Question
How is the cost/metric of a route determined in OSPF.
Then, let's say that for a packet to get to a destination, it passes over the following 5 networks: Gigabit LAN, 100 Meg connection to ISP, 10 Gigabit ISP network, 10 Megabit ISP connection at remote end, and Gigabit LAN. Calculate the cost of this total route.

- How would you write a system of linear equations based on the given scenario and directions? Scenario You are employed as a network engineer and have been asked to analyze a communication network to determine the current data rates and ensure that the links aren’t at risk of “reaching capacity.” In the following figure of the network, the sender is transmitting data at a total rate of 100+50 = 150 megabits per second (Mbps). The data is transmitted from the sender to the receiver over a network of five different routers. These routers are labeled A, B, C, D, and E. The connections and data rates between the routers are labeled as x1,x2, x3, x4, and x5 . Directions For this assignment, you will analyze the communication network and solve for the unknown data rates using a variety of techniques. The system can be modeled mathematically as a system of linear equations by writing an equation for each node/router in the network. Each of these equations can be written by noting that the sum…arrow_forwardConsider the network shown below, and Dijkstra's link-state algorithm. Suppose that Dijkstra's algorithm has been run to compute the least cost paths from node E to all other nodes. Now suppose that source node E has a packet to send to destination node A.

- Also answer: 2. The ISP that owns all these networks is short on IP addresses, so they use a NAT router for R2. How many public IP addresses will C and D use together assuming they use as many private 10.X IP addresses as they can? How many total public IP addresses will be used by the entire network? Why doesn’t the ISP care about how many private IP addresses are used?arrow_forwardshow step by steparrow_forwardYou are employed as a network engineer and have been asked to analyze a communication network to determine the current data rates and ensure that the links aren’t at risk of “reaching capacity.” In the following figure of the network, the sender is transmitting data at a total rate of 100+50 = 150 megabits per second (Mbps).
