Consider the home network setup in Figure 3. Suppose each host of the 3 hosts has two ongoing TCP connections, all to port 80 at host 118.1.40.86. Provide the six corresponding entries in the NAT translation table 10.0.0.1 10.10.10.1 Internet 10.99.10.1 118.1.40.86 10.74.128.34 134.32.12.55 Figure 3: NATing at home router

Consider a TCP segment originating on a host running a Google Chrome Browser destined for the TU Dublin Webserver: (1) Separately identify how the port numbers are assigned for the client and server applications and, identify the range from which these port numbers are allocated. (ii) Identify the byte order used to represent these addresses within the segment header. (iii) If a port number contained in the segment header is passed to the Application layer, identify the function used to convert it to the correct byte order within the application.

#2.Answer T & F.

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.

1.4-6 Maximum end-end throughput (c). 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 (.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-3 Server-1 Host-1 Server-2 Answers: R/4 Host-3 Rs Re 4R Server-4 Host-2 Suppose that R-1 Gbps and Reis 300 Mbps and R, is 200 Mbps. What is the TCP throughout achieved on each of the 4 connections? Re Host-4

An Internet Protocol (IP) address is a unique identifier for a computer on the Internet. How does a mnemonic address work? What is the greatest number of unique domains that the 32 bit representation can accommodate? And how many machines may be included in a domain?

NAT translation table LAN side addr WAN side addr 135.122.200.215 10.0.1.15 10,0.1.13 address 135.122.200.215 S: 10,0,1.27 2 D: 1 D: S: S: D: S: 10,0.1.15 D: 135.122,200,215 10.०.1.22

Computer Science What is the total number of addresses in IPv6 address scheme (give your answer in comma separated actual numeric value)? Give examples of IPv6 address types: a unicast address, a multicast address, a loopback address, and an unspecified address (e.g., when host does not have an address assigned).
