- Suppose Alice with a Web-based e-mail account (such as Gmail) sends it 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 movethe message between the two hosts.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.Are the TCP receive buffer and the application buffer on the client exactly the same thing when HTTP streaming is being used? How are they supposed to behave toward one another if they are unable to converse with one another?
- Several bits can be sent over a link between two hosts at the same time. I'd appreciate it if you could give me a plan of all the things that need to be done to finish one package. Is it expected that one delay will last for a certain amount of time and that the length of the other delay will depend on what's going on?Suppose Alan, with a Web-based e-mail account (such as Gmail or Yahoo! Mail), sends a message to Benson, who accesses his mail from his mail server using POP3. Discuss how the message gets from Alan's host to Benson's host. Be sure to list the series of application-layer protocols that are used to move the message between the two hosts.Is the client's application buffer and the TCP receive buffer the same thing when utilizing HTTP streaming? How are they supposed to engage with one another if they are unable to speak with one another?
- What is the HOL blocking issue in HTTP/1.1? How does HTTP/2 attempt to solve it?Assume that Computer A, which is connected through an Ethernet cable to the Switch S1, is just powered on. The user opens a browser and then types a website address to receive the website from the Server (as shown in Figure 1). Write down all the important protocols that come into play by the time the first frame containing HTTP request reaches R1. (Note: Before HTTP frame, other frames have already been sent by other protocol(s).) Write down all the protocols with reference to the TCP Model as follows? Application Layer: Transport Layer: Internet Layer: Link Layer:Assume that Computer A, which is connected through an Ethernet cable to the Switch S1, is just powered on.

(Note: Before http frame, other frames have already been sent by other protocol(s).) Write down all the protocols with reference to the TCP Model as follows. Application Layer: Transport Layer: Internet Layer: Link Layer: [Physical Layer (if needed)]: After writing down the protocols that come into play, briefly write the procedure as to what happens
- In a bit-oriented link-layer protocol, the start and end of a frame are each marked by a flag, which is a sequence of exactly 6 consecutive 1 bits. Bit stuffing is used during the rest of the frame: after sending 5 consecutive 1 bits, a 0 is added. The bits below contain an example frame, with the leftmost bit received first. The content of the frame is a sequence of bytes, sent most significant bit first. Put the values of the first four bytes of the frame content, in order, in the four answer boxes below. You may enter the values in either decimal (e.g. 76, 123) or hexadecimal (e.g. 2a, f7). 00101011111010001111110011100111110000111101111101010110100010010011111101101100100 57−240−123−229In HTTP version 1.0, a server marked the end of a transfer by closing the connection. Explain why, in terms of the TCP layer, this was a problem for servers. Find out how HTTP version 1.1 avoids this. How might a general-purpose request/reply protocol address this?Please do not give solution in image format thanku Suppose two packets arrive to two different input ports of a router at exactly the same time. Also suppose there are no other packets anywhere in the router. Suppose the two packets are to be forwarded to two different output ports. Is it possible to forward the two packets through the switch fabric at the same time when the fabric uses a shared bus? Suppose the two packets are to be forwarded to two different output ports. Is it possible to forward the two packets through the switch fabric at the same time when the fabric uses switching via memory? Suppose the two packets are to be forwarded to two different output ports. Is it possible to forward the two packets through the switch fabric at the same time when the fabric uses a crossbar? Suppose the two packets are to be forwarded to the same output port. Is it possible to forward the two packets through the switch fabric at the same time when the fabric uses a crossbar?
