UDP and TCP Sessions
At the transport layer of the TCP/IP model you find the User Datagram Protocol. When fast connectionless transport is desired then UDP is the protocol to use. In this course youll learn about the features associated with connectionless protocols. Youll explore the header fields of UPD the functions and ranges of port numbers and the port numbers that are used with UDP. Youll also learn what a socket is and how it is used with TCP/IP. When reliability is necessary for network communications the Transmission Control Protocol is the protocol of choice. In this course youll also learn characteristics of connection-oriented protocols and TCP as well as the names sizes and functions of each TCP header field. Youll explore the importance of eight session flags in the TCP header and how the window size field and maximum segment size options are used to provide flow control. Also youll explore the TCP options and their uses along with the TCP connection and termination process. Finally youll learn about the use of sequence and acknowledgment numbers in providing reliable transport and the methods by which TCP manages network congestion.
