Host A sends the information of size 3000 bytes to Host B using TCP protocol. As long as Host B receives each packet in size 1000 bytes, Host B must acknowledge Host A. We assume the header size in each packet is 40 bytes, the starting sequence number used by Host A is 1000, and the window size of the sender side is 3000 bytes. What is the value of SND.NXT when the first packet is sent out, but not acknowledged? 1000 2000 3000 1999 If a host is monitored, and there are seven TCP packets captured: {S1, S2, S3, S4, S5, S6, E1}, where Si represents ith Send packet, and Ej represent jth Echo packet. E1 here acknowledges and echoes all the six Send packets cumulatively. Which of the follow matching can make more sense to represent the RTT of the connection chain? E1 matches with S1 E1 matches with S4 E1 matches with S5 E1 matches with S6
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
Assume now that each packet includes not only payload data, but also a header portion, which contains information like sender and receiver addresses. Furthermore, assume that the maximum payload size of a packet is 1480 bytes, and that the packet header is always 40 bytes long. What is now the maximum packet size (given in bytes)?

Suppose the sequence number field on a TCP packet is 46005. The packet carries 102 bytes of (application-layer) data. The TCP header size on this packet is 20 bytes. (a) What is the sequence number of the last application byte contained in the packet above? (b) What is the value of the acknowledgment number field on the ACK that the receiver generates for the packet above? (c) Do you have sufficient information in this question to determine the value of the sequence number field of the ACK packet that the receiver generates for the packet above? If so, what is the sequence number? If not, why not? (d) If the size of the TCP header were larger (e.g., 24 bytes, due to additional TCP options), would your answers to parts (a)–(c) change? Why or why not?
10. Eight bytes of data, "FE AC 5F DE 9A 8E 1F 39", are transferred using a 802.3 MAC frame. Show the MAC frame in Hex numbers excluding the preamble and start-of-delimiter. The length field specifies the number of bytes in (Data +Pad) fields (not the upper layer protocol indicator). Use a CRC-32 calculator available from the following web site (https://crccalc.com/). Click the "Calc CRC-32" button and read the Result column of the CRC-32 algorithm. MAC addresses are given as: Source: 00 18 8B EB B6 BC Destination: 00 23 72 06 4C 7C
Please solve it correctly. You receive a packet whose data length is 900 bytes, ID is 2398 and the MF flag is set to 0.You received the remaining 12 packets, each of whose total length is 1945 bytes, ID is 2398and the MF flag is set to 1. All of these packets’ header size is 25 bytes.I. Find the packet size of the original datagramII. Find the value of the offset field of the 2nd last packet [First data byte number starts at0]III. How would you identify the last packet in a group of fragmented packets?
Assume the maximum transmission unit (or MTU) of an IP packet on 100 Mbps Ethernet is set at 1500 bytes. Also, assume we are sending our file using IPv6 at the Network layer and UDP at the Transport layer. A typical IPv6 header consists of 40 bytes, a UDP header consists of 8 bytes. Answer the following three questions based on the information provided above. For all answers, enter a decimal integer value without formatting (no commas). 1. How many packets do we have to send in order to transfer a file of 24KB over 100 Mbps Ethernet? packets 2. How many bytes do we have to send at the network layer in order to transfer the above file entirely? bytes 3. How many bytes do we have to send at the data link layer in order to transfer the above file entirely? Assume that the Ethernet header is 14 bytes and the frame checksum is 4 bytes. bytes
Refer to the network figure above, showing two Ethernet Subnets connected through an IP Router, answer the following question 1-5. The devices in each subnet are connected locally to each other through layer two intermediate devices such as Ethernet switch and ethernet hub. For each device in the subnets, both its Internet Protocol (IP )address and its MAC address (also called the Physical address or the Ethernet address are shown. The subnet mask used by all devices is 255.255.255.240 (which is the same as the prefix length “/28”). 1. If Client #1 wants to send a broadcast packet to all the devices on the left subnet (containing client #1, client #2, client #3) what destination IP address should be used? (Mention in both binary and decimal format.) 2. What is the first and last assignable IP address for the left subnet above (containing client #1 and #3)? (Mention in both binary and decimal format.)
13. The following figures plot the timeline for sending TCP segments by host A and TCP ACKS by host B, where “seq #” is the value of the sequence number in the TCP header, and "ACK #” is the value of the acknowledge number in the TCP header. Assume that every segment always includes 500 bytes of data, excluding the TCP header. A seg #: 1000 seq #: 1500 seq #: 2000 seq #: 2500 (1) B ACK #: a ACK #: b ACK #: c ACK #: d A seq #: 1000 seq #: 1500 seq #: 2000 seq #: 2500 (2) B ACK #: r ACK #: s TACK 1) In Figure (1), the second ACK sent out by host B gets lost in the network. a) What are the acknowledge numbers a, b, c, and d? b) Will sender A think the segment with seq#=1500 was lost because it never receives the acknowledgement from B containing ACK# = b? 2) In Figure (2), the second TCP segment from host A to host B gets delayed in the network but later arrives at B. What should be the value for the ACK number r, s and t?
