An IP fragment with 100 bytes of data (not including IP header) is received with the following values: fragment offset = 100 and more flag = 0. The data length (not including IP header) of the original datagram is Impossible to determine from the given information. 900 200 920
Which of the following statements is/are correct?I. The fragmentation is applicable for data in the datagram but not for header.II. Reassembly of the fragments must be performed at the destination because, the intermediatenetworks may have different maximum transmission unit (MTU) sizes.III. In the IP header, the time-to-live (TTL) field is invariable.(A) I and II(B) I and III(C) II and III(D) All are correct
Consider sending a 2400-byte datagram into a link that has an MTU of 700 bytes. Suppose the original datagram is stamped with the identification number 522. Write down the values of the following IP header fields for each of the generated fragments? a. length b. ID c. fragflag d. offset
The network referenced is shown in the picture below: Assume the network uses packet switching and 2 Kilobyte packets. Assume both L1 and L2 each have a propagation delay of 0.1 seconds. We are sending a 100 Kilobyte file. If L1 has infinite bandwidth, and L2 has a bandwidth of 1 Megabit (125 Kilobytes) per second, how long does it take to send the entire file? After the entire file is sent, a single acknowledgment is needed to say the file arrived, how long does the entire process take now (you can assume the ack has negligible size)? If a maximum of 10 packets can be sent per an RTT (this is the equivalent of a fixed window size of 10 packets), how long does it take to send the entire file? What if we start with a congestion window of 1 packet in slow start phase and no slow start threshold, How long to send the entire file now (Hint: This is similar to the previous question but with a variable window rather than fixed)? What if we start in congestion avoidance (linear growth)?
Consider sending a large file of F bits from Host A to Host B. There are three links (and two switches) between A and B, and the links are uncongested (that is, no queuing delays). Host A segments the file into segments of S bits each and adds 80 bits of header to each segment, forming packets of L=80+ S bits. Each link has a transmission rate of R bps. Find the value of S that minimizes the delay of moving the file from Host A to Host B. Disregard propagation delay.
