IP Fundamentals
What will you learn?
On completion of this one day course, delegates will be able to;
- Describe the concept of a datagram
- Explain the restrictions of an unreliable and connectionless network and how a reliable connection based service can be provided where necessary
- Describe the relationship of the transmission of data using IP onto the OSI 7-layer model and explain the principles of data encapsulation between the layers
- Identify the Ethernet addresses and frame type from a captured Ethernet packet
- Describe the purpose of the Ethernet frame type
- Explain why Ethernet broadcasts are important and how they are implemented
- Explain the way that IP addresses can be allocated, and the function of sub-net masks
- Suggest where it is appropriate to use private IP addresses
- Describe the key principles of IP routing
- Describe the various fields in an IP packet and suggest which are important
- Describe the principle of the time to live and how it is used to provide route traces across the network
- Explain the fragmentation of packets and the implications
- Describe the way that ARP obtains Ethernet addresses
- Describe how DHCP operates and the relevance of the configuration parameters
- Explain the reasons for the additional protocols TCP, UDP and ICMP and how they are carried over IP
- Identify the details of how ICMP, UDP and TCP are encoded on the network
- Describe how TCP provides error recovery and session control
- Describe the purpose of multicast and how it is implemented over Ethernet
- Explain the basic principals of operation of telnet, http, smtp
- Apply the knowledge gain to monitor a local area network to identify problems
Course Overview
The JANET network and the Internet work solely using the Internet Protocol(IP), as do almost all networks in institutions. This course looks at the Internet Protocol in detail, from the basic principles of operation down to the actual data transmitted, with an emphasis on operation over Ethernet. However it is presented in a way which should not deter those who are not from an over-technical background who should still gain useful information from the course.
The course includes a number of hands-on lab sessions for delegates to work through in small groups, looking at some of the features of the Internet Protocol and examining live packet captures to backup the information provided in the course.
Topics Covered
- History of IP
- Principles of operation
- Ethernet – Frame format, ARP, DHCP, Broadcasts
- IP basics, addressing, network masks, subnets, routing, IP packet format
- ICMP, UDP, TCP – principles of operation and implementation
- Applications – Telnet, HTTP, SMTP, etc
- Troubleshooting
Who should attend?
This technical course is aimed at anyone involved with the operation or specification of an IP based network. It will be particularly useful for those involved in trouble shooting network problems or configuring computers to use the network. The activities are largely based on Microsoft Windows so some knowledge of Windows operation will be useful. The course assumes a basic knowledge of hubs, switches, routers, etc such as is covered on the JANET Training's Basic Networking course.
Timetable/On the Day
The course timetable will be adjusted on the day to allow discussion of areas of particular interest to the audience. The course will therefore run from 10am to 4.30pm. Registration will take place from 09:30 – 10:00.
All our courses are designed to provide a balance between practical activities and information dissemination as we believe people learn when they are engaged within the instructional process. This course includes participant involvement through hands-on activities, discussion, group work and simulations created specifically for the course. All delegates will receive a workbook specifically written for the course.
