In the invention, the main equipment is a same route equipment, and the stand-by equipment is one of multi backup group in same route equipment; the main equipment only having one backup group sends a message for indicating the main equipment is in normal running state to the standby equipment in said backup group; if the receiving of message by the standby equipment in the standby group is over time, all standby groups simultaneously make man/standby switch. By the invention, the amounts of the messages between route devices will be not increased after the amount of backup group are increased.
Description
Technical field
The present invention relates to active and standby handoff technique, be particularly related to a kind of main/standby switching method of routing device, the virtual routing device redundancy protocol of a kind of expansion (Virtual Router Redundancy Protocol, VRRP) method of backup group number and a kind of route backup system.
Background technology
In the prior art, usually adopt the VRRP technology to make a plurality of routing devices of network side can support the backup group of corresponding different sub-network, be in a plurality of routing devices one as the backup group master with (Master) equipment, other routing device as backup group standby (Backup) equipment, at least one the corresponding identical virtual ip address of all routing devices in backup group.
At any time, support to have only the host apparatus of a routing device as this backup group in a plurality of routing devices of a backup group, other at least one routing devices are as stand-by equipment; If fault has taken place in the routing device as this backup group host apparatus, then this routing device will self switch to the stand-by equipment of this backup group, and in other at least one routing devices, the routing device that routing device priority in this backup group is the highest will self switch to the host apparatus of this backup group, thereby realizes active and standby switching.
In the practical application, routing device can be for as equipment such as the layer-3 switch of static configuration default gateway or routers.
Specifically, for a backup group, as the routing device operate as normal of its host apparatus the time, at each default announcement cycle (Advertisement_Interval, Adver Int), sends the message of an expression host apparatus operate as normal, for example based on announcement (Advertisement) message of VRRP to other routing devices as this backup group stand-by equipment, to notify other routing devices, current routing device as host apparatus is in normal operating conditions.When as the routing device of stand-by equipment in predetermined period, for example announce in the cycle, do not receive the message of expression host apparatus operate as normal, promptly the stand-by equipment receive time-out then carries out active and standby switching.
Fig. 1 is the structural representation of Advertisement message.As shown in Figure 1, generally include following field in the existing Advertisement message: protocol version (Version), for example the Version that the 2nd edition VRRP (VRRPv2) is corresponding is 2; VRRP type of message (Type), for example the Type based on the Advertisement message correspondence of VRRP is 1; Virtual router number (Virtual RtrID, VRID), i.e. backup group numbering, span can be 1～255; Priority (Priority), span can be 0～255; The virtual ip address number of backup group (Count IP Addrs); Auth type (Auth Type), expression authenticates the mechanism that is adopted to the message that receives; AdverInt can be unit with the second, and default value can be 1 second; 16 verification and (Checksum) is used for detecting the data corruption situation of VRRP message; IP address (IP Address) 1～IP Addressn, the virtual ip address list item of expression backup group, n equals Count IP Addrs; Authenticator (Authentication Data) 1 and Authentication Data 2.
In routing device and routing device, also need to be provided with the backup group parameter such as routing device priority, message authentication information, timer of this backup group as this backup group stand-by equipment as a backup group host apparatus; If support a plurality of backup groups, then at the same time in the routing device and routing device as a plurality of backup group host apparatus, the backup group parameter of a plurality of backup groups need be set as a plurality of backup group stand-by equipments.
In the practical application,, and the virtual ip address of corresponding backup group is configured on the corresponding terminal next hop address as this terminal with the backup group of correspondence virtual routing device as the terminal in its corresponding subnet.
For this terminal, because corresponding at least one virtual ip address of backup group, therefore, when the routing device as the host apparatus of this backup group breaks down and carries out active and standby switching, the next hop address of this terminal does not change, thereby can guarantee the connection of this terminal and corresponding virtual routing device, and then can keep network can not be subjected to switching the influence of the Single Point of Faliure that produces owing to the routing device of different addresses.
Identical a plurality of routing devices are corresponding a plurality of subnets simultaneously, the corresponding subnet of backup group, and therefore, identical a plurality of routing devices can be supported a plurality of backup groups simultaneously.
In this case, support simultaneously in a plurality of routing devices of a plurality of backup groups,, can send the message of an expression host apparatus operate as normal to each routing device as this backup group stand-by equipment as the routing device of the host apparatus of each backup group.That is to say, represent between two routing devices that the message amount of host apparatus operate as normal can equivalent increase along with the increase of backup group quantity.
Like this, when the quantity of the backup group of identical a plurality of routing devices conduct simultaneously is many, the message of host apparatus operate as normal will appear representing in a large number between above-mentioned a plurality of routing devices.
Message with expression host apparatus operate as normal is that Advertisement message, two routing devices need support simultaneously that 1000 backup groups are example, if a host apparatus in two routing devices as 1000 backup groups, another is as the stand-by equipment of 1000 backup groups, then in an announcement cycle, routing device as host apparatus can be all backup groups, sends 1000 Advertisement messages to the routing device as stand-by equipment.And the quantity of backup group is many more, and the Advertisement message between above-mentioned routing device will be many more, when the Advertisement message reaches some, may produce the Advertisement message and flood, thereby cause network traffic congestion, influence the forwarding of other service traffics.
And, the Advertisement message need be handled by the CPU in the routing device that receives this message, but because the CPU disposal ability of routing device is limited, when a large amount of Advertisement messages pour in simultaneously, this routing device can't in time be handled because the Advertisement message is too many possibly, perhaps cause its hardware queue to overflow and abandon the Advertisement message, thereby cause the stand-by equipment receive time-out and switch to host apparatus, cause the network concussion, the flow that influences in the network is transmitted.
In order to address the above problem, the quantity with the backup group of identical a plurality of routing device supports is limited to below 300 usually, but has so just limited the VRRP The Application of Technology, can't satisfy the actual needs of more backup groups; More if desired backup group is merely able to increase the quantity of routing device, for example, when 600 backup groups of needs, provide 4 routing devices, wherein, per 2 routing devices are as 300 backup groups, but can make hardware cost long along with the increase of backup group forms multiplication like this.

In the practical application, can be provided with by manual, in as the routing device of the host apparatus of at least two backup groups and in the routing device as the stand-by equipment of at least two backup groups, any one backup group at least two backup groups is set to senior backup group, for example, for any one backup group is provided with one and the corresponding special identifier of its numbering, and the senior backup group that is provided with in the routing device of the stand-by equipment of the routing device of the host apparatus of at least two backup groups of conduct and at least two backup groups of conduct is identical; Perhaps, adopt Automatic Styles, promptly as the routing device of the host apparatus of at least two backup groups and routing device as the stand-by equipment of at least two backup groups, negotiate any one backup group at least two backup groups as senior backup group, for example, routing device as the host apparatus of at least two backup groups elects a backup group as senior backup group from least two backup groups at random, and notice is as the routing device of the stand-by equipment of at least two backup groups.
That is to say,, will self switch to the stand-by equipment of above-mentioned at least two backup groups, simultaneously, will self switch to the host apparatus of above-mentioned at least two backup groups for the stand-by equipment of backup group as above-mentioned two as the host apparatus of above-mentioned at least two backup groups.
In this step, if be a plurality of as the routing device of alternate device, the highest one of routing device priority will himself switch to the host apparatus of above-mentioned at least two backup groups in the then senior backup group.
So far, this flow process finishes.
By above-mentioned flow process as seen, the main/standby switching method of routing device in the present embodiment, for routing device, do not need all to send for all backup groups the message of the normal operation of expression host apparatus as the routing device of all backup group host apparatus, and only need this routing device is the message that senior backup group sends the normal operation of expression host apparatus, make the message amount between routing device can equivalent not increase along with the increase of backup group quantity, thereby can under the prerequisite that does not increase routing device, improve the backup group quantity that a plurality of routing device is supported.Owing under the situation that increases backup group quantity, do not need to increase routing device, thereby make the realization such scheme not need additionally to increase cost.
For backup group, above-mentioned at least two backup groups are set to bundle status, in each announcement cycle, the host apparatus of any one backup group of the senior backup group of conduct that only elects, send the message of the normal operation of expression host apparatus to its stand-by equipment, and under the situation of the stand-by equipment receive time-out of this backup group, all backup groups that are set to bundle status all carry out active and standby switching, the feasible activestandby state that is set at least two backup groups of bundle status, all follow senior backup group transition, thereby can enlarge the backup group quantity that is set to bundle status arbitrarily.
In the practical application, the senior backup group because active and standby switching places one's entire reliance upon, therefore, elect the situation of senior backup group for manual set-up mode, in as the routing device of the host apparatus of at least two backup groups and in the routing device as the stand-by equipment of at least two backup groups, routing device priority in the senior backup group only need be set, need not to be provided with the routing device priority in other backup groups except that senior backup group; Only the pairing message authentication information of senior backup group need be set, the authentication mechanism of senior backup group can be consistent with current mechanism, and need not to be provided with the message authentication information of other backup group correspondences except that senior backup group; Whether the timer of senior backup group only need be set, be used for determining the announcement cycle, the timer of other backup groups except that senior backup group disposes and does not come into force, overtime will being as the criterion with the timer of senior backup group.
Like this, need backup group parameter with all backup groups all be arranged on than prior art as in the routing device of the host apparatus of at least two backup groups and in the routing device as the stand-by equipment of at least two backup groups, the present invention only need be provided with the backup group parameter of senior backup group, has reduced the complexity that parameter is provided with in the routing device.
And elect the situation of senior backup group for automatic negotiation mode, because which at least two backup groups can't determine the senior backup group of electing in advance is, therefore, preferably, backup group parameters such as the routing device priority in all backup groups, message authentication information, timer all are arranged in the routing device.
No matter be that manual set-up mode is elected senior backup group, still automatic negotiation mode is elected senior backup group, preferably, the numbering of the virtual ip address of each backup group and each backup group etc. all is arranged on as in the routing device of the host apparatus of two backup groups and the routing device as the stand-by equipment of two backup groups at least at least.
In the embodiment of the invention, the message of the normal operation of expression host apparatus can be Advertisement message or other self-defined messages.Correspondingly, for stand-by equipment,, when not receiving Advertisement message or other self-defined messages for a long time, all can regard receive time-out as according to the type of message of making an appointment.
If the message of the normal operation of expression host apparatus is the Advertisement message, then the VRID in the Advertisement message is the numbering of the senior backup group that elects; If the message of the normal operation of expression host apparatus is self-defined message, then preferably, also should comprise the numbering of the senior backup group that elects in this message.
Below, the route equipment backup system in the embodiment of the invention is elaborated.
Route equipment backup system in the present embodiment comprises: at least two backup groups, wherein, any one at least two backup groups is the senior backup group that elects in advance.
The host apparatus of at least two backup groups is same routing device, and the stand-by equipment of at least two backup groups is at least one identical routing device.
The host apparatus of the senior backup group at least two backup groups, the stand-by equipment in this backup group send the message of the normal operation of expression host apparatus.
Under the situation of the stand-by equipment receive time-out of senior backup group, promptly do not receive the message of the normal operation of expression host apparatus in the predetermined period, at least two backup groups carry out active and standby switching simultaneously.
By said system as seen, present embodiment does not need the host apparatus of all backup groups all to send the message of the normal operation of expression host apparatus, message amount between routing device can equivalent not increase along with the increase of backup group quantity, thereby can under the prerequisite that does not increase routing device, improve the backup group quantity that a plurality of routing device is supported.Owing under the situation that increases backup group quantity, do not need to increase routing device, thereby make the realization said system not need additionally to increase cost.
In the said system, can be in as the routing device of the host apparatus of at least two backup groups and routing device as the stand-by equipment of described at least two backup groups, any one backup group at least two backup groups is set to senior backup group, and identical as the senior backup group that is provided with in the routing device of the host apparatus of at least two backup groups and the routing device as the stand-by equipment of described at least two backup groups, promptly adopt manual set-up mode to elect senior backup group.
Elect the situation of senior backup group for adopting manual set-up mode, in as the routing device of the host apparatus of at least two backup groups and routing device as the stand-by equipment of at least two backup groups, the backup group parameters such as priority, message authentication information and timer of routing device in the pairing senior backup group of senior backup group only need be set, to simplify the parameter setting of routing device.
In the said system, can also be by routing device as the host apparatus of at least two backup groups, consult with routing device as the stand-by equipment of at least two backup groups, determine that same backup group is as senior backup group at least two backup groups, promptly negotiation mode is elected senior backup group automatically.
More than be to the main/standby switching method of routing device in the embodiment of the invention and the explanation of route equipment backup system, below, in conjunction with instantiation, the technical scheme in the embodiment of the invention is further specified.
Fig. 3 is the structural representation of route backup system in the embodiment of the invention.As shown in Figure 3, comprise two routing devices in this system, be routing device 1 and routing device 2, routing device 1 and routing device 2 are supported N backup group simultaneously, be backup group 1～backup group N, the respectively corresponding external switch 1～switch N that links to each other with routing device 2 with routing device 1 simultaneously of backup group 1～backup group N, subnet of each switch correspondence.
Example 1:
Message with the normal operation of expression host apparatus is that the Advertisement message is an example, suppose that routing device 1 and routing device 2 are simultaneously as 1000 backup groups, be N=1000, and the stand-by equipment that the host apparatus of 1000 backup groups is 1,1000 backup groups of routing device is routing device 2.Like this, elect a senior backup group, just only need routing device 1 in each announcement cycle, to send the Advertisement message of the normal operation of 1 expression host apparatus to routing device 2.And, even if increase again any amount with the backup group of routing device 1 as host apparatus, in each announcement cycle, the Advertisement message amount between routing device 1 and the routing device 2 still is 1.
The flow of 1000 switches is all transmitted by routing device 1.If as routing device 2 receive time-outs of the stand-by equipment of senior backup group, then 1000 backup groups carry out active and standby switching simultaneously, the flow of 1000 switches is all transferred to routing device 2.
As seen, in these cases, the backup group quantity that routing device 1 and routing device 2 are supported can unrestrictedly increase, and can not increase Advertisement message amount between routing device 1 and the routing device 2, more can not increase burden as the routing device 2 of the stand-by equipment of 1000 backup groups.
Example 2:
Still the message with the normal operation of expression host apparatus is that the Advertisement message is an example, suppose that routing device 1 and routing device 2 are simultaneously as 1000 backup groups, be N=1000, wherein the host apparatus of 500 backup groups is routing device 1, stand-by equipment is routing device 2, the host apparatus of other 500 backup groups is routing device 2, stand-by equipment is routing device 1, is about to per 500 backup groups and bundlees respectively.Like this, wherein elect a senior backup group 1 in 500 backup groups, and in other 500 backup groups, elect a senior backup group 2, only need routing device 1 to send the Advertisement message of the normal operation of 1 expression host apparatus to routing device 2 in each announcement cycle, routing device 2 sends the Advertisement message of the normal operation of 1 expression host apparatus to routing device 1 in each announcement cycle.And, even if increase again any amount with routing device 1 as the backup group of host apparatus and/or increase any amount with the backup group of routing device 2 as host apparatus, in each announcement cycle, the Advertisement message amount between routing device 1 and the routing device 2 still is 2.
In 1000 switches, the flow of 500 switches is transmitted by routing device 1, and the flow of other 500 switches is transmitted by routing device 2.If as routing device 2 receive time-outs of the stand-by equipment of senior backup group 1,500 backup groups of then senior backup group 1 correspondence carry out active and standby switching simultaneously, the flow of 500 switches of former cause routing device 1 converting flow is all transferred to routing device 2; If routing device 1 receive time-out as the stand-by equipment of senior backup group 2, other 500 backup groups of then senior backup group 2 correspondences carry out active and standby switching simultaneously, and the flow of 500 switches of former cause routing device 2 converting flows is all transferred to routing device 1.
As seen, in these cases, the backup group quantity that routing device 1 and routing device 2 are supported also can unrestrictedly increase, and can not increase Advertisement message amount between routing device 1 and the routing device 2, more can not increase burden as the routing device 1 and the routing device 2 of stand-by equipment.
By above-mentioned two examples as seen, elect one from a plurality of backup groups, then the backup group quantity that can support of routing device 1 and routing device 2 can enlarge.And, if according to existing scheme, routing device 1 and routing device 2 can be supported 100 backup groups, and in each announcement cycle, Advertisement message amount between routing device 1 and the routing device 2 is 100, then adopt the scheme in the embodiment of the invention after, the backup group quantity that routing device 1 and routing device 2 can be supported is 100 * N, and in each announcement cycle, the Advertisement message amount between routing device 1 and the routing device 2 is minimum can be 1.
That is to say that the backup group quantity that the present invention can make identical a plurality of routing device support increases exponentially, and can not increase the message amount between routing device, more can not increase burden as the routing device of the stand-by equipment of backup group.Owing under the situation that increases backup group quantity, do not need to increase routing device, thereby make the technical scheme in the realization embodiment of the invention not need additionally to increase cost.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of being done, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
