Defeating TCP congestion-control mechanisms usually requires explicit cooperation of the sender. However, consider the receiving end of a large data transfer using a TCP modified to ACK packets that have not yet arrived. It may do this either because not all of the data is necessary or because data that is lost can be recovered in a separate transfer later. What effect does this receiver behavior have on the congestion control properties of the session? Can you devise a way to modify TCP to avoid the possibility of senders being taken advantage of in this manner?

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.) TCP congestion avoidance.
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?
Please provide explaination. Thank you!
Consider one TCP connection on a path with a bottleneck link with capacity L. We have a file of size F(assume F is a very large file size). If TCP segment size is B bytes, the two-way propagation delay is tp and connection is always in congestion avoidance phase, find the following: A. Maximum window size that TCP can achieve B. Average window size and average throughput in this TCP connection C. Time it will take from connection establishment to reaching the maximum window size.

Consider a TCP connection between Host A and Host B. Suppose that the TCP segments traveling from Host A to Host B have source port number x and destination port number y. What are the source and destination port numbers for the segments traveling from Host B to Host A?
TCP is a connection-oriented protocol. This means that... O a. both of the endpoints communicating over TCP keep information about the state of the connection. O b. a TCP sender can start sending data to the receiver before the three-way handshake takes place. O c. there is a direct physical connection between the two endpoints of a TCP session. O d. both endpoints of a TCP session have to connect to a third party before data can be sent or received.
Is it true or false? Consider TCP congestion control. When the timer at the sender ends, the value of ssthresh is reduced to one-half of its previous value.
Find out the generic format for TCP header options from Request for Comments 793. (a) Outline a strategy that would expand the space available for Options beyond the current limit of 44 bytes. (b) Suggest an extension to TCP allowing the sender of an option a way of specifying what the receiver should do if the option is not understood. List several such receiver actions that might be useful, and try to give an example application of each.
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?
