The functions of network management

Planning is very important in network management. Before you do anything, you need to plan the network as consultant. You need to plan how long it take to finish and let the customer or people above you know when the network will finish. A big advantage of planning is that it allows you to know how much money you need and expect if that money need to be exceeding the budget. It also allows you to be more specific on what type of hardware and software needed, as well as any other equipments’.

Using the network simulator to design the network and you may need to decide where you want to install new devices to design the network. You can use Hub or Switch to connect the computers in the network, switch would be better because it know where to send the information and will send it direct to one that node while Hub send date to all attached node and only the one that has MAC address on date would accept.

After designing the network, you need to test it and show it to the customer if they may want to change the layout.

Installing

You need to decide what hardware and software you need to install before you start designing the network and how long it will take to install, and you need to know accurate amount time required therefore you can prepare for any trouble it may cause. You need to decide what kind of cable you are going to use.

Configuration

Configuration is to set up the services in server and control the network. Configuration is to set up certain rolls on server for example what site the users can go on, sending files, automatic IP address and DNS. The configuration is to set up the network and connect all the computers.

Security

Security is what you need for your network and you must have alarm or when something goes wrong. You need alarm when someone can’t log in because they may need help to log in but if someone continuously fails to log in then you will be alerted that they could be trying to hack the network or system.

Account management

Account management is where you can add user and user details on the network. The users will have password to log in to the network. you may need to disable the account after few weeks and monitoring the account.

Account management includes all of the details of the accounts on the network. They could have a standard format for account names such as the year the employee joined, followed by surname, followed by forename to prevent users having the same usernames on the network. The accounts will passwords for security. There can be a minimum length on passwords; they may also require capitals letter, number and symbols in the passwords. The password may also expire after a certain number of days. The location and access to files is also essential.

Whether there is a standard format for account names and the security of the accounts using passwords and whether the passwords should have a minimum length and whether they should expire, if so when. The location of individual users files.

Data logging

The computers are usually in the college for about 5 years and are constantly monitored to see how they’re doing and their condition. If the staffs think they are suitable for another year then they will be used again. Every action on computers is recorded in some way and staff checks these logs for any patterns that are going on to see if it is a hacker or if anyone is downloading anything illegal.

Performance management

The main job role of performance management is to measure network performance to make sure that the network performance is on best level. It’s important for performance managers to check the network regularly to see if the backups, hard and software. This will help in improving a company’s standards, quality and reputation, as well as saving money needed if a system had faults.

Fault management

The main job of Fault management is concerned with the identification of the discrepancies of the network. Fault management system is helpful in isolating the faults and vulnerabilities present in the network and uses trend analysis to identify errors so that the network remains active at all times.

The main job of a fault management is to deal with any hardware or software faults and failures that stop the network to work correctly. Faults such as hardware corruption can result in data loss and damage to network. This can be prevented if a fault manager monitors the performance of hard drive to see if it functions correctly. Another way to prevent from such faults and losses is to have spare piece of hardware or software which can be used if faults were found in a network.

User response time

The user response time is the amount of time a network takes to respond to a user’s request. The amount of time taken by the network to respond to a user depends on the amount of traffic passing through the network. For example, if the majority of people in the UK try to go on the Yahoo.co.uk at the same time, which is requested from the user, the network has to respond for all at once and it won’t be able to so it becomes a lot slower and sometimes it won’t even work.

Checking performance

To ensure that a network functions correctly, it’s important to check the performance of the network regularly if not daily, which will help to find any errors that affect the performance of the network. For example the network might be slow because of server problems or too much downloading at once. Checking network performance can be done by having automatic monitoring software.

Reporting

It’s important to store and log the activities and information on a network and report it to people who are in charge. For example, if in a company, staffs are sent on their work without having managers checking on what they are doing, they can be off task and use the network /internet for other purposes. Useful pieces of software or firewall can be used to block common web pages as well as monitoring what is searched for on the network. This can help a company in saving time, money for other types of monitoring equipment as well as number of staff and managers needed to supervise.
