Consider a channel between a pair of processes as a hollow pipe as shown in the following figure. A file of 1000 bytes needs to be transferred through the channel with a data rate of 11Mbps. Since the propagation speed depends on the physical medium of the link, in the case of coaxial cable it is 2 x 10 m/s. Calculate the bandwidth delay product with the assumption that the queueing and processing delays are 1 ms and 3 ms, respectively? Note: delay- (Propagation time Transmission time Queueing Time Processing Time). 100 3. You are required to elaborate appropriate protocol with the help of a sequence diagram when two directly connected stations want to use a channel for data communication, however, it is to be noted that they cannot communicate directly; but they have to exchange information through a designated device? Cosial Cable 4. Based on the wireless scenario given below, where, N and No want to communicate with N: at the same time. What problem can arise and how that problem can be resolved, explain the solution with the help of a sequence diagram? server computers Latest network medium should be used - Latest network security devices should be used By considering the above scenario answer the following questions: i). What type of network topology you suggest for the above network scenario? Why you suggest that network topology, justify your answer in your own words? ii). What type of network you suggest for the above network scenario to share the important data/files among all users? Why you suggest that network, justify your answer? iii). Write the name of the cables which are used to connect the following network devices in the new network. (2 marks) iv). IP Plan for the above network scenario-write the correct IP address in the following table. Use Class-C IP address: 192.168.1.0 devices within IBRICT network? How the data is being sent through this medium? ii). What network medium can be used to connect a network in Oman to connect with the network in Saudhi Arabia? How the data is being sent through this medium? iii). Differentiate the above mentioned network mediums. Question 4: . As a network designer, you are asked to create a new network with 2 departments, each department with 1 computer. Connect both departments by using a router. Marking Scheme (7 Marks): O Network design - 2 marks i) Names of the devices- 1.5 marks i) Assigning IP address- 1.5 marks v) Check the connectivity - 2 marks and C as shown in the Fig. 1, where Nodes A and C are far away from each other. The signal strength of Nodes A and C are shown in Fig. 2. Please answer the following questions. A B A's signal strength C's signal strength space Fig. 1 Wireless Network topology Fig. 2 Signal strength vs. space 1 Please describe in which scenario a collision can happen in the network shown in Fig. 1. (10 points) 2 Please state the concept and working process of the mechanism that can address the problem you described in Question 2.1.
