A NETWORK MANAGEMENT METHOD BASED ON SNMP

摘要

(a) initiating and initializing the NMS; (b) the NMS detecting communication state and key state of the network element to determine whether or not a key synchronization with the network element is required; (c) the NMS generating a SNMP Get request for querying the current information on the network element and sending it to the network element that returns a SNMP response containing the queried current information on the network element; (d) the NMS generating a SNMP Set request for controlling/configuring the network element, encrypting and sending the generated SNMP Set request to the network element that returns a SNMP response containing a control/configuration result. Therefore, by encrypting the SNMP request, the managed network can be protected from being attacked via the SNMP Set request, thereby ensuring sufficient security.
