2. The following illustration shows a transmission from Host A to Host B using Network Address Translation (NAT). Host A is located inside a Local Area Network (LAN) with an IP address of 192.168.1.2. The LAN is connected to the Wide Area Network (WAN), i.e. the Internet, through a router R1 that conducts NAT. R1 has two interfaces with an internal LAN IP address (192.168.1.1) and and external WAN IP address (127.45.10.35). Host B is located outside the LAN and is a well-known server, e.g., Google's server. Host B has an IP address of 130.160.23.45. Port numbers for the application components running at both hosts are provided in the figure. For a single message M1 being sent from Host A to Host B, please fill in the blanks in the illustration below with the source IP address and Port number at Host A and at the Router R1. Any information not provided may be assumed, however, please state your assumption clearly. Local Area Network (LAN) Host A (Source) IP: 192.168.1.2 Port: 5252 192.168.1.1 R1 Wide Area Network (WAN) Host B (Destination) IP: 130.160.23.45 Port: 8080

A router interconnects a subnet, where all the interfaces of the subnets must have the prefix 164.132.62/24. suppose that the Subnet is required to support up to 60 interfaces, provide a network address that satisfies the above.
3.5-4 TCP sequence numbers and ACKs (2). Suppose that as shown in the figure below, a TCP sender is sending segments with 100 bytes of payload. The TCP sender sends five segments with sequence numbers 100, 200, 300, 400, and 500. Suppose that the segment with sequence number 300 is lost. The TCP receiver will buffer correctly-received but not-yet-in-order segments for later delivery to the application layer (once missing segments are later received).

Assignment 5: Both TCP and UDP are widely used IP transfer layer protocols. For applications requiring reliable transfers, TCP is generally preferred, while applications that value throughput more than reliability are best served using UDP. Most TCP/IP stacks provide both protocols, so the application can use whichever transfer protocol is more appropriate, even changing from one to the other as desired. Rather than rely solely on TCP, the network system developer might want to investigate the trade-offs related to use of UDP. Based upon the analysis list out why Some TCP/IP Applications Use UDP?

1.4-10 Link Utilization (a). Consider the scenario below where 4 TCP senders are connected to 4 receivers. The servers transmit to the receiving hosts at the fastest rate possible (i.e., at the rate at which the bottleneck link between a server and its destination is operating at 100% utilization, and is fairly shared among the connections passing through that link). Server-1 Host-1 Server-2 Rs Rc Server-3 Rs Rc Rs R Rc Host-3 Server-4 Rs Rc Host-4 Host-2 Suppose that R = 1 Gbps and Rc is 300 Mbps and R, is 200 Mbps. Assuming that the servers are sending at their maximum rate possible, enter the link utilizations for the client links (whose rate is Rc) below. Enter your answer as a decimal, of the form 1.00 (if the utilization is 1, or 0.xx if the utilization is less than 1, rounded to the closest xx). The utilization of the client links, whose rate is Rc, is: [A]

1. A protocol uses hierarchical slotted TDM techniques for various levels of networks. For the purpose of this question, assume header/trailer overhead to be zero, use the different DLC frame sizes as given. In this question we consider only DLC frames. At the level of Local Area Networks (LANS) containing each individual computer, the links operate at 10 Mbps and the frames (L-frames) are each 1500 bytes long. The LANs link to Metropolitan Area Networks (MANS) which use 15000 byte M-frames that are made by multiplexing 10 L-frames, one each from 10 different LANs. Every ten of these MANS feed into a Regional Area Network (RAN) that uses 1 Gbps links and uses a R- frame, and ten RANS feed into a Wide Area Network (WAN) using a W-frame, which is 32 times the size of an R-frame. (a) The transmission time of a bit or group of bits is sometimes referred to as their "width" on the line. What is the width of an L-frame on a LAN link? (b) How wide is an L-frame (as embedded inside larger…
