Q2.3. (15%) Consider sending a file of F bytes over a path of Q links. Each link transmits at R bps. The network is lightly loaded so that there are no queuing delays at any link. The propagation delay on each link is Tp seconds on average. 1. Suppose the network is a packet-switched virtual-circuit network. Assume the VC setup time is Ts seconds. Suppose the sending layers add a total of h bits of header to the file, and...

QUESTION 1 2 points Save Answer You have a device that wants to transmit many packets to a router, which is sometimes busy serving other users. At every second, your device attempts to send a packet. It succeeds with probability 1/5 and the success of any attempt is independent of the success of other attempts. Let N be the number of attempts until the first success. What type of random variable is N? Bernoulli Binomial Geometric O Poisson QUESTION 2...

Question 10 (10 points) Consider a cache of 8 lines of 16 bytes each. Main memory is divided into blocks of 16 bytes each. That is, block 0 has bytes with addresses 0 through 15, and so on. Now consider a program that accesses memory in the following sequence of addresses: Loop three times: 10 through 20; 32 through 52. Once: 20 through 35. Suppose the cache is organized as direct mapped. Memory blocks 0, 8, 16 and so on...

Please Answer all Questions on Networks, They all involve calculation ( 1-9 Questions) "A single router is transmitting packets, each of length L bits, over a single link with transmission rate R Mbps to another router at the other end of the link. Suppose that the packet length is L= 12000 bits, and that the link transmission rate along the link to router on the right is R = 1000 Mbps. What is the maximum number of packets per second...

1. Let’s consider the network shown in Figure 1 where Snort is
deployed.
1.1: In Figure 1, why is Snort deployed in the DMZ instead of
the Internal Network? (9 points)
1.2: In Figure 1, say True or False to the following statement:
“Snort can see both incoming packets from the left firewall and
outgoing packets from the right firewall”. (5 points)
1.3: In Figure 1, assume a packet P matches the following Snort
rule when the packet is analyzed...

Question 1 (20 points: Events, counting, and properties f probabniny Consider the network shown below. There are two kinds of links in the network. Each link of kind o-p +0 fails with probability p and that of kind O 4+0 fails with probability q. Each link is assumed to fail independently of the other. We say that a path is successful if no link in the path fails. For example, the path S-B-T succeeds if none of the links S...
