Network Management System

 In a big computer networks the centralized management of a network is required to monitoring, planning, allocating, security, deploying, coordinating and configuring the computer network. Network management means managing the administration and security, risk, reliability and performance of a network over a very large scale. There are different software and hardware components are available to manage the computer network locally or remotely.

Being a network administrator or IT manager, you have to ensure the security of your computer network i.e. your network is protected from the unauthorized users and from hackers.  For this purpose you have to restrict the user rights, implement the securities policies, use firewalls and monitor the network traffic and performance with the different tools. Some high end software produces real time graphical views to monitor the network activities. As the network expand the maintenance policies and strategic growth planning is required to manage the network.Network management architecture depends on the client-server relationship i.e. some software applications are installed at all the workstations and all the activities of the workstations are monitored at the server. When a system alert is received at the server, certain actions such as event logging, system generated messages to users and system shutdown is performed. The protocols that are involved in the management of a network are simple network management protocol SNMP and common management information protocol CMIP. ISO has contributed to a large extent in making the standards of managing and administering a network. The management of a computer network involves certain things such as security, risk, performance, fault, system, accounting, configuration load balancing, and traffic routing and traffic management. The purpose of the performance management is to measure the performance such as the user’s response time and application performance. When a certain performance threshold is reached, a system alert is generated and sent to the server and it is monitored and certain actions are performed in response of it. Security management is to secure the network from the unauthorized users and also secure the resources and sensitive data. Certain security policies and security systems are enabled to ensure the security of the network. The purpose of the fault management system is to track records of the faults, isolate faulty software or hardware and fix them. There are certain network management systems and software being used for optimizing the maximum resources allocation, reporting capabilities, real-time fault detection and reduces the network downtime. This software provides the comprehensive management features such as for monitoring, analyzing, managing, fault detection and security. Using a good network management system reduces the workload of the IT support staff, measure the network performance and provide the real time statistics of all the computers in a network. Certain software is used to keep track of the bandwidth usage of network and the tracked information is stored in the centralized database for analysis and monitoring. Through this data you can analyze the bandwidth requirements of your network and can plan for the increase in bandwidth. A good network management system ensures that a network is being used efficiently and it provides organization’s productivity, security, scalability and flexibility. For the flexible working, businesses should deploy a good centralized network management system so that employees can provide timely reports, coordinate with colleagues and perform their duties effectively. Make sure your network is secured by installing
