Skyfire Confidential and Proprietary

A New Approach to Optimization Best-in-Class Performance

Old Approach: Caching and transrating solutions delivering small savings across all traffic Skyfire Approach: Real-time, full transcoding targeted when and where needed; delivering average 64% savings

Surgical Control

Cloud Economics

Old Approach: In-line gateway proxy for all traffic. Rooms full of boxes, hard to scale for LTE or HD Skyfire Approach: intelligent traffic steering from existing network elements enables conditional proxy to efficient cloud optimization platform

Old Approach: “carpet bombing” optimization across entire network; expensive, bad user experience, lower ROI Skyfire Approach: “laser guided” targeting of optimization based on policy. Delivers best user experience possible with available network

Skyfire Vendor B

Video Optimization Savings

Based on Customer testing:

Skyfire generates 2X the savings compared to leading optimization vendor

…while maintaining superior visual quality

Thanks to Unique Video IP and Cloud Architecture

Most Advanced Media Adaptation Engine

Cloud allows Skyfire to offer Transcoding at a Transrating Price

Skyfire: Up to 80% optimization (target configurable)

Smooth frame rate reductions (Pixel domain)

Can change resolution, codec, and audio sampling rate

More compute intensive, offset by cloud architecture

Legacy: Max. 25% (open loop) or 40% (closed loop optimization)

Choppy frame rate reductions (Compressed domain)

No resolution or audio change: 720p video remains 720p video

Less compute intensive, but much less savings
