1) Consider the switching networks shown in Fig. 1. Let Ai, A2, and As denote the events that the switches s1, s2, and s3 are closed, respectively. Let Aab denote the event that there is a closed path between terminals a and b. Express Aab in terms of Ai, A2, and A3 for each of the networks shown. 2 Figure 1
In the electrical network shown below, the four relays are closed at a given time It is equally likely that each relay w work or not when it is closed. What is the probability that a closed path will exist from A to B? 4

Consider the network of four resistors shown in the diagram,
where R1 = 2.00 Ω , R2 = 5.00 Ω , R3 = 1.00 Ω , and R4 = 7.00 Ω .

Assume that failures of different links are independent Link 1 Link 2 B A Link 5 Link 3 Link 4 1. Assume that p = 1/3. Find the probability that there exists a path from A to Balong which no link has failed. (Give a numerical answer.) 2. Given that exactly one link in the network has failed, find the probability...

consider a network using packet switching, that consist of 4 routers and two host: Host A and Host B with distance between the two hosts is 10000 Km. assume every router has processing time = 2 s, and queueing time = 2 s. The speed of light = 2x108 m/s and all the links have a bandwidth of 5Mbps. Calculate the queuing delay for the whole network.
one important factor in the total delay of a store-and-forward packet-switching network is how long it takes to store and forward a packet through a switch. If the switching time of each switching device is 1 microsecond, is this likely to be a major factor in the response of a client-server system where the client is a computer you use to access the internet, and the server is somewhere in Europe? Explain your answer. You can assume the average propagation...
