Packet Analyzer (part 3) – Sequence in Acknowledgement Numbers in TCP

Sequence in Acknowledgement Numbers in TCP

This lesson discusses sequence numbers in TCP. These numbers work together to establish and determine where you’re at in a specific conversation and are the thing that make TCP such a powerful communication protocol. Sequence and acknowledgement numbers will increment in a predictable and structured manner throughout a conversation and will change relative to how much traffic is happening and how many packets are being changed. They are important because they are very helpful in error checking.
