What is network management?
Network management is the top-level administration and maintenance of large networks, often in areas such as computers or telecommunications, but not including user terminal equipment. In network management, functions such as security, monitoring, control, allocation, deployment, coordination and planning are executed. Network management is governed by a large number of protocols that exist for its support, including SNMP, CMIP, WBEM, Common Information Model, Java Management Extensions, Transaction Language 1, and Netconf. Routing, which refers to the process of selecting the paths in a computer network on which to send data, is an important area of network management. In this area of network management, logically addressed packets are passed from their source to their destination through nodes, which are called routers, in a process called forwarding. This is usually based on routing tables that maintain a record of the most efficient routes. Security management is also a key compone
Network management systems monitor and control the electricity network to keep power flowing and to preserve the balance between generation and consumption. They are the brain and central nervous system of the network and are known in the industry as SCADA, or systems control and data acquisition. The background and technology The roots of power control go back to the 1920s when ABB supplied its first remote control system for a power plant. It was not until the 1960s and the advent of computerized process control that modern power network control systems as we know them today became possible. ABB has been at the forefront of developing this technology over the past 40 years and has delivered more network management systems than any other company. In a SCADA installation, meters collect information from hundreds of thousands of data points in national and regional power networks and feed it into a computer system for storage and analysis.
