You live in Omaha, and you are a secret agent. You need to send a three page letter to another secret agent in Blair. You decide to send each page separately because of the highly secret nature of the message. And, you decide to encrypt the message. You send the three pages as registered mail, which requires receipts from the recipient. Describe any similarities between each OSI layer and the secret letter being sent to your fellow agent. A hint for several of the layers: Think about the address on an envelope. What part(s) are similar to the idea of a data frame? What parts are similar to the idea of an IP address?
Solution
The seven OSI layers are defines as follows (Feig)1 :
7. Application: Provides different services to the application
6. Presentation: Converts the information
5. Session: Handles problems which are not communication issues
4. Transport: Provides end to end communication control
3. Network: Routes the information in the network
2. Data Link: Provides error control
1. Physical: Connects the entity to the transmission media
Using above layers comparing each of them with secret letter being sent to our fellow agent.
