A device in a server having a processor and a storage. The device has a protocol blind network path indication unit configured to obtain an indicator corresponding to a predetermined path to a data communication unit in the network using a destination address of a received data packet, an upstream communication unit configured to transmit a network protocol blind packet including the data packet and the indicator corresponding to the predetermined data path to the data communication unit in the network, a combiner configured to bind the indicator to the data packet received by the downstream communication unit, and a protocol blind correlation storage unit configured to provide information related to target addresses and indicators corresponding to a plurality of predetermined data paths in the network. The protocol blind network path indication unit obtains the indicator corresponding to a predetermined path by accessing the protocol blind correlation structure.
