The main emphasis of this course is on the organization and management of local area networks (LANs). The course objectives include learning about computer network organization and implementation, obtaining a theoretical understanding of data communication and computer networks, and gaining practical experience in installation, monitoring, and troubleshooting of current LAN systems. Students are introduced to computer communication network design and its operations, and discuss the following topics: Open Systems Interconnection (OSI) communication model; error detection and recovery; local area networks; bridges, routers and gateways; network naming and addressing; and local and remote procedures. On completion of the course, students should be able, in part to design, implement and maintain a typical computer network (LAN).
After successfully completing this course, students should be able to:
- Describe the general principles of data communication. Transmission control protocol/Internet protocol (TCP/IP)
- Describe how computer networks are organized with the concept of layered approach.
- Describe how signals are used to transfer data between nodes and techniques used in data correction during transmission
- network topology and designs
- Implement a simple LAN with hubs, bridges and switches using virtual software.
- Describe how packets on the Internet are delivered.
- Analyze the contents in each data link layer packet, based on the layer concept.
- Design logical sub-address blocks with a given address block.
- Describe the IP multicast and how routing protocols work.
- Understanding VoIP (Voice over IP) under IP telephony networks
Fundamentals of computer networks; communication protocols; the ISO-OSI model; protocol design; internet naming and addressing; Error detection and correction; cyclic redundancy checks (CRC); Internet checksum; data multiplexing; bridges; spanning tree, flooding/multicasting; witching vs routing; switching architectures; IP multicast model; multicast forwarding; link-layer support; Routing protocols: distance vector vs link-state routing; port numbers; service models; flow control vs. congestion control; congestion collapse; Window-based control; rate-based congestion control; switching & signaling; cellular telephone networks.
