Enterprise WAN topology interconnecting branches by way of private links and data centers, WAN analytics helps answer the question of how user experience is affected by different WAN interfaces, service providers, overlays, etc. It also addresses questions about how exactly user and application traffic, especially non-essential applications, can contribute to short periods of high link utilizations and what to do about it
Detailed, real time application performance metrics are collected by crawlers performing DPI on live packets, from application servers directly via SYSLOG or API, as well as from client devices running the Voyance Client.
Instead of simply aggregating WAN analysis breakdowns over time and presenting them in charts, minute by minute analysis and correlation of WAN traffic is performed to determine when high levels of link utilization occurs and what is causing the issue.
By leveraging the cloud and a multitude of customer environments, the system is uniquely able to dynamically learn and fingerprint applications based on various markers such as DPI-based signature matching, certificate matching, watching DNS queries, etc.
