Q. Function of OSI Transport Layer?

- It takes the information to be sent as well as breaks it into individual packets that are sent and reassembled into a complete message by the Transport Layer at the receiving node

- As well provide a signalling service for the remote node so that the sending node is notified when its data is received successfully by the receiving node

- Transport Layer protocols comprise the capability to acknowledge the receipt of a packet if no acknowledgement is received the Transport Layer protocol can retransmit the packet or time-out the connection and signal an error

- Transport protocols can as well mark packets with sequencing information so that the destination system can properly order the packets if they're received out-of-sequence

- Additionally Transport protocols provide facilities for insuring the integrity of packets.

- Transport protocols offer the capability for multiple application processes to access the network by using individual local addresses to determine the destination process for each data stream
