Suppose Alice, with a Web-based e-mail account (such as Hotmail or Gmail), sends a message to Bob, who accesses his mail from his mail server using POP3. Discuss how the message gets from Alice’s host to Bob’s host. Be sure to list the series of application-layer protocols that are used to move the message between the two hosts.
It's a good idea to weigh the advantages and disadvantages of connectionless protocols over connection-based protocols, and vice versa.
Consider an HTTP client that wants to retrieve a Web document at a given URL. The IP address of the HTTP server is initially unknown. What transport and application-layer protocols besides HTTP are needed in this scenario?
One helpful exercise is to weigh the merits of connection-based versus connectionless protocols against one another.
Suppose that web server A sends a hypertext document to a web browser in machine B. Describe briefly what happens at each protocol layer. What does encapsulation mean in the context of network protocols?
Let's imagine that a computer on the Internet transmits a packet to another computer at the network layer. The logical destination address of the packet has encountered an issue. What address should I use for the package? How will the original computer know when this happens?
Suppose three hosts inside a private network with adress 172.18.3.1 , 172.18.3.2 and 4M172.18.3.3 need to access the HTTP server on external host 25.8.3.2 . Draw a Fivecolumn Translation table and explain its working.
Suppose the network layer provides the following service. The network layer in the sourcehost accepts a segment of maximum size 1,200 bytes and a destination host address from thetransport layer. The network layer then guarantees to deliver the segment to the transport layerat the destination host. Suppose many network application processes can be running at thedestination host In your protocols, does the transport layer “have to do anything” in the core of the computer network?
please answer with proper explanation and step by step solution. Question: Consider a fictional six-layer protocol hierarchy where layer 1 is the lowest layer, and layer 6 is the highest layer. Therefore, an application sends a message M by passing it to layer 6. All the even-numbered layers attach a trailer Ti (i = 2, 4, 6) to their payload, and all the odd-numbered layers attach a header Hi (i = 1, 3, 5) to their payload. Draw the headers, trailers, and original message M in the order they are sent out.
Comparing connectionless protocols to connection-based protocols, as well as connection-based protocols to connectionless protocols, should be subjected to a cost-benefit analysis.
