ECSE-4670 Computer Communication Networks
Catalog Description
A first course in computer communications which introduces the problems,
solutions, and limitations associated with interconnecting computers by
communication networks (LAN or WAN ). The seven layer ISO Open Systems Interconnection
(OSI) reference model serves as a framework for the course with major emphasis
on the physical layer standards, data link protocols, network and transportation
layer protocols. Topics include: modems, baseband and broadband communications,
HDLC, Ethernet and token ring LANs, cell and frame relay networks, bridges,
routers, services of the upper layers (Session, Presentation, Application),
and network security.
Prerequisites: CISH-4010 (knowledge of basic probability and graphs)
Course Objectives
After completing of the course a student will understand:
- Behavior of data signals propagated through a transmission medium,
twisted pair, coaxial cable, optical fiber, and wireless (microwave radio
and infrared);
- Distinction between digital and analog data; and digital and analog
transmission;
- Asynchronous vs synchronous communication;
- Datalink control protocols, the cooperative point-to-point exchange
of data between two devices;
- Error detection, error and flow control;
- Frequency-division multiplexing (FDM) and time-division multiplexing
(TDM);
- Packet-switched networks, network routing and congestion control;
- Basic concepts of frame relay and cell relay networks (ATM);
- Traditional LANs, Ethernet and token ring;
- Bridges, routers and basic principles of internetworking (IP);
- Host to host transport protocol mechanisms (TCP); and
- Network security tools, techniques, and services.
