A service provider that has created its own worldwide network (or portfolio) of Web sites. It distributes Web site content to customers. Primarily for streaming content, a CDN has the bandwidth capabilities to deliver rich media in a clear, non-jerky manner. It is also a logical solution for delivering streaming content to a large, geographically dispersed audience. Costly and complex, a CDN requires content access point (CAP) architecture that integrates content distribution, storing, caching, streaming, searching, verification, and sorting capabilities.
