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...

WHAT IS THE ANWER FOR THE TWO
QUESTIONS
Consider the two 16-bit words (shown in binary) below. Recall that to compute the Internet checksum of a set of 16-bit words, we compute the one's complement sum of the two words. That is, we add the two numbers together, making sure that any carry into the 17th bit of this initial sum is added back into the 1's place of the resulting sum); we then take the one's complement of the...

1. After transmiting a batch of packets, when a timer expires (timeout event happens), a TCP sender retransmits Optional Answers: 1. all packets for which It had not yet received an acknowlegement 2. a single packet: the oldest unacked packet 3. the acknowledgement it has just received 4. The last packet that it had transmitted 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...
