Every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Currently, the method that user generallys use batch upgrade upgrades interchanger.But there are more for this mode
In the case that interchanger upgrades simultaneously, occur suspension phenomenon when may result in upgrading, and then leads to the interruption of corresponding business.Example
Such as when the host exchange being arranged there are redundancy and standby interchanger upgrade simultaneously, it will lead to suspension when upgrading, not only lose
The characteristics of redundancy backup, also results in the interruption of corresponding business.Therefore, by avoiding will cause service disconnection in the present embodiment
Multiple switch upgrades simultaneously to solve the above problems.Interchanger refers specifically to thin interchanger in the present embodiment, it can is interpreted as
Upgrade method in the present embodiment is applied to the upgrading of thin interchanger.Executing subject is not defined in the present embodiment, example
It such as can be network controller.Specifically referring to FIG. 1, Fig. 1 is the stream of switch upgrades method provided by the embodiment of the present invention
Cheng Tu；This method may include:
S101, judge current interchanger to be upgraded with the presence or absence of upgrading associated switch；If current interchanger to be upgraded is deposited
In upgrading associated switch, S102 is thened follow the steps；If current interchanger to be upgraded is executed there is no upgrading associated switch
Step S104.
The present embodiment is adapted to various upgrading modes.Such as separate unit switch upgrades, interchanger batch upgrade, interchanger
Automatic upgrading.Wherein, separate unit switch upgrades are the upgrading tasks that user carries out manually, are risen just for single interchanger
Grade.Interchanger batch upgrade is that user once selects more interchangers to upgrade.Interchanger upgrades usually network control automatically
After device processed first upgrades, the interchanger of administration is after discovery network controller upgrading, the escalation process of automatic batch progress.
It should be noted that upgrading associated switch in the present embodiment refer to that current switchboard direct to be upgraded may be influenced
Connect the interchanger of upgrading.Not to the current interchanger to be upgraded of judgement with the presence or absence of the side of upgrading associated switch in the present embodiment
Formula is defined.Such as can be user and preset the i.e. default upgrading relevant group of upgrading relevant group according to actual needs, pass through
Judge whether the current interchanger to be upgraded is the interchanger in default upgrading relevant group to judge that currently interchanger to be upgraded is
It is no to there is upgrading associated switch；The respective switch preset in upgrading relevant group at this time all upgrades associated switch each other.?
It can be and current interchanger to be upgraded is analyzed, judge whether it can have upgrading associated switch；I.e. according to current
The analysis result of interchanger to be upgraded upgrades associated switch to determine that it whether there is.Certainly, not to pre- in the present embodiment
If the generation type of upgrading relevant group and being defined to the content of current interchanger analysis to be upgraded, for example, user can be with
Accordingly it is arranged according to upgrading reliability and hardware computing capability.Specifically, can be by current interchanger to be upgraded
Position in the switch-layer topology for integrally needing to upgrade, there are the function of incidence relation (such as redundancy features or anti-ring mechanism)
Default upgrading relevant group is analyzed or is arranged in setting etc..Preferably, current interchanger to be upgraded is judged in the present embodiment is
It is no to may include: in the presence of upgrading associated switch
Using default upgrading relevant group, judge current interchanger to be upgraded with the presence or absence of upgrading associated switch；And/or；
Judge whether current interchanger to be upgraded has redundancy feature or anti-ring agreement.
It is understood that current interchanger to be upgraded can be only judged in the present embodiment by default upgrading relevant group
With the presence or absence of upgrading associated switch.It is also possible to only by whether redundancy feature or anti-ring agreement is arranged to judge currently wait rise
Grade interchanger is with the presence or absence of upgrading associated switch.It can certainly be that both judgment modes are set simultaneously, to interchanger
When being upgraded, judgment mode needed for selecting this switch upgrades as user.
Certainly, specific execute is not limited in the present embodiment yet and judges that current interchanger to be upgraded is handed over the presence or absence of upgrading is related
It changes planes, or the equipment whether current interchanger to be upgraded has redundancy feature or anti-ring agreement.Such as it can be directly by network
Controller realizes the process of above-mentioned judgement according to configuration information etc., naturally it is also possible to be to have current interchanger realization to be upgraded above-mentioned
The process of judgement, network controller only need to obtain corresponding judging result from current interchanger to be upgraded.As currently
Interchanger to be upgraded judges whether itself is provided with redundancy feature, if so, judging result is the presence of upgrading associated switch；So
Judging result is sent to network controller again afterwards, so that network controller executes subsequent respective upgrades plan according to the judgment result
Slightly.
For M-LAG, (Multichassis Link Aggregation Group, striding equipment link are poly- in the present embodiment
It is combined；One equipment and other two equipment are carried out striding equipment link aggregation by the mechanism for realizing striding equipment link aggregation, thus
Link reliability has been increased to device level from single-plate grade), VRRP (Virtual Router Redundancy Protocol,
Virtual Router Redundacy Protocol), stack (Stack Technology be on Ethernet switch ECP Extended Capabilities Port use more another kind of skill
Art is a kind of nonstandardized technique technology) etc. compositions redundant group, certainly, these redundant groups include but is not limited to M-LAG, VRRP, heap
It is folded, virtualization, two or three layers of redundancy scheme such as STP, OSPF；Or by STP (i.e. Spanning-Tree Protocol), RRPP (Rapid Ring
Protection Protocol, rapid ring protection protocol) etc. formation anti-ring group；It can deposit multiple switch one in the group
Upgrading is played, suspension when leading to upgrading, the characteristics of losing redundancy backup.It therefore, can be by redundant group and anti-ring in the present embodiment
Group is set as default upgrading relevant group, wherein default upgrading relevant group can be serious when can refer to interchanger in group while upgrade
A grouping for influencing customer network may include the exchange group that redundant group and anti-ring group are formed.Further, user can root
Default upgrading relevant group is updated according to the variation of whole switch-layer topology structure and the change of switch function, certainly,
It can realize that the automation of default upgrading relevant group updates according to the update condition of user setting.
The judgement side whether current interchanger to be upgraded has redundancy feature or anti-ring agreement is not limited in the present embodiment
Formula.As long as such as determining that current interchanger to be upgraded is considered as the current interchanger to be upgraded there are redundancy protocol and has redundancy function
Can, as long as determining that current interchanger to be upgraded is considered as the current interchanger to be upgraded there are anti-ring agreement and has anti-ring agreement
(particular content of anti-ring agreement is not defined in the present embodiment, such as can be STP, MSTP (i.e. Multiple Spanning Tree Protocol),
RSTP, RRPP, OSPF, RIP (Routing Information Protocol, routing information protocol), BGP (border networks association
View) etc. anti-ring agreement).It is also possible to only determining that currently interchanger to be upgraded can just be thought when successful implementation redundancy protocol
It is with redundancy feature.In order to improve the reliability of step S101 judgement.Current interchanger to be upgraded is judged in the present embodiment is
It is no to may include: with redundancy feature
Judge current interchanger to be upgraded whether configuring redundancy function；
If being configured with redundancy feature, the corresponding successful redundancy protocol of negotiation is judged whether there is；
Negotiate successful redundancy protocol if it exists, then current interchanger to be upgraded has redundancy feature.
Specifically, be not defined to the particular content of redundancy protocol in the present embodiment, certainly also it is unlimited it is settled before to
Upgrade the redundancy protocol quantity of switch configuration.For example, first judging whether current interchanger to be upgraded is configured with redundancy feature, such as
Fruit is configured with one or more redundancy features, then can check one by one whether each redundancy feature currently comes into force, i.e. judgement is arranged
Whether the corresponding redundancy protocol of each redundancy feature negotiates success, if there is successful redundancy protocol is negotiated, then currently wait rise
Grade interchanger just has redundancy feature.
It should be noted that not limiting the quantity of current interchanger to be upgraded in the present embodiment, it can refer to one
Interchanger to be upgraded may also mean that multiple interchangers to be upgraded.When it is every there are needing to judge when multiple interchangers to be upgraded
A current interchanger to be upgraded is with the presence or absence of upgrading associated switch.Certainly, the deterministic process of above-mentioned redundancy feature can be by
Network controller is realized, is also possible to be realized by current interchanger to be upgraded.
S102, the upgrading associated switch upgraded is judged whether there is；The upgrading correlation upgraded if it exists is handed over
It changes planes, thens follow the steps S103；The upgrading associated switch upgraded if it does not exist, thens follow the steps S104.
The mode and correspondence for judging whether there is the upgrading associated switch upgraded are not limited in the present embodiment
Executing subject, such as can be and SUDPU agreement (Sundray Upgrade Protocol is passed through by current interchanger to be upgraded
Data Unit, proprietary protocol are used to negotiate upgrading relevant information in more interswitch communications) upgrade related exchange with other
Machine negotiates upgrade case, it is determined whether there is the upgrading associated switch upgraded, then will be with the presence or absence of the liter upgraded
The result of grade associated switch is sent to network controller.It is of course also possible to directly be network controlled device according to respective switch
Current upgrade case is directly determined with the presence or absence of the upgrading associated switch upgraded.
Wherein, specific deterministic process can be in the default upgrading relevant group of judgement with the presence or absence of other friendships upgraded
It changes planes (other interchangers can be understood as upgrading associated switch)；If then proving there is the upgrading related exchange upgraded
Machine；If not then there is no the upgrading associated switch upgraded.Certain deterministic process is also possible to judge whether there is just
In the interchanger of upgrading；If otherwise there is no the upgrading associated switch upgraded；If then judging the exchange upgraded
Whether machine has redundancy feature or anti-ring agreement (then it is upgrading associated switch)；It proves to exist if having and upgrade
Upgrade associated switch, proves that there is no the upgrading associated switch upgraded if not having.
S103, stop executing updating operation to current interchanger to be upgraded.
The particular content for not executing updating operation to current interchanger to be upgraded to stopping in the present embodiment is defined,
As long as may be implemented to stop upgrading current interchanger to be upgraded.Such as it can be and directly exit to current to be upgraded
The upgrading process of interchanger；It is also possible to directly suspend the updating operation to current interchanger to be upgraded；It is also possible to suspending
To the prompt information of output pause upgrading on the basis of the updating operation of current interchanger to be upgraded, to remind user currently wait rise
Grade interchanger has timed out upgrading；Certainly the particular content for not limiting prompt information in the present embodiment at this time (prompts specific
Which interchanger pause upgrading, or the time etc. of which specific interchanger pause upgrading and pause upgrading) and prompt
The output form (can be character output, be also possible to voice output etc.) of information.
S104, updating operation is executed to current interchanger to be upgraded.
The detailed process of updating operation is not defined in the present embodiment, which can refer to the relevant technologies.Into
One step for other interchangers when further ensuring that current switch upgrades to be upgraded while upgrading, can be right in the present embodiment
The current switch configuration upgrading lock to be upgraded, and the current interchanger to be upgraded is held after the upgrading lock is set
The row updating operation.That is, locking upgrading lock before upgrading, after waiting for a period of time, starts to upgrade, prevent other exchanges
Machine upgrades simultaneously.
In the present embodiment when upgrading to each upgrading associated switch, or to the exchange in default upgrading relevant group
When machine upgrades, guarantee that each upgrading associated switch upgrades one by one, and only work as upper upgrading associated switch
Business recovery after upgrading could continue to upgrade next upgrading associated switch；If there is a upgrading associated switch upgrading
Failure then stops other upgrading associated switch upgradings.
Based on the above-mentioned technical proposal, switch upgrades method provided in an embodiment of the present invention, to current exchange to be upgraded
Before machine upgrading, it can first judge that the current interchanger to be upgraded whether there is the upgrading associated switch upgraded；Only exist
There is no when the upgrading associated switch upgraded, can just upgrade the current interchanger to be upgraded.Avoid associated interchanger
The case where upgrading simultaneously appearance, to avoid key business caused by upgrading the network interruption that more interchangers are likely to occur simultaneously
The case where interruption, and then ensure that the reliability of business during switch upgrades.
Based on the above embodiment, random to swap machine batch upgrade for catenet, it will lead to not expectable
Consequence, such as influence server zone and the connection of internet etc..Therefore, in upgrading multiple switch automatically in the present embodiment
Or when batch upgrade interchanger, upgrading route can be set.Successively respective switch is upgraded according to the upgrading route
Operation, prevents uncontrollable phenomenon, and upgrading is influenced to be preferably minimized.The generation of upgrading route is not limited in the present embodiment
Form can be network controller and be automatically generated according to preset rules, be also possible to upgrade route by user setting.Certainly originally
Preset rules are not defined in embodiment.Such as can using the uninterrupted of respective switch as preset rules, or
Person is using the number of users of respective switch as preset rules, then using the business characteristic of respective switch as preset rules.
Again or using the device model of respective switch as preset rules.Again or using the redundancy condition of respective switch as default
Rule.Preferably, judge that current interchanger to be upgraded can also wrap before with the presence or absence of upgrading associated switch in the present embodiment
It includes:
When receiving the instruction of interchanger batch upgrade or the automatic upgrade command of interchanger, corresponding upgrading route is generated,
And current interchanger to be upgraded is determined according to upgrading route.
In the present embodiment when swapping machine batch upgrade or interchanger upgrades automatically, device intelligence can be controlled by the network
Distribute upgrading task.It can be understood as the present embodiment provides gray scale upgrade function, it can be according to uninterrupted, number of users, business
Feature etc. intelligently generates upgrading route.
It should be noted that not limiting the generating mode of upgrading route in the present embodiment, such as collect interchanger batch
After the complete machine flow information that upgrade command or the corresponding respective switch of the automatic upgrade command of interchanger report, by flow from it is small to
Big sequence sequentially generates upgrading route.It either collects the instruction of interchanger batch upgrade or the automatic upgrade command of interchanger is corresponding
Respective switch report MAC (Media Access Control) number after, sequentially generated by the sequence of MAC number from small to large
Upgrade route.Either network controller instructs interchanger batch upgrade or the corresponding each friendship of the automatic upgrade command of interchanger
The business changed planes is divided into two layers of general type, two layers of redundancy type, three layers of general type, three layers of redundancy type；Default priority liter
Two layers of redundancy class interchanger of grade, then upgrade three layers of redundancy class interchanger, finally successively upgrade two layers of general type and three layers general
Logical type switch.Because can using the upgrade mechanism for upgrading associated switch in above-described embodiment when redundancy class switch upgrades
To guarantee network smooth upgrade, and Layer 2 switch is compared, three-tier switch is generally located at core layer.Either according to interchanger
Batch upgrade instruction or the model sequence of the corresponding respective switch of the automatic upgrade command of interchanger, low-end models liter of giving priority in arranging for
Grade finally arranges high-end models upgrading.Either when there are anti-ring group, according to the port of respective switch in anti-ring group
Block situation preferentially upgrades the interchanger more than block port number, reduces influence caused by anti-ring protocol convergence.Either work as and deposits
In redundant group, according to the active and standby situation of redundant group, accomplishes preferentially to upgrade standby interchanger, finally upgrade host exchange again, in this way
Traffic loss or network oscillation caused by frequent active-standby switch are caused when can be to avoid first upgrading host exchange, because big absolutely
In most redundancy protocols, it is usually user's unaware that standby interchanger, which disconnects,.
For example, have 3 group of switches at redundancy stacked group, user is in this 3 interchangers of batch upgrade, network-control
Device can formulate a upgrading route (paying the utmost attention to upgrade standby interchanger) according to gray scale upgrade mechanism.After generating upgrading route, rise
The interchanger of grade passes through SUDPU agreement and other two negotiations upgrade case, only when other interchangers all do not upgrade, the friendship
Changing planes can just upgrade.Upgrading lock is locked before upgrading, after waiting for a period of time, is started to upgrade, is prevented other interchangers while upgrading.
After two standby switch upgrades are complete, finally upgrade host exchange, the active-standby switch for triggering stacking is primary.Entire escalation process is only sent out
Raw 1 active-standby switch, whole process is without traffic loss.
Further, the function that network sensor automatically generates upgrading route can be only set in the present embodiment, be also possible to
The only function of the customized upgrading route of setting user.Certainly, in order to improve switch upgrades adaptation of methods in the present embodiment,
Meet the needs of various users are under various application scenarios, upgrading line can also be automatically generated in network controller in the present embodiment
On the basis of road, increase the customized default upgrading line function of user.Preferably, corresponding upgrading is being generated in the present embodiment
Can also include: before route
Judge whether there is default upgrading route；
If it exists, then using default upgrading route as upgrading route；
If it does not exist, then the step of generating corresponding upgrading route is executed.
Specifically, network controller is before automatically generating upgrading route firstly the need of judging whether there is in the present embodiment
Default upgrading route, that is, judge whether there is the default upgrading route of the customized setting of user.When there is no default upgrading routes
When, then network controller automatically generates upgrading route.When there is default upgrading route, it was demonstrated that user is customized at this time
Upgrade route, then network controller does not regenerate upgrading route, and executes friendship fully according to the default upgrading route of user setting
The escalation process changed planes.
It should be noted that not limiting default upgrading route in the present embodiment obtains form, such as it can be user's liter
Default upgrading route is sequentially formed when the network controller page specifies each switch upgrades before grade, exchange opportunity is pre- according to this
If upgrading route is successively upgraded.
User is also possible to combine uninterrupted, number of users, business characteristic, device model, redundancy condition in the present embodiment
The equal default upgrading route of settings.The present embodiment is not limited thereto.
Upgrade to can be in route in the present embodiment and be made of multiple upgrade nodes, after the completion of each upgrade node upgrading
The upgrading for executing next upgrade node, until upgrade nodes whole in the upgrading route are fully completed.In the present embodiment
The quantity of the interchanger of the respective upgrades of each upgrade node is not limited.Such as in the present embodiment no matter in the upgrading that automatically generates
It can be single switch that route, which still presets each node in upgrading route, be also possible to multiple switch.When upgrading line
When some upgrade node is multiple devices in road, all interchangers of the upgrade node in upgrading in node can rise simultaneously
Grade is just notified that the upgrading of this node of network controller is completed, executes after the completion of all interchangers in upgrade node all upgrade
The upgrading of next upgrade node.The grade of each node in each upgrade node is not limited in the present embodiment yet.Such as this reality
Applying and can specify some upgrade node in example is crucial upgrade node or common upgrade node.For crucial upgrade node, only
There is the interchanger that just will continue to one next upgrade node of upgrading after the completion of the switch upgrades of previous upgrade node.For general
Logical upgrade node, network controller can only wait its corresponding switch upgrades in the given time, if it exceeds the predetermined time,
Even if interchanger has not upgraded in common upgrade node, network controller can also arrange the interchanger in subsequent upgrade node to carry out
Upgrading.
Based on the above-mentioned technical proposal, switch upgrades method provided in an embodiment of the present invention, to current exchange to be upgraded
Before machine upgrading, it can first judge that the current interchanger to be upgraded whether there is the upgrading associated switch upgraded；Only exist
There is no when the upgrading associated switch upgraded, can just upgrade the current interchanger to be upgraded.Avoid associated interchanger
The case where upgrading simultaneously appearance, to avoid key business caused by upgrading the network interruption that more interchangers are likely to occur simultaneously
The case where interruption, and then ensure that the reliability of business during switch upgrades.And by the setting of upgrading route, prevent
Only there is uncontrollable phenomenon, upgrading is influenced to be preferably minimized, meets user individual upgrade requirement.
Based on above-mentioned any embodiment, in order to guarantee that the system business after upgrading can be executed normally in the present embodiment, this
After completing switch upgrades can also include in embodiment (such as can to the working condition of the system after switch upgrades
Be network state either business processing status) inspection, and then determine upgrading after interchanger whether can work normally.
Certainly, detection mode is not defined in the present embodiment, as long as can find business irregular operating in time, or
Person is network abnormal situation.Further, due to an automatic detecting technology (automatic equipment based on interchanger and network-like
Condition Examined effect) it can accurately and rapidly find that the plant issues such as cpu, process, the memory of interchanger and network node are lost
Packet, the inner-mesh networks problem such as exception of network traffic.It is preferred, therefore, that in the present embodiment after completing switch upgrades also
May include:
After the completion of switch upgrades, abnormal conditions are judged whether there is using automatic detecting technology；
Abnormal conditions if it exists then execute abnormal conditions processing operation.
Wherein, the judgement form that do not complete to switch upgrades in the present embodiment is defined, such as can be every
When one switch upgrades is completed, actively sending the prompt information that upgrading is completed to network controller, (certainly, switch upgrades are lost
Lose or suspend and be also possible to return corresponding prompt information), it is considered as exchanging after the prompt information for receiving each interchanger
Machine upgrading is completed.It is also possible to think that switch upgrades are completed after whole interchangers have been performed both by updating operation.
It should be noted that not being defined to the particular content of abnormal conditions processing operation in the present embodiment.Such as
It can be automatic rollback upgrading.It is also possible to export warning message.It can certainly be defeated on the basis of automatic rollback upgrading
Warning message out.Such as in the present embodiment after switch upgrades, automatic detecting technology can be called, it, can when inspection is found the problem
To select rollback upgrade package to execute automatic rollback upgrading, print warning message according to problem serious conditions.At this point, the present embodiment
The particular content of warning message is not defined.
Abnormal conditions are not defined, can be configured according to the actual situation by user in the present embodiment.Such as
It can be only key node and go wrong and just think that there are abnormal conditions；Just recognize as long as being also possible to any node and going wrong
For there are abnormal conditions.Wherein, which can be flow through a network problem, be also possible to service operation problem, naturally it is also possible to
It is other work problems.The present embodiment is not limited thereto.For example, by joining with automatic detecting technology in the present embodiment
Dynamic, the analogue flow rate after switch upgrades confirms whether the network of key node is unimpeded, and key business is whether normal operation.When
Occur in such a way that automatic rollback upgrades, carrying out network or industry in the case that network is not smooth or business irregular operating
Business restores.Wherein, the standard that the smooth standard of network and business operate normally can be defined by the user in the present embodiment.
Based on the above-mentioned technical proposal, switch upgrades method provided in an embodiment of the present invention, to current exchange to be upgraded
Before machine upgrading, it can first judge that the current interchanger to be upgraded whether there is the upgrading associated switch upgraded；Only exist
There is no when the upgrading associated switch upgraded, can just upgrade the current interchanger to be upgraded.Avoid associated interchanger
The case where upgrading simultaneously appearance, to avoid key business caused by upgrading the network interruption that more interchangers are likely to occur simultaneously
The case where interruption, and then ensure that the reliability of business during switch upgrades.And it is improved by automatic detecting technology
The reliability of system after upgrading.
Based on above-mentioned any embodiment, in order to avoid occur during switch upgrades network congestion the case where, this
In embodiment when to switch upgrades, the traffic conditions being likely to occur can be predicted, prevent network congestion
Situation.Prediction mode is not defined in the present embodiment, such as network controller can be according to certain period of time before upgrading
The port flow information of each upgrading associated switch, when prejudging certain switch upgrades, whether flow walks another interchanger
The case where will appear network congestion.Or network controller can be according to each upgrading associated switch of certain period of time before upgrading
