Abstract: Reception information of frames received at a redundant port may be stored to a data structure in group of data structures such that reception information of all frames in a sequence are not stored to the same data structure and the reception information can be quickly accessed for duplicate detection. The data structure includes reception information for a portion of consecutive frames in a sequence of frames transmitted by a specific transmitter node. A communications layer address of the transmitter node and information capable of identifying a portion of consecutive frames in a sequence of frames are derived from a received frame. The reception information for the received frame in the data structure is read on the basis of derived information capable of identifying the received frame within the portion of consecutive frames.
