Below are the two questions, so make sure to answer each part carefully: Why does TCP implement congestion control if it already has flow control to manage the sender's window? Consider our recent reading [Chiu+89] Analysis of the Increase and Decrease algorithms for congestion avoidance in computer networks. How does this article showcases that TCP is fair?
Please help me identify the event and its location in the TCP Reno operation graph shown below. Additionally, please help me explain how we can identify this event based on the changes in the congestion window size. a.) A segment loss event due to a triple duplicate acknowledgment.
Consider the evolution of TCP’s congestion window shown in the figure below and answer the questions. a. Which version of the TCP is running? Provide an explanation of how you have obtained your answer.b. How many losses have been detected during the first 30 transmission rounds? When are these losses detected? Are these losses due to timeout or triple duplicate ACK? Explain.c. What is the value of ssthresh at transmission round 1 and at transmission round 17? How did you find these numbers? Explain.d. How many segments have been transmitted in the first 4 transmission rounds? Show your work.e. At which transmission round segment 70 has been transmitted? Show your work.
Assume that a bottleneck connection with a rate of R bps carries two TCP connections. In both cases, there is a big file that must be downloaded (in the same direction over the bottleneck link). The files are all transmitted at the same time How much data will TCP be able to transmit each connection?
The following event is shown to occur in the figure below illustrating the operation of TCP Reno. For the following prompt, clearly state where it occurs and how we can identify where this event occurs based on the shape of the graph or changes to the congestion window size. a.) A segment loss event due to a timeout.
We discussed increasing the timeout interval once a timeout occurred. This strategy is used to control traffic congestion. Why, in addition to the doubling-timeoutinterval approach, does TCP require a window-based congestion-control method?
Consider the following plot below of TCP window size as a function of time. Assuming TCP Reno is the protocol experiencing the behaviour shown above, answer the following questions. In all cases, you should provide a short discussion justifying your answer. d. After the 22nd transmission round, is segment loss detected by a triple duplicate ACK or by a timeout?e. What is the initial value of Threshold at the first transmission round?f. What is the value of threshold at the 18th transmission round?g. What is the value of threshold at the 24th transmission round?h. During what transmission round is the 70th segment sent?i. Assuming a packet lost is detected after the 26th round by the receipt of a triple duplicate ACK, what will be the values of the congestion-window size and of Threshold?
Describe the TCP congestion control mechanism in further detail.
The integrity of all parties - essentially all of the endpoint operating systems - is required for TCP to function properly. Is it feasible to cheat in TCP, and if so, how can one instance gain from doing so - in comparison to other endpoints?
TCP needs openness from all parties, including most endpoint operating systems. If TCP can be cheated, how can one instance gain an advantage over others?
QUESTION 67 Explain what happen in the following scenario in TCP A sends the first segment to B (successfully delivered) A sends the second segment to B (successfully delivered) B sends the ACK for the first segment (dropped) B sends the ACK for the second segment (successfully delivered)
Clarify the TCP congestion management mechanism and describe its operation.
