Score Perspective

Sandvine's Score Perspective enables a unique solution, Network Experience Scoring. It simplifies the visualization of network quality metrics, making it easier for Engineering and Executives to make the right investment decisions to improve their subscriber’s experience.

Score Perspective measures each subscriber’s throughput, latency, and packet loss at sub-second intervals to gauge the ability of the network to deliver a high quality experience to the subscriber. The scoring reflects the performance during peak usage applied to the expectations for each application class - Web Surfing, Streaming Video, Social Media, Real-time Gaming, Upload, Download and Voice Applications. The measurements include location, device, and service plan to provide context for each subscriber’s traffic.

Score Perspective can be deployed on any PacketLogic Real-Time Enforcement platform - virtual or hardware-based - in active or passive mode in the operator’s network. The performance impact of deploying Score Perspective on a PRE is minimal, enabling pervasive deployment throughout an operators network.

The intelligence collected in Score Perspective is visualized in the PacketLogic Insights product family. Engineering Insights has an interactive drilldown capability to enable root cause analysis for why a score is bad and where the optimal investments can be made to improve network quality for subscribers.

High-value use-cases

Maximize ROI for CAPEX for Improving the Subscriber Experience
Interactive drilldown to determine the root cause of low network scores. Scores can be filtered by “problem contributors” to display how many subscribers are affected by network issues.

Executive Dashboards
Gain insights into your overall network performance in easy to understand metrics for executives.

Service Plan Creation
Target your marketing towards the applications that your network excels at delivering a high QoE to subscribers.

Network Quality Assurance
Ensure that your network is delivering a high quality of experience for your subscribers

Service Marketing
Market your services based on the Score for specific application types - “Our network delivers an A for Video!”

Score Methodology

Score Perspective is based on Sandvine's 15 years of experience with applications and their performance on broadband networks. A network that has a high throughput may not meet the needs of a subscriber that is interested in gaming or voice applications, as they require low latency and low packet loss. Score Perspective measure the three most important factors in a consumers broadband experience at sub-second intervals:

• Throughput – Measured at all times, scored at peak, not an instantaneous “Speed Test” that can be affected by congestion or other network policies
• Latency – Measured for each connection to detect the round trip time for delay-sensitive applications like gaming and voice applications
• Packet Loss – Measured to determine efficiency of network and impact on loss-sensitive applications like interactive audio and video

The scoring methodology is updated yearly to account for changes in broadband technology and in application behavio r. Encryption has no effect on scoring, as the same metrics apply to traffic whether it is encrypted or not, and Sandvine’s Traffic Perspective has advanced heuristics to identify applications using encryption technology. A network score is comparable anywhere in the world, and comparable between fixed and mobile networks, enabling a consumer to assess if a mobile connection can meet their needs to replace a fixed line connection for their preferred applications. Network Operators using Scorecard will be able to maximize the ROI for their network investments for improving the subscriber experience.
