TCP is a higher layer protocol that provides in-sequence, connection-oriented, reliable delivery of byte stream between internet applications. In-sequence deliver is possible because each byte has a sequence number, connection-oriented-ness means the two TCP entities first exchange a hand shake before exchanging data and reliable means: a. there is the ability to recover from errors, e. g. via retransmission. b. it has in-built security. c. it uses IP for actual transmission. d. it uses reliable routers.

Install and use wireshark program ( send back screen shots and other vital information) case project 3-2: decode a tcp segment in a wireshark capture in this chapter, you walked through tcp segment to interpret the data included in its header. in this project, you use wireshark to capture your own http messafes, examine the tcp headers, and practice interpreting the data you'll find there. 1. open wireshark and snap the window to one side of your screen. open a browser and snap that window to the other side of your screen so you can see both windows.
