Answer #1

1. Answer : A
Reason:
After transmitting a batch of packets,when a timer expires(timeout event happens),a TCP sender retransmits all packets for which it had not yet received an acknowledgement

2. With TCP's cumulative acknowledgements,the loss of a packet carrying ACK#N can be "mitigated" by a higher order ACK being received.No retransmissions will be necessary in this case - True

    Consider a simplified actual TCP senderreceiver, described as follows: .Upon a loss (timeout or triple-duplicate ACKs), the sender o transmits the oldest unACKed packet (whose sequence number Base) o restarts the timer Upon receiving an ACK with a Sequence #y > Base. o it considers all packets with sequence numbers s y as ACKed (cumulative ACK) o Sets Base to the sequence number of the packet immediately after the packet whose sequence number is y o Restarts the timer ....

    TCP at Packet Level In a TCP packet level data transfer, sender and receiver both have a window that can hold 4 packets. Sender has 5 packets to send numbered 0-4. ACK 2 is lost and PKT 3 is lost too. (Remember in TCP the ACK number is one greater than the number of the last packet received in order and that ACKs are cumulative) There are no other errors or losses in either direction. Draw a timeline diagram that...

    1. For TCP end-to-end flow control, suppose the capacity of the receiver buffer is 10 packets. Suppose the packets that are being queued in the receiver buffer are packets 4, 5, 6, 7, 8, 10, 11. What is the advertised window size the receiver sent to the sender? Suppose packet 12 is the last packet sent by the sender. What’s the effective window size at the sender? Can the sender send out packet 13 at this moment? How about packet...

    (1) Assume that a station X wants to send 15 packets of data to station Y using TCP Tahoe. Assuming that: 1) The size of each packet sent is 1000 Bytes (ignore all the headers from layers below). 2) Station X chooses 43 as an initial sequence number. 3) Station Y chooses 2 as an initial sequence number. 4) The data of the first packet is included in the final packet of the handshake process. 5) The sender window size...
