The document outlines the Named Data Networking (NDN) project, a proposed architectural blueprint for a new internet protocol. The project, led by a team from various universities and research institutions, aims to address the limitations of current internet protocols, particularly in content distribution and security. NDN introduces a data-centric approach where data is identified by names rather than IP addresses, allowing for more flexible and efficient content distribution. Key features of NDN include: 1. **Data-Centric Security**: Data is signed with a producer's key, ensuring end-to-end security and allowing for fine-grained trust management. 2. **Routing and Forwarding**: NDN uses hierarchical names for routing, eliminating issues like address exhaustion, NAT traversal, and scalability problems. It supports multipath routing and forwarding, enhancing network resilience and load balancing. 3. **Caching**: NDN routers cache data packets, enabling efficient content distribution, multicast, and mobility. 4. **Pending Interest Table (PIT)**: The PIT stores pending Interests, facilitating efficient data delivery and DDoS attack mitigation. 5. **Transport**: NDN moves transport functions into applications, simplifying network management and improving reliability. The project also outlines a research agenda focusing on scalable routing, fast forwarding, and application development. The team plans to extend existing routing protocols and develop new mechanisms for efficient name lookup and forwarding. They emphasize the importance of user-centric security, privacy, and competition in the network. Overall, NDN aims to realign the internet architecture with application needs, enhancing security, efficiency, and user choice.The document outlines the Named Data Networking (NDN) project, a proposed architectural blueprint for a new internet protocol.
