Proxy cache networks-traditional content distribution networks (CDNs)-which were designed and optimized for caching images, have been highly effective over the last decade in pushing the Internet forward. Without them, our experience on the early Internet would have been unbearable.To work effectively and inexpensively for millions of online users, servers needed to be hosted  at each of the points where users dialed in (or PoPs) on an ISP's network. With thousands of ISPs, each with hundreds of POPs, tens of thousands of servers were required for a CDN to provide adequate coverage.

This white paper outlines the limitations of  proxy cache networks given their legacy design and current media demands.  It also presents the attributes and benefits of an ideal solution, and suggests that BitGravity has designed a content delivery system with the attributes and benefits that provide companies and organizations with a superior solution that addresses the needs in marketplace at an affordable price.
