EE284: Introduction to Computer Networks Autumn 2010, Professor Fouad Tobagi About the Course Course Description Structure and components of computer networks; functions and services; packet switching; layered architectures; ISO's Open Systems Interconnections (OSI) reference model; physical layer; data link layer; error checking; window flow control; media access control protocols used in local area networks (Ethernet, Token Ring, FDDI) and satellite networks; network layer (datagram service, virtual circuit service, routing, congestion control, IP); transport layer (UDP, TCP); session layer; applications. Prerequisites Undergraduate education in Electrical Engineering or Computer Science. Goal of this course The goal of this course is to introduce the basic concepts and principles underlying packet-based networks. In addition, examples of standard technologies and protocols are given to illustrate the concepts. As a one-quarter introduction to computer networks, the course cannot cover all existing network technologies and protocols. More detailed coverage of network protocols and standards is provided in EE384A, for which this course is a prerequisite. Aspects pertaining to multimedia networking and communications are covered in EE384B. Aspects pertaining to wireless LANs are covered in EE384C. The course is general and introductory in nature, rather than emphasizing on a specific aspect of networking such as protocol design, performance evaluation, or software implementation. Topics Covered Introduction: Circuit Switching & Packet Switching, Structure of Computer Networks, Types of Computer Networks. Layered Protocol Architecture, OSI Reference Model, and the Internet Architecture. The Physical Layer: Theoretical Basis for Data Communications, Signaling and Modulation, Multiplexing, Transmission Media, Physical Interfaces and Protocols. The Data Link Layer: Error Control, Cyclic Redundancy Check, The Sliding Window Flow Control Mechanism, Performance Considerations, Bit-oriented Data Link Control Protocols (HDLC). The Media Access Control Protocols: ALOHA, Reservation Aloha, CSMA/CD (Ethernet), Token Passing Schemes. MAC Layer Bridging and Spanning Tree Protocol. The Network Layer: Addressing, Services (Datagram, Virtual Circuit), Routing Algorithms (Bellman Ford, Dijkstra), Congestion Control, the Internet Protocol (IP). The Transport Layer: UDP, TCP, TCP Congestion Control. The Application Layer: FTP.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
