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

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
