Question
Need help!
Please donot copy the answers because I have already asked this question 3 times and the last two times the answers were copied from the first time answer which is incorrect.
PLease help me with the correct answer considering the "example scenario".
Consider an example scenario where you want to send some merchandise to your friend living in another city (the kind of friend and the kind of merchandise doesn't matter). You need to answer the following questions:
Example: For instance, we can have local post offices, regional post offices and some global delivery services. Their contracts are based on the amount of merchandise they send and receive.
d) Where the layers would be implemented (end-system, packet switches or both)? Discuss how the intermediate systems would process the parcels from source to destination? Again, make reasonable assumptions.
e) At the application layer, what are the things we can do to our merchandise? Should we use some protocol? Would this protocol be only implemented at the sender side?
f) In reference to the transport layer, we have TCP and UDP on the internet. Relate the basic services provided by them to our example. Which protocol should we use?
g) Explain and relate the concepts of IP addresses, MAC addresses, Sockets, Port numbers and Processes with our example scenario.
h) You need to explain and relate the application architectures, Client Server and the Peer-to-Peer for the merchandise delivery. Make reasonable assumptions where needed.
Explanation / Answer
Answer D
The following are the activities in this case
Person delivery of parcel
Post office counter handling
Ground transfer: loading on trucks
Airport transfer: loading on airplane
Airplane routing from source to destination
Postal person giving it to the receiptant
Application Kayer: people using the postal system ( Details are captured)
Session and presentation: Priority ( Overnite or regular
postal system computes a route and forwards the letters Network
datalink layer: letters carried by planes, trains, automobiles
physical layer: the goods that has yo be tranfrred
Answer E
Application layer is used to process the request.Here in this case it takes data details of Recevier, Sender and what to be sent.It uses HTTP protocol to send information to next level beacuse it is based on request and response
Answer F
TCP has assurance that the goods are reached to the destination. It takes a signature from the receiptant and acknowlwedges that goods are reached
UDP will not have confirmation from the receiptant.But this is very faster
In our case it is good to go with TCP since there is guarantee that goods are reached, It may take time but delivery is confirmed.
Answer G
IP addresses, MAC addresses, Sockets, Port numbers and Processes
1, IP address: Our homE address and address to whom we need to send
2. MAC address:Post office addresses at both the locations
3.Sockets: Vans,planes or trucks
4.port number: zip codes of postal offices to connect
5, Proccess
1. The data is carried in various ways to reach destination.
