As shown in Fig. 2, for the entire flow schematic diagram of the 3PC agreement provided in one embodiment.Referring to Fig. 2,3PC agreement The submission process of affairs is divided into CanCommit, PreCommit, DoCommit three phases to handle.Interactive process The middle distributed node needed as coordinator carries out network interaction with the distributed node as participant, completes affairs jointly Submission.In the CanCommit stage, the distributed node as coordinator is issued to all distributed nodes as participant CanCommit request comprising affairs content, asks whether that affairs can be submitted, and wait all distributions as participant The answer of node；Distributed node as participant is after receiving CanCommit request, if it is considered to affairs behaviour can be executed Make, then feed back YES and enter the PreCommit stage, otherwise feeds back NO.Distribution in the PreCommit stage, as coordinator Node issues PreCommit request, all distributed nodes as participant to all distributed nodes as participant Feeding back ACK response can then enter the DoCommit stage after receiving PreCommit request, if any one distribution as participant Formula node feeding back NO response, or as coordinator distributed node wait time-out be not received by it is all as participant's When distributed node is fed back, then the submission process of affairs can be interrupted.Distributed node in the DoCommit stage, as coordinator DoCommit request is issued to all distributed nodes as participant, all distributed nodes as participant are receiving Feeding back ACK response can then complete the submission of affairs after PreCommit request, if any one is anti-as the distributed node of participant NO response is presented, or the distributed node as coordinator waits time-out to be not received by all distribution sections as participant When point feedback, then the submission process of affairs can be interrupted.
As shown in figure 3, in one embodiment, providing a kind of anomalous structure method of distributed protocol.The present embodiment Mainly illustrated in this way applied to any one distributed node included by distributed type assemblies 120 in above-mentioned Fig. 1.
Referring to Fig. 3, the anomalous structure method of the distributed protocol specifically comprises the following steps:
S302 determines the corresponding link of feature message when monitoring feature message.
Distributed type assemblies can be restrained sometime there is abnormal scene are as follows: be occurred before some network interaction abnormal It is exactly before the transmission of some network message, at some before some network interaction with the appearance exception after some network interaction It is exactly after the transmission of some network message, therefore, when monitoring some feature message, after execution S302 after network interaction The step of, the abnormal scene that distributed type assemblies often occur can be constructed.
Wherein, feature message is the network message and exception institute needle to be constructed for the network message feature for meeting setting Pair network message.Link is the corresponding data transmission channel of feature message.In order to reliably for based on distributed association Some network message structural anomaly scene of view, distributed node just need interacting based on distributed protocol to transmission Network message is monitored, and when monitoring feature message, determines link corresponding to feature message.
In one embodiment, network message feature can be preset on distributed node by drilling terminal, be distributed Formula node can be monitored network message according to the network message feature of setting.Each distributed node is entire distributed Function in cluster may be different, different network message features can be arranged for the distributed node of different function, with structure Make the exception for heterogeneous networks interaction.Can also to multiple network message features are arranged on current distributed node, in this way, It, can be respectively to these network message structural anomalies when distributed node monitoring monitors corresponding network message respectively.
For example, for 3PC agreement, can for " CanCommit request message ", " CanCommit response message ", " PreCommit request message ", " PreCommit response message ", " DoCommit request message ", " DoCommit response report Corresponding network message feature is respectively set in text ", " Abort message " and corresponding " Ack message " etc..That is, different The network message of type has corresponded to different network message features, in this way, in monitoring network message, so that it may according to network report Literary feature judges type of message, so that it is determined that monitoring feature message.
In one embodiment, when monitoring feature message, the step of determining feature message corresponding link, is specifically wrapped It includes: the network message that monitoring is transmitted based on distributed protocol；The determining and preset network message characteristic matching from network message Feature message；According in feature message source address and destination address determine corresponding link.
Wherein, network message mentioned by method provided herein refers to interacting based on distributed protocol Network message, the message that the intercommunication of distributed node generates when without including executing method provided herein.Net Network message characteristic may thereby determine that the network for determining distributed protocol and type of message belonging to the network message of monitoring Whether message is characterized message.
Specifically, distributed node can be monitored to based on the network message that distributed protocol transmits, and according to pre- If network message feature feature message is determined from the network message of monitoring, according to the message format of feature message, extract report The content of text, obtains the source address and destination address in feature message, uses so as to be determined according to source address and destination address In the link of transmission this feature message.The link is another distribution section in current distributed node and distributed type assemblies The link that point interacts.
As shown in figure 4, for the schematic diagram of the network message based on 3PC agreement in one embodiment.Referring to Fig. 4, number 1 is arrived 12 network message is all based on the message that 3PC agreement interacts.As the distributed node of coordinator, as participant A Distributed node and distributed node as participant B these network messages can be monitored, thus at this Structural anomaly before and after the transmission of a little network messages also can reliably simulation 3PC agreement go out in each stage of network interaction Now abnormal scene.
In some embodiments, the network message feature of setting includes: IP address, port, message length, message length model It encloses.For non-encrypted network message, the network message feature of setting can also include message content；For the network report of encryption Text, the network message feature of setting can also include the temporal signatures such as frequency, sequencing that message is sent.
Wherein, IP address and port, which are used to determine, runs on distributed node and the node that network message is originated from Distributed Application process, or determine the distribution run on the network message distributed node and the node that will be sent to Application process, so that it is determined that distributed protocol corresponding to the network message.Specifically, distributed node can extract monitoring The IP address of network message and port match the IP address of extraction and port with preset IP address and port, can be with Judge whether the network message is the network message based on some distributed protocol.
Byte number shared by general different type message is different, has different message lengths, therefore message length, message Length range can be used for further judging the type of message of the network message.Distributed node can be further calculated and be monitored Network message message length, it is matched with preset message length, successful match then illustrates that the network message is Feature message.
Be not enough to distinguish the network message of type of message for message length, message length range, network message not by In the case where encryption, distributed node can also extract some or all of network message message content, will be in the message of extraction Appearance is matched with preset message content, and successful match then illustrates that the network message is characterized message.Added in network message In the case where close, frequency, the sequencing etc. that distributed node can be sent with statistics network message, by the frequency of statistics, successively Sequence is matched to preset corresponding message characteristic, and successful match then illustrates that the network message is feature message.
S304, according to preset exception-triggered opportunity, the network message that persistent cache passes through link transmission.
Since are sometime there is abnormal scene and can converge to occur before some network interaction in distributed type assemblies Exception and the appearance exception after some network interaction, therefore, in order to reliably be constructed according to preset exception-triggered opportunity Abnormal scene needs distributed node persistent cache it is necessary to prevent distributed node from normally interacting before Pending The Entry Into Force in exception The network message transmitted between distributed node corresponding with determining link.The network message of transmission is another including being sent to The network message that the network message of distributed node and another distributed node to be received are sent.It is, by generation to The network message elder generation persistent cache of transmission, wouldn't be sent to another distributed node；Network message to be received is first buffered in It is local, the Distributed Application process of local runtime wouldn't be transferred to.
Exception-triggered opportunity is cacoplastic opportunity when monitoring feature message, can be to by determining in step S302 The message transmitted between link is cached to guarantee to construct when monitoring feature message according to preset exception-triggered opportunity It is abnormal.Preset exception-triggered opportunity includes being triggered before transmitting message after triggering and transmitting message.The network message of caching is logical The network message of determining link transmission is crossed, that is, does not include that distributed node executes method phase provided herein The message of mutual communication transmission, can guarantee the smooth execution of method provided herein.
In one embodiment, exception-triggered opportunity can be preset on distributed node by drilling terminal, be distributed Formula node can be cached according to the exception-triggered opportunity of setting to by the network message of link transmission.Different distributions formula Preset exception-triggered opportunity can be configured according to rehearsal purpose of the reality when drilling extremely on node.For same class The feature message of type different distributed nodes can be set different exception-triggered opportunitys, also can be set identical different Normal trigger timing.For same distributed node, multiple and different abnormal touchings can be set for same type of feature message Hair opportunity triggers after being also possible to transmitting message it is, triggering before can be transmitting message.
For example, the network message feature of setting is feature corresponding with A message, setting for same distributed node Exception-triggered opportunity is to trigger before receiving feature message, then can start to cache message before receiving A message, will receive extremely It is triggered before A message；For another example, the network message feature of setting is feature corresponding with B message, the exception-triggered opportunity of setting For receive feature message after trigger, then can start after receiving B message caching message, will be extremely after receiving B message Triggering.Here A message and B message can be same type of network message, be also possible to different types of network message.
In one embodiment, according to preset exception-triggered opportunity, the network message that persistent cache passes through link transmission The step of specifically include: when preset exception-triggered opportunity be transmitting message before trigger when, then persistent cache includes feature message Inside, network message by link transmission；When being triggered after preset exception-triggered opportunity is transmitting message, then persistently delay Deposit network message not including feature message, by link transmission.
Specifically, when triggering before preset exception-triggered opportunity is transmitting message, then the spy arrived in transmission of monitoring is needed Levy structural anomaly before message, therefore, it is necessary to persistent cache including the feature message monitored, passed by above-mentioned link Defeated network message, that is, first by feature packet buffer, could construct to meet in step S306 and " be touched before transmitting message The exception of hair ".If this feature message is the network message pending seen off generated, it can be realized and sent out in this feature message Structural anomaly before seeing off can be realized the distribution in local runtime if this feature message is network message to be received Formula application process receives structural anomaly before this feature message.
When being triggered after preset exception-triggered opportunity is transmitting message, then the feature message that needs to arrive in transmission of monitoring it Structural anomaly afterwards, therefore, it is necessary to persistent cache not including the feature message monitored, net by above-mentioned link transmission Network message, that is, after transmission feature message just starts to cache message, could construct to meet in step S306 and " is passing Triggered after defeated message " exception.If this feature message is the network message pending seen off generated, can be realized in the spy Structural anomaly can be realized if this feature message is network message to be received in local after sign message is transmitted The Distributed Application process of operation receives structural anomaly after this feature message.
In the above-described embodiments, it can be avoided and constructing by the feature message of above-mentioned link transmission by persistent cache Abnormal Pending The Entry Into Force in the case where normal communication between distributed node, enable the exception of construction accurately in certain exception It comes into force under scene.
Biography when in some embodiments, in order to directly be based on distributed protocol progress network interaction between distributed node Defeated network message is distinguished with the message generated when method provided herein is in communication with each other is executed, and improves buffer network report Network interface card that Distributed Application process uses and provided herein can be arranged in the efficiency of text on each distributed node Network interface card used in the anomalous structure device of distributed protocol.Also, after distinguishing message, in monitoring feature message, it is only necessary to The network message for the network interface card transmission that Distributed Application process uses is monitored, can be improved and monitor spy from network message The efficiency for levying message, to improve the efficiency of structural anomaly scene.
As shown in figure 5, for the block schematic illustration of distributed node in one embodiment.Referring to Fig. 5, in distributed node Operation has the Distributed Application process 502 realized based on distributed protocol on 500, further includes based on method provided herein The anomalous structure device 504 of the distributed protocol of realization, further includes network protocol stack 510, and network protocol stack 510 includes realizing to divide The protocol stack code of the anomalous structure device 504 of the protocol stack code and realization distributed protocol of cloth application process 502.Point Cloth node 500 further includes the business network interface card 506 for being used for transmission the network message of Distributed Application process generation, further includes distribution The rehearsal network interface card 508 that the anomalous structure device 504 of formula agreement uses, rehearsal network interface card 508 are used for transmission each distributed node and are holding The message that row method provided herein generates when needing to be in communication with each other.For example, the first distributed node passes through rehearsal network interface card Notify the cacoplastic message of the second distributed node.In some embodiments, it is also possible to rehearsal network interface card 508 is not needed, it is only right Business network interface card 506 is cached by the network message of determining link transmission.
S306, according to preset rehearsal scene, construction meets the exception on exception-triggered opportunity.
Wherein, rehearsal scene is the abnormal scene of simulation.Drilling scene may include network partition exception scene, for surveying The network partition fault-tolerance of distributed protocol is tried, the exception that network partition exception scene can construct includes: network delay, network Shake, network interruption, message loss, message delay, message shake, message error, network interruption and network interface card damage etc..Grinder Scape can also include hard disk exception scene, be used for testing hard disk fault tolerance, the exception that can be constructed under hard disk exception scene It include: relatively slow hard disk corruptions, hard disk Out of Memory, hard disk reading speed, fixed disk file damage, fixed disk file size more than system Limitation and fixed disk file loss etc..Drilling scene can also include distributed node exception scene, be used for test distributed agreement The offline fault-tolerance of node, the exception that can be constructed under distributed node exception scene includes: point run on distributed node Cloth application process is killed, CPU on distributed node power down and distributed node (Central Processing Unit, Central processing unit) damage etc..In the present embodiment, rehearsal scene can be designed according to the purpose drilled extremely, reality scene The failure of middle appearance all can serve as rehearsal scene in the case where drilling conditions permit extremely.
Specifically, the exception that the available rehearsal scene being locally located of distributed node needs the exception constructed corresponding Script file loads the exception that exception script file construction meets above-mentioned exception-triggered opportunity.In fact, in step S304 In, after the network message by above-mentioned link transmission is cached according to preset exception-triggered opportunity, institute's structure in step S306 The exception made can closely conform to above-mentioned exception-triggered opportunity.
In one embodiment, it can be being preset on distributed node by drilling terminal when monitoring feature message The rehearsal scene of required construction, distributed node can be according to the rehearsal scenes of the required construction of setting, and construction meets different The exception of normal trigger timing.In some embodiments, the rehearsal scene of setting may include multiple, it is, distributed node is supervised The exception of required construction may include multiple when measuring feature message, can be improved the efficiency drilled abnormal scene.
In one embodiment, the anomalous structure method of above-mentioned distributed protocol is further comprising the steps of: eventually by rehearsal End is being arranged network message feature, setting exception-triggered opportunity and is being arranged when monitoring feature message on each distributed node The rehearsal scene of required construction.
As shown in fig. 6, being mentioned by disposing the application on each distributed node by rehearsal terminal in one embodiment The timing diagram of the anomalous structure device of the distributed protocol of confession.Abnormal rehearsal is needed before construction drills scene referring to Fig. 6 Executor disposes the anomalous structure device of distributed protocol by drilling terminal on each distributed node.It needs to illustrate It is that the sequencing for disposing the anomalous structure device of distributed protocol on each distributed node is not restricted, only needs Rehearsal terminal can pass through another network link normal communication with each distributed node after the completion of disposing.
In step S306, the rehearsal scene on distributed node is arranged on demand, and cacoplastic mode is also can With what is be arranged on demand, distributed node can notify other distributed node constructions to meet the exception on exception-triggered opportunity, may be used also To meet the exception on exception-triggered opportunity in locally construction.
In one embodiment, according to preset rehearsal scene, construction meets the abnormal step tool on exception-triggered opportunity Body includes: to obtain pre-set rehearsal scene corresponding with feature message；Determine the exception of the required construction in the case where drilling scene； The corresponding construction instruction of determining exception is sent to the distributed node that need to be interacted；Construction instruction is used to indicate distributed node and exists Exception that is local construction determination and meeting exception-triggered opportunity.
Specifically, distributed node can determine link corresponding with this feature message, so after monitoring feature message Afterwards according to preset exception-triggered opportunity, persistent cache obtains pre-set grinder by the network message of link transmission Scape, under the rehearsal scene there are many exceptions of required construction, distributed node, which can be determined therefrom, is monitoring feature message When required construction exception, then need interactive distributed node to send for determining abnormal structure into distributed type assemblies Instruction is made, so that this distributed node that need to be interacted meets the different of exception-triggered opportunity in locally construction according to construction instruction Often.
For example, the first distributed node monitors the net after the network message A for receiving the transmission of the second distributed node When network message is characterized message, the first distributed node is with regard to the network message that transmits between persistent cache and the second distributed node B (i.e. by the message of the link transmission determined according to feature message), and pass through another network link to the second distributed node The corresponding construction instruction of the exception constructed required for sending, the second distributed node can be after receiving construction instruction, at this Ground structural anomaly.It is in the second distributed section in the present embodiment, it is possible to guarantee the exception constructed on the second distributed node It is constructed after o'clock sending network message A to the first distributed node.
As shown in fig. 7, for the schematic diagram of the anomalous structure method based on 3PC agreement in one embodiment.It, should referring to Fig. 7 Distributed type assemblies include coordinator's node 702, first participant's node 704 and second participant's node 706.Dotted line institute in Fig. 7 The step of mark, is performed when being the Distributed Application process progress network interaction on each distributed node based on 3PC agreement The step of step, solid line is identified is the step of method provided herein executes.
Referring to Fig. 7, network message feature is arranged by drilling terminal in rehearsal executor abnormal first on coordinator's node, The network message feature of setting is used to detect the CanCommit response message of second participant's node transmission, and abnormal rehearsal is held It is " triggering after receiving message " that passerby, which also passes through rehearsal exception-triggered opportunity for being arranged on coordinator's node of terminal, to be constructed Exception is " killing Distributed Application process ".From figure 7 it can be seen that receiving second participant's node feeding back in coordinator's node CanCommit response message after, monitor the received message and network message feature successful match, i.e., the message is spy Message is levied, since exception-triggered opportunity is " triggering after receiving message ", which will be transferred to local by coordinator's node Start the persistent cache not network message including this feature message after Distributed Application process, that is, caching generate to It is sent to the PreCommit message of second participant's node.Then coordinator's node notifies the second ginseng by another network link With the exception of person's joint structure " killing Distributed Application process ", second participant's node after receiving the notice, kill by execution The instruction of dead local Distributed Application process, and the notice to run succeeded to coordinator's node feeding back.In this way, being achieved that logical Crossing coordinator's node, reliably construction meets the exception on exception-triggered opportunity on second participant's node.
In one embodiment, according to preset rehearsal scene, construction meets the abnormal step tool on exception-triggered opportunity Body includes: to obtain pre-set rehearsal scene corresponding with feature message；Determine the exception of the required construction in the case where drilling scene； In exception that is locally construction determination and meeting exception-triggered opportunity.
Specifically, distributed node can determine link corresponding with feature message when monitoring feature message, according to Preset exception-triggered opportunity starts the network message that persistent cache passes through the link transmission, then obtains pre-set rehearsal Scene, under the rehearsal scene there are many exceptions of required construction, distributed node, which can be determined therefrom, is monitoring feature report Then the exception of required construction when literary meets the exception on exception-triggered opportunity in locally construction.
As shown in figure 8, for the schematic diagram of the anomalous structure method based on 3PC agreement in another embodiment.Reference Fig. 8, Network message feature, the network report of setting is arranged by drilling terminal in rehearsal executor abnormal first on second participant's node Literary feature is used to detect the CanCommit response message of second participant's node transmission, and abnormal rehearsal executor, which also passes through, to drill Practicing the exception-triggered opportunity that terminal is arranged on second participant's node is " triggering after sending message ", and the exception to be constructed is " killing Distributed Application process ".From figure 8, it is seen that generating in second participant's node for CanCommit message After CanCommit response message, monitors the CanCommit response message and network message feature successful match, i.e., should CanCommit response message is characterized message, and since exception-triggered opportunity is " triggering after sending message ", coordinator's node will The message is sent to after coordinator's node and starts the persistent cache not network message including this feature message, that is, is slow Deposit the PreCommit message of coordinator's node transmission.Then second participant's node is held according to the rehearsal scene of setting locally Row kills the instruction of Distributed Application process, that is, the structural anomaly after sending CanCommit response message, in this way, just real The exception for reliably constructing on second participant's node and meeting exception-triggered opportunity is showed.
S308 releases the caching to the network message by link transmission, and the network of transmission buffer after coming into force extremely Message.
When the exception of construction is in the exception that distributed node locally constructs, distributed node can directly determine that exception is No to come into force, abnormal when notifying the exception of another distributed node construction that need to be interacted when construction, then distributed node can be with Obtain the notice that the exception of distributed node feedback comes into force.Specifically, after the exception of construction comes into force, distributed node is no longer Caching by the network message of determining link transmission, and by the network message cached by the link transmission of above-mentioned determination extremely Corresponding another distributed node.
In the present embodiment, the network message buffered to the caching of network message and transmission is released, can be simulated After the exception of construction enters into force, can the Distributed Application process that run on distributed node continue it is anticipated that normal hand over Mutually.
For example, in Fig. 7, coordinator's node after receiving second participant's node feeding back anomalous structure and successfully notifying, The PreCommit message for being sent to second participant's node of caching is sent to second participant's node.Due to the second ginseng Be killed with the Distributed Application process run on person's node, if there is not exception in first participant's node, according to point Expected results of the cloth agreement under this abnormal scene, second participant's node cannot be corresponding to coordinator's node feeding back PreCommit response message (i.e. ACK message), first participant's node is in the PreCommit for receiving the transmission of coordinator's node The step of " write redo, undo log, lock resource, execute operation but do not submit " is needed to be implemented when message, and saved to coordinator Point feeding back ACK message.If actual result not it is anticipated that, such as second participant's node still fed back it is corresponding PreCommit response message, or fed back the message of other mistakes or first participant's node is not carried out and " writes Redo, undo log, lock resource execute operation but do not submit " the step of, also not to coordinator's node feeding back ACK message, Then the distributed type assemblies in explanatory diagram 7 dependent on distributed protocol cannot normally handle this exception of construction, need to improve base In the application program that the distributed protocol is realized.
For another example, in fig. 8, caching is obtained after the exception that confirmation locally constructs comes into force in second participant's node The PreCommit message that coordinator's node is sent, due to the Distributed Application process that is run on second participant's node by It kills, if exception does not occur in first participant's node, according to expected results of the distributed protocol under this abnormal scene, respectively Distributed node should be operated normally according to distributed protocol, for example, second participant's node cannot be to coordinator's node feeding back Corresponding PreCommit response message (i.e. ACK message), first participant's node are receiving the transmission of coordinator's node The step of " write redo, undo log, lock resource, execute operation but do not submit " is needed to be implemented when PreCommit message, and to Coordinator's node feeding back ACK message.If actual result not it is anticipated that, in explanatory diagram 8 dependent on distributed protocol point Cloth cluster cannot normally handle this exception of construction, need to improve the application program realized based on the distributed protocol.
The anomalous structure method of above-mentioned distributed protocol can effectively construct any one abnormal scene, realize Accurately and reliably triggering is abnormal under some exception-triggered opportunity.When monitoring feature message, the corresponding chain of feature message is determined Road, and according to preset exception-triggered opportunity, persistent cache passes through the network message of the link transmission, then drills according to preset Practice scene, construction meets the exception on exception-triggered opportunity immediately, and persistent cache can be with by the network message of the link transmission Guarantee that the exception of construction can accurately come into force on preset exception-triggered opportunity.After coming into force extremely, so that it may release immediately To the caching of network message and the network message of transmission buffer.This point is based on since feature message can be set as any one on demand Therefore the network message of cloth agreement accurately and reliably can construct any one possible anomalous field to the distributed protocol Scape avoids the very high problem of random configuration exception scene repeatability, substantially increases cacoplastic efficiency.
In one embodiment, after coming into force extremely, the caching to the network message by link transmission is released, and transmit The network message of caching includes: to release the caching to the network message by link transmission after coming into force extremely；It obtains local slow The network message to be received deposited；Alternatively, sending the network message to be sent of local cache to the distributed node that need to be interacted； Method further include: obtain the response results that each distributed node is directed to network message generation by drilling terminal；Response results are used The energy in the case where drilling scene of the Distributed Application process on each distributed node based on distributed protocol is determined in instruction rehearsal terminal No normal operation.
Specifically, after the exception of construction comes into force, distributed node can be released to the link by determining in step 302 The network message of transmission, including network message to be received and network message to be sent.When the network message of caching is waiting When the network message of receipts, then the network message to be received of local cache is obtained by the Distributed Application process of local runtime, When the network message of caching is network message to be sent, then by the Distributed Application process of local runtime by the net of caching Network message is sent to other distributed nodes that need to be interacted, and the response knot for the network message can be generated in each distributed node Fruit, rehearsal terminal can determine the distribution realized on each distributed node based on distributed protocol according to the response results of acquisition Application process can be it is anticipated that reliably working under the rehearsal scene of construction.If cannot, illustrate Distributed Application process mesh Before cannot normally handle the exception of construction, if can, illustrate that Distributed Application process can be operated normally when occurring extremely.
