- strictly....Do not copy anything from anywhere. i'll give downvotes thenConsider 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 give me correct solution.
- b. Suppose that you are hired by a local company to set up a router that both serves as the network's bidirectional firewall and also NATS hosts in the corporate network. The corporate network consists of about 100,000 machines that simultaneously access the Internet using port-based NAT. What problem could arise if the corporate network only has a single public IP address?Consider a datagram network in which a packet travels through two switches S1 and S2 from source to destination. Packet experiences wait at each switch before it is forwarded. Transmission time, propagation time and wait time at each node is 3 ms, 1.5 ms, and 0.25 ms respectively. Find the total delay.Given that you are to transfer a total datagram of size 28939 bytes over a network that has an MTU of 3038 bytes. The given header size is 38 bytes. (a) Calculate the total number of packets required to send this data. (b) What is the data size of the last packet? (c) What would be the header size of the 8th packet and the offset value of the 4th packet?
- In packet switching: A. Dissembling and re-assembling of data is not required. B. Every chunk of data may select a different route. C. The bandwidth will be allocated for a route which is defined by the router algorithm. D. Every chunk of data have to select a different route. E. None is true. 18-a. Suppose we send into the Internet two IP datagrams, each carrying a different UDP segment. The first datagram has source IP address A1, destination IP address B, source port P1, and destination port T. The second datagram has source IP address A2, destination IP address B, source port P2, and destination port T. Suppose that A1 is different from A2 and that P1 is different from P2. Assuming that both datagrams reach their final destination, will the two UDP datagrams be received by the same socket? Why or why not? b. Suppose Alice, Bob, and Claire want to have an audio conference call using SIP and RTP. For Alice to send and receive RTP packets to and from Bob and Claire, is only one UDP socket sufficient (in addition to the socket needed for the SIP messages)? If yes, then how does Alice's SIP client distinguish between the RTP packets received from Bob and Claire?Imagine for a moment that the desktop of your computer is completely covered with FIN WAIT 1 TCP connections, and that you have a large number of these connections. Is there a certain outcome that is more likely to take place than the others? Who precisely is to blame for this situation?

How "long" (in meters) is one bit on link 1?Computer A is sending a 10 MByte long file to Computer B via packet-switching over two consecutive 100 Mbps links of 2000 km length each.Assume that the signal propagation speed on both links is 2 x 108 m/s.Furthermore, assume that the maximum length of a packet is 1480 bytes and that Computer A fills each packet to the max, if possible. How many bytes will be contained in the last packet?
