Execute shown or described step.
Referring to the VRRP linkage switching methods that Fig. 2 and Fig. 3, the present embodiment are proposed, it is applied to superfluous comprising multiple virtual flow-lines
The VRRP of remaining agreement VRRP groups accesses networking, specifically includes following steps：
Step S101：If there is the upstream Interface of VRRP access networkings to break down, the band of non-faulting upstream Interface is obtained
The sum of width.
It needs to illustrate, non-faulting upstream Interface is all to be connected to VRRP access networkings with failure upstream Interface
Upstream Interface, since it includes multiple VRRP groups that VRRP, which is accessed in networking, and therefore, the quantity of corresponding upstream Interface is multiple.When
When breaking down there are one upstream Interface, the band of all non-faulting upstream Interfaces in addition to this above-mentioned upstream Interface is obtained
The sum of width；When breaking down there are two upstream Interface, obtain in all non-faulting in addition to the two above-mentioned upstream Interfaces
The sum of bandwidth of line interface, and so on.
Step S102：Judge several business that the sum of bandwidth can meet simultaneously, wherein several business it is preferential
Grade is above remaining business.
Due to, it includes multiple VRRP groups that VRRP, which is accessed in networking, and therefore, the business accordingly accessed can be a variety of, also,
The priority of above-mentioned multiple business is configured in advance from high to low.When there is upstream Interface failure, by above-mentioned bandwidth it
It is compared with the occupied access bandwidth of the business of priority from high to low, judges what the sum of bandwidth can meet simultaneously
Business, by aforesaid operations can Effective selection go out several higher business of priority and the lower remaining industry of priority
Business.
In implementation process, the sequence in above-mentioned steps S102 according to service priority from high to low, judge bandwidth it
Business with that can meet simultaneously, specifically includes：
Step S1021：Judgment step judges several business that the sum of bandwidth can meet simultaneously, wherein several industry
The priority of business is above remaining business.
Wherein, the initial value of n is 1, i.e., since preceding 1 business of highest priority.If cannot, carry out step
S1022；If can, carry out step S1023.
Above-mentioned state observation table is updated by above-mentioned judgement.If there is upstream Interface failure, by failure uplink
The value of the corresponding interface field of interface is changed to fault value by normal value.
It is assumed that upstream Interface D failures occur, at this time, the state of state observation table needs to switch, i.e., by upstream Interface D
Interface field DOMN is changed to by UP, at this time, in state observation table state be UP interface there was only the sum of E and F, bandwidth
For 4G.Judge whether the sum of bandwidth can meet the preceding n business of highest priority simultaneously, need by the sum of bandwidth (i.e. 4G) with
It the access bandwidth of business A, B, C and is compared, from high-priority service, comparative sequence is as follows down always：
E+F=4G ＞ C=1G, so the bandwidth of highest priority C business can obtain effective guarantee, continuation is compared down；
E+F=4G ＞ B+C=3G, so the sum of highest priority traffic C and sub-priority business B can also be obtained effectively
It ensures, continuation is compared down；
E+F=4G<A+B+C=6G, at this time, in the case that three kinds of business exist simultaneously, bandwidth is insufficient.Reason is to compare
Compared with when add the lower business A of priority.
Step S1022：It is remaining business that judgement priority, which comes n-th and the lower business of priority,.
Correspond to above-mentioned E+F=4G<A+B+C=6G, at this time, in the case that three kinds of business exist simultaneously, bandwidth is insufficient
Operating procedure.
In this case, the business A for priority being come to the 3rd is determined as remaining business, judges lowest priority
Business needs to carry out VRRP switchings.
Step S1023：The value of n is added 1, and returns to judgment step.
Later, return to step S1021 judgment steps continue to judge whether the sum of bandwidth can meet highest priority simultaneously
Preceding n business.
Above-mentioned E+F=4G ＞ C=1G are corresponded to, so, the bandwidth of highest priority C business can obtain effective guarantee, after
It is continuous to compare down；And E+F=4G ＞ B+C=3G, so the sum of highest priority traffic C and sub-priority business B also can
Effective guarantee is obtained, the operating procedure compared down is continued.
Above-mentioned steps S103 carries out active-standby switch, specifically includes to the VRRP groups corresponding to remaining business：
According to the value of mode field, continue the above example and illustrate, the value of mode field is 1, determines remaining business
VRRP groups are the VRRP groups corresponding to business A.
Later, to corresponding to remaining business VRRP groups carry out active-standby switch, i.e., by the VRRP groups corresponding to business A into
Row active-standby switch.
Continue the above example to illustrate, similarly, after E exports failure again, then executes step S1021：According to above-mentioned side
The description of method is compared,
F=2G ＞ C=1G, so the bandwidth of highest priority C business can obtain effective guarantee, continuation is compared down；
F=2G<B+C=3G, at this time, the sum of highest priority traffic C and sub-priority business B cannot be protected effectively
Barrier, bandwidth are insufficient.Reason is to add sub-priority business B in comparison.
Step S1022 is executed again：In this case, business A and business B is remaining business, by business A and business
The interface field of B is changed to DOWN.It is corresponding that the mode field initial value 100 of business B in state observation table is updated to business B
The configuration 2 of VRRP groups.
Informing VRRP group switches over after the state of state observation table changes, because Status is 2, business A is
Switching, and keep present situation, business B to meet switching condition triggering VRRP switchings without triggering switchback condition, business C, which is not met, to be cut
Changing condition, then corresponding VRRP groups do not switch.
Similarly, after F exports failure again, then step S1021 is executed：It is compared according to the description of the above method,
0G<C=1G, so the bandwidth of highest priority C business cannot obtain effective guarantee, bandwidth is insufficient.
Step S1022 is executed again：In this case, business A, business B and business C are remaining business, by business
A, the interface field of business B and business C are changed to DOWN.The mode field initial value 100 of business B in state observation table is updated
For the configuration 3 of the corresponding VRRP groups of business C.
Step S103：To the VRRP groups corresponding to remaining business, active-standby switch is carried out.
It is after judging the business that the sum of above-mentioned bandwidth can meet simultaneously by step S102, i.e., while also corresponding
The remaining business of the sum of above-mentioned bandwidth, i.e., remaining business are judged.In this case, it is right to choose remaining business institute
The VRRP groups answered carry out active-standby switch, to targetedly realize the active-standby switch of specific VRRP groups, make above-mentioned remaining
It is gone in service switching to standby equipment, and then ensures that business carries out normal operation in standby equipment.
In order to be monitored in real time to the state of upstream Interface, which further includes：Pre-set shape
State observes table, and for the ease of carrying out status monitoring to each business, a virtual observation group is established for each business in equipment.
For example, it is assumed that VRRP access networking in, downlink access there are three kinds of business A, B, C, corresponding bandwidth be all respectively 3G,
2G, 1G, the sequence of priority from high to low are C, B, A.There is outlet D, E, F of equal value in upstream Interface, bandwidth is all 2G respectively,
Upstream Interface D, E, F are added in the virtual observation group, meanwhile, downlink business A, B, C are according to respective service priority point
It is not added in the virtual observation group.
Also, above-mentioned state observation table includes mode field and multiple interface fields, and value and the uplink of interface field connect
The state of mouth is related.Continue the above example to illustrate, due to, above-mentioned D, E, F are upstream Interface, therefore, the interface word of D, E, F
The value of section is UP, and in implementation process, the number of this interface field can be carried out according to the quantity of the upstream Interface of addition
Extension；Mode field is specially the interface bandwidth according to the bandwidth and VRRP groups of each upstream Interface the linkage virtual observation group
With determine.
The value of above-mentioned mode field is related to the value of each interface field, also, the value of mode field characterizes remaining industry
The corresponding VRRP groups of business.Specifically, following relationship is established for the value of above-mentioned mode field and the value of each interface field, it is above-mentioned
The configuration of the corresponding VRRP groups of downlink business A, B, C is as follows：
VRRP A track watch1 status 1
VRRP B track watch1 status 2
VRRP C track watch1 status 3
The value of mode field characterizes the VRRP groups corresponding to remaining business, is shown from the point of view of above-mentioned configuration when uplink connects
Only there are one when upstream Interface failure, need business A carrying out active-standby switch in mouth D, E, F；When only there are one upstream Interface events
When barrier, need business A carrying out active-standby switch；When there are two upstream Interface failure, need business A and B carrying out active and standby cut
It changes；It needs business A carrying out active-standby switch；When there are three upstream Interface failure, need business A, B and C carrying out active and standby cut
It changes, to ensure that the sum of bandwidth of upstream Interface on main equipment is more than the sum of the bandwidth of business to be treated, for main equipment
Upper unappeasable business transfers to standby equipment to be handled.
In implementation process, first the mode field to each upstream Interface and multiple interface fields assign initial value, to show to work as
The state of preceding each upstream Interface.It is under original state, the state observation table setting of upstream Interface D, E, F is as follows：
Table 1
| Index | Watch | D type | E type | F type | Status |
| 1 | watch1 | UP | UP | UP | 100 |
It is the value setting acquiescence of mode field before VRRP groups carry out active-standby switch here, needing to illustrate
Value, here, default value are more than the numerical value of the corresponding mode field of highest priority traffic of business, as shown in table 1, default value
Size can flexible customization as needed, in the present embodiment, as shown in Table 1, mode field, that is, status values are 100, greatly
In the status values 1,2,3 of the corresponding VRRP groups of above-mentioned business A, B, C, so, three kinds of business A, B, C will not trigger VRRP groups
Carry out active-standby switch.
The case where corresponding to business A in above-mentioned steps 1022 being remaining business.By the shape of business A in state observation table
State field initialization values 100 are updated to the configuration 1 of the corresponding VRRP groups of business A.
At this time state observation table is as follows：
Table 2
| Index | Watch | D type | E type | F type | Status |
| 1 | watch1 | DOWN | UP | UP | 1 |
It is the value setting acquiescence of mode field before VRRP groups carry out active-standby switch here, needing to illustrate
Value obtains the value with the relevant mode field of value of current each interface field in the case where business A is remaining business,
As shown in upper table 2, the value of the mode field of the corresponding VRRP groups of above-mentioned business A is 1, so, the VRRP group meetings corresponding to business A
Carry out active-standby switch.
Above-mentioned steps S103 carries out active-standby switch, specifically includes to the VRRP groups corresponding to remaining business：
According to the value of mode field, continue the above example and illustrate, the value of mode field is 1, determines remaining business
VRRP groups are the VRRP groups corresponding to business A.
Later, to corresponding to remaining business VRRP groups carry out active-standby switch, i.e., by the VRRP groups corresponding to business A into
Row active-standby switch.
It is remaining business corresponding to business A in above-mentioned steps 1022 and business B, by the interface word of business A and business B
Duan Jun is changed to DOWN.The mode field initial value 100 of business B in state observation table is updated to the corresponding VRRP groups of business B
Configuration 2.
At this time state observation table is as follows：
