Disclosed is a scalable, hierarchical, distributed network architecture and processes for the delivery of high-performance, end-to-end online multimedia services, including Internet services such as World Wide Web access. The network architecture connects a high-speed private backbone to multiple network access points of the Internet, to a network operation center, to a back office system, and to multiple regional servers in regional data centers. Each of the regional servers connects to several caching servers in modified head-ends, which in turn connect via fiber optics to many neighborhood nodes. Finally, each node connects via coaxial cable to multiple end-user systems. The processes include those for replicating and caching frequently-accessed content, and multicasting content customized per region or locality.
