📘 WHAT’S INSIDE THIS GUIDE:
✔ Protocol Stack Mechanics: Layered abstractions, PDU headers, encapsulation pipeline, and
MTU fragmentation
✔ Transport Layer Invariants: 3-Way Handshake, 4-Way Teardown, TIME_WAIT state proofs, and
Sliding Window (GBN vs. SR)
✔ TCP Congestion Control Dynamics: AIMD, Slow Start threshold transitions, Fast Retransmit,
and Mathis throughput formula
✔ WORKED STEP-BY-STEP PROBLEM: Variable Length Subnet Masking (VLSM) hand calcula-
tion for a 4-department network
✔ Routing Protocols: Link-State Dijkstra calculations vs. Distance-Vector Bellman-Ford step-by-
step convergence tables
✔ Application & Security: DNS hierarchical recursive lookups, HTTP/1.1 vs. HTTP/2 vs. HTTP/3
(QUIC), and TLS 1.3 handshake flows
✔ 10 Deadly Networking Exam Traps (CIDR host subtraction, TCP byte sequence numbers, ARP
broadcast boundaries)
