Named Data Networking (NDN) (related to content-centric networking (CCN), content-based networking, data-oriented networking or information-centric networking (ICN)) is a proposed Future Internet architecture that seeks to address problems in contemporary internet architectures like IP.
Streaming – Data is read as a byte stream, no distinguishing indications are transmitted to signal message (segment) boundaries. User Datagram Protocol is a simpler message-based connectionless protocol. Connectionless protocols do not set up a dedicated end-to-end connection.
Names can be location-independent and are much more adaptable than IP addresses. Network elements can make more advanced choices based on the named requests and data. Scalable - CCN enables the network to scale by allowing caching, enabling native multicast traffic, providing native load balancing, and facilitating resource planning.
The network automatically replicates datagrams as needed to reach all the recipients within the scope of the broadcast, which is generally an entire network subnet. Multicast delivers a message to a group of nodes that have expressed interest in receiving the message using a one-to-many-of-many or many-to-many-of-many association; datagrams are ...
Network delay is a design and performance characteristic of a telecommunications network. It specifies the latency for a bit of data to travel across the network from one communication endpoint to another. Delay may differ slightly, depending on the location of the specific pair of communicating endpoints.
RDMA supports zero-copy networking by enabling the network adapter to transfer data from the wire directly to application memory or from application memory directly to the wire, eliminating the need to copy data between application memory and the data buffers in the operating system.

A data unit at layer 2, the data link layer, is a frame. In layer 4, the transport layer , the data units are segments and datagrams . Thus, in the example of TCP/IP communication over Ethernet , a TCP segment is carried in one or more IP packets , which are each carried in one or more Ethernet frames .
