The transport layer is where sessions are established and data packets are exchanged between hosts. Two core protocols are found at this layer:

 Transmission Control Protocol (TCP): Provides reliable connection-oriented transmission between two hosts. TCP establishes a session between hosts, and then ensures delivery of packets between the hosts.

 User Datagram Protocol (UDP): Provides connectionless, unreliable, one-to-one or one-to-many delivery.
