1. Module 1: Reviewing the Suite of TCP/IP Protocols

2. Overview Overview of the OSI Model Overview of the TCP/IP Protocol Suite Viewing Frames Using Network Monitor

3. Lesson: Overview of the OSI Model What Is the OSI Model? The Layers of the OSI Model

4. What Is the OSI Model? In the OSI model: Each layer has a defined networking function Each layer communicates with the layer above and below it Layer seven provides services for programs to gain access to the network Layers one and two define the network’s physical media and related tasks Application Presentation Session Transport Network Data-Link Physical 7 7 3 3 4 4 5 5 6 6 2 2 1 1

5. Multimedia: The Layers of the OSI Model Application Presentation Session Transport Network Data-Link Physical All People Seem To Need Data Processing

6. Practice: Putting the Layers of the OSI Model in Order In this practice, you will put the layers of the OSI model in their correct order

7. Lesson: Overview of the TCP/IP Protocol Suite Why Do I Need to Know About TCP/IP? What Is the Architecture of the TCP/IP Protocol Suite? How Does the TCP/IP Model Relate to the OSI Model? How an IP Packet Moves Through the Suite of TCP/IP Protocols

8. Multimedia: Why Do I Need to Know About TCP/IP? You need to understand the addressing scheme of your network to correctly configure client computers to access it using TCP/IP You need to know the locations of the windows where you enter the TCP/IP information You must be able to find the TCP/IP information that you use to configure client computers

9. What Is the Architecture of the TCP/IP Protocol Suite? Transport Internet Link Application Ethernet Frame Relay Token Ring ATM HTTP FTP SMTP DNS RIP SNMP TCP/IP Protocol Suite TCP UDP IP ARP IGMP ICMP

10. TCP/IP Protocol Suite TCP/IP OSI How Does the TCP/IP Model Relate to the OSI Model? TCP UDP ARP IGMP ICMP IP Ethernet Frame Relay Token Ring ATM Application Transport Link HTTP FTP SMTP DNS RIP SNMP Application Transport Network Data-Link Presentation Session Physical Internet

11. Multimedia: How an IP Packet Moves Through the Suite of TCP/IP Protocols The Four Layers of the TCP/IP Protocol Suite: Application Transport Internet Link

12. Practice: Associating the Protocols and Layers of the TCP/IP Model In this practice, you will associate the protocols and layers of the TCP/IP model

13. Lesson: Viewing Frames Using Network Monitor What Is Ping? What Is Network Monitor? How to Capture Frames How to Filter for Select Frames Examining Captured Network Traffic

14. Server Client Computer You can run Ping from a client computer to test the connection to any host, such as a printer or a server: The server sends an Echo Reply back to the client computer The client computer sends an Echo Request to the server You check the details of the Echo Reply to determine the quality of the connection Pinging LONDON (192.168.2.10) with 32 bytes of data: Reply from 192.168.2.10: bytes=32 time<10ms TTL=128 Reply from 192.168.2.10: bytes=32 time<10ms TTL=128 Ping statistics for 192.168.2.10: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = Oms, Maximum = Oms, Average = Oms What Is Ping?

15. What Is Network Monitor? Network Monitor: Captures a sample of network traffic Uses filters to select specific packets Decodes the packets in the language of the individual protocols Compiles network statistics 1 1 2 2 4 4 3 3

16. Practice: Installing Network Monitor In this practice, you will install Network Monitor

17. Your instructor will demonstrate how to use Network Monitor to capture frames How to Capture Frames

18. Practice: Capturing Frames In this practice, you will use Network Monitor to capture frames

19. Your instructor will demonstrate how to filter for select frames How to Filter for Select Frames

20. Examining Captured Network Traffic

21. Practice: Examining Packets In this practice, you will: Examine ICMP Packets Examine ARP Packets
