University of Arizona researchers are participating in a U.S. National Science Foundation (NSF) effort that is investigating ways to revolutionize the Internet's architecture. The Named Data Networking (NDN) project is working to take the focus off the TCP/IP connection and place it on the data being transmitted. Changing the Internet's basic structure could solve issues related to application development, content delivery, mobility support, network trustworthiness, and security.
"As our reliance on a secure and highly dependable information technology infrastructure continues to increase, it is no longer clear that emerging and future needs of our society can be met by the current trajectory of incremental changes to the current Internet," says NSF's Ty Znati.
"We want a model that fits application and user needs to ensure that application development is easier and that there also is more efficient content delivery," says Arizona professor Beichuan Zhang. The new architecture also will have applications in electronic commerce.
NDN will aid in improved content delivery and security by identifying the actual data by unique names and carry authentication information.
