IPv4: Protocols, Implementation, Analysis & Troubleshooting

Course Overview

This unique IP training course has been developed to meet the requirements of IT professionals supporting modern TCP/IP-based networks. This IP course is designed for people who want a truely comprehensive coverage of TCP/IP protocols and the recent developments in IP networking.

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.

Each TCP/IP training course module incorporates extensive hands-on practical sessions, working with TCP/IP on Microsoft Windows operating systems, UNIX and IP routers. Delegates also perform in-depth network protocol analysis, and work with widely-available third-party diagnostic utilities.

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

Audience

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

Prerequisites

Delegates will have worked with a Microsoft Windows operating system, Linux or UNIX, and should have a good understanding of Ethernet, LAN hardware, and an appreciation of the OSI seven layer model.

Course: Introduction to Datacomms and Networking, is recommended.
