Overview

Computer Networks at FAST-NUCES Islamabad. The repository has 16 weeks of lecture slides, 15 labs with my C socket programs and Packet Tracer files, three assignments, the CNET project, sessional exams, quizzes, the Kurose and Ross textbook and my study notes.

Unit 1

Application layer

Network edge and core, delay and throughput, HTTP, DNS, email, P2P and sockets.

Unit 2

Transport layer

UDP, checksums, reliable data transfer, Go-Back-N, Selective Repeat, TCP and congestion control.

Unit 3

Network layer

IP addressing, subnetting and VLSM, DHCP, NAT, IPv6, routing algorithms, OSPF and BGP.

Unit 4

Link layer and labs

Ethernet, ARP, VLANs and 15 labs: C socket programming, Packet Tracer routing, Wireshark.

Lectures & Labs
