Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.

Q3.Unless specified otherwise, use the free space propagation speed of light 3x108 m/s to calculate the propagation delay. For numerical calculations, the results must show the appropriate unit. Show me a complete solution NOT THE AI SOLUTION. Consider a digital multimedia transmission system. Separate audio and video coders are used to encode these signals. Audio and video bits are packed in packets together and transmitted over a transmission link. Each packet is 2,000 bytes long, which includes a 48-byte header. The system generates one packet every 40 ms. Calculate the following values:a. The minimum data transmission rate required to support the above system.b. The minimum signal-to-noise ratio (SNR) in dB required to transmit the above audio and video information. Assume a 400-kHz transmission channel bandwidth is used.c. The end-to-end packet delay over a 50-km link, using answer in Part a).

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…
Computer A is sending a 100 kByte long file to Computer B via packet-switching over two consecutive 10 Mbps links of 1000 km length each.Assume that the signal propagation speed on both links is 2.5 x 108 m/s.Furthermore, assume that the maximum length of a packet is 1500 bytes and that Computer A fills each packet to the max, if possible. If transmission starts at time t=0, how long (in seconds) does it take until Computer B has received the last bit of the complete file transfer?Assume that the switch between link 1 and 2 is a "store-and-forward" switch. Furthermore, assume that processing and queuing delays are negligible and no other stations are using the links.
Problem with constructing MAC. The messages X to be authenticated consists of z independent blocks, so that: X = x1||x2|| . . . ||xz, where every xi consists of |xi| = 8 bits. The input blocks are consecutively put into the compression function ci = h(ci−1, xi) = ci−1⊕xi At the end, the MAC value: MACk(X) = cz+k mod 28 is calculated, where k is a 64-bit long shared key. Describe how exactly the (effective part of the) key k can be calculated with only one known message X.
