Systems like Local Area Networks for redundantly exchanging information parts between source nodes ( 1 ) and destination nodes ( 2 ) via different physical links ( 4,5 ) are simply constructed by introducing in the source node ( 1 ) source interfaces ( 13,14 ) and by introducing in the destination node ( 2 ) destination interfaces ( 23,24 ) and address detectors ( 52,53 ) for detecting source interface addresses in information parts and selectors ( 51 ) for in dependence of detected source interface addresses selecting one destination interface ( 23,24 ) for non-redundantly processing one of the redundantly exchanged information parts. The source interfaces ( 13,14 ) are defined by identical source interface addresses, and the source nodes ( 1 ) comprise suppliers ( 41 ) for supplying information parts comprising identical data parts to the source interfaces ( 13,14 ). The destination node ( 2 ) comprises monitors ( 54,55 ) for monitoring information parts received via the destination interfaces ( 23,24 ) and generators ( 56,57 ) for in response to monitoring results generating link parameters per physical link ( 4,5 ) and comparators ( 58,59 ) for comparing link parameters with thresholds for in response to comparison results controlling the selectors ( 51 ).
