ABSTRACT:
The invention relates to a method and a system for communication in a data network (101), in particular switched Ethernet, and a user (102) in such a data network (101). To reduce the communication resources required for the transmission of telegrams (119-135) in the data network (101), it is proposed that time segments are defined, which are repeated cyclically at a basic clock rate, that telegrams (119-135) are each assigned a first identifier U, which allocates to the respective telegram (119-135) a group of n successive time segments for transmission of the respective telegram (119-135), whereby the group is repeated cyclically, that the telegrams (119-135) are each assigned a second identifier Z, which allocates to the respective telegram (119-135) an mth time segment in the sequence of n time segments of a group for transmission of the respective telegram (119-135), whereby 1≦m≦n and that the telegrams (119-135) are transmitted in the respectively assigned time segment.
