Embodiment
In order to improve the reliability of OpenFlow network, can dispose multiple controller in OpenFlow network, this multiple controller forms a controller cluster.In this controller cluster, a controller is as Leader (leader) controller, and other controller is as Member (member) controller.
When network equipment off-line, need the facility information all controllers in controller cluster all being deleted this network equipment.Based on this, user can issue the order of the facility information deleting the network equipment on Leader controller, by Leader controller after receiving this order, the facility information of this network equipment is deleted from this Leader controller, and the facility information of this network equipment deleted by the Member controller in notification controller cluster, deleted the facility information of this network equipment by the Member controller in controller cluster.Further, in order to all controllers in controller cluster all being deleted the facility information of this network equipment, the embodiment of the present invention can also provide a kind of auto-deleted method of network equipment off-line, and the method can be applied in the SDN comprising the network equipment and multiple controller.In this SDN, deploy multiple controller, and this multiple controller constitutes a controller cluster.Wherein, a Leader controller and multiple Member controller is comprised in this controller cluster.In order to improve the reliability of SDN, a backup controller can also be configured for each controller.
For the backup Leader controller that Leader controller is corresponding, the operating state of backup Leader monitoring control devices Leader controller; When Leader controller did not lose efficacy, backup Leader controller, as the backup of Leader controller, can not replace the work of Leader controller; When Leader controller lost efficacy, backup Leader controller upgraded to new Leader controller, and Leader controller will be replaced to work.Further, for the backup Member controller that Member controller is corresponding, the operating state of backup Member monitoring control devices Member controller; When Member controller did not lose efficacy, backup Member controller, as the backup of Member controller, can not replace the work of Member controller; When Member controller lost efficacy, backup Member controller upgraded to new Member controller, and Member controller will be replaced to work.Further, the network equipment and Member controller and this backup Member controller corresponding to Member controller establish TCP (TransmissionControl Protocol, transmission control protocol) respectively and connect.When Member controller did not lose efficacy, the network equipment communicated with Member controller.When Member controller lost efficacy, the network equipment communicated with the backup Member controller becoming new Member controller.
Take Fig. 1 as the application scenarios schematic diagram of the embodiment of the present invention, in controller cluster, comprise controller 1, controller 2, controller 3, controller 4, controller 5 and controller 6.Wherein, controller 1 is Leader controller, and controller 2 is the backup Leader controller of controller 1.Controller 3 is Member controller, and controller 4 is the backup Member controller of controller 3.Controller 5 is Member controller, and controller 6 is the backup Member controller of controller 5.The network equipment 1 is set up TCP with controller 3 and controller 4 respectively and is connected, and is currently managed by controller 3 pairs of network equipments 1.
As shown in Figure 2, the auto-deleted method of this network equipment off-line specifically comprises the following steps:
Step 201, Member controller sends probe requests thereby message to the network equipment of this Member controller management.If do not receive detection response message in Preset Time, then determine the current off-line of the network equipment.If receive detection response message in Preset Time, then determine that the network equipment is online current.
Wherein, the reason of the current off-line of the network equipment is: the network equipment causes present networks equipment generation off-line due to lower conductance; Or the network equipment causes present networks equipment generation off-line due to network failure.
In the embodiment of the present invention, Member controller periodically (can rule of thumb arrange) can send probe requests thereby message to the network equipment of this Member controller management.Wherein, probe requests thereby message is specifically as follows Echo (loopback) request message, and detection response message is specifically as follows Echo response message.
Such as, controller 3 (i.e. Member controller) sent a probe requests thereby message every 5 seconds to the network equipment 1 (i.e. the network equipment of controller 3 management).If do not receive the detection response message that the network equipment 1 returns in Preset Time (can arrange arbitrarily according to practical experience, as being set to 25 seconds), then the current off-line of the network equipment 1 determined by controller 3.If receive the detection response message that the network equipment 1 returns in Preset Time, then controller 3 determines that the network equipment 1 is current still online.
Step 202, when the current off-line of the network equipment, Member controller sends off-line notification message to Leader controller, receives off-line notification message by Leader controller.Wherein, identification information and the Offtime information of the network equipment of current off-line is carried in this off-line notification message.
Step 203, Leader controller records identification information and the Offtime information of the network equipment carried in off-line notification message in the aging table of pre-configured off-line, and arranges ageing timer for the network equipment.
In the embodiment of the present invention, in off-line notification message, type of message can also be carried, and type of message is specially network equipment off-line type (as the network equipment _ OFFLINE).Leader controller is after receiving the off-line notification message from Member controller, when the type of message finding off-line notification message is network equipment off-line type, in the aging table of pre-configured off-line, then record identification information and the Offtime information of the network equipment carried in off-line notification message, and ageing timer is set for the network equipment.
Such as, when the current off-line of the network equipment 1, controller 3 (i.e. Member controller) sends off-line notification message to controller 1 (i.e. Leader controller), carries the Offtime information (namely controller 3 detects the time of the network equipment 1 off-line) of the identification information of the network equipment 1 and the network equipment 1 in this off-line notification message.Controller 1, after receiving off-line notification message, records the identification information of the network equipment 1 and the Offtime information of the network equipment 1, and arranges ageing timer for the network equipment 1, the aging table of off-line as shown in table 1 in the aging table of pre-configured off-line.
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 the ageing timer time-out that the network equipment is corresponding, Leader controller deletes the facility information of this network equipment from Leader controller, and sends deletion message to all Member controllers in controller cluster.Wherein, the identification information of this network equipment is carried in this deletion message.
Concrete, Leader controller can start a timer, during each timer expiry, and all records in the aging table of Leader controller inquiry off-line.If have ageing timer time-out, then the network equipment of Leader controller determination ageing timer time-out, and delete the facility information of this network equipment from this Leader controller, and send deletion message to all Member controllers in controller cluster.
Such as, when the ageing timer time-out of the network equipment 1 correspondence, controller 1 (Leader controller) determines that the network equipment of ageing timer time-out is the network equipment 1, the facility information of this network equipment 1 is deleted from this controller 1, and send deletion message to all Member controllers (i.e. controller 3, controller 4, controller 5, controller 6) in controller cluster, carry the identification information of the network equipment 1 in this deletion message.In addition, controller 1 can also send to the backup Leader controller (i.e. controller 2) in controller cluster and delete message, carries the identification information of the network equipment 1 in this deletion message.
In the embodiment of the present invention, Leader controller is after deleting the facility information of the network equipment from Leader controller, and Leader controller can also delete record corresponding to this network equipment from the aging table of off-line.Such as, controller 1 is after deleting the facility information of the network equipment 1 from this controller 1, controller 1 can also delete the record of the network equipment 1 correspondence from the aging table of off-line, namely deletes the corresponding relation between the identification information of the network equipment 1, the Offtime information of the network equipment 1 and ageing time.
Step 205, Member controller, after receiving deletion message, utilizes the identification information deleting the network equipment carried in message, deletes the facility information of this network equipment from this Member controller.
Wherein, the type of message deleting message is the network equipment _ deletion.After Member controller receives and deletes message, when finding that type of message is the network equipment _ deletion, then utilize the identification information deleting the network equipment carried in message, directly delete the facility information of this network equipment from this Member controller.
In the embodiment of the present invention, the identification information of the network equipment specifically includes but not limited to one of following or combination in any: UUID (the Universally Unique Identifier of the network equipment, general unique identifier), title, IP address, MAC (Media Access Control, medium access control) address.The facility information of the network equipment specifically includes but not limited to one of following or combination in any: the IP address of the network equipment, bridge (bridge) MAC Address, endpoint of a tunnel IP address (VtepIP), data path mark (DatapathID).
In the embodiment of the present invention, because Leader controller stores the facility information of each network equipment in internal memory, therefore, when Leader controller needs to delete the facility information of the network equipment from Leader controller, Leader controller is all devices information of deleting this network equipment from internal memory, as the IP address, bridge MAC Address, endpoint of a tunnel IP address, data path mark etc. of this network equipment.Such as, when Leader controller in internal memory with all devices information of mode storage networking device of hash table time, all devices information of this network equipment by same for correspondence hash value, the hash value that the IP address as equipment Network Based is determined.In the case, when needing to delete all devices information of the network equipment from internal memory, first obtaining the IP address of this network equipment, and determining the hash value that the IP address of this network equipment is corresponding.Afterwards, Leader controller obtains all devices information corresponding to this hash value from internal memory, and from internal memory, delete all devices information corresponding to this hash value.In like manner, the process that Member controller deletes the facility information of the network equipment from this Member controller is identical with the process that Leader controller deletes the facility information of the network equipment from this Leader controller, repeats no longer in detail in the embodiment of the present invention to this.
In the embodiment of the present invention, Member controller is after sending probe requests thereby message to the network equipment of this Member controller management, if receive detection response message in Preset Time, if sent the off-line notification message for this network equipment to Leader controller before Member controller, then the Member controller determination network equipment is current reaches the standard grade again, and send to Leader controller notification message of reaching the standard grade, carry identification information and the on-line time information of the current network equipment of again reaching the standard grade in this notification message of reaching the standard grade.Further, Leader controller is after receiving the notification message of reaching the standard grade from Member controller, by the aging table of identification information-enquiry off-line of the current network equipment of again reaching the standard grade, if there is the identification information of the current network equipment of again reaching the standard grade in the aging table of this off-line, then Leader controller needs from the aging table of off-line, delete record corresponding to the current network equipment of again reaching the standard grade.
In the embodiment of the present invention, in notification message of reaching the standard grade, type of message can also be carried, and type of message is specially the network equipment reaches the standard grade type (as the network equipment _ ONLINE).Leader controller is after receiving the notification message of reaching the standard grade from Member controller, when the type of message of notification message of finding to reach the standard grade be the network equipment reach the standard grade type time, then by the aging table of identification information-enquiry off-line of the current network equipment of again reaching the standard grade, if there is the identification information of the current network equipment of again reaching the standard grade in the aging table of this off-line, then Leader controller needs from the aging table of off-line, delete record corresponding to the current network equipment of again reaching the standard grade.
Such as, when controller 3 (i.e. Member controller) receives the detection response message that the network equipment 1 returns in Preset Time, if sent the off-line notification message for this network equipment 1 to controller 1 (i.e. Leader controller) before controller 3, then controller 3 is determined that the network equipment 1 is current and is again reached the standard grade, and send to controller 1 notification message of reaching the standard grade, the identification information of the current network equipment 1 of again reaching the standard grade and the on-line time information (namely controller 3 detects the time that the network equipment 1 is reached the standard grade again) of the network equipment 1 is carried in this notification message of reaching the standard grade.Controller 1 is after receiving notification message of reaching the standard grade, by the aging table of identification information-enquiry off-line of the current network equipment 1 of again reaching the standard grade, if there is the identification information of the current network equipment 1 of again reaching the standard grade in the aging table of this off-line, then controller 1 needs the record deleting the current network equipment 1 correspondence of again reaching the standard grade from the aging table of off-line, namely deletes the corresponding relation between the identification information of the network equipment 1, the Offtime information of the network equipment 1 and ageing time.
In the embodiment of the present invention, for the aging table of the off-line that Leader controller is safeguarded, aging for off-line table regularly can also be sent to backup Leader controller by Leader controller, to carry out back-up processing to the aging table of off-line on backup Leader controller, thus improve the reliability of the aging table maintenance of off-line.Further, for the aging table of the off-line that Leader controller is safeguarded, when the content of the aging table of off-line changes, Leader controller can also be real-time aging for off-line table is sent to backup Leader controller, to carry out back-up processing to the aging table of off-line on backup Leader controller.
