Let's use an example where a packet is being transmitted along a predetermined path from one host to another. The following is a list of the delay's components. Which of these delays is a fixed one, and which one changes with time?
Step by step
Solved in 2 steps
- Think about sending an email or other kind of message over the same route from one host to another at a certain time frame. Below you'll find a breakdown of the delay's many components. Is one of these lags a constant or does it change over time?Let's imagine, for the sake of illustration, that a packet is now being sent from one site to another along a predetermined route. The following is a list of the components that make up the delay: Which of these delays is an ongoing problem, and which of them is sporadic in nature?Please solve it correctly and please provide explanation of your answers. Please answer parts g, h and i. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was corrupted. So the PC immediately sends an acknowledgement segment. Assume that the PC uses Selective Repeat/Reject ARQ. g) The second segment from webserver was corrupted. So the PC…
- For NAT Network Address Translation Scenario: Jenny Bello is a small business owner selling and making customized computer peripherals. She has been finding it difficult to track her sales and inventories, however recently after an expert's advice, she adopted a Point of Sale (PoS) server. So, she can now track her sales and inventories at the store. However, she ran into another issue, the server can only be accessed within the store, because it has been assigned a private IPv4 address, it is not publicly accessible via the Internet. a) Why is not having the PoS server accessible over the Internet a problem for the business? b) What caused this problem? c) Propose a solution for the problem and explain how the solution works.A TCP connection is using a window size of 8,000 bytes and the previousacknowledgment number was 10,001. It receives a segment with acknowledgment number 12,001 and window size advertisement of 7,000 bytes. Draw a diagram to show the situation of the window before and after.Asap
- In a data communication system, several messages that arrive at a node are bundled into a packet before they are transmitted over the network. Assume that the messages arrive at the node according to a Poisson process with rate 30 messages per minute (0.5 per second). Five messages are used to form a packet.What is the mean time until a packet is formed, that is, until five messages arrive at the node?Please solve it correctly and please provide explanation of your answers.

Which of these delays is a fixed one, and which one changes with time?Skype is a well‑known VoIP system used not only for peer‑to‑peer conversations but also for audio and video conferencing involving three or more callers. Assume a video conference with a central server on Skype has N callers, and each caller generates a constant data stream at rate r bps. How many bits per second does the call initiator need to send? How many bits does each of other N‑1 callers need to send?An HTTP client opens a TCP connection using an initial sequence number (ISN) of 14,534 and the ephemeral port number of 59,100. The server opens the connection with an ISN of 21,732. Show the three TCP segments during the connection establishment if the client defines the rwnd of 4000 and the server defines the rwnd of 5000. Ignore the calculation of the checksum field.
