Network Management Overview
During the lifecycle of a computer network, it faces complexities that need to be solved. As an organization becomes increasingly dependant on the computer networking services, keeping these services running accurately are necessarily required for the smooth operations within an organization. Network management is a procedure in which a computer network is operated, configured, secured, troubleshoot, monitored and maintained by means of management/monitoring tools and techniques and network administrator is responsible for accomplishing the administrative tasks. Managing a computer network involves a number of tools, applications, devices and techniques.
The level of management increases as our network expands and new technologies, devices and services are added in our network such as VOIP, ISDN, Packet switching, circuit switching, routers, clustering, centralized storage, firewall software/hardware and video streaming. Automating the tasks such as logs generating, alerts, scheduled downloading/uploading, virus scanning, bandwidth monitoring and printing certainly provide ease in the administrative and network management tasks of the network administrators.
There are certain software that can be used to manage the computer network such as Nsauditor Network Security Auditor, IPSentry Network Monitoring Suite, LanGuard, Alchemy Eye and Network Administrator's Toolkit. In the LAN/WAN network management model there are six key areas that need to be discussed.
Fault Management
Fault management is carried out automatically or through network administrator’s manual work. The purpose of faulty management is to keep logs, isolate the problems and troubleshoot them in a timely manner to keep the computer network running smoothly and effectively.
Security Management
Security management includes securing the network resources, applications and devices from the unauthorized access. Security management also includes implementing the security policies, configuring the firewall, intrusion detection, preventing virus attacks and securing the network from internal and external threats by securing management tools and techniques.
Performance Management
Performance management includes the various aspects of the network performance to maintain the good and acceptable performance in a computer network.Configuration ManagementConfiguration management monitors the configurations such as TCP/IP, operating system, SMTP, DNS, DHCP, FTP, Firewall and network devices such as LAN card, switch and router, in a computer network. All the configurations can be stored in a centralized database for quick access and these configurations provide help while troubleshooting the problems.
Accounting Management
Accounting management involves the utilization of all the network resources. Controlling the network utilization helps in preventing the problems such as delay in network response and bottleneck. Measuring the network resources utilization is helpful in allocating usage quote of the network resources and in providing the optimized performance to all the users.
Application Management
Application management involves the fast deliver of the applications to the network users. You can prioritize application traffic, control bottleneck and accelerate the performance of the applications.
The other functions that are the part of the computer network management includes planning, deploying, configurations, coordinating, troubleshooting, monitoring the network resources, traffic routing, load balancing, cryptography, authorization, bandwidth management and security management.
