The program staff involved with the project at NSF stress that the FIA program is just one step toward an improved internet of the future.
It has evolved from a small scale network of networks to become integral to our lives and vital to the operation of all critical sectors of our society.
The continued success of the Internet, however, is increasingly threatened by the ever-mounting sophistication of security attacks and by the lack of performance reliability of Internet services.
By naming data instead of their location (IP address), NDN transforms data into first-class entities.
While the current Internet secures the communication channel or path between two communication points and sometimes the data with encryption, NDN secures the content and provides essential context for security.
Dealing with mobility as a first class entity allows functionalities like context--and location--aware services to fit naturally into the network.
The project focuses on the tradeoffs between mobility and scalability and on opportunistic use of network resources to achieve effective communications among mobile endpoints.The architecture uses generalized delay-tolerant networking (GDTN) to provide robustness even in presence of link/network disconnections.GDNT integrated with the use of self-certifying public key addresses provides an inherently trustworthy network.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.Recognizing the need for a secure and highly dependable information technology infrastructure and building on NSF's on-going investments in network science and engineering, the Directorate for Computer and Information Science and Engineering (CISE) has formulated this program to stimulate innovative and creative research to explore, design, and evaluate trustworthy future Internet architectures.For those who are interested, the final report on the summit, with an extensive discussion of the ideas that were discussed, can be found here.
