SES & WINLAB Satellite CDN Overlay Demonstrator
• Hybrid terrestrial-satellite network architecture.
• Combines satellite’s wide coverage areas, ubiquitous
access, and broadcast-ability with intelligent routing,
caching, and popularity metrics.
• Satellite solutions with greater network awareness
and intelligence are needed to differentiate our
service offerings in the marketplace.
Key Characteristics:
• Efficiency: satellite multicast replaces terrestrial
unicast, content caching
• Awareness: traffic demand, content popularity
• Intelligence: intelligent traffic routing, data
driven cache management
• Performance: edge storage improves experience –
lower latency, higher QoS
