TCP/IP is the globally accepted group of protocols at the core of the Internet and organizational intranets. A solid understanding of each of these protocols and how they work will give you the ability to deploy the most effective network for your organization in three key areas:

  • Efficiency: You will be able to run a more efficient network through proper implementation of subnetting and understanding how different protocols and applications impact network performance.
  • Dependability: You will reduce downtime in the event of a network failure as you will be better equipped to quickly identify and resolve problems as they occur. You will also be able to solve problems in-house rather than incurring the extra costs and time required to hire a consultant.
  • Future growth: Proper planning will ensure that your network can accommodate growth, including the implementation of more robust network technologies, such as IPv6.

In this course, you will gain the essential knowledge and skills required to set up, configure, support, and troubleshoot your TCP/IP-based network. Our expert instructors and extensive hands-on labs will prepare you to face and overcome the challenges of today's complex networks. This course—the longest running of its kind in the industry—also prepares you for more specialized courses in network security, wireless integration, and Voice over IP (VoIP) as well as for product-specific training such as Cisco, Avaya, and Microsoft.

Learning Objectives

  • Describe the essential elements of the TCP/IP protocol suite
  • Explain the functions of various devices in a TCP/IP network
  • Subnet an IP network using variable-length subnet masking (VLSM), calculating appropriate subnet values to improve network efficiency
  • Describe different TCP/IP protocols—ARP, IP, ICMP, TCP, UDP, and so forth—including their functions and relationships
  • Examine IP routing and the protocols that support it, such as RIP, EIGRP, OSPF, and BGP
  • Explain how applications like FTP, HTTP, Telnet, and others work in a TCP/IP network
  • Analyze UDP and TCP application traffic to identify normal versus abnormal sessions
  • Automate address assignment and name resolution using DHCP and DNS
  • Analyze multicasting and Voice over IP (VoIP) traffic to determine how these protocols affect network performance
  • Troubleshoot problems at each layer of a TCP/IP network using a variety of tools, including a protocol analyzer, traceroute, ping, and DNS and ARP cache manipulation
  • Analyze ICMP variation reports to determine the cause of a network failure
  • Explore network security protocols, including PPTP, L2TP, IPSec, SSL, TLS, and SSH
  • Analyze network traffic to determine security risks
  • Explore the functions of IPv6 and its related protocols
