Embodiment one
Invention introduces SDN (Software Defined Networks, software defined network) controller, control is utilized
The centralized management ability of device processed, to N:Each equipment (including working equipment and redundance unit) is monitored and managed in 1 network.
On the basis of the network architecture, the present invention proposes a kind of backup method, and this method is by controller by each working equipment group in network
A backup domain is divided into an end to end logic box, and by arbitrary neighborhood working equipment in logic box, by issuing
Hot standby configuration information, configuration work equipment is its affiliated one host apparatus for backing up domain, while another backup belonging to it
The stand-by equipment in domain.When a certain working equipment failure, the working equipment for replacing failure using redundance unit participates in backing up.
It is one embodiment flow chart of backup method of the present invention, the embodiment is from controller side to backing up referring to Fig. 1
Journey is described.
Step 101, the information for the end to end logic box that generation is made up of at least two working equipment.
It is N referring to Fig. 2:1 network diagram, and controller (not shown) has been directed to the N:What 1 network was generated patrols
Ring is collected to show.Between device A~equipment F two layers it is reachable, and set up management passage with controller respectively.Wherein, device A~
Equipment E is working equipment, for carrying customer flow；Equipment F is redundance unit, is not involved in the forwarding of any customer flow.Make
For a kind of embodiment, working equipment can be linked to be logic box, for example, in N by controller according to the reaching the standard grade order of working equipment:1
During network initial launch, controller presets on-line time threshold value, and N is recorded in the on-line time threshold value:Working equipment in 1 network
Reach the standard grade order, if in default on-line time threshold value, device A as shown in Figure 2~equipment E reaches the standard grade successively, then controller will
Device A~equipment E is linked to be logic box end to end shown in Fig. 2, generates the relevant information of logic box, and designated equipment F is superfluous
Remaining equipment.Wherein, the information of logic box includes the device identification of working equipment, on-line time of working equipment etc..Can root
Two equipment adjacent in logic box are determined according to the on-line time of working equipment.
Step 102, divide any two neighboring working equipment on the logic box and belong to same backup domain.
Referring to Fig. 3, example is divided for backup domain.Two working equipments of arbitrary neighborhood are divided into a backup by controller
Domain, for example, device A is adjacent with equipment B, divides device A and belongs to backup domain 1 with equipment B；Equipment B is adjacent with equipment C, and division is set
Standby B and equipment C belongs to backup domain 2；By that analogy.According to the division principle, each working equipment belongs to two backups simultaneously
Domain, for example, equipment B both belongs to backup domain 1, belongs to backup domain 2 again；Equipment C both belongs to backup domain 2, and backup domain 3 is belonged to again.
Step 103, hot standby configuration information is sent to the working equipment.
In this step, controller is set using the interaction protocol (for example, Netconf agreements) between working equipment to work
Preparation send hot standby configuration information, and the hot standby configuration information is used for configuration work equipment in its affiliated first backup domain as primary
Equipment, as stand-by equipment in its affiliated second backup domain, wherein, the first backup domain and the second backup domain are used to distinguish work
Two different backup domains belonging to equipment.In addition, it is ensured that in two working equipments for belonging to same backup domain, a work
Make equipment for host apparatus, another working equipment is that the host apparatus in stand-by equipment, same backup domain is same to stand-by equipment
Walk backup information.Wherein, host apparatus can be with predetermined period to stand-by equipment backed up in synchronization information.
For example, so that controller sends hot standby configuration information to device A as an example, controller configuration facility A is affiliated standby
The host apparatus in part domain 1, is the stand-by equipment in affiliated backup domain 5；Similarly, configuration equipment B sets for affiliated backup the standby of domain 1
It is standby, it is the host apparatus in affiliated backup domain 2, backup information of the device A into equipment B backed up in synchronization domain 1.Set to all working
Standby progress, which is matched somebody with somebody, to be postponed, the active and standby configuration result of each working equipment, as shown in Figure 4.Wherein, " ★ " represents working equipment in its institute

The backup information in domain 1 is backed up to equipment B real-time synchronizations as host apparatus；In backup domain 2, equipment B is used as host apparatus
The backup information in domain 2 is backed up to equipment C real-time synchronizations；By that analogy, the purpose of balanced backup is reached.
It should be added that, on logic box in each working equipment normal course of operation, if there is new working equipment
Reach the standard grade, the working equipment that this is newly reached the standard grade can be added in logic box.
As one embodiment, the working equipment newly reached the standard grade can be added to the work that last in current logic ring is reached the standard grade
Make equipment.Still by taking Fig. 4 as an example, the working equipment that last in current logic ring is reached the standard grade is equipment E, by the work newly reached the standard grade
Equipment W (not shown in Fig. 4) is designated as equipment, hot standby configuration information is sent to equipment W, configuration equipment W is standby for backup domain 5
Equipment, while being the host apparatus of newly-built backup domain 6 (not shown in Fig. 4), notifies that device A is updated to backup the standby of domain 6 and set
It is standby.In backup domain 5, backup informations of the equipment E as host apparatus into equipment W backed up in synchronization domain 5, in backup domain 6, if
Standby backup informations of the W as host apparatus into device A backed up in synchronization domain 6.During equipment W is added, equipment E is not influenceed

Work, controller carries out masterslave switchover, and more new equipment E is the host apparatus in backup domain 4；Further, since backup the primary of domain 3 is set
Standby is equipment C, therefore, and equipment D failure wouldn't influence to back up the work in domain 3.Then, controller sends hot standby match somebody with somebody to equipment F
Confidence ceases, and configuration equipment F is the stand-by equipment in backup domain 4, and configuration equipment F is the stand-by equipment in backup domain 3, and configuration result is as schemed
Shown in 5.Controller notifies backup informations of the equipment C (host apparatus in backup domain 3) into equipment F backed up in synchronization domain 3, notifies
Backup informations of the equipment E (host apparatus in backup domain 4) into equipment F backed up in synchronization domain 4.So far, equipment F replacements are completed to set
Standby D, which is added in logic box, participates in backup.
As it was previously stated, redundance unit is that two be added to the identity of stand-by equipment belonging to the working equipment of cause barrier are standby
In part domain, now, redundance unit carries the back-up jobs in two backup domains, relative to other working equipments on logic box
Backup pressure is larger.Therefore, controller of the present invention notifies the first backup domain (working equipment institute that i.e. cause hinders belonging to redundance unit
First backup domain of category) host apparatus be updated to stand-by equipment, meanwhile, notify that redundance unit is updated to the first backup domain
Host apparatus, with the backup pressure on logic of Equilibrium ring again.Referring to Fig. 5, equipment E (the current backup domains in backup domain 4 are notified
4 host apparatus) stand-by equipment is updated to, notify that equipment F (redundance unit) is updated to back up domain from the stand-by equipment in backup domain 4
4 host apparatus, the active and standby configuration result after renewal is as shown in fig. 6, the logic box reaches that backup is balanced again.
For the working equipment of failure, it can be used after recovering normal as new redundance unit, as shown in fig. 7, equipment
D (working equipment of cause barrier) is used as the redundance unit of the network.
It can be drawn from foregoing description, in the present invention, each working equipment was not only set as host apparatus but also as standby
It is standby, itself work requirements is met as host apparatus, the work with the host apparatus of its Logic adjacent is backed up as stand-by equipment
Information；And N:Redundance unit in 1 network only need to be when there is failure in network, and the working equipment for replacing failure participates in logic
In the backup of ring, the redundance unit need to only possess the hardware configuration of common working equipment, simultaneously as redundance unit is no longer
Undertake the backup pressure of the whole network, therefore, N:The scalability of 1 network is no longer limited.
On the basis of above-described embodiment, controller can be by the information of logic box and hot standby information Store to database
In, database can also be separately positioned in single equipment within one device, this is not limited with controller
