23-1 PROCESS-TO-PROCESS DELIVERY

The transport layer is responsible for process-to-

process delivery—the delivery of a packet, part of a

message, from one process to another. Two processes

communicate in a client/server relationship, as we will

see later.

23-2^ USER DATAGRAM PROTOCOL (UDP)^ The^ User^ Datagram 23.

Protocol^ (UDP)^ is called^ a connectionless, unreliable transport protocol. It doesnot add anything to the services of IP except to provideprocess-to-process communication instead of host-to-host communication.^ Topics discussed in this section: Well-Known Ports for UDPUser DatagramChecksumUDP OperationUse of UDP

23.

Note^ UDP length= IP length – IP header’s length

Figure 23.11 shows the checksum calculation for a verysmall user datagram with only 7 bytes of data. Becausethe number of bytes of data is odd, padding is added forchecksum calculation. The pseudoheader as well as thepadding^ will^ be^ dropped 23.
