Course Overview

The NCTI Internetworking with TCP/IP course is the technician’s definitive guide to the logical engine that runs the global internet. While cables carry the signal, TCP/IP manages the conversation.

Geared toward network professionals, this course peels back the layers of the OSI Model to reveal how data actually moves. Students will master the math of IP Addressing and Subnetting, enabling efficient network design. The curriculum covers the full protocol suite—from HTTP, FTP, and DNS to advanced routing protocols like OSPF and EIGRP. Finally, students will learn to command the command line, using utilities like ping, tracert, and netstat to troubleshoot connectivity issues like a pro.

Who Should Attend:

  • Network Technicians
  • Broadband Engineers
  • IT Support Specialists
  • Technicians preparing for SCTE BTCS Certification

What You Will Learn

Upon completion, students will be able to design subnets, choose the correct routing protocols for a network, and isolate communication failures using standard TCP/IP utilities.

Core Competencies:

  • Protocol Architecture: Map TCP/IP layers to the OSI Model and explain the function of protocols like TCP, UDP, ARP, and ICMP.
  • Subnetting Mastery: Perform number conversions (Binary/Decimal) to design subnets, utilizing Variable-Length Subnet Masks (VLSM) and Classless Inter-Domain Routing (CIDR) for efficiency.
  • Routing Protocols: Compare and select routing protocols based on network size, including RIP, IGRP, EIGRP, and OSPF.
  • Support Services: Explain the critical roles of DNS (Domain Name System), DHCP (Dynamic Host Configuration Protocol), and NAT (Network Address Translation).
  • Application Layer: Implement services for email (SMTP), file transfer (FTP/TFTP), and network management (SNMP).
  • Troubleshooting: Use command-line utilities (ipconfig, ping, tracert, pathping) to isolate faults in the network stack.

Certification and Benefits

Master the Logic of the Network

Understanding TCP/IP is the dividing line between a parts-swapper and a true network engineer.

Additional Benefits:

  • SCTE Prep: Excellent preparation for the SCTE Broadband Telecom Center Specialist (BTCS) certification.
  • Industry Recognition: Receive the NCTI Certificate of Graduation.
  • Future Proofing: Includes training on IPv6, ensuring readiness for next-generation addressing.
