Objective:
Compare and contrast the Open Systems Interconnection (OSI) model layers and encapsulation concepts.
Topics Discussed:
- Data encapsulation and decapsulation within the OSI model context
- Ethernet header
- Internet Protocol (IP) header
- Transmission Control Protocol (TCP)/User Datagram Protocol (UDP) headers
- TCP flags
- Payload
- Maximum transmission unit (MTU)
Resources:
- See PowerPoint presentation: 1.1.2 – Encapsulation and Decapsulation.pptx
Assignment:
- Begin reading the 1.1.2 – Encapsulation and Decapsulation.pptx presentation. This lesson will introduce you to what encapsulation and decapsulation is, and how it works with the OSI model we studied yesterday.
- Next, complete the 1.1.2 – Lab – Encapsulation and Decapsulation with Wireshark.pptx Lab posted in the Google Classroom. We will review the concepts presented in the lab to help explain how packets are formed, transmitted, received and decoded.
- To complete this lab, ping a website of your choice while Wireshark is capturing packets, and filter the IP address that you pinged. Post a screenshot of the filtered search to today’s Assignment post in the Google Classroom.
- Please do your best to complete this activity by the end of the day on Wednesday, September 18th.
