- Discuss the invocation semantics that can be achieved when the request-reply protocol is implemented over a TCP/IP connection, which guarantees that data is delivered in the order sent, without loss or duplication. {Note: Take into account all of the conditions causing a connection to be broken}d) State all the random access protocols and controlled access protocols. Explain why collision is an issue in random access protocols but not in controlled access protocols.Please refer to this textbook: “A. Silberschatz, P. B. Galvin and G. Gagne, “Operating System Principles,”7th Edition, John Wiley & Sons Inc., 2006.” And answer the following questions: Question3: The TCP layer does not deal with: Reliable data transfer. In-order data transfer. Flow control. Secure data delivery.

In light of these factors, it is now considered antiquated. A serious discussion is required.
- Design a leaky bucket (LB) scheme to police the traffic flow on a user line in an ATM network to ensure the following traffic contract: Peak Cell Rate (PCR) = 22 cells/millisecond Sustainable Cell Rate (SCR) = 11 cells/millisecond Maximum Burst Size (MBS) = 4 cells Consider the line on which the leaky bucket scheme is installed to have a speed of ? = 88 cells/millisecond and the leak rate of every leaky bucket used to be 1 liquid unit per cell time. Also, assuming that the user continuously sends traffic at 88 cells/millisecond (i.e., at the speed of the line, thereby violating the contract), draw a diagram to show the output traffic pattern of every leaky bucket used in your scheme.Assume a system of 32 cells with a cell radius of 1.6 km, a total of 32 cells, a total frequency bandwidth that supports 336 traffic channels, and a reuse factor of N= 7. (a) If there are 32 total cells, what geographic area is covered, how many channels are there per cell, and what is the total number of concurrent calls that can be handled? (b) Repeat for a cell radius of 0.8 km and 128 cells. Width = 11 x 1.6 = 17.6 km Width = 21 X 0.8 = 16.8 km (a) Cell radius = 1.6 km (b) Cell radius = 0.8 km - Height = 5 xV3 x 1.6 = 13.9 km Height = 10 xV3 x 0.8 = 13.9 kmImagine a scenario where people in the city use dynamic route guidance system (DRG). At a specific moment, a congestion happens on a specific road. Explain what will happen if the dynamic route guidance system directs all users in the congestion area to another road which is the same for all of them. Describe how the DRG works on this scenario, describe the problem, and describe the solution.
