Content must be gathered from content providers, aggregated and filtered before pushing to the subscriber's end. Is there a cure for this?
Yes, multicasting, Mr John L Stevenson, CTO Orblynx, said at the Internet technologies Forum of IIW 2000 on Friday. Multicasting can be defined as the ability of one host to transmit data to multiple servers at the same time.

Parallel distribution.

It is quite the opposite of point-to-point methods. Since only one copy is being sent to all the servers, there are substantial savings in bandwidth costs and the time it takes to reach the end user.

Multicasting, as advocated by Mr Stevenson, relies on caching technology. Conventional caching servers hold only the most popular data. In the multicasting solution, caching servers at the ISP (Internet service provider) hold a copy of the entire site so that requests from users in one part of the world don't have to hop from server to server to retrieve the information.

The methodology followed in multicasting employs a satellite to transmit the data to a caching server at the ISP, which then provides the content to the subscriber. That is, content from the content providers is pulled to a warehouse, which then pushes the information to the caching server, which ultimately services the end-user.

The benefits to the end user are tremendous: fewer hops are needed, less ISPs are involved, the bandwidth is saved, and ultimately subscribers pay much less - almost one-fifth of the cost of conventional methods.
