Content delivery networks


How does a CDN address it?What's the primary issue a CDN addresses?

Spread the load!A central point serving a vast audience…

R hi i i l


p• Get content closer to the audience

• Reaching critical mass• Single point of failure• Poor audience experience

Put Content into the CDN


Users requests content

CDN gets content where needed

CDN delivers content

Level3 versus other CDNs

Differentiator Why it MattersLevel 3 owns the Network Level 3 is the most connected network in the world – we control the

routes and hand traffic off directly to last mile eyeball networks and don’t need to rely on other transit providers and their routing policies

Capacity on Demand Level 3 builds headroom well in advance of needs through capacity planning, including redundant connectivity, added in 10Gbps and 40 Gbps increments

Strategic Network Visibility Level 3’s CDN nodes are strategically located in our gateways to position capacity closest to the points at which traffic is exchanged with eyeball networks or peers

Traffic Control All Level 3 customer traffic is carried on our network which means we can directly manage performance

Patented Intelligence • Level 3 has patented intelligence built into our CDN platform to ensure content is served from optimal CDN nodescontent is served from optimal CDN nodes

Intelligence optimizes distance, network congestion and server load which means Level 3 CDN traffic traverses fewer network hops than CDN’s that do not own their own networks and buy transit from Level 3• ITM module, means that Level3 CDN can interoperate with other CDN


Business Intelligence Level 3 invested heavily in reporting to provide industry-leading Content Analytic tools that are extremely flexible
