Advanced network analytics for a mobile-first campus

Figure 1: Aruba NetInsight Topology

Product overview

Aruba NetInsight delivers actionable insights into network performance for improving the quality of your user's mobile experience, via continuous monitoring, analysis and benchmarking. Using powerful machine learning algorithms and Aruba's extensive wireless know-how, NetInsight arms IT organizations with the intelligence needed to proactively optimize how data, voice, and video applications perform, across your entire campus - local and remote locations. 

As organizations move to mobile environments with unpredictable connectivity patterns, more wireless initiated voice and video usage, and access from multiple device types due to BYOD programs, NetInsight delivers the visibility and learning needed for today's always-on network requirements.

Key Features

• Network analytics as-a-service
• Transforms existing network data into powerful insights
• RF configuration based on environmental classification
• Anonymized peer-to-peer benchmarking
• Recommendations for continuously improving network performance and user experience

How NetInsight Works

Data feeds from multiple sources including Aruba wireless infrastructure, DHCP and authentication servers are gathered via a data collector that is deployed onsite in your datacenter.

The data is then compressed and sent via a secure tunnel to NetInsight cloud instance.

Leveraging latest cloud technologies, machine learning based models and Aruba's Wi-Fi expertise, NetInsight analyzes connectivity and performance issues in the network.

A cloud-based dashboard allows network admins to view insights along with root causes, and more importantly provides recommendations that can used to fix immediate and foreseeable network performance issues.

Key Capabilities Delivered by NetInsigh

Wi-Fi Optimization with Benchmarking
Proactively optimize network performance with:

• Automatic classification of individual APs based on environmental measures such as radio propagation, AP arrangement, user behavior and traffic characteristics.

- Radio propagation attributes include path loss exponent, through-ceiling loss and number of adjacent floors

- AP arrangement attributes include AP density, AP uniformity, and AP capabilities

- User behavior attributes include user density, user mobility, connection duration, and device class mix

- Traffic characteristics attributes include load statistics, application type distribution and UL/DL ratio

• Recommendations for configuration tuning and projected impact on user experience
• Anonymized peer benchmarking based on comparative learnings against similar networks

Impact Analysis
Identify the outcome of a change on the network based on key performance indicators with:

• Event creation for marking configuration modifications and firmware updates as tracked change triggers
• Pre- and post-event comparisons for monitoring the outcome of a change for an extended period of time to validate that it has either improved performance, remained the same or regressed

Real-time Anomaly Detection
Easily detect irregularities that can be extremely difficult to identify manually, but can be early indicators of bigger problems using:

• Baseline models of "normal" based on various attributes of tracked metrics
• Automatic monitoring for inconsistent device and radio performance events and trends
• Intelligent clustering of events to focus on anomalies that will actually degrade user experience

User Connectivity Insights
Focus on what is truly impacting user experience with:

• Real-time monitoring of authentication, DHCP and Wi-Fi connectivity failures
• Automatic elimination of false positives by machine-learned roaming patterns to automatically discount irrelevant failures
• Insight-driven root cause analysis and recommendations to fix problems proactively

Aruba NetInsight empowers IT organizations with the insight needed to focus on what is most relevant and critical to the business, and continuously measure and tune network performance.
