TCP/IP Networking
Overview
Students will learn the essential knowledge and skills required to configure, support and troubleshoot TCP/IP based networks. TCP/IP is the protocol suite that has become the de facto internetworking protocol used by multiple vendors worldwide. Lectures and hands-on labs are utilized in this course to strengthen and measure a student’s competency of the course objectives.
Who Should Take This Course
Prerequisites

- Calculate and assign the appropriate IP address parameters on a network node
- Explain the role of subnetting, VLSM, and route aggregation
- Explain the need for and differences of IPv6
- Understand how ARP resolves an IP address into a MAC address
- The difference between Unicast, Multicast and Broadcast traffic
- Explain the routing process, routing tables and how routing table entries are populated
- Understand the differences between TCP and UDP
- Describe the functions of common applications FTP, SSH, Telnet, HTTP, SMTP, POP3, IMAPv4, VoIP, and VTC
- Express how ICMP is used in an IP network
- Explain how DHCP and DNS simplify the use of an IP network
- Identify threats to an IP-based network and deploy appropriate security controls
