Information about Network Management
Network management refers to the maintenance and administration of computer networks and telecommunications networks at the top level.
Network management is the execution of the set of functions required for controlling, planning, allocating, deploying, coordinating, and monitoring the resources of a network, including performing functions such as initial network planning, frequency allocation, predetermined traffic routing to support load balancing, cryptographic key distribution authorization, configuration management, fault management, security management, performance management, bandwidth management, and accounting management.
A large number of protocols exist to support network and network device management. Common protocols include SNMP, CMIP, WBEM, Common Information Model, Transaction Language 1, Java Management Extensions - JMX, and netconf.
Data for network management is collected through several mechanisms, including agents installed on infrastructure, synthetic monitoring that simulates transactions, logs of activity, sniffers and real user monitoring. In the past network management mainly consisted of monitoring whether devices were up or down; today performance management has become a crucial part of the IT team's role which brings about a host of challenges -- especially for global organizations.[1]
Note: Network management does not include user terminal equipment.
