NMS: Network Management Station. Software runs on the manager. The common management
platforms are "Quid View", "Sun Net Manager" and "IBM Net View". Agent is the software of the server
running in the network device.
NMS can send "Get Request", "Get Next Request" and "Set Request" message to Agent. After
Agent gets those messages, it will read or write according to the message type to create Response
message and send the Response message back to NMS. Agent will also send Trap message to NMS
when the device is abnormal.
