CDN Tiers
• Tiered or distributed networks are necessary if it is
not practical to serve all users from one central point
due to:
– Bandwidth limitations
– Scalability needs
– Speed of light limitations
– Redundancy needs
• Typical tiers
– Tier-1 (Super headend)
• Central Site – main ingest, library & distribution point
– Tier-2 (Regional headend)
• Regional content, redundant feeds, distribution/propagation point
– Tier-3 (Edge site/POP, etc.)
• Caching & streaming for popular content, reduced core bandwidth
