Fault Analysis Essay

The entering of data is an important part of the computer operator’s daily routine. Computer operators may also have to take calls from customers complaining of computer system issues. The computer operator will diagnose the problem and then walk the individual through how to fix the situation. Should further help be needed, the computer operator will contact the necessary parties or advise the customer how to do so on their own.

A root cause analysis is a systematic approach utilized to identify problems within an event and create a plan for preventing that problem from recurring in the future. To be effective, a timeline of the events are created to help identify those areas that may be the reason for the problem or event, and the relationship between the causal factors and those factors identified to be a reason for the event to have occurred.

hit by a bus. To mitigate this, hire additional resources or cross train resources to handle the system/hardware as a backup function in the even he/she is

d) The information is acquired on the data bus and send it to TDO. (Alghafli, Jones, and Martin. 2012).

Monitored the network congestion in order to achieve the optimal performance out of a network infrastructure.

Answer the following questions based on the packet capture that precedes them. You may research any of these on the Internet if you need to do so.

This type of failure can only happen on a distributed system. An example of this is: in a distributed system, 1 computer sends a message to another computer either asking the computer if it’s responsive, requesting information from the computer, or replying back to the other computer that asked if it is responsive. This can cause problems when computer A sends computer B a message asking if it’s responsive, however the message never gets to computer B therefore computer B never responds and computer A assumes that computer B is down.

Builds topologies map (Every node knows how to reach to its directly connected neighbors and by making sure that the total of this acknowledge is distributed to every node then every node will have enough information to build a complete map of the network).

The ‘network worker’ then takes the data package from the transport worker and adds routing information as to assign the package with a specific PO BOX address or rather a network address (if you may) in order to navigate through the network. The ‘network access worker’ then inserts error-checking information and prepares the data for transmission. The ‘physical worker’ finally transmits the data via a physical or wireless medium so that the second CEO receives the message. The following figure shows how the data is transmitted from the application layer to the physical layer.

fault resiliency are critical. CISCO system ASA 5510, on the other side, is used for remote

The basic idea is to set up a monitor at each node in the network to produce evidences and to share them among all the nodes .An evidence is a set of relevant information about the network

  * Networking comportments of IT infrastructure (XML interface; Electronic interface; IBM AS 400 Platform; Windows 2000 Platform; Local area networks).

of layers to this software. At the top level, the computer sends some type of "packet" of data to the device

For our purpose we will focus on ECHELON was collects and analyzes signals of various networks. ECHELON was created to monitor

This system is divided in a knowledge base and inference rules. In the video, this system is used when it comes the control center. The employees are checking flights and regulating flows thanks to precious information given in their computer like the weather, the flow rate and a packaging monitoring.
