It is to provide the communication services directly to the application processes running on different hosts.
(a)
The transport layer transmits the entire message to the destination.
End-to-end delivery
Addressing
Reliable delivery
Flow control
It is used to prevent the sender from overwhelming the receiver. If the receiver is overloaded with too much data, then the receiver discards the packets and asking for the retransmission of packets.

Message Integrity
End-point authentication
Non-Repudiation
Aspects of Network Security: means that the data must arrive at the receiver exactly as it was sent.

Message Integrity
End-point authentication
Non-Repudiation
Aspects of Network Security: means that the receiver is sure of the sender?s identity, i.e., no imposter has sent the message.
Privacy
Message Integrity
End-point authentication
Non-Repudiation
Aspects of Network Security: means that the receiver must be able to prove that the received message has come from a specific sender.
