This course has been replaced with COMP 3521. his hands-on course covers the theory, design and implementation of large scale and enterprise size networks. The functions and limitations of network layer protocols and design issues of the TCP/IP Network Layer protocol are discussed. This course focuses on the TCP/IP protocol; students learn how computers exchange data over the Internet and how network communication relates to network configuration and administration. Topics include: Selection criteria required to create, expand or improve a network, implementation of the TCP/IP protocol suite within a network and surrounding routing issues. Students will work in groups to study the theory and design of router operation, network performance, scalability and basic router security issues. Upon successful completion, participants will have an in-depth knowledge of TCP/IP, network masking; and how to plan and build a routed network. This course consists of one face to face meeting each week, group work, a significant online component and home work.
