Abstract
The invention discloses a load balancing method and equipment in a VRRP scene. The method and the equipment can effectively solve the problem that outlet bandwidth load is unbalanced after the down link of a router becomes abnormal under the condition of double-outlet networking of a small data center, and can guarantee the load balancing of outlet bandwidth and improve the utilization rate and the service quality of outlet bandwidth of users.
Description
Technical field
The present invention relates to communication technical field, load-balancing method and equipment in particularly a kind of VRRP scene.
Background technology
Have the target that a large amount of visit capacities and user are the information service providers, but a large amount of visits brings white elephant can for the network of data center.
Along with the user number of Internet application service constantly increases, the network of data center becomes and sinks beneath one's burden, and especially the egress router forwarding performance of data center network and outlet bandwidth all face great challenge.
Simultaneously, the reliability of data center is the problem that the user is concerned about most.
In order to improve the reliability of data center, the redundancy that the designing requirement of data center network is high.Promptly all network nodes all must guarantee to have the redundant node of a symmetry; All links all must guarantee to have the redundant link of a symmetry; So that when a node or a link break down; Network can switch to flow on another symmetry redundant node or link fast, reduces time of service interruption, improves the reliability of system.
Network dual exit is present the most frequently used a kind of scheme that improves data center's Egress node and link reliability.
Network dual exit can be twice the outlet bandwidth expansion, and the egress router forwarding performance doubles.Simultaneously, also can realize the Redundancy Design of Egress node and link.
Network dual exit mainly contains two kinds at present:
A kind of is that two links of outlet are connected respectively to the different ISP of operator;
Another kind then exports two links and is connected to the same ISP of operator.
Latter event is the main research scene of the present invention.
It is less that so-called small-sized data center refers to the server scale, the relatively simple data center of network configuration.
In the prior art, the sketch map of small-sized data center framework is as shown in Figure 1.
There is an apparent in view characteristic in small-sized data center, is exactly owing to the server small scale, also can be very strict to cost control.Usually can use comparatively cheap switch, and in order to reduce the quantity of switch, usually can be with core, converge, the switch of many levels such as access is integrated on the switch of same aspect.
That is to say, use two cheap Layer 2 switch simultaneously as core, converge, access switch uses, router, fire compartment wall and server all directly are linked on the core switch, divide through the different network segments.
From in logic, just be equivalent to fire compartment wall direct-connected below egress router.
In order to guarantee the load balancing of the two outlets of small-sized data center, prior art mainly contains dual mode: equal-cost route scheme and Virtual Router Redundancy Protocol (Virtual Router Redundancy Protocol, VRRP) scheme.
As shown in Figure 2, be the structural representation of the pairing network system of a kind of equal-cost route scheme in the prior art.
Slave firewall to two egress router disposes two equal-cost routes, guarantees that uplink traffic can be distributed on two outbounds uniformly.
The advantage of equal-cost route scheme is that configuration is simple, and two outlet load balancing effect is fine.
As shown in Figure 3, be the structural representation of the pairing network system of a kind of VRRP scheme in the prior art.
Configuration VRRP group between two egress routers.
Can be distributed to uniformly on two outbounds in order to ensure uplink traffic, can dispose 4 groups of VRRP usually.
VRRP group 1 (M1 and S1) and VRRP organize 3 (M3 and S3) on path L1 and L2, and active and standby each other.
VRRP group 2 (M2 and S2) and VRRP organize 4 (M4 and S4) on path L3 and L4, and active and standby each other.
The advantage of this scheme is that two outlet load balancing effects are fine.
In realizing process of the present invention, the inventor finds that there is following problem at least in prior art:
The shortcoming of equal-cost route scheme is: because Layer 2 switch is placed between fire compartment wall and the router; So when the link between egress router and the switch occurs when unusual; Fire compartment wall can't this change in topology of perception; So adjustment can not appear in the equal-cost route on the fire compartment wall, uplink traffic remains generally removes router-A, and second half removes router B.Like this, can cause having half the flow to be abandoned, cause serious service disconnection by switch.
The shortcoming of VRRP scheme is: when the link between egress router and the switch occurs when unusual, the VRRP group is switched, and guarantees that flow does not interrupt.But at this moment all flows all can pass through a link, and another link then is in idle state, thereby cause the valuable wide area network bandwidth resources of user to have only 50% utilance.

Embodiment
Under the two outlet of existing small-sized data center network networking; The VRRP scheme is switched the problem that causes half outlet bandwidth resources idle; The present invention proposes a kind of method of between the VRRP group, carrying out interface principal and subordinate switching flexibly; Can remedy the deficiency of traditional VRRP scheme, use outlet bandwidth fully, guarantee two outlet load balancing simultaneously.
Core concept of the present invention is, at the interface of same egress router between two different VRRP, by be in the VRRP group Slave (from) interface of state initiatively another VRRP of Track (detections) organize the Interface status that is in Master (master) state.If find to be occurred unusual by the main interface of Track; The interface that then is in the Slave state in this VRRP group can initiatively improve the VRRP priority of self, also successfully upgrades to Master with the main interface competition Master that is positioned at the same VRRP group on other egress routers.
The VRRP group that so just can guarantee the both sides router is intersected switching simultaneously, the egress router load balancing.
Based on above-mentioned technical thought; The present invention proposes the load-balancing method in a kind of VRRP scene; Be applied to comprise that in the network system of at least two routers, wherein each router comprises two interfaces at least, belong in the different VRRP groups; Through being provided with in advance; Makes to form between the interface that adheres to two different VRRP groups on the same router separately and bind the relation of detection, and an interface in two interfaces of said each router is the main interface of this interface place VRRP group, another interface for this interface belong to that another VRRP organizes from interface.
Concrete, the schematic flow sheet of said load-balancing method is as shown in Figure 4, specifically may further comprise the steps:
Step S401, each router are provided with the state of each interface, and guarantee to have master and slave two interfaces that belong to different VRRP groups on the same router at least, and the master and slave interface of same VRRP group is on the different routers.
In the present embodiment, to comprise that at least two VRRP group is that example describes, router-A is provided with the main interface M1 in the VRRP group 1, in the VRRP group 2 from interface S2, router B is provided with the main interface M2 in the VRRP group 2, be provided with VRRP group 1 from interface S1.
In addition, in embodiments of the present invention, also needing further be each master and slave interface setting initial priority parameter, and when main interface is unusual, constitutes the upgrading numerical value from the priority parameters of interface increase of binding relationship with it.
Step S402, on same router, will adhere to the main interface of two different VRRP groups separately and be arranged to binding relationship from interface, and detecting on this router and the state of main interface that should constitute another VRRP group of binding relationship from interface from interface through a VRRP group.
In this step; Be actually by accomplishing state-detection from interface (second interface of each router) the main interface (first interface of each router) of VRRP group 2 or VRRP group 1 as VRRP group 1 or VRRP group 2; Because above-mentioned detection interface and interface to be detected is positioned at same router, above-mentioned detection is accomplished.
In the present embodiment, by the main interface M2 from interface S 1 detection VRRP group 2 of VRRP group 1, by the main interface M1 from interface S2 detection VRRP group 1 of VRRP group 2.
When router through detecting from interface and should constituting main interface of binding relationship when unusual from interface, then with this main interface change to this correspondence VRRP group from interface, and execution in step S403;
When router through not detecting from interface and should constituting the main interface of binding relationship when unusual from interface, return step S402 and continue to detect.
Step S403, the said priority from interface of adjustment make this change to the main interface of the VRRP group at place from interface, bear this flow load from VRRP group at interface place.

When router through detect from interface with should cause unusually from a certain VRRP group main interface that interface constitutes binding relationship this main interface change to the place the VRRP group from interface the time; Router is according to predetermined policy; The upgrading numerical value that the priority parameters value from interface of increase or minimizing and this main interface formation binding relationship is preset; Make the pairing priority-level of this priority parameters be higher than the pairing priority-level of priority parameters of this initial main interface from the VRRP group at interface place, and then competition become this main interface from the VRRP group at interface place from interface.
It is to be noted; Above-mentioned upgrading numerical value is that a pre-set priority parameters changes value; Increase or minimizing through this priority parameters variable quantity; Can make the pairing priority-level of the priority parameters from interface in the same VRRP group be higher than the pairing priority-level of priority parameters of the initial main interface this VRRP group; Thereby accomplish the switching from interface and main interface, every value that can reach above-mentioned technique effect all can be used as above-mentioned upgrading numerical value, and the variation of concrete numerical values recited can't influence protection scope of the present invention.
And, in order to simplify flow process is set, under initial condition, the priority parameters value that the main interface in each VRRP group can be set equates that all the priority parameters value from interface in each VRRP group all equates.
Based on the setting of above-mentioned priority parameters, each router can be realized the adjustment of Interface status through the priority parameters of revising each interface, thereby, accomplish dynamic equalization to load.
In order further to set forth technological thought of the present invention, combine concrete application scenarios at present, technical scheme of the present invention is described.
In technical scheme of the present invention, the interface that is arranged in router can be that different physical interfaces also can be the logic interfacing that each physical interface is positioned at different VLAN, below, just technical scheme of the present invention is described through concrete interface type.

Need further be pointed out that; Above-mentioned is the simplest a kind of embodiment of technical scheme of the present invention; The first above-mentioned interface and second interface can be two physical interfaces independently; Also can be in same physical interface through the logic interfacing that different VLAN realizes is set, the variation of physical interface type can't influence protection scope of the present invention.
In concrete application scenarios; In fact can also realize through the pattern of four groups of VRRP groups as shown in Figure 3; Under 4 VRRP group scenes; Principle under the principle of the realization flow of present technique scheme and aforementioned 2 VRRP group scene is basic identical, indicate active and standbyly each other, and carries out the intersection detection of downlink status between the different VRRP groups in each egress router in system.
Particularly, to VRRP scene shown in Figure 3, the present invention does following the setting earlier:
A, organize according to two VRRP of following policy configurations on the L3 of the path of the path of RouterA L1 and RouterB:
Wherein, VRRP group 1 interface with RouterA is Master Interface 1 (main interface 1, the back literary composition is called for short M1), is Slave interface 1 (from interface 1, the back literary composition is called for short S1) with the interface of RouterB;
B, organize according to two VRRP of following policy configurations on the L4 of the path of the path of RouterA L2 and RouterB:
Wherein, VRRP group 2 interfaces with RouterA are Master Interface 2 (main interface 2, the back literary composition is called for short M2), are Slave interface 2 (from interface 2, the back literary composition is called for short S2) with the interface of RouterB;
C, system is configured to 100 with the priority parameters unification of each Master Interface, and the priority parameters unification of each Slave interface is configured to 70.
Wherein, it is pointed out that above-mentioned numerical value is just explained for ease and the example that provides can be adjusted as required in practical application, the variation of concrete numerical value does not influence protection scope of the present invention.
D, set up interface and bind testing mechanism in each router:
Set the M1 of the S2 detection VRRP group 1 on the RouterA, if M1 occurs unusual (change to from interface or link transmission and interruption occurs), then the priority parameters of S2 increases by 50 (reaching 120).
Set the M4 of the S3 detection VRRP group 4 on the RouterA, if M4 occurs unusual (change to from interface or link transmission and interruption occurs), then the priority parameters of S3 increases by 50 (reaching 120).
Set the M2 of the S1 detection VRRP group 2 on the RouterB, if M2 occurs unusual (change to from interface or link transmission and interruption occurs), then the priority parameters of S1 increases by 50 (reaching 120).
Set the M3 of the S4 detection VRRP group 3 on the RouterB, if M3 occurs unusual (change to from interface or link transmission and interruption occurs), then the priority parameters of S4 increases by 50 (reaching 120).

As shown in Figure 6, when the M1 of RouterA occurs when unusual, the switching of active and standby interface takes place in the VRRP group 1:
Interface among the RouterB becomes M1 by becoming main interface from Interface status;
Interface among the RouterA is from interface from the main interface Status Change, becomes S1.
After VRRP group 1 is switched; According to prior art; The Master Interface of VRRP group 1, VRRP group 2 and VRRP group 3 all is positioned at RouterB, has only the Master Interface of VRRP group 4 to be positioned at RouterA, causes the flow of two outlet RouterA and RouterB very unbalanced; Directly consequence is exactly that an outlet bandwidth is not enough, and another outlet bandwidth leaves unused.
Adopt the present invention program, because the S2 on RouterA detects the state of the former M1 of VRRP group 1, so when the former M1 among the RouterA takes place when unusual, then the priority parameters of S2 increases by 50 (reaching 120).
In such cases, the S2 priority of current VRRP group 2 is 120, and the priority of M2 is 100, is higher than main interface from the priority of interface, so, the situation of Slave interface competition becoming Master Interface can appear.
Because 120 greater than 100, so the former S2 competition success on the RouterA upgrades to Master Interface, become new M2;
Because 100 less than 120, so the former M2 competition failure on the RouterB is downgraded to the Slave interface, become new S2, so far, accomplish the handover operation of active and standby interface in the VRRP group 2.
After VRRP group 2 was switched, the Master Interface of VRRP group 1, VRRP group 3 all was positioned at RouterB, and the Master Interface of VRRP group 2, VRRP group 4 is positioned at RouterA, thereby, make the flow of two outlet RouterA and RouterB recover balanced.

In such cases, the S4 priority of current VRRP group 4 is 120, and the priority of M4 is 100, is higher than main interface from the priority of interface, so, the situation of Slave interface competition becoming Master Interface can appear.
Because 120 greater than 100, so the former S4 competition success on the RouterB upgrades to Master Interface, become new M4;
Because 100 less than 120, so the former M4 competition failure on the RouterA is downgraded to the Slave interface, become new S4, so far, accomplish the handover operation of active and standby interface in the VRRP group 4.
After VRRP group 4 was switched, the Master Interface of VRRP group 1, VRRP group 3 all was positioned at RouterA, and the Master Interface of VRRP group 2, VRRP group 4 all is positioned at RouterB, caused the flow of two outlet RouterA and RouterB to recover balanced.
As shown in Figure 8, when the M2 of RouterB occurs when unusual, the switching of active and standby interface takes place in the VRRP group 2:
Interface among the RouterB is from interface from the main interface Status Change, becomes S2;
Interface among the RouterA becomes M2 by becoming main interface from Interface status.
After VRRP group 2 was switched, according to prior art, the Master Interface of VRRP group 1, VRRP group 2, VRRP group 4 all was positioned at RouterA, has only the Master Interface of VRRP group 3 to be positioned at RouterB, causes the flow of two outlet RouterA and RouterB very unbalanced.Directly consequence is exactly that an outlet bandwidth is not enough, and another outlet bandwidth leaves unused.
Adopt technical scheme of the present invention, because S1 on RouterB detects the state of the former M2 of VRRP group 2, so when the former M2 among the RouterB takes place when unusual, then the priority parameters of S1 increases by 50 (reaching 120).
In such cases, the S1 priority of current VRRP group 1 is 120, and the priority of M1 is 100, is higher than main interface from the priority of interface, so, the situation of Slave interface competition becoming Master Interface can appear.
Because 120 greater than 100, so the former S1 competition success on the RouterB upgrades to Master Interface, become new M1;
Because 100 less than 120, so the former M1 competition failure on the RouterA is downgraded to the Slave interface, become new S1, so far, accomplish the handover operation of active and standby interface in the VRRP group 1.
After VRRP group 1 was switched, the Master Interface of VRRP group 2, VRRP group 4 all was positioned at RouterA, and the Master Interface of VRRP group 1, VRRP group 3 all is positioned at RouterB, caused the flow of two outlet RouterA and RouterB to recover balanced.
As shown in Figure 9, when the M4 of RouterA occurs when unusual, the switching of active and standby interface takes place in the VRRP group 4:
Interface among the RouterB becomes M4 by becoming main interface from Interface status;
Interface among the RouterA is from interface from the main interface Status Change, becomes S4.
After VRRP group 4 is switched; According to prior art; The Master Interface of VRRP group 2, VRRP group 3, VRRP group 4 all is positioned at RouterB, has only the Master Interface of VRRP group 1 to be positioned at RouterA, causes the flow of two outlet RouterA and RouterB very unbalanced; Directly consequence is exactly that an outlet bandwidth is not enough, and another outlet bandwidth leaves unused.

In such cases, the S3 priority of current VRRP group 3 is 120, and the priority of M3 is 100, is higher than main interface from the priority of interface, so, the situation of Slave interface competition becoming Master Interface can appear.
Because 120 greater than 100, so the former S3 competition success on the RouterA upgrades to Master Interface, become new M3;
Because 100 less than 120, so the former M3 competition failure on the RouterB is downgraded to the Slave interface, become new S3, so far, accomplish the handover operation of active and standby interface in the VRRP group 3.
After VRRP group 3 was switched, the Master Interface of VRRP group 2, VRRP group 4 all was positioned at RouterB, and the Master Interface of VRRP group 1, VRRP group 3 all is positioned at RouterA, caused the flow of two outlet RouterA and RouterB to recover balanced.
