TCP (Transmission Control Protocol, transmission control protocol) connections.When Member controllers do not fail, net
Network equipment is communicated with Member controllers.When Member controllers fail, the network equipment as new Member with controlling
The backup Member controllers of device processed are communicated.
Application scenarios schematic diagram using Fig. 1 as the embodiment of the present invention, include in controller cluster controller 1, controller 2,
Controller 3, controller 4, controller 5 and controller 6.Wherein, controller 1 is Leader controllers, and controller 2 is controller 1
Backup Leader controllers.Controller 3 is Member controllers, and controller 4 is the backup Member controllers of controller 3.
Controller 5 is Member controllers, and controller 6 is the backup Member controllers of controller 5.The network equipment 1 respectively with control
Device 3 is established TCP with controller 4 and connected, and currently the network equipment 1 is managed by controller 3.
As shown in Fig. 2 the offline auto-deleted method of the network equipment specifically includes following steps：
Step 201, Member controllers send the probe requests message to the network equipment of this Member controller managements.Such as
Fruit does not receive detection response message in preset time, it is determined that the network equipment currently has been off.If in preset time
Receive detection response message, it is determined that the network equipment is currently online.
Wherein, the reason for network equipment currently has been off be：The network equipment causes present networks equipment to occur due to lower conductance
Offline；Or the network equipment is offline because network failure causes present networks equipment to occur.
In the embodiment of the present invention, Member controllers periodically (can rule of thumb set) can control to this Member
The network equipment of device management sends the probe requests message.Wherein, the probe requests message is specifically as follows Echo (loopback) requests and disappeared
Breath, detection response message are specifically as follows Echo response messages.
For example, every 5 seconds, to the network equipment 1, (network that i.e. controller 3 manages was set controller 3 (i.e. Member controllers)
It is standby) send a probe requests message.If (it can be arbitrarily configured according to practical experience, be such as arranged in preset time
25 seconds) in do not receive the network equipment 1 return detection response message, then controller 3 determine the network equipment 1 currently have been off.
If receiving the detection response message of the return of the network equipment 1 in preset time, controller 3 determines that the network equipment 1 is current still
It is so online.
Step 202, when the network equipment currently has been off, Member controllers send offline logical to Leader controllers
Know message, offline notification message is received by Leader controllers.Wherein, carry in the offline notification message and currently have been off
The network equipment identification information and Offtime information.
Step 203, Leader controllers record what is carried in offline notification message in the offline aging table being pre-configured with
The identification information and Offtime information of the network equipment, and ageing timer is set for the network equipment.
In the embodiment of the present invention, type of message can also be carried in offline notification message, and type of message is specially network
Equipment off-line type (such as network equipment _ OFFLINE).Leader controllers are receiving leading to offline from Member controllers
After knowing message, when the type of message for finding offline notification message for the network equipment offline type when, then be pre-configured with from
The identification information and Offtime information of the network equipment carried in offline notification message are recorded in line aging table, and is set for network
It is standby that ageing timer is set.
For example, when the network equipment 1 currently has been off, controller 3 (i.e. Member controllers) to controller 1 (i.e.
Leader controllers) offline notification message is sent, the identification information and network of the network equipment 1 are carried in the offline notification message
The Offtime information of equipment 1 (i.e. controller 3 detects time that the network equipment 1 has been off).Controller 1 receive from
After line notification message, the identification information and the network equipment 1 of the network equipment 1 are recorded in the offline aging table being pre-configured with
Offtime information, and ageing timer, offline aging table as shown in table 1 are set for the network equipment 1.
Table 1
| Identification information | Offtime information | Ageing timer |
| The identification information of the network equipment 1 | The Offtime information of the network equipment 1 | Ageing time |
Step 204, when ageing timer time-out corresponding to the network equipment, Leader controllers are from Leader controllers
The facility information of the network equipment is deleted, and all Member controllers into controller cluster send and delete message.Wherein,
The identification information of the network equipment is carried in the deletion message.
Specifically, Leader controllers can start a timer, during each timer expiry, Leader controllers are looked into
Ask all records in offline aging table.If ageing timer time-out, then Leader controllers determine that ageing timer surpasses
When the network equipment, and delete from this Leader controllers the facility information of the network equipment, and into controller cluster
All Member controllers, which are sent, deletes message.
For example, when ageing timer time-out corresponding to the network equipment 1, controller 1 (Leader controllers) determines aging
The network equipment of timer expiry is the network equipment 1, deletes the facility information of the network equipment 1 from this controller 1, and to control
All Member controllers (i.e. controller 3, controller 4, controller 5, controller 6) in device cluster processed, which are sent, deletes message,
The identification information of the network equipment 1 is carried in the deletion message.In addition, controller 1 can also be to the backup in controller cluster
Leader controllers (i.e. controller 2), which are sent, deletes message, and the identification information of the network equipment 1 is carried in the deletion message.
In the embodiment of the present invention, Leader controllers from Leader controllers delete the network equipment facility information it
Afterwards, Leader controllers can also delete record corresponding to the network equipment from offline aging table.For example, controller 1 from
After the facility information that the network equipment 1 is deleted on this controller 1, controller 1 can also delete network from offline aging table and set
Recorded corresponding to standby 1, that is, delete the identification information of the network equipment 1, the Offtime information of the network equipment 1 and ageing time it
Between corresponding relation.
Step 205, Member controllers are after receiving and deleting message, using deleting the network equipment that is carried in message
Identification information, the facility information of the network equipment is deleted from this Member controllers.
Wherein, the type of message for deleting message is the network equipment _ deletion.After Member controllers receive deletion message,
When it is the network equipment _ deletion to find type of message, then the identification information of the network equipment carried using deleting in message, directly
The facility information of the network equipment is deleted from this Member controllers.

Newly reach the standard grade, and notification message of reaching the standard grade is sent to Leader controllers, carry what is currently reached the standard grade again in the notification message of reaching the standard grade
The identification information and on-line time information of the network equipment.Further, Leader controllers are being received from Member controls
After the notification message of reaching the standard grade of device, the offline aging table of identification information-enquiry of the network equipment by currently reaching the standard grade again, if
The identification information of the current network equipment reached the standard grade again in the offline aging table be present, then Leader controllers are needed from offline old
Delete in change table and recorded corresponding to the current network equipment reached the standard grade again.
In the embodiment of the present invention, type of message can also be carried in notification message of reaching the standard grade, and type of message is specially network
Equipment is reached the standard grade type (such as network equipment _ ONLINE).Leader controllers receive it is logical from reaching the standard grade for Member controllers
After knowing message, when find reach the standard grade notification message type of message for the network equipment reach the standard grade type when, then by currently again on
The offline aging table of identification information-enquiry of the network equipment of line, if the current network reached the standard grade again in the offline aging table be present
The identification information of equipment, then the current network equipment reached the standard grade again of Leader controllers needs deletion from offline aging table is corresponding
Record.
For example, controller 3 (i.e. Member controllers) receives the probe response report of the return of the network equipment 1 in preset time
Wen Shi, if warp-wise controller 1 (i.e. Leader controllers) is transmitted across for the offline of the network equipment 1 before controller 3
Notification message, then controller 3 determines that the network equipment 1 has currently been reached the standard grade again, and sends notification message of reaching the standard grade to controller 1,
The current identification information of the network equipment 1 reached the standard grade again and the on-line time of the network equipment 1 are carried in the notification message of reaching the standard grade
Information (i.e. controller 3 detects time that the network equipment 1 is reached the standard grade again).Controller 1 after notification message of reaching the standard grade is received,
The offline aging table of identification information-enquiry of the network equipment 1 by currently reaching the standard grade again, work as if existed in the offline aging table
The identification information of the preceding network equipment 1 reached the standard grade again, then controller 1 needs to delete from offline aging table current reaches the standard grade again
Recorded corresponding to the network equipment 1, that is, delete the identification information of the network equipment 1, the Offtime information of the network equipment 1 and aging
Corresponding relation between time.
