Configuration of network management system: centralized network management and distributed network management

1. Centralized network management: all agents work together under the supervision and control of the management station to achieve integrated network management.

Management station: NMA+ | NME+APPL+COMM | + OS

Workstation: NME+APPL+COMM | + OS or NME | + COMM | + OS

NME acts as an agent module in the workstation

The function is:

1) collect statistical information on communication and network activities

2) Test the local device and record its status information

3) store relevant information locally

4) transmit statistics or equipment status information in response to the request of the network control center

5) set or change the parameters of the equipment according to the instructions of the network control center.

2. Distributed network management: the distributed management system replaces the single network control host, and the geographically distributed network management client interacts with a group of network management servers to complete the network management function.

Advantages: sub-department management can be realized: that is, each client can only access and manage part of the network resources of the department, while a central management station implements global management.

3. Principal-agent: if the managed device cannot load the agent or does not support it, it can be managed by the agent.

A standard network management protocol is running between the principal agent and the management station.
