Distance learning involving corporate training or consumer education. When content needs to be multicast to massive numbers of consumers, the most efficient way to do it is to move the data to the network edge to be closer to the consumer. Proxy servers can both cache content to meet user requests and collect requests from users for forwarding over the Internet. Content can be sent to these servers via satellite, cable or other links and constantly refreshed. Cache worth paying for A prime caching application is to push entire Web sites out to caching servers.
Consumers can then pull the data from the server.
Going wireless Another prime caching opportunity involves WAP-enabled applications. WAP, or the Wireless Application Protocol, provides a standardized way for wireless devices to gain Internet access, thus opening the door to interoperability. Services can be built based on sending predictable types of content such as news and weather to be sent to local WAP-enabled caching servers. From there the content can be beamed to GSM-based wireless devices. The downlink would be via DVB-T while GSM could provide the back channel.
