FIELD: information technology.
SUBSTANCE: invention relates to telecommunication technologies. Technical result is achieved by providing label in header of each data packet to be transmitted between specified part of network nodes, label that includes following fields: packet destination node identifier, packet data priority class identifier, identifier of packet sender-node, identifier of packet sequence number in corresponding data priority class, ensuring distribution of data packets between specified part of network nodes by sending each data packet along one or more routes between sending node and receiving node, creating, on each of specified part of network nodes, table of received packets containing records with information about each unique packet of data received by that node, and comparing information from header of each data packet to be transmitted between said part of network nodes, with entries of received network packet table of network node from specified part of network nodes and preventing transmission of packet by this node of network if information from specified header matches the received packet table record.
EFFECT: technical result consists in providing routing and classification of data packets in network.
