Course Description

Topics examined in this course include computer networks and the internet, LAN and WAN architectures, and packet switched networks and routing. Students learn about the 7-layer OSI model and internet protocol stack, socket programming and client/server systems, wireless and security. The course includes a laboratory.

Course Learning Objectives

The vision for this course is: What do I, as an application programmer, need to understand about computer networks (including software and hardware both on your computer and elsewhere on the network) in order to write efficient, high-performing programs?

You will have many different opportunities to gain this knowledge through:

  • Homework assignments
  • Hands-on analysis of network data
  • Hands-on laboratory exercises using commercial routers and switches
  • Programming projects where you implement networked applications and tools
  • Student presentations
  • Class lectures, discussions, and reading assignments

After taking this course, you should be able to:

  • be familiar with the terminology in networking, e.g., protocols, RFCs, packets, etc.
  • describe the layered architecture of the Internet
  • differentiate different networking nodes, e.g., switches, routers, firewalls, hosts, etc.
  • understand Ethernet, and its challenges, and how to build wired LANs
  • describe how hubs and switches work
  • understand WiFi, and its challenges
  • describe how to construct an end-to-end communication facility between hosts
  • describe IPv4 service model, packet format, addressing, subnets, etc.
  • understand how physical and logical addresses are translated to each other
  • understand the details of how virtual LANs work
  • understand how errors are handled in networking
  • describe IPv6 service model, packet format, addressing, and differentiate it with IPv4
  • understand the details of connectionless data transport
  • program applications on connectionless data transport service
  • understand the details of reliable data transport
  • understand the details of connection-oriented data transport
  • program applications on connection-oriented data transport service
  • identify services on remote hosts
  • understand how NAT-enabled routers work
  • understand the details about world wide web and HTTP
  • understand the details about electronic mail service
  • understand the details about domain name systems
  • understand the details about dynamic host configuration
  • understand other topics in networking, e.g., virtual private networks, firewalls, software-defined networking, etc.

Attendance Policy

Regular class attendance is strongly encouraged.  Students who miss class meetings are responsible for keeping up with the class.  The course Canvas site will be used to assist in instruction. You are responsible for keeping up with projects, labs, lecture notes, announcements, and other materials that may be posted there.

Grading Policy

Grades for the course are assigned on the scale below:

Grade A A- B+ B B- C+ C C- D+ D F
Points > 93 93-90 < 90-87 < 87-83 < 83-80 < 80-77 < 77-73 < 73-70 < 70-67 < 67-60 60

Recording Policy

All live class presentations and discussions during this course may be recorded. As a student in this class, please note that your participation in live class discussions may therefore also be recorded. By participating in a live class discussion you are giving your consent to this recording. Access to these recordings will be limited to faculty and the students enrolled in the class and to assist enrolled students who cannot attend the live session.

Student Work

Please note that copies of student work may be retained by the instructor to assess how the learning objectives of the course are met. Further, the MOSS (Measure of Software Similarity) system may be used to compare student submissions in an automated fashion.

Honor Code

The Honor Code at the University of the Pacific calls upon each student to exhibit a high degree of maturity, responsibility, and personal integrity. Students are expected to:

  • Act honestly in all matters
  • Actively encourage academic integrity
  • Discourage any form of cheating or dishonesty by others
  • Inform the instructor and appropriate university administrator if she or he has a reasonable and good faith belief and substantial evidence that a violation of the Academic Honesty Policy has occurred.

Violations will be referred to and investigated by the Office of Student Conduct and Community Standards. If a student is found responsible, it will be documented as part of her or his permanent academic record. A student may receive a range of penalties, including failure of an assignment, failure of the course, suspension, or dismissal from the University. The Academic Honesty Policy is located in Tiger Lore and online at https://www.pacific.edu/student-life/student-conduct

Accommodations for Students with Disabilities

If you are a student with a disability who requires accommodations, please contact the Director of the Office of Services for Students with Disabilities (SSD) for information on how to obtain an Accommodations Request Letter.

3-Step Accommodation Process:

  1. Student meets with the SSD Director and provides documentation and completes registration forms.
  2. Student requests accommodation(s) each semester by completing the Request for Accommodations Form.
  3. Student arranges to meet with his/her professors to discuss the accommodation(s) and to sign the Accommodation Request Letter

To ensure timeliness of services, it is preferable that you obtain the accommodation letter(s) from the Office of SSD during the first week of class. After the instructor receives the accommodation letter, please schedule a meeting with the instructor during office hours or some other mutually convenient time to arrange the accommodation(s).

The Office of Services for Students with Disabilities is located in the McCaffrey Center, Rm. 137.
