e) Suppose that A datagram of 3,500 bytes arrives at a router and must beforwarded to a link with an MTU of 1,300 bytes. Assume IP header of 20 bytes.Fragment the datagram, and specify the flag, and offset fields of all fragments.

Fragmentation is done at the network layer , so that data link layer will only do the framing,…

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)?
Consider transferring an enormous file of L bytes from Host A to Host B. Assume an MSS of 536 bytes. a. What is the maximum value of L such that TCP sequence numbers are not exhausted? Recall that the TCP sequence number field has 4 bytes. b. For the L you obtain in (a), find how long it takes to transmit the file. Assume that a total of 66 bytes of transport, network, and data-link header are added to each segment before the resulting packet is sent out over a 155 Mbps link. Ignore flow control and congestion control so A can pump out the segments back to back and continuously.
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
السؤال 2 Consider sending a 3500 byte datagram into a link that has an MTU of 1400 bytes. Suppose the original datagram is stamped with the identification number 333.a) How many fragments are generated? b) What are the values of the various fields, related to fragmentation, in each generated IP fragment?
22. A datagram subnet allows routers to drop packets whenever they need to. The probability of a router discarding a packet is p. Consider the case of a source host connected to the source router, which is connected to the destination router, and then to the destination host. If either of the routers discards a packet, the source host eventually times out and tries again. If both host-router and router-router lines are counted as hops, what is the mean number of a. (a) hops a packet makes per transmission? b. (b) transmissions a packet makes? (c) hops required per received packet?
