Chapter 3. Analyzing the TCP Network
TCP is intended to be a host-to-host protocol in common use in multiple networks. In this chapter, we will analyze the TCP protocol in detail with lab exercises and examples.
This chapter covers the following topics:
- Recapping TCP
- TCP connection establishment and clearing
- TCP troubleshooting
- TCP latency issues
- Wireshark TCP sequence analysis
