Transport Layer in OSI Model: The Transport layer implements reliable data transport services. The different functions of Transport Layer are illustrated below:
• The transport layer is meant for transmitting the data and keeps an eye on sender device so that it may not send much data than receiving device actually needed.
• The sliding window states how much data packets can be received by the destination point at a time.
• Data from some applications are transmitted on to a single physical link.
• Transport Layer offers services for checking error and it too facilitates error handling techniques.
