Group address

from Wikipedia, the free encyclopedia

Group addresses are special addresses e.g. B. in telecommunications or network technology or even electrical engineering in general. They allow data to be sent to all members of a group. They are mostly implemented on the lowest hardware level in order to be able to work efficiently. Group addresses are often assigned dynamically (via software / configuration).

Example broadcast

From the field of computer networks , the broadcast can be named here. A sender does not send its data to a specific network address (or IP address ), but to a group address , the broadcast address . Thus u. a. ensures that the message / data are sent quasi in parallel and are not processed sequentially .

Example clustering

A higher level implementation is available e.g. B. in clustering . Here z. B. several nodes belong to a group that has a group address via which all members of this group can be addressed.

Example electrical engineering

With modern bus systems in today's electrotechnical systems, group addresses help to e.g. B. to switch on all lamps in hall XY or to activate certain patterns in a light emitting diode matrix.
