NDN (Named Data Networking)
Definition of NDN
NDN (Named Data Networking) is a network architecture that aims to replace the host-based communication model commonly used on today's Internet with a content-based model. In NDN, traditional IP addresses are replaced by data names, and data becomes the center of communication, rather than the location or address of a host.
The Bachelor of Telecommunication Engineering Study Program, Telkom University Jakarta Campus, held sharing session v.6 on the topic of NDN. The speaker for this BTE-JC Sharing Session was Ms. Ade Nurhayati, S.T., M.T., currently a lecturer in the D3 Telecommunication Engineering program at TUJ who will later join the BTE-JC family.
The BTE Sharing Session “with Bu Ade” held on 23 December 2023 had the theme “NDN as the Future Internet Architecture”.

In outline, the essence of this BTE Sharing Session is:
NDN stands for Named Data Networking, an internet architecture that differs from the Internet Protocol (IP)-based architecture.
NDN can be called the future internet architecture, as it can change the perspective in networking from host-centric to data-centric. NDN has advantages over IP-based networks, such as a caching algorithm that regulates how data from content providers or producers is stored.
Some key concepts of Named Data Networking (NDN) include:
- Data Names: Data names are used as addresses to identify and find data in the network. For example, instead of using an IP address or URL, NDN uses data names that can reflect the requested content.
- Caching: NDN uses the concept of caching at every node in the network. When data is requested, a node that holds it can store a copy of that data. This allows users to get data from the nearest node rather than always communicating with the origin server, improving efficiency and reducing server load.
- Name-Based Routing: Routes in NDN are not tied to the host's IP address, but to the data name. This means the address (data name) determines the delivery route, not the IP address of the device storing the data.
- Name-Based Security: Security is implemented by exploiting the uniqueness of data names. Each piece of data has a unique name and a digital signature, making it easy to verify the authenticity and integrity of the data.
- Content-Centric: The NDN approach focuses on content rather than hosts. Users define what they want by specifying a data name, and the network works to provide that data, regardless of where it is located.
NDN is being developed as part of an initiative to find solutions to problems arising in the current Internet model, such as scalability, security, and content distribution. Although it is still in the development and experimentation stage, NDN has the potential to bring fundamental changes to how networks and data communication are organized on the Internet.
Thank you for the presentation in the BTE Sharing Session, and thank you also to the committee and participants for taking part in this webinar.
See ya next sharing session
