Chapter 11: Cisco Content Networking and Video Solutions

OVERVIEW

As the Internet continues to be a place rich with multimedia, it's apparent that an organization's single server cannot bear the entire burden on its own. For example, when hundreds of users from around the country try to access the multimedia content at a site located on a server in Kansas City, the results will be less than optimal.

However, if the content of that server were to be replicated and colocated in Seattle, New York, Chicago, Atlanta, Kansas City, and Reno, then users could get faster access to the material with fewer burdens on the network. This type of network is known as a content delivery network ( CDN ), and is gaining popularity with organizations that seek high availability from their internetworks.
