Maintenance efficiency.
The technical scheme provided in an embodiment of the present invention for realizing two-node cluster hot backup is further retouched below in conjunction with accompanying drawing
State.
As illustrated in fig. 2, it is assumed that backup group includes network equipment A and network equipment B, the network equipment A and B can be respectively two
There are two BAS on individual BRAS, network equipment A（Broadband inserting service, Broadband Access Service）Interface, it is respectively
BAS interfaces 1 and BAS interfaces 2, BAS interfaces 1 connect lower floor network equipment C, and BAS interfaces 2 connect lower floor network equipment D；Network is set
Standby B has two BAS interfaces, is BAS interfaces 3 and BAS interfaces 4 respectively, and BAS interfaces 3 connect lower floor network equipment C, BAS interfaces 4
Connect lower floor network equipment D.Standby system framework with reference to shown in Fig. 2, it is provided in an embodiment of the present invention to realize two-node cluster hot backup
The specific implementation process of processing scheme is as shown in figure 3, BAS interface and network equipment B to be automatically performed in Configuration network device A
On BAS interfaces between main and standby relation and corresponding pretection switch, specifically may comprise steps of：
Step 31, control connection is established, chooses management main equipment and management slave unit；
Specifically, can be in two peer of backup group（That is the network equipment）Between establish TCP connections, and according to priority
Peer one of etc. policy selection is management main equipment, and another is management slave unit, and principal and subordinate's concept here simply manages
Principal and subordinate in meaning, rather than the principal and subordinate of interface；
Corresponding backup group includes two network equipments that can be backed up mutually, i.e. two peer.In the present embodiment, it is false
If specifying network equipment A, network equipment B is management slave unit for management main equipment.
Step 32, the VLAN attributes and local of BAS interfaces are configured（It is local）Attribute；
Specifically, the VLAN attributes of BAS interfaces and local attributes are used for as the foundation for establishing the backup peer itself body,
Wherein, the VLAN attributes of BAS interfaces are used to be used for as the foundation for establishing the backup peer itself body, the local attributes of BAS interfaces
Foundation as the primary interface and spare interface determined in the backup peer itself body.
For example, to BAS interfaces 1 and BAS interfaces 3 are added in backup peer itself body 1, by BAS interfaces 2 and BAS interfaces 4
It is added in backup peer itself body 2, and BAS1 is arranged to the main port in backup peer itself body 1, BAS4 is arranged to back up
Main port in peer-to-peer 2, then the value of BAS interfaces 1 and the VLAN attributes of BAS interfaces 3 can be arranged to 1, by BAS interfaces
The value of the VLAN attributes of 2 and BAS interfaces 4 is arranged to 2, and the value for configuring the local attributes of BAS interfaces 1 and BAS interfaces 4 is 1 (this
In assume that the value of local attributes represents to be arranged to local for 1, represent to be not provided as local for 0), the He of configuration BAS interfaces 2
The value of the local attributes of BAS interfaces 3 is 0.
By the step VLAN accessed for local first can be needed to specify local attributes according to topological structure, to refer to
Certain fixed interface can control lower layer switch to try one's best homonymy as the primary interface in backup peer itself body, based on the local attributes
Access, i.e. the backup peer itself body for a pair of connections（That is the BAS for two network equipments that backup group includes interface）Between it is excellent
The interface that first selection specifies the local attributes is primary interface, wearing between interchanger when reducing U-shaped networking
More flow.
Step 33, manage main equipment and initiate detection of connectivity, to establish backup peer itself body；
In this step, backup peer itself body can be specifically established by way of static detection of connectivity, can also be passed through
The mode of dynamic connectivity detection establishes backup peer itself body, will illustrate respectively below；
（1）The mode of static detection of connectivity establishes backup peer itself body
The management main equipment is according to the value of the VLAN attributes of the BAS interfaces configured in step 32 actively to management slave unit
Initiate detection of connectivity（The detection of connectivity between interface is initiated only in same VLAN according to VLAN configurations）, to detect phase
Connectedness between the BAS interfaces for the management main equipment answered and the BAS interfaces of the management slave unit, and tied according to detection
Fruit establishes backup peer itself body and notices management slave unit, and the backup peer itself body includes the interface that can be backed up mutually and VLAN letters
Breath, such as can be " port（Interface）+ vlan " is right.For example, network equipment A initiates detection of connectivity to network equipment B, specifically
It can be, but not limited to carry BAS interfaces 1 and VLAN1 information in connectivity testing message, obtain network equipment B response,
Network equipment B BAS interfaces 3 are learnt also in VLAN1, so as to establish backup peer itself body 1, the backup peer itself body 1 includes
BAS interfaces 1 and BAS interfaces 3.Afterwards, network equipment A initiates detection of connectivity to network equipment B again, in detection of connectivity report
BAS interfaces 2 and VLAN2 information are carried in text, network equipment B response is obtained, learns that network equipment B BAS interfaces 4 also exist
In VLAN2, so as to establish backup peer itself body 2, the backup peer itself body 2 includes BAS interfaces 2 and BAS interfaces 4.
Main equipment is managed always according to the local attributes of the interface in backup peer itself body, interface rate matching, uplink downlink
The active and standby pass of one or more strategy generating backup peer itself bodies such as flow equalization degree, address pool equilibrium degree and VLAN equal number degree
System（Determine corresponding primary interface and spare interface）And notice management slave unit.For example, when determining primary interface and standby
, can be according to each BAS being configured with above-mentioned steps 32 when the strategy of interface is arranged to need to consider the local attributes of interface
The local attributes of interface determine the main and standby relation of backup peer itself body.
Alternatively, it is also an option that one of backup peer itself body creates standby control company between master-slave equipment is managed
Connect, using the backup link for the TCP connections established as step 31；
（2）The mode of dynamic connectivity detection establishes backup peer itself body
If BAS interfaces VLAN is configured（That is VLAN attributes）For anyother（The configuration of lower layer switch is not known even
The order is then used, represents that any VLAN or QinQ can access）, then need to establish by non-unicast access message Dynamic trigger
Backup peer itself body, the non-unicast access message can be the access protocol association message of user, such as ARP messages or DHCP（Dynamically
Host configuration, Dynamic Host Configuration Protocol）Message etc.；Establish backup peer itself accordingly
The process of body can include：
When management main equipment receives certain VLAN non-unicast access message first, then judge whether the VLAN establishes backup
Peer-to-peer, if the VLAN does not establish backup peer itself body also, initiate detection of connectivity and establish backup peer itself body, connect accordingly
It can also be realized in general character detection process by coordinating with management slave unit detection messages, or, can also be by specially initiating
Detection messages realize；Manage local attribute, interface rate of the main equipment always according to the VLAN on backup peer itself body physical interface
One or more strategy generatings such as matching, uplink downlink flow equalization degree, address pool equilibrium degree and VLAN equal number degree are standby
The main and standby relation of part peer-to-peer simultaneously notices management slave unit；
Further, when management slave unit receives certain VLAN non-unicast access message first, if the VLAN does not have also
Backup peer itself body is established, then initiation connection general character detection on the interface of non-unicast access message is received at this, if detection
As a result it is connection, then shows that corresponding detection of connectivity work can be completed by managing main equipment, and it is non-unicast can now to abandon this
Access message；If detection of connectivity fails, the management slave unit does access to the VLAN and handles and notice management main equipment.
In addition, in the embodiment of the present invention, because topological structure and the VLAN configuration of network may change, thus it is described
Institute can also be initiated according to predetermined time interval periodically for the backup peer itself body having built up by managing main equipment
Link layer connectivity detection is stated, when it is determined that the backup peer itself body failure having built up, then be directed to the backup peer itself body to fail
Interface initiate link layer connectivity detection again, and the interface for the backup peer itself body of the failure establishes new backup
Peer-to-peer, wherein, the backup peer itself body failure refers to that the result backup peer itself body of the detection of connectivity includes
Do not connected between primary interface and spare interface.I.e. described management main equipment can also periodically carry out detection of connectivity to adapt to
The change in topology of lower floor's exchange network, when discovery backup peer itself body is invalid（As three detection cycles are invalid）Afterwards, to original backup pair
The interface included Deng body starts new detection of connectivity process, after new connectedness is detected（Detect new interface with
The orifice that the former backup peer itself body includes）, then the interface message that original backup peer itself body includes is updated（It is i.e. primary
Interface and spare interface information）；Wherein, the change that the length of detection cycle can configure according to the topological structure and VLAN of network
Interval time determines, for example, could be arranged to 60 seconds etc.).
Step 34, the backup peer itself body based on foundation carries out the selection and switching of corresponding primary interface and spare interface；
It is determined that after the primary interface and spare interface that the backup peer itself body includes, the primary interface and spare interface
It can also be changed according to the triggering of event, i.e., former primary interface is likely to become spare interface, and spare interface may also become
Into primary interface.Specifically, first, manage slave unit according to event triggering report etc. approach collect the machine Interface status and
The traffic statistics of outside VLAN granularity are obtained by modes such as active period acquisitions, and are noticed to management main equipment；Afterwards, manage
Main equipment can carry out active and standby selection according to each equipment state, Interface status, uplink downlink flow equalization degree, if having built up
The primary interface that includes of backup peer itself body and spare interface change, then gratuitous ARP packet is sent by new primary interface
Business Stream is oriented to the new primary interface by the lower layer switch of notice（I.e. former spare interface）Interface, with carry out primary interface and
The switching of spare interface；It should be noted that whether because mass flow discrepancy weighs initiate to lead for the backup peer itself body reached the standard grade
Dynamic active-standby switch can be specifically designed to can arrangement（Switch as mass flow discrepancy weighing apparatus degree exceedes predetermined value triggering, and predetermined value is big
It is small configurable）, it is defaulted as not switching, so as to prevent changes in flow rate from causing active and standby frequent switching repeatedly；
Further, when equipment detects opposite equip. DOWN（Failure）When, then by occurrence of equipment level active-standby switch, i.e., not
All spare interfaces of the equipment of failure upgrade to primary interface, and send gratuitous ARP packet and notify lower floor's exchange interface will
Business Stream is oriented to the spare interface in the equipment not failed；Afterwards, after faulty equipment recovers normal, both ends re-establish
Connection, reselect management main equipment and management slave unit and establish corresponding backup peer itself body, synchronous user ID data and
User profile etc., and standby usage interface is elected according to active and standby selection strategy, the primary interface for selecting to determine sends gratuitous ARP report
Business Stream is oriented to the primary interface of the selection determination by the lower layer switch of text notice.
Found automatically according to the configuration of topological structure above-mentioned in the description of the embodiment of the present invention, an emphasis describes
Protection link and the processing procedure for realizing active-standby switch, for the user data backup being related in handoff procedure and BRAS
The back-up processing that issue etc. was distributed and route in location pond uses processing mode of the prior art, therefore does not illustrate.
