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 Rs Re Host-3 Host-2 Suppose that R-1 Gbps and Reis 300 Mbps and R. is 200 Mbps, What is the TCP throughout achieved on each 4R Server-4 Rc Host-4 eacef the 4 connections?

Only typing answer Please explain step by step without table and graph thankyou

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. Host A Local Area Network (LAN) IP: 192.168.1.2 Port: 5252 Source IP…

A protocol for interleaved deliveries from two senders. Consider the figure below, which shows three nodes, A, B, and C. A and C are connected by a bi-directional channel; B and C are connected by a separate independent bi-directional channel. A and B can not communicate with each other. The goal of the protocol you will design is to transfer data from A and from B in a coordinated manner to C. The protocol between sender A and receiver C (and sender B and C) operates as follows. Senders A and B each receive data from their upper layer, via a call to rdt_send(data), which returns the data to be sent, exactly the same as the rdt protocols we studied in class and in the text. Senders A and B are to reliably send their sequence of data obtained via subsequent calls from rdt_send(data) to C. Node C should deliver to its application layer (via a call to deliver_data())a data item from A (as soon as it has correctly received that data item), followed by a data item from B (as soon as it has…

Help please. I will like if it is correct . otherwise thumb's down

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.)

Consider a router that interconnects three subnets: Subnet 1, Subnet 2, and Subnet 3. Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.10.128/24. Also suppose that Subnet 1 is required to support at least 50 interfaces, Subnet 2 is to support at least 100 interfaces, and Subnet 3 is to support at least 12 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints.
