A node NI has a protocol stack (10), between application (13) and management (11) layers, and two or more Link level interfaces (12, 14) to network links (31, 32). Protocol stack (10) has a multiple data link interface (101), which may duplicate packets at transmission, to be sent through links (31, 32), respectively. A memory area is reserved. At reception, an identifier (X) is calculated for each incoming packet e.g. form its IP header, and is searched in at least a portion of the reserved memory area; if X is not found (or not found for the source node), the packet identifier (X) is stored in currently reserved portion of the memory area.
