With reference to specific embodiments and the drawings, the present invention will be described.
The present invention provides a kind of method of equipment state polling, applied to network management device.Referring to Fig. 1, methods described
Including：
S1, the routing iinformation for obtaining all-network equipment in network management device range of management, and according to the network equipment
Route sensing, which is plucked, selects gateway device.
S2, the keepalive state data for obtaining the gateway device preserved on gateway device and LA Management Room.
If S3, according to the keepalive state data determine that the communications status between the network equipment and gateway device is
Doubtful unreachable, then the network management device is sent to gateway device confirms exceptional instructions, it is desirable to which gateway device is doubted to described
Detected like the unreachable network equipment, with determine the communications status between the network equipment and the gateway device whether be
It is really unreachable.
Need to illustrate, the restriction of step S1-S3 of the present invention and non-invention execution Step Time order, be only
The numbering that description is convenient and is carried out to each step.Meanwhile inventive network management equipment can also obtain range of management in S1
While the routing iinformation of interior all-network equipment, obtain in S2 the keepalive state data of gateway device and LA Management Room and
IP address information of the network equipment etc..
As shown in Fig. 2 for inventive network management equipment under certain application scenarios, institute in its range of management is obtained by S1
There is the routing iinformation example of the network equipment.In one exemplary embodiment of the present invention, the keepalive state data are specially
Location analysis protocol ARP, including the current ageing time of the IP address information of the network equipment and ARP.ARP
（Address Resolution Protocol, address resolution protocol）It is that the IP address of the network equipment is resolved into ethernet mac
Address（Or physical address）Agreement.In actual applications, network management device can pass through Simple Network Management Protocol
SNMP or Command Line Interface CLI mode, obtain the ARP of the network equipment preserved on gateway device.Network management is set
The ARP summary tables that the standby ARP uploaded by collecting all gateway devices is formed on the management network equipment.As shown in figure 3, it is this
Invent under certain application scenarios, the example of the ARP table generated on gateway device.In this application, in order to know that network is set in time
Standby state change, network management device need periodically to obtain the ARP on gateway device.Certain on gateway device
When ARP arrival ageing time cannot still refresh, it will be deleted from the ARP table on the gateway device.It is if old reaching
Recorded and be refreshed before the change time, then recalculate ageing time.
For example, it is assumed that under certain application scenarios, the global ageing time of ARP table of certain gateway device is set as T.ARP table
The current ageing time of ARP corresponding to middle network equipment M is t, and t represents that the list item can also be shown in ARP table（Survival）
Time.Therefore, t is subtracted by T and would know that how long network equipment M does not carry out data interaction with gateway device, set L
=T-t.The status poll cycle I of network management device operating personnel's set device, wherein I are less than T, that is, are set in ARP table
Global digestion period in, it is necessary at least obtain an ARP data.I magnitude is minute rank, network management device operator
Member can choose appropriate numerical value as needed for I.In addition, setting whether Boolean type variable S record network management devices are transmitted across
Confirm that exceptional instructions give the gateway device.Boolean type variable S default value is 0, shows to be directed to network equipment M, the net
Network management equipment is not transmitted across confirming that exceptional instructions to the gateway device, send for network equipment M and confirm to refer to extremely
After order, Boolean type variable S is changed into 1 from 0.
Further, referring to Fig. 4, the whether reachable detailed process of the network equipment is judged for inventive network management equipment
Figure.Comprise the following steps：
S31, judge in polling cycle whether the network equipment with gateway device has data exchange, if it is not, then
Perform S32.
Specifically, I≤L, show that data exchange is not present with gateway device in the network equipment M in polling cycle I；I>
L, show that the network equipment M has data exchange with gateway device in polling cycle I, judges the network equipment and gateway device
Between it is reachable, and update the ARP of the network equipment on gateway device.
The present invention just carries out step S31 only when network equipment M IP address belongs to ARP table in specific implementation and judges behaviour
Make.When network equipment M IP address is not belonging to ARP summary tables, when representing network equipment M IP address free time and exceeding aging
Between, it is removed, directly performs step S32.
S32, confirm that the communications status between the network equipment and gateway device is doubtful unreachable, determine whether net
Whether network management equipment is transmitted across the confirmation exceptional instructions of the network equipment to the gateway device, if it is, 33 are gone to step,
Otherwise, 34 are gone to step；
If S33, network management device are transmitted across the confirmation exceptional instructions of the network equipment to the gateway device, really
It is unreachable and terminate flow to recognize the network equipment.
Specifically, when Boolean type variable S is 1, then the network management device is transmitted across confirming for network equipment M
Exceptional instructions give the gateway device；Conversely, when Boolean type variable S is 0, then the network management device is directed to the network equipment
M is not transmitted across confirming exceptional instructions to the gateway device.
If the confirmation that S34, network management device are not transmitted across the network equipment to the gateway device refers to extremely
Order, the confirmation exceptional instructions of the network equipment are sent to gateway device, it is desirable to which gateway device is to the doubtful unreachable network
Equipment carries out accessibility detection.
If network management device judges not being transmitted across the confirmation exceptional instructions of the network equipment to gateway device,
The reason for data exchange is not present with gateway device in the network equipment in polling cycle, may be due to the network equipment and gateway
Connection status between equipment is unreachable, it is also possible to because the network equipment does not have natively in polling cycle with gateway device
Data need to exchange.Therefore, the network management device needs further to send the confirmation exceptional instructions of the network equipment to institute
State gateway device.Network management device is by confirming exceptional instructions, it is desirable to which gateway device is to the doubtful unreachable network equipment
Carry out accessibility detection, so as to finally determine the doubtful unreachable network equipment and gateway device in polling cycle it is whether original
Need to exchange with regard to no data, so that it is determined that the connection status between the network equipment and gateway device is by doubtful unreachable turn
Be changed into really it is unreachable be still changed into it is reachable.
S35, the result of detection according to gateway device, judge whether really can not between the network equipment and gateway device
Reach.
Network management device, which is sent, confirms that exceptional instructions send according to confirmation exceptional instructions and visited to gateway device, gateway device
Observe and predict text and be changed into 1 from 0 to network equipment M, Boolean type variable S.Now, if state between network equipment M and gateway device
To be really unreachable, then after gateway device sends probe messages to the network equipment, will not certainly will receive to carry out automatic network and set
Standby M detection response message.So, in next polling cycle, will not be deposited between the network equipment M and gateway device
The ARP of network equipment M in data exchange, ARP table will not also be refreshed, and ageing time t will continue to increase.
Next polling cycle come it is interim, L persistently reduce or the ARP directly because of the ageing time T more than overall situation setting and by
Delete.Thus, in next polling cycle, the network management device is it may determine that the network equipment is really can not
Reach；, whereas if it is between the network equipment and gateway device and non-real unreachable, there is no data needs in polling cycle simply
Exchange, then after gateway device sends probe messages to the network equipment, will certainly receive from the network equipment
Detection response message, the ARP of the network equipment on such gateway device will be refreshed.In next polling cycle,
The ARP of the network equipment in ARP table will be refreshed, and so described network management device can is in next poll week
