IPv4: Protocols, Implementation, Analysis, Troubleshooting and Support

Why this TCP/IP course?

In just three days, this TCP/IP course provides attendees with the in-depth knowledge and skills that are needed to support IP networks and their users, including advanced diagnosis and troubleshooting of networks using TCP/IP protocols.

• The TCP/IP course also provides relevant introductions to four new and significant areas in IP networking:
  • Voice over IP
  • IPv6
  • IP QoS
  • IP security
  • Mobile IP

Who should attend this TCP/IP course

• Everyone needing a comprehensive coverage of TCP/IP protocols, particularly IT professionals responsible for supporting modern TCP/IP-based networks.

TCP/IP Course Pre-requisites

Delegates should have:

• Worked with a Microsoft Windows operating system, or with UNIX/Linux.
• An appreciation of the OSI seven layer model.
• An understanding of Ethernet and Layer 2 LAN switches.

Course 301: Understanding Telecoms, Datacoms, Mobile, Wireless and IP Networking, is recommended.

Lifetime Post-Course Support

After completing this TCP/IP training course, delegates receive lifetime post-training support from LEVER Technology Group, to help them apply the technologies and skills they have learned with us, to provide career-long support, and to ensure they are better equipped for their future roles in IT and networking.
