Diffusion network

from Wikipedia, the free encyclopedia

A diffusion network is a computer network in which transmitted data, regardless of their destination, propagates throughout the transmission medium. Based on the addressing of the data, the individual participants (e.g. network cards ) recognize whether they are accepting or ignoring them. In extreme cases, a message reaches all participants at the same time.

The best-known diffusion networks are public broadcasting or LANs in bus topology such as Ethernet . Networks in which a broadcast reaches all participants are also referred to as broadcast networks.

In a diffusion network, every node is connected to the common transmission medium and can therefore read every data packet. If individual participants should not be able to read certain data packets, they must be encrypted before they are sent. Another problem is the shared bandwidth, as usually only one station is allowed to transmit at the same time.

Other examples of diffusion networks are the ring and bus topologies .
