Caching and Download
The growth and popularity of digital media has created a new set of challenges for today’s online businesses; file sizes as well as quantity and type of content has grown exponentially, consumers expect a continually richer web experience (video, music, software) driving rapid and at times erratic growth in site traffic. Traditional delivery methods are less effective, more costly, and put unwanted risk into ensuring a positive end user experience. Whether it is a whole site, or an individual file, video or software patch, your business will benefit from a content delivery service through increased performance and reduced digital delivery costs.

Key Service Features
Capacity on Demand: The Level 3 CDN proactively monitors resources to meet usage demands that customers place on your web operations. This flexible capacity improves cost efficiencies by reducing operational overheads and lowering the cost of providing customers with enhanced performance.

Coverage: Level 3 is one of the world's most connected ISPs with fewer than 1.77 hops to any destination. This means that you can count on your content being served close to your end user whether they are in Europe, the US or Asia.

Scalability: The Level 3 CDN has the capacity to handle content delivery even during peak loads and ‘flash’ events that require extra capacity.

Flexibility: The CDN supports multiple distribution options and file types including software downloads, large file delivery and download receipts and secure delivery options.

How it works
- Frequently requested content (images, flash files, video, music, software etc.) is copied and hosted across Level 3’s CDN server infrastructure. Distribution of content is aligned with regional demand for that content.
- Routing technology intelligently establishes the location of the end customer, and selects the optimal cache node to serve that customer based on the network conditions existing between the Level 3 network and the customer.
- Caching and Download provides online operations with a demand-based presence on the edge of the Internet at major private and public peering locations to suit their business.
