RadioDNS — The Missing Link?
[excerpt]
http://rwonline.
A number of prominent and forward-thinking U.K. broadcasters have been at
work on a proposal for standardizing how to access radio services'
program-associated online resources, and the proposal is now seeing wider
promulgation.
It is called RadioDNS, applying the familiar "Domain Name System" used for
locating resources on the Internet.
For those unfamiliar with the process, in simple terms the Domain Name
System is the equivalent of a distributed "phone book" or "directory
assistance switchboard" for the Internet. When a user types a Web address
into a browser, the query goes first to DNS, which essentially redirects
the connection to the server that holds the desired content.
DNS knows where to send the user's query because it is a hierarchically
structured system that can quickly poll all the name servers on the
Internet to quickly determine where the sought content is stored, and once
located, route the user's connection to that server.
This network of name servers constantly is updated with the latest
resource identification and location records by the appropriate
registration agencies, and any such updates entered into any one name
server are soon propagated throughout the entire DNS.
