Abstract
The invention discloses an SNMP (simple network management protocol) based network management system and network management method. A server of the SNMP based network management system comprises a heartbeat detection unit, a storage unit and a judgment unit, wherein the heartbeat detection unit is used for detecting whether messages matched with IP (internet protocol) addresses of the server and sent by devices are received or not; the storage unit is used for storing the IP address of each device and covering receiving time of the stored received messages matched with the IP addresses of the server and sent by all the devices; the judgment unit is used for judging whether a time interval between the current time and the receiving time of each message matched with the IP address of the server and sent by each device is less than or equal to a preset time interval or not, and acquiring judgment results. Under the condition that the devices do not respond to the heartbeat messages sent by the server in time, communication status between the server and the devices is acquired through the judgment unit according to the last receiving time of the messages sent by the devices and the preset time interval, and accordingly accuracy in heartbeat break judgement is improved.
Description
Technical field
The present invention relates to technical field of network management, particularly relate to a kind of network management system based on Simple Network Management Protocol (SNMP) and network management.
Background technology
Network management system has a standalone module, for the state whether UNICOM of responsible detection managed devices, also heartbeat detection unit is referred to as, this unit is the basis of follow-up management configuration, network management system can for the obstructed device customizing alarm of heartbeat and prompting, refusal user is configured to promote Consumer's Experience, effective optimizing user maintenance work.
Because being managed by snmp protocol between most of server and managed devices, and traditional heartbeat detection mechanism is normally by being similar to the communication that User Datagram Protoco (UDP) (User DatagramProtocol, UDP) message carries out between equipment and server.Particularly, send heartbeat message by server periodic (customizable) to managed devices, if there is back Bao Ze to be judged to be, heartbeat can reach; As do not have message then adopt retry, whether the restriction of number of retries decides heartbeat and can reach in addition.
But, the shortcoming that traditional heartbeat detection mechanism exists has: can cause erroneous judgement under system is in busy situation, because the speed of service of the speed of service of managed devices and server is two magnitudes substantially, when equipment is busy with finishing sector business, can the heartbeat detection message of response server in time, cause response message time-out, thus heartbeat is judged by accident.
Summary of the invention
For the problems referred to above that traditional heartbeat detection mechanism exists, now provide a kind of and be intended to realize improving the network management system based on SNMP and network management that judge heartbeat break-make accuracy.
Concrete technical scheme is as follows:
Based on a network management system of SNMP, comprising:
A plurality of equipment, each described equipment coupling has unique IP address;
One server, simultaneously with a plurality of described equipment connection, described server sends to each described equipment the heartbeat message that coupling has the IP address of described equipment with predetermined period, and described server has the message of the IP address of described server in order to the coupling receiving each described equipment transmission;
Described server comprises:

Memory cell, connects described heartbeat detection unit, in order to store the IP address of each described equipment, and covers the time of reception that the coupling storing each described equipment transmission received has the message of the IP address of described server;
Judging unit, connect described memory cell and described heartbeat detection unit, in order to judge that the coupling that each described equipment sends has the time of reception of the message of the IP address of described server and the time interval of current time whether to be less than or equal to prefixed time interval, obtain judged result.
Preferably, when the time interval of current time is less than or equal to described prefixed time interval, described judged result is that the communications status between described server and described equipment is normal.
Preferably, current time interval greater than described prefixed time interval time, described judged result is that communications status between described server and described equipment is abnormal.
Preferably, also comprise:
Transmitting element, connects described heartbeat detection unit, has the heartbeat message of the IP address of described equipment in order to send coupling.
Preferably, also comprise:
Receiving element, connects described heartbeat detection unit, and the coupling sent in order to receive each described equipment has the message of the IP address of described server.
Based on a network management of SNMP, be applied to the described network management system based on SNMP, the method for described server to the network management of each described equipment comprises the steps:
A1. described server sends to described equipment the heartbeat message that coupling has the IP address of described equipment;
A2. the coupling judging whether to receive the transmission of described equipment has the message of the IP address of described server, if so, performs steps A 3, if not, performs steps A 4;
A3. the communications status between described server and described equipment is normal, terminates;
A4. judge that the coupling that described equipment sends has the time of reception of the message of the IP address of described server and the time interval of current time whether to be less than or equal to described prefixed time interval, if so, perform steps A 3, if not, perform steps A 5;
A5. the communications status between described server and described equipment is abnormal, terminates.
Preferably, before the described steps A 3 of execution, described server covers the time of reception that the coupling storing the described equipment transmission received has the message of the IP address of described server.
The beneficial effect of technique scheme:
When the heartbeat message that the technical program can not have timely response server to send at equipment, message moment and prefixed time interval is sent according to the equipment received for the last time by judging unit, obtain the communications status between server and equipment, thus improve the accuracy judging heartbeat break-make.
