Chapter 3 - Transport layer. After reading this chapter, the reader should be able to: Understand the position of the transport layer in the internet model; understand the rationale for the existence of the transport layer; understand the concept of application-to-application delivery; understand the duties of the transport layer: packetizing, addressing, connection creation, and reliable delivery. | Chapter 3 Transport Layer Understand the position of the transport layer in the Internet model. Understand the rationale for the existence of the transport layer. Understand the concept of application-to-application delivery. Understand the duties of the transport layer: packetizing, addressing, connection creation, and reliable delivery. After reading this chapter, the reader should be able to: OBJECTIVES Know which application layer program can use UDP and which can use TCP. Distinguish between the two transport-layer protocols used in the Internet: UDP and TCP. APPLICATION-TO- APPLICATION DELIVERY Figure 3-1 Transport layer in the Internet model Figure 3-2 Application-to-application delivery DUTIES Figure 3-3 Duties of the transport layer Figure 3-4 Connection establishment Figure 3-5 Connection termination Connection is closely related to reliability: A connectionless protocol cannot be reliable because the relationship between packets provides reliability.
