TCP is a sliding window protocol. This means. а. there can be more than one segment "in flight" (sent but no ACK has been received) at a time. O b. the TCP retransmission timer slides up as ACKS are received. O c. there can only be one segment outstanding (sent but no ACK has been received) at at time.
In modern packet-switched networks, including the Internet, the source host segments long, application-layer messages (for example, an image or a music file) into smaller packets and sends the packets into the network. The receiver then reassembles the packets back into the original message. We refer to this process as message segmentation. Figure 1.27 illustrates the end-to-end transport of a message with and without message segmentation. Consider a message that is 8. 106 bits long that is to be sent from source to destination in Figure 1.27. Suppose each link in the figure is 2 Mbps. Ignore propagation, queuing, and processing delays. a. Consider sending the message from source to destination without message segmentation. How long does it take to move the message from the source host to the first packet switch? Keeping in mind that each switch uses store-and-forward packet switching, what is the total time to move the message from source host to destination host? b. Now suppose that…
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?
Consider a TCP connection with the following parameters: a) Initial ssthreshold = 8 b) Round Trip Time (RTT) = 10 milliseconds c) Retransmission Timeout period = 40 milliseconds d) Segment size = 2700 bytes The TCP connection was used to transfer 19 data segments, numbered 1 through 19. While sending the segments, data segment 10 was lost the first time it was sent (but arrived at the receiver properly upon being retransmitted). There were no other segment losses apart from the aforementioned. Assume that data segments received out-of-order are buffered at the receiver. What is the average throughput obtained in sending all the data segments (in bytes/sec)? Draw a diagram to show the transmission of the segments in detail.
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.
Is this the right answer or the wrong answer? Assume that the most recent SampleRTT for a TCP connection is one second. The TimeoutInterval setting for the connection must now be set to a value that is greater than one second.
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. TCP sender t=1 T t=2 t=3 t=4+ t=5- t=6+ t=11 t=12 t=13 t=14 t=15 t=16 t=17 t=18 I data segment data segment data segment data segment data segment data segment data segment data segment ACK ACK ACK ACK ACK ACK Ty A A V V htt TCP receiver t=6 t=7 t=8 t=9 t=10 t=11 t=12 t=13 What does the sender do at t=17? You can assume for this question that no timeouts have occurred.
Consider a TCP connection with the following parameters: a) Initial ssthreshold = 4 segmentsb) Round Trip Time (RTT) = 10 millisecondsc) Timeout period = 40 millisecondsd) Segment size = 3900 bytesThe TCP connection was used to transfer 17 data segments. While sendingthe segments, data segment 7 and data segment 15 were lost the first timethey were sent (but arrived at the receiver properly when retransmitted).There were no other segment losses apart from the aforementioned. Assumethat data segments received out-of-order are buffered at the receiver. Whatis the average throughput obtained in sending all the data segments (inbytes/sec) including draw a diagram to show the communication process in detail.
Consider a simple protocol for transferring files over a link. After some initial negotiation, A sends data packets of size 1 KB to B; B then replies with an acknowledgment. A always waits for each ACK before sending the next data packet; this is known as stop-and-wait. Packets that are overdue are presumed lost and are retransmitted. (a) In the absence of any packet losses or duplications, explain why it is not necessary to include any "sequence number" data in the packet headers. (b) Suppose that the link can lose occasional packets, but that packets that do arrive always arrive in the order sent. Is a 2-bit sequence number (that is, N mod 4) enough for A and B to detect and resend any lost packets? Is a 1-bit sequence number enough? (c) Now suppose that the link can deliver out of order and that sometimes a packet can be delivered as much as 1 minute after subsequent packets. How does this change the sequence number requirements?
It is possible for a series of packets to be sent from one host to another over the same connection. Please break down the time it takes for a single package to go from beginning to conclusion. Is it expected that one of the delays would last a certain period of time while the other delay's length will be more malleable?
TCP is a sliding window protocol. This means... а. the TCP retransmission timer slides up as ACKS are received.

Suppose two TCP connections share a path through a router R. The router's queue size is six segments; each connection has a stable congestion window of three segments. No congestion control is used by these connections. A third TCP connection now is attempted, also through R. The third connection does not use congestion control either. Describe a scenario in which, for at least a while, the third connection gets none of the available bandwidth, and the first two connections proceed with 50% each. Does it matter if the third connection uses slow start? How does full congestion avoidance on the part of the first two connections help solve this?
