Study Notes
Transport Layer Responsibilities
- The primary responsibility of the transport layer is to ensure reliable data transfer between hosts.
Transport Layer Protocols
- TCP (Transmission Control Protocol) operates in a connection-oriented and reliable manner at the transport layer.
- UDP (User Datagram Protocol) is a connectionless transport protocol.
Transport Layer Functionalities
- The main functionalities of the transport layer include multiplexing and demultiplexing.
Connection-Oriented vs Connectionless Protocols
- Connection-oriented protocols transmit segments to the receiver in the same order the sender has sent them, ensuring reliability and order.
- Connectionless protocols do not establish a dedicated connection before transmitting data, and do not guarantee the order of segment receipt.
TCP Specific Features
- TCP uses a handshake process to establish a connection between devices.
- TCP provides reliable data transfer, a feature not available in UDP.
Multiplexing Purpose
- The purpose of multiplexing at the sender's side is to collect messages from multiple sockets and add transport headers to be used later in demultiplexing.
TCP vs UDP
- The main difference between TCP and UDP in terms of data transfer is that TCP is connection-oriented and reliable, while UDP is connectionless and unreliable.
