INTEREST
DATA
NDN: Focusing on retrieving data
Collaborators: UCLA, UCSD, UIUC, Univ of Michigan, Colorado State Univ, Univ of Arizona, Univ of Memphis, Washington Univ at St.Louis
Developed over 6 years – now available for commercial testing
![Page 7: Wireless Research @ NSF - 5G and beyond - Federal ... 5G Workshop Pane… · Wireless Research @ NSF - 5G and beyond Thyaga Nandagopal Program Director, National Science Foundation](https://reader031.fdocuments.us/reader031/viewer/2022022601/5b478bf37f8b9af54b8c40e6/html5/thumbnails/7.jpg)
NDN’s role in 5G architectureNamed Data Networking focuses on data itself instead of the connections or locations of data, making 5G networks secure, efficient, scalable, and robust in data dissemination.
♢ Securing data directly, which enables ultimate data protection and trustworthiness in mobile environments where connectivity can be rich yet intermittent and data retrieved from middleboxes NDN team has developed solutions toward automating trust management and data
verification
♢ Facilitating mobility: Identifying and retrieving desired data, instead of maintaining connection with a moving target.
♢ Utilizing multiple interfaces and multiple paths to achieve efficiency and robustness in data delivery.
♢ Scalable content distribution via native in-network caching and multicast
