CS341
Introduction to Computer Networks
2022 Spring, KAIST

Overview

The goal of this course is to provide students with sound understanding of fundamental concepts and problems in networking and hands-on experiences in network programming. Resources for programming assignments will include Berkeley socket programming and TCP protocol implementation on KENS.

Description

There will be 4 programming projects: 1 on socket programming, 2 on KENS and 1 on routing. We will post details according to the published schedule. For each project we will hold a tutorial session during the lab time slot.

For 3 KENS programming projects, students have to build up their own TCP implementation on top of KENS (KAIST Educational Network Simulator) framework. We provide a minimal user-level function interface that interacts with user applications and an emulated IP layer which performs static routing. The underlying emulator can simulate both reliable and unreliable link states with configurable and reproducible packet losses and reordering. Your task is to implement the TCP stack API.

For the projects, students will work in a team of two.

  • Project 1: Socket programming
  • Project 2: KENS part I, II
  • Project 3: KENS part III
  • Project 4: Routing
