It is theoretically feasible for two hosts to communicate with one another by sending packets back and forth over the same connection. Please enumerate all of the components that are responsible for the overall amount of time required to process a single packet, starting to end. Is it to be anticipated that one of the delays will continue for a certain amount of time, while the duration of the other delay will be more unpredictable?
A frame containing http request is sent from Computer (A) [in whichever subnet it is now, make sure to show it in your figure], to the access point it is associated with. Draw the address fields (1, 2, and 3) of the frame travelling from Computer A to AP and the source and destination addresses of the frame travelling from AP to R1. The MAC addresses of AP1, AP2, and AP3 are M1, M2, and M3 respectively, and the Router R1’s MAC address connected to this Switch/AP is MRA. IP address values are already given, and the port addresses could also be used as given. The Router’s MAC address facing WAN side is MRW.
Consider a network with a data rate of 10 Mbps. Messages sent on this network have a maximum size of 1000 bits, including a 16-bit control field. What is the number of messages required to send a file F of 4 Mbits from one station to another? Assuming that a station cannot send a new message until it receives an acknowledgment of the successful reception of the previously sent message. The acknowledgment takes the form of a 16-bit message. A timer is set to a duration T after the sending of each message. If time T expires before receiving an acknowledgment, the sending station resends the same message. The distance between the two farthest stations in the network is 1 km. The signal propagation speed is v = 200,000 km/s. What is the minimum value of T? (You ignore the queuing time and the processing time and use only the propagation time and the transmission 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?
(a) Suppose a server S and client C are connected over the Internet. The one-way prop- agation delay from S to C is 50 ms. The maximum throughput between S and C is R = 200 Mbps. A browser on client C makes an HTTP request for a webpage on server S. The base HTML file is of size 500 KB and it references five objects, each of size 5 MB. Find the total response time for the client to receive the entire webpage using nonpersistent HTTP with up to two parallel connections. Assume that when two par- allel connections are active, the throughput for each connection is 40% of the maximum throughput R. (b) Suppose an application running on host ece.gmu.edu needs to resolve the domain name cs.vtech.edu. Draw a diagram (with labels) showing the sequence of queries/responses in a recursive DNS query to find the answer in a scenario where all levels of the DNS hierarchy are involved.
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 single link has the capacity to transmit multiple packets simultaneously between two hosts. Kindly provide a schedule delineating the various activities that are required to be accomplished in order to successfully execute a single consignment. Is it anticipated that one of the delays would exhibit a constant duration, whereas the duration of the other delay may be adjusted as required?
A file of size 20 KiloBytes is transmitted to a destination over a 10 Megabit/s network link (1 Mega = 10^6, 1 Kilo = 10^3, 1 byte = 8 bits). The propagation delay to the destination is 40 milliseconds (1 milli = 10^−3). Assume the queueing delay encountered by packets of the file is negligible. What is the total delay (in milliseconds) for the file to get to its destination?
4) Host A and B are communicating over a TCP connection, and Host B has already received from A all bytes up through byte 130. Suppose Host A then sends two segments to Host B back-to-back. The first and second segments contain 80 and 40 bytes of data, respectively. In the first segment, the sequence number is 131, the source port number is 301, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A. a. In the second segment sent from Host A to B, what are the sequence number, source port number, and destination port number? b. If the first segment arrives before the second segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number, the source port number, and the destination port number? c. If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number?
TCP congestion control example. Consider the figure below, where a TCP sender sends 8 TCP segments at t = 1, 2, 3, 4, 5, 6, 7, 8. Suppose the initial value of the sequence number is 0 and every segment sent to the receiver each contains 100 bytes. The delay between the sender and receiver is 5 time units, and so the first segment arrives at the receiver at t = 6. The ACKs sent by the receiver at t = 6, 7, 8, 10, 11, 12 are shown. The TCP segments (if any) sent by the sender at t = 11, 13, 15, 16, 17, 18 are not shown. The segment sent at t=4 is lost, as is the ACK segment sent at t=7.

You can assume for this question that no timeouts have occurred.

To ensure the quality of service, especially for multiple applications, regulating the rate at which packets are sent to the network is an important strategy. The leaky bucket is just one of such mechanisms. A flow of packets is said to conform to the leaky bucket specification (r, b), where r is the average rate and b is the burst rate, if the number of packets arriving at the leaky bucket is less than r*t + b in every time interval of t. What is the implication of that? What will happen if the number of packets arriving at the leaky bucket is equal to or greater than r*t + b?
