Network management explained.

Network management is the process of managing and controlling the hardware and software resources of a computer network. It involves monitoring and maintaining the network infrastructure to ensure that it is functioning properly and efficiently, and to identify and resolve any issues that may arise. Network management tasks can include configuring and managing network devices such as routers, switches, and firewalls, monitoring network performance and traffic, and troubleshooting network problems. Network managers may also be responsible for implementing and enforcing network security measures to protect against cyber threats and unauthorized access. Network management is important for ensuring that a network is reliable and performs well, and for maintaining the confidentiality, integrity, and availability of the data transmitted over the network.

Types of Network Management Operations

There are several types of network management operations that are commonly performed to ensure the proper functioning of a computer network. Some examples include:

  1. Configuration management: This involves configuring and maintaining the settings and parameters of network devices and systems to ensure that they are properly configured and working as intended.
  2. Performance management: This involves monitoring the performance of the network and identifying any issues that may be affecting its performance, such as bottlenecks or congestion.
  3. Security management: This involves implementing and maintaining security measures to protect the network and its data from unauthorized access and cyber threats.
  4. Fault management: This involves identifying and resolving issues that may arise on the network, such as hardware or software failures, and restoring normal operation as quickly as possible.
  5. Asset management: This involves maintaining an inventory of all network assets and ensuring that they are properly configured, maintained, and replaced as needed.
  6. Capacity planning: This involves forecasting future network needs and ensuring that the network has sufficient capacity to meet those needs.

Overall, these types of network management operations are important for ensuring that a network is reliable, performs well, and is secure, and for maintaining the confidentiality, integrity, and availability of the data transmitted over the network.

Phases of network management

There are generally three phases of network management:

  1. Planning: This phase involves identifying the objectives and requirements of the network, and developing a plan to meet those needs. This may include determining the types of devices and technologies that will be used, and defining the network architecture and topology.
  2. Implementation: This phase involves physically setting up the network, including installing and configuring devices, cabling, and software, and testing the network to ensure that it is functioning properly.
  3. Operation and maintenance: This phase involves maintaining and managing the network on an ongoing basis, including monitoring performance, configuring and updating devices, and troubleshooting issues that may arise. It also involves regularly performing tasks to ensure the ongoing reliability and performance of the network, such as applying software updates, replacing faulty hardware, and performing preventive maintenance.

Overall, these phases are important for ensuring that a network is set up and maintained properly, and for ensuring that it meets the needs of the organization.
