    - Piggybacking technique is used to improve the efficiency of the bi-directional protocols.

    - Piggybacking is a bi-directional data transmission technique in the network layer of the OSI model.

    - The data frames are sent from receiver to sender and adds the confirmation, it means the acknowledgement, that the data frame sent by the sender was received successfully.

    - Sending an acknowledgement in an individual frame is piggybacked on the data frame.

    - It improves efficiency and better use of available channel bandwidth.
