  • The link that connects the Transport and Network Layers. The transport layer is located just above the network layer in the protocol stack.
  • A network-layer protocol communicates logically between hosts, whereas a transport-layer protocol communicates logically between processes running on different hosts.
  • The transport layer provides mechanisms such as error control, flow control, and congestion control to keep track of data packets, check for errors and duplication, and resend information that fails delivery.
  • The transport layer ensures communication reliability through flow control, segmentation, and error control.
  • Transport protocols such as TCP (as in TCP/IP) and UDP are two excellent examples.
