Network management involves administration and maintenance of large networks, including security, routing, configuration, and accounting management. It uses various protocols and tools to ensure efficient functioning and financial stability.
Network management is the higher-level administration and maintenance of large networks, often in areas such as computers or telecommunications, but not including user terminal equipment. It often involves functions such as security, monitoring, control, allocation, implementation, coordination and planning. A large number of protocols, including SNMP, CMIP, the Common Information Model, and Java Management Extensions, govern this field and exist to support it.
Routing, which refers to the process of selecting paths in a computer network to send data over, is an important area of network management. In this area, 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 which keep a record of the most efficient routes.
Security management is also a key component of management. This involves protecting a network from unauthorized access and includes many secondary functions, such as authorizing subscriber access, controlling the distribution of cryptographic coding material, and distributing and reporting security-related events.
Configuration management covers both the security and quality areas of network management. Refers to managing security features in a network by controlling changes to software, hardware, firmware, documentation, and test features in a system. This area keeps the system under control in its evolution and growth, maintaining quality and safety.
Software configuration management can be divided into two main areas. The first involves archiving entities from a software development project and is sometimes called component repository management. The second area is concerned with producing and modifying these entities and is often referred to as technical support.
Successful network management also uses accounting management, which monitors and reports the financial status of the network. This is done through the analysis, planning, control of financial data reporting programs and reporting for management decisions. This area covers bank account maintenance, cash flow statement development, and cash flow and financial health analysis.
