Consider a two-link network where Host A is connected to the router by a 1 Mbps link with 10 ms propagation delay and the router is connected to Host B by a 15 Mbps link with a 25 ms propagation delay. Host A sends a 1500-byte packet to Host B. What is the transmission delay (in ms) of the packet from Host A to the router?
The next three questions are related to the local area network shown below. In this network computers attached to links 1 & 2 send data to the server attached to link 3. The three devices are connected through a router. Link 1 Link 2 Link 3 Following parameters of the network have been provided. Propagation delay in link 1-138 micro seconds Propagation delay in link 2-309 micro seconds Propagation delay in link 3-216 micro seconds Frame size 1432 bytes ACK...
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...
Transmission Delay Consider sending N packets each of length L bits from Host A to Host B, as shown in the figure below. Assume that the links between Host A and the Router and between the Router and Host B each has a transmission rate of R bits per second. Assume all buffers are of infinite capacity. Ignore all processing and propagation delays. a) Express the delay it takes to send 2 packets from A to B as a function...
Consider the scenario shown below, with four different servers connected to four differe over four three-hop paths. The four pairs share a common middle hop with a transmission capacity of R 200 Mbps. The four links from the servers to the shared link have a transmission capacity of Rs = 80 Mbps. Each of the four links from the shared middle link to a client has a transmission capacity of Rc 10 Mbps per second. You might want to review...

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...
