Course Matierials

  • 3 - Internetworking (slides)

  • Project 2 - HTTP Server

    Specification

    In this assignment your goal is to create your own simple HTTP (web) server. Your server must allow (serve) files and subdirectories from a “document root” folder over a TCP port to HTTP clients (web browsers). Both the document root and TCP port must be configurable via command line parameters or a configuration file. Your server must be able to serve concurrent (simultaneous) requests as well as multiple requests over time.

  • 2 - Direct Link Networks (slides)

  • Project 1 - Number Guessing Server

    Specification

    Your goal is to develop a TCP/IP based server that implements a number guessing game. This assignment is an introduction to TCP/IP socket programming and connecting clients and servers together. You will only be responsible for the server side of things, you can use “telnet” for testing and validation. Additionally you can use telnet, a simple text-based client to interact with your server.

  • COS 460/540 Computer Networks Syllabus

    USM Course Catalog: A description of computer networks organized as a layered architecture based on the OSI Reference Model. Protocols and services of each layer are examined in detail. Specific local area networks, metropolitan area networks, and wide area networks will be considered. Prerequisites: COS 285, COS 251. Cr 3.

    The focus of the course will be on understanding and utilizing the Internet (TCP/IP) protocol stack. Students will write network client and server applications in addition to reading and discussing the theory behind modern data communication networks.

    The class is dual-listed as an undergraduate (COS 460) and graduate course (COS 540); graduate students will have additional reading and must prepare a presentation for the class (see below).
