The technical scheme that the realizes two-node cluster hot backup embodiment of the present invention being provided below in conjunction with accompanying drawing is further described.
As shown in Figure 2, suppose that backup group comprises network equipment A and network equipment B, network equipment A and B can be respectively two BRAS, on network equipment A, there are two BAS(broadband inserting services, Broadband Access Service) interface, be respectively BAS interface 1 and BAS interface 2, BAS interface 1 connects the network equipment C of lower floor, and BAS interface 2 connects the network equipment D of lower floor; Network equipment B has two BAS interfaces, is respectively BAS interface 3 and BAS interface 4, and BAS interface 3 connects the network equipment C of lower floor, and BAS interface 4 connects the network equipment D of lower floor.In conjunction with the standby system framework shown in Fig. 2; the specific implementation process of the processing scheme of two-node cluster hot backup that what the embodiment of the present invention provided realize as shown in Figure 3; switch with the main and standby relation and the corresponding protection that automatically complete between the BAS interface on BAS interface and the network equipment B on configure network devices A, specifically can comprise the following steps:
Step 31, sets up control connection, chooses management main equipment and management from equipment;
Particularly, can be the network equipment at two of a backup group peer() between set up TCP connect, and according to one of them peer of the policy selection such as priority for management main equipment, another for management from equipment, principal and subordinate's concept here is just managed the principal and subordinate in meaning, instead of the principal and subordinate of interface;
Corresponding backup group comprises two network equipments that can back up mutually, i.e. two peer.In the present embodiment, suppose that specified network device A is for management main equipment, network equipment B is for management is from equipment.
Step 32, VLAN attribute and local(this locality of configuration BAS interface) attribute;
Particularly, the VLAN attribute of BAS interface and local attribute are for the foundation as setting up described backup peer itself body, wherein, the VLAN attribute of BAS interface is for the foundation as setting up described backup peer itself body, and the local attribute of BAS interface is for the primary interface as definite described backup peer itself body and the foundation of spare interface.
For example, if BAS interface 1 and BAS interface 3 will be joined in backup peer itself body 1, BAS interface 2 and BAS interface 4 are joined in backup peer itself body 2, and BAS1 is set to the main port in backup peer itself body 1, BAS4 is set to the main port in backup peer itself body 2, can BAS interface 1 and the value of the VLAN attribute of BAS interface 3 be set to 1, the value of the VLAN attribute of BAS interface 2 and BAS interface 4 is set to 2, the value of the local attribute of configuration BAS interface 1 and BAS interface 4 is that 1 (value of supposing local attribute is here that 1 expression is set to local, be that 0 expression is not set to local), the value of the local attribute of configuration BAS interface 2 and BAS interface 3 is 0.
Can need to specify local attribute for the VLAN of local first access according to topological structure by this step, to specify certain interface as the primary interface in backup peer itself body, can control the try one's best homonymy access of lower layer switch based on this local attribute, to select to have specified the interface of described local attribute be primary interface for preferential between the backup peer itself body of a pair of connection (being the interface of the BAS of two network equipments comprising of backup group), to reduce in the situations such as U-shaped networking the flow that passes through between switch.
Step 33, management main equipment is initiated detection of connectivity, to set up backup peer itself body;
In this step, specifically can set up backup peer itself body by the mode of static detection of connectivity, the mode that also can detect by dynamic connectivity is set up backup peer itself body, will describe respectively below;
(1) mode of static detection of connectivity is set up backup peer itself body
Described management main equipment is initiatively initiated detection of connectivity (the detection of connectivity between interface is only initiated in configuration in same VLAN according to VLAN) according to the value of the VLAN attribute of the BAS interface of configuration in step 32 to management from equipment, to detect the BAS interface of corresponding described management main equipment and described management from the connectedness between the BAS interface of equipment, and set up backup peer itself body and notice management from equipment according to testing result, described backup peer itself body comprises interface and the vlan information that can back up mutually, can be for example " port(interface)+vlan " right.For example, network equipment A initiates detection of connectivity to network equipment B, specifically can be, but not limited to carry the information of BAS interface 1 and VLAN1 in connectivity testing message, obtain the response of network equipment B, learn that the BAS interface 3 of network equipment B is also in VLAN1, thereby set up backup peer itself body 1, described backup peer itself body 1 comprises BAS interface 1 and BAS interface 3.Afterwards, network equipment A initiates detection of connectivity to network equipment B again, in connectivity testing message, carry the information of BAS interface 2 and VLAN2, obtain the response of network equipment B, learn that the BAS interface 4 of network equipment B is also in VLAN2, thereby set up backup peer itself body 2, described backup peer itself body 2 comprises BAS interface 2 and BAS interface 4.
Management main equipment also generates the main and standby relation (determining corresponding primary interface and spare interface) of backup peer itself body and notices management from equipment according to the one or more strategy such as the local attribute of the interface in backup peer itself body, interface rate coupling, uplink downlink flow equalization degree, address pool equilibrium degree and VLAN quantity equilibrium degree.For example, when determining that the strategy of primary interface and spare interface is set to consider the local attribute of interface, can determine according to the local attribute of the each BAS interface having configured in above-mentioned steps 32 main and standby relation of backup peer itself body.
Alternatively, between management master-slave equipment, can also select one of them backup peer itself body to create control connection for subsequent use, the backup link connecting using the TCP setting up as step 31;
(2) mode that dynamic connectivity detects is set up backup peer itself body
If BAS interface VLAN configuration (being VLAN attribute), for the configuration of the even unclear lower layer switch of anyother(, is used this order, represent that any VLAN or QinQ can be accessed by), need to set up backup peer itself body by non-unicast access message Dynamic trigger, this non-unicast access message can be user's access protocol association message, as ARP message or DHCP(DHCP, Dynamic Host Configuration Protocol) message etc.; The process of setting up accordingly backup peer itself body can comprise:
In the time that management main equipment is received the non-unicast access message of certain VLAN first, judge whether this VLAN sets up backup peer itself body, if this VLAN does not also set up backup peer itself body, initiate detection of connectivity and set up backup peer itself body, also can be by coordinating realization with management from equipment Inspection message in corresponding detection of connectivity process, or, also can realize by the special detection messages of initiating; Management main equipment also generates the main and standby relation of backup peer itself body and notices management from equipment according to the one or more strategy such as the local attribute of the VLAN on backup peer itself body physical interface, interface rate coupling, uplink downlink flow equalization degree, address pool equilibrium degree and VLAN quantity equilibrium degree;
Further, in the time that management is received the non-unicast access message of certain VLAN from device first, if this VLAN does not also set up backup peer itself body, receive and on the interface of non-unicast access message, initiate to connect the general character and detect at this, if testing result is for being communicated with, show to manage main equipment and can complete corresponding detection of connectivity work, now can abandon this non-unicast access message; If detection of connectivity failure, this management is done access from equipment to this VLAN and is processed and notice management main equipment.
In addition, in the embodiment of the present invention, because topology of networks and VLAN configuration may change, therefore described management main equipment can also be according to predetermined time interval, periodically initiating described link layer connectivity for the described backup peer itself body of having set up detects, the backup peer itself body set up lost efficacy described in determine, again initiating described link layer connectivity for the interface of the backup peer itself body losing efficacy detects, and set up new backup peer itself body for the interface of the backup peer itself body of described inefficacy, wherein, the lost efficacy result that refers to described detection of connectivity of described backup peer itself body is not to be communicated with between the primary interface that comprises of described backup peer itself body and spare interface.Be that described management main equipment can also periodically carry out detection of connectivity to adapt to the change in topology of lower floor's switching network, when finding after backup peer itself body invalid (as invalid in three sense cycle), the interface that former backup peer itself body is comprised starts new detection of connectivity process, (detect that new interface is communicated with the interface that described former backup peer itself body comprises) when detecting after new connectedness, upgrade the interface message (being primary interface and spare interface information) that described original backup peer itself body comprises; Wherein, the length of sense cycle can be determined according to the change interval time of topology of networks and VLAN configuration, for example, can be set to 60 seconds etc.).
Step 34, the backup peer itself body based on setting up carries out selection and the switching of corresponding primary interface and spare interface;
Determining that after the primary interface and spare interface that described backup peer itself body comprises, described primary interface and spare interface can also change according to the triggering of event, former primary interface may become spare interface, and spare interface also may become primary interface.Particularly, first, management is collected the Interface status of the machine and the traffic statistics that mode is obtained outside VLAN granularity such as is obtained by the active cycle according to approach such as Event triggered report from equipment, and notices to management main equipment; Afterwards, management main equipment can carry out active and standby selection according to each equipment state, Interface status, uplink downlink flow equalization degree, if primary interface and spare interface that the backup peer itself body of having set up comprises change, send the lower layer switch of gratuitous ARP packet notice by Business Stream described new primary interface (the being former spare interface) interface that leads, to carry out the switching of primary interface and spare interface by new primary interface; It should be noted that, whether initiating initiatively active and standby switching because of mass flow discrepancy weighing apparatus for the backup peer itself body of having reached the standard grade specifically can be designed to arrangement (to switch as mass flow discrepancy weighing apparatus degree exceedes predetermined value triggering, and predetermined value size is configurable), be defaulted as and do not switch, thereby can prevent that changes in flow rate from causing active and standby frequently switching repeatedly;
Further, when equipment Inspection was lost efficacy to opposite equip. DOWN() time, will there is the active and standby switching of device level, all spare interface of the equipment not losing efficacy upgrade to primary interface, and send the described spare interface that the exchange interface of gratuitous ARP packet notice lower floor is led Business Stream in the equipment not losing efficacy; Afterwards, after faulty equipment recovers normally, two ends re-establish connection, reselect management main equipment and management from equipment and set up corresponding backup peer itself body, simultaneous user's Backup Data and user profile etc., and according to active and standby selection strategy election standby usage interface, the primary interface of selecting to determine sends the lower layer switch of gratuitous ARP packet notice by the Business Stream primary interface that described selection determines that leads.
In the above-mentioned description for the embodiment of the present invention; emphasis has been described according to the configuration of topological structure and has automatically been found to protect link and realize the processing procedure of active and standby switching; back-up processing for the user data backup relating in handoff procedure and the distribution of BRAS address pool and route issue etc. adopts processing mode of the prior art, therefore specify.
