In this problem, we consider sending real-time voice from Host A to Host B over a packet switched network (VoIP). Host A converts analog voice to a digital 64 kbps bit stream on the fly. Host A then groups the bits into 56-byte packets. There is one link between Hosts A and B; its transmission rate is 2 Mbps and its propagation delay is 10 msec. As soon as Host A gathers a packet, it sends it to Host B. As soon as Host B receives an entire packet, it converts the packet's bits to an analog signal. How much time elapses from the time a bit is created (from the original analog signal at Host A) until the bit is decoded (as part of the analog signal at Host B)?

Network & Data Communcations
While developing a reliable transport protocol, early versions of the protocol discussed in class used a NAK message, sent by the receiver to the sender to indicate a packet was not correctly received. This kind of message, however, is not found in further protocols, like GBN, SR or even TCP. Why not? In other words, why don't these protocols provide a way to signal to the sender that the received message was received with an error
You are employed as a network engineer and have been asked to analyze a communication network to determine the current data rates and ensure that the links aren't at risk of "reaching capacity." In the following figure of the network, the sender is transmitting data at a total rate of 100+50 = 150 megabits per second (Mbps). The data is transmitted from the sender to the receiver over a network of five different routers. These routers are labeled A, B, C, D, and E. The connections and data rates between the routers are labeled as x1, x2, X3, x4, and x5. B (()) Sender 100 50 A X₂ c (()), X3 X₂ X₁ E (()). X5 X5 X₂ X₂ •D ((cp)), 120 Receiver Directions In this project, you will analyze the communication network and solve for the unknown data rates using a variety of techniques. The system can be modeled mathematically as a system of linear equations by writing an equation for each node/router in the network. Each of these equations can be written by noting that the sum of inputs must…
An input string S of length N is transferred through the network using a special protocol. The protocol can send the string through a series of operations. In one operation, we can choose a lowercase english alphabet and do one of the following: Transfer 1 copy of C through the network. Transfer 2 copies of C through the network. Each of the above transfers take 1 unit of time. Find the minimum time in which we can transfer the entire string S through the network. Note: Please Answer Python only Input 1 5 cbcdc Output 5

Consider two systems P and Q connected via a router R with the bandwidth of 2 Gbps. The length of the packet is 1000 bytes. The propagation delay between P and Q is 200 microseconds. The distance between the P and R is 10 km while the distance between R and Q is 5 km. The propagation speed in meter per second if each link is having the same 10³ km/s? propagation speed is
A TCP connection is established through 10 wireless hops in an acoustic underwater ad hoc network. Assume that each hop is 100 meter in the average, acoustic signals travel 1500 meter per second, 10 kilobit data can be sent per second over a link, the source node has one megabyte of data to send, the receiver window size is 64 kilobytes, the maximum segment size is 1 kilobyte and the average processing delay for routing at each node is one millisecond. Assume also that the following segments do not reach the destination: 67, 112, 137. What would be the average utilization of the links for this connection if there is not another communications through them? Explain an alternative approach to increase the bandwidth utilization?
