Introduction:
There are two kinds of systems that people can utilize when setting up a network. They can use a distributed system or the other kind of system called a centralized system. In this paper we will find out what can happen as far as the failures in these systems and what if anything can be done to fix these systems when they fail.
Distributed System:
A distributed system is a un-smart computers connected to a network of distributed middleware. This system allows the computers that are connected to communicate with each other and also pool and share their resources such as memory or other significant resources that they need. This also allows the end user to use …show more content…
1. Halting Failures: these failures are from a component aspect. It is when a component suddenly stops working and there is no way to detect this except by a timeout. It is not sending the computer program the message that hey I am still functioning.
2. Fail-Stop: is a halting failure with a notification to the system that something with in the network or program or components is not working right or is about to go down.
3. Network failures: is when some part of the overall network has a break. It can be a small link in the overall chain the cause the network to fail.
4. Omission Failures: is a failure to send or receive messages from a lack of buffering space. This causes the messages to be trashed with no notification to either the sender or the receiver. (birman 2005)
Centralized systems:
Some of the failures that can happen with in a distributed system may also occur within a centralized system as well.
1. Systems act like a single device and have no need to interact with another system or device in order to function.
2. General Purpose: A couple of processors and device controllers that are connected through a common bus and allowed for shared …show more content…
The only way these problems or failures occur within the centralized system is when it is connected to a network. If a centralized system is set up for a single user then these kinds of failures will not happen.
How to fix the failures:
The easiest one of the four failures to fix would be the break in the network line. All a technician would have to do is trying and ping a device from a broken device on the network. If the ping comes back then the technician would know that set of network lines are ok and that the network issue is some were further down the network line. If it does not come back then the technician would know that that line is bad or something with in the NIC has gone bad.
A halting failure would be easy to find within a system because the system device or program would become unresponsive to ques and queries. All the technician would have to do is restart said system and not where and when the failure occur in order to have a record of it and if the failure continues they would know that there is a larger issue and go from there.
