Delivering Multimedia Services
First Claim
1. A system for delivery of multimedia services comprising:
- at least two regional servers, each coupled to a high-speed network backbone carrying content, the at least two regional servers including a first regional server and a second regional server which each provide a second level of caching for content received from the high-speed network backbone, the first regional server configured to customize content received from the high-speed network backbone to form a first version of multicast content and the second regional server configured to customize content received from the high-speed network backbone to form a second version of multicast content;
at least one regional subscription server coupled to at least one of the first and second regional servers, the regional subscription server adapted to track services subscribed to by end-user systems; and
a plurality of caching servers, including a first caching server coupled to the first regional server and a second caching server coupled to the second regional server, each caching server configured to provide a first level of caching of content for an end user system in a region served by the regional server to which it is coupled, and to provide the customized multicast content formed by the coupled regional server to the end-user system.

Abstract
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.

15. A system for delivery of multimedia services comprising:
-
a first regional server coupled to a high-speed network backbone, the first regional server providing a second level of caching for content received from the high-speed network backbone and customizing the received content to form a first version of multicast content; a second regional server coupled to the high-speed network backbone, the second regional server providing a second level of caching for content received from the high-speed network backbone and customizing the received content to form a second version of multicast content; at least one regional subscription server coupled to at least one of the first and second regional servers, the regional subscription server adapted to track services subscribed to by end-user systems; a first caching server coupled to the first regional server, the first caching server providing a first level of caching of content received from the first regional server and providing the first version of multicast content to an end-user system in a region served by the first regional server; and a second caching server coupled to the second regional server, the second caching server providing a first level of caching of content received from the second regional server and providing the second version of multicast content to an end-user system in a region served by the second regional server. - View Dependent Claims (16, 17, 18, 19, 20)
