    An upper-layer, connection-oriented protocol or service

    Explanation:

    Connectionless acknowledgements are used to request retransmission.

    Upper-layer connection-oriented protocols keeps track of the data received and can request retransmission from the upper-level protocols on the sending host.

    A Network layer IP protocols manage the communication sessions if connection-oriented transport services are not available.

    The best-effort delivery process guarantees that all packets that are sent are received.

    Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on the sending host.
