Content Delivery Networks – Delivered by Level 3

Content Delivery Network (CDN) Services offer caching and download as a reliable delivery method for digital content distributed on the Internet. The growth and popularity of digital media has created a new set of challenges for today’s web businesses. With the continued adoption of broadband Internet, file sizes have grown exponentially along with the quantity of content available from popular websites.

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 unacceptable risk into ensuring exceptional end user experiences. Whether it is a whole site, or an individual file (video, software, patch, etc.), your business will benefit from a content delivery service through increased performance and reduced digital delivery costs.

• Object delivery – The most commonly used method to deliver content such as patches, file downloads, and multimedia content to large audiences. Objects can be tagged for complete control over delivery, authentication, and content freshness. Extended aliases can also be used to address more than one origin server using the same domain. This facilitates brand consistency as end users retrieve content from a customer’s domain regardless of the origin, allowing customers to have multiple servers for redundancy and content-staging purposes.
• Total site delivery – The suite of services can be easily configured to serve all resources, like images, ActiveX and Flash for a particular domain name. This requires no modification to the origin server and can often be implemented with no rewriting of HTML.
• Secure delivery - Level 3 offers flexible solutions for the delivery of HTTPS content. By off-loading SSL tunnel setup and persistence to the Level 3 CDN, customers can effectively relieve the SSL burden from their Web sites. This not only increases performance, but allows Web servers to handle the delivery of non-cacheable objects such as dynamic content, server-side applications, and database activity. Customers can opt for full integration with the use of a custom SSL certificate that matches their domain, or utilize a more economical shared certificate if they simply require the security of HTTPS.

Capacity on Demand – The Level 3 CDN proactively monitors resources to meet usage demands that customers place on your web operations. Flexible capacity enables cost efficiency in operation while reducing the cost of managing your website and improving performance.

Global Coverage – Server clusters in strategic locations in North America, Europe and Asia ensure top performance to destinations across the globe. Level 3 is one of the world’s most connected ISP’s 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.

Scalability – The Level 3 CDN has the capacity to handle content delivery even during peak loads and flash events that require extra bandwidth to accommodate growing libraries of content and audiences of any size.

Online Management Portal – A web-based management portal allows for historical usage reporting and real-time usage monitoring. Usage logs are available via automated download tool and real-time invalidation of content can be controlled through portal or scriptable interface.

Flexibility – Support for multiple distribution options and file types including software downloads, large file delivery, bit-range requests, download receipts and secure delivery options. Security – HTTPS support for shared and custom SSL certificates.

Dual Provider Capabilities – Balance traffic and multi-home with other CDN providers easily and reliably with Level 3’s Intelligent Traffic Manager (ITM) Service.
