WAN Analytics

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

End-End User App Experience

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. Flow data from routers is analyzed and automatically identified to applications. Various WAN attributes such as which interfaces(s) or service provider(s) a particular application is traversing are tracked. This enables enterprise to determine when poor user experience is caused by WAN issues versus being caused a campus issue such as poor wireless.

Per Minute WAN Analysis

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. The system correlates WAN traffic every minute with particular applications and users, focusing on the “high link utilization minutes”. This helps answer questions such as which users and applications are the culprits in causing traffic bursts, or how much are non-essential applications costing.

Cloudsourced App ID

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. Unlike any other analytics system available, voyance is able to leverage this dynamic database to perform automatic application identification based on much simpler markers, such as destination IP address only, which is the only marker available in many non-SPAN port, plain vanilla Netflow-only, Voyance deployments.
