Abstract

Requests for content such as large multimedia files are redirected to avoid congestion and delivery delays on network backbones. In embodiments, user requests for content are redirected from the content provider'"'"'s site to a network node proximate to the user. The content is served to the user without using the backbone of the Internet. In embodiments, content items are distributed to edge nodes proximate to users by satellite or other system substantially separate from the Internet. The engines for receiving and redirecting user access requests for content may be updated in near real time with information such as content disposition, node operational status and user addresses and profiles.

The processor of claim 171, wherein the service point comprises a smart probe and a smart proxy agent wherein the smart probe communicates with the smart proxy agent using a site-scoped multicast message, and the smart proxy agent communicates with the central messaging and control mechanism.
  - 173. The processor of claim 122, wherein the service point comprises a smart switch and a plurality of servers;
    - and the user is redirected to the smart switch, wherein the smart switch selects one of the plurality of servers for serving the content item.
  - 174. The processor of claim 122, wherein the user is redirected to a service point responsive to a container file.
  - 175. The processor of claim 174, wherein the container file is processed at a service point.
  - 176. The processor of claim 122, wherein the user address database comprises user class information associated with the user, and the user is redirected to the service point responsive to the user class information associated with the user.
  - 177. The processor of claim 122, wherein the content item database comprises service class information associated with the content item, and the user is redirected to the service point responsive to the service class information associated with the content item.
  - 178. The processor of claim 177, wherein the user address database comprises user class information associated with the user, and the user is redirected to the service point responsive to the user class information associated with the user.
  - 179. The processor of claim 122, wherein a special service code is issued to the user.
  - 180. The processor of claim 179, wherein the special service code is responsive to user profile information associated with the user.
  - 181. The processor of claim 179, wherein the user access request further specifies the special service code.

64. The system of claim 1621, wherein the second network comprises a satellite telecommunications system.

122. A processor comprising program logic configuring the processor to receive, via a first network, a user access request generated by a user, the user access request comprising a specification of a content item of a plurality of content items and a user address, associated with the user, of a plurality of user addresses;
- and determine, responsive to the specification of the content item and the user address, a service point of a plurality of service points;
  
  wherein a user address database relates the plurality of user addresses to the plurality of service points, and a content item database relates the plurality of service points to the plurality of content items; and
  
  wherein each of the plurality of content items is distributed, prior to receipt by the processor of the user access request, to at least one of the plurality of service points using a second network substantially separate from the first network.

182. A system for redirecting computer network users comprising:
- means for receiving, using a first network, a user access request from a user, wherein the user access request comprises a specification of a content item of a plurality of content items and a user address of a plurality of user addresses; and
  
  means for redirecting the user, using a first network, to a service point of a plurality of service points, responsive to the specification of the content item and the user address;
  
  wherein a user address database relates the plurality of user addresses to the plurality of service points, and a content item database relates the plurality of service points to the plurality of content items.

183. A processor comprising program logic configuring the processor to receive, via a first network, a user access request generated by a user, the user access request comprising a specification of a content item of a plurality of content items and a user address, associated with the user, of a plurality of user addresses;
- and determine, responsive to the specification of the content item and the user address, a service point of a plurality of service points;
  
  wherein a user address database relates the plurality of user addresses to the plurality of service points, and a content item database relates the plurality of service points to the plurality of content items.
