Course Description:

TCP/IP is the dominant networking protocol. Currently most TCP/IP networks are using IPv4 and this is the version covered in this course. 

IPv6 is covered in the Introduction to IP v6 course.

The purpose of this course is to provide a comprehensive understanding of all the protocols that make up TCP/IP, how they fit together, and what their strengths and limitations are. With such an understanding students will be in a much better position to tackle/manage network configuration, administration, security and management tasks. 

You can learn key skills …

• Understanding how TCP/IP can run over various link layer protocols (such as ethernet, token ring, ATM, serial links such as ISDN, dialup modem, ADSL,  and Frame Relay)
• Knowledge of static vs. dynamic IP address configuration and related protocols - ARP, ICMP, PING, DHCP)
• Classful addressing
  • subnet masking (fixed and variable length)
  • private IP addresses
  • Network Address Translation
• Appreciation of the differences between distance vector, link state and path vector protocols
• Distinction between connection oriented and connectionless protocols
• Awareness of how important protocols such as FTP, HTTP, DNS and SMTP work

Who Needs to Attend:

The course is aimed at those who already have a basic understanding of networks and datacomms, and who wish to more fully understand TCP/IP, and to fill in any gaps in their existing knowledge. 

The emphasis in this course is to understanding how the various protocols work - not only theoretically, but by examining various protocol analyser traces and SNMP management station displays.

Practical problem situations and network troubleshooting strategies used to resolove such problems are also covered.

Prerequisites:

The course assumes a basic understanding of networks and datacomms.
