CNN has an AP report on the still-evolving Internet:
While engineers tinker with the Internet’s core framework, some university researchers looking for more speed are developing separate systems that parallel the Internet. That way, data-intensive applications like video conferencing, brain imaging and global climate research won’t have to compete with e-mail and e-commerce.
nternet2, with speeds 100 times the typical broadband service at home, is now limited to selected universities, companies and institutions, but researchers expect any breakthroughs to ultimately migrate to the main Internet.
While Internet2 and LambdaRail seek to move data faster and faster, researchers with the World Wide Web Consortium are trying to make information smarter and smarter. Semantic Web is a next-generation Web designed to make more kinds of data easier for computers to locate and process.
Consider the separate teams of scientists who study genes, proteins and chemical pathways. With the Semantic Web, tags are added to information in databases describing gene and protein sequences. One group may use one scheme and another team something else; the Semantic Web could help link the two. Ultimately, software could be written to process the data and make inferences that previously required human intervention.
With the same principles, searching to buy an automobile in Massachusetts will also incorporate listings for cars in Boston.
