Complete the comparison work of several ten million data.
Preferred: message is XML format, and key-value pair is the key-value pair that XML tag and label substance are converted into；
It is all apparently the message content for being parsed and being used in principle for the message by iterative testing,
The format and content verification adaptable to message progress and receiving node is needed then to carry out subsequent analysis；It is past in the prior art
Toward the verification mode using general fixation between node, cannot with network node at that time the case where be adapted, thus by problem
It has been left in subsequent analysis, or even the application layer for making problem rise to upper layer, user experience greatly reduces.When in problem
It is often difficult to parse when being raised to upper layer, the reason of problem；
Step S2: format and content verification is carried out to request message；Specifically: it obtains message identification and searches corresponding format
File is verified, is verified based on format of the format check file to message；Content authentication text is determined based on format check file
Part verifies content based on content authentication file；
What format check file and content authentication file were to discriminate between out, preferred: wherein format check file is XML
Scheme format；The format check file and content authentication file are maintained in local verification space；This is locally verified
Content in space needs regularly to be updated, and the mode of update is network update or two kinds of hardware update；Hardware update
It needs to obtain in such a way that hardware accesses；The local verification space is encryption storage；Using network update mode plaid matching
Formula verification file is updated, and regularly obtains the format check file from network monitor server, and place it in fixation
Local verification space in；Content authentication file is updated using hardware update mode, content authentication file will be stored with
Storage device access network nodes in, by the storage of updated content authentication file into local verification space；It is former in covering
Before content authentication file, raw content is verified into file and new content verification file is compared, is carried out in different situations
Covering storage；Preferred: the comparison is to be compared version, abstract, file name etc.；The network monitor server is used
In the monitoring of offer content authentication file and progress duplicate message anomalous event；
A kind of safety and simple way are to carry out the mapping in local verification space, by the visit in the local verification space
Ask that address of cache is the storage device of hardware mode access, the storage device is led to by fixed mode access network nodes
The mapping for crossing access address, when needing access stencil verification file or content authentication file, access can be directed to hardware
The storage device that mode accesses, so that network node more flexible simply can carry out verifying the update of file, simultaneously
Also ensure the adaptability and safety of verification file.
Format check file includes structural element and content element, wherein structural element, for describing which in message
A element and when occurring, which type of attribute content element is used to describe element with；Based on content authentication text
The verification of part progress content；Wherein, content element is the index of content authentication file, can find phase by the content element
The content authentication file answered；In this way, so that content and format check separate, on the one hand increase it is safety-type, separately
On the one hand make to change content authentication relatively more, for the more message checking of verification content, it is literary that format check can be reduced
The times of acquisition of part reduce because of the verification various expenses of bring；Preferred: format check file is XML Scheme lattice
Formula；Different type network receiving nodes is to format and requires variant, and content authentication may be implemented by separated mode
Extension；
Format and content verification is carried out to request message, including (can also can be with message standard one based on XML Schema
Rise and issue) carry out format checking.Format check will be carried out to the message received, refused for being unsatisfactory for giving for call format
Processing is effectively isolated message transmitting party failure situation to realize.
It is preferred: message being carried out based on format check file to carry out content authentication file before or while format check
Preloading；Specifically: the mark based on format check file is preloaded；Based on format check file acquisition and the report
Text verifies relevant all the elements and verifies file, and by the verification file load of described all the elements in spatial cache；Pass through this
The access mode of mode and the hardware access of sample combines, and will not reduce processing speed.
It is preferred: the re-organized of clear text is carried out before the format and content verification for carrying out message；It is specific: will
The clear text received is stored in the order received in clear text queue, is obtained in clear text queue
The index set of the content authentication file of each clear text in all clear texts；It is similar between computation index set
Degree, the index for being adjusted so that similarity is high for carrying out the sequence of clear text processing gather the place of corresponding clear text
The reason time is close, conversely, the processing time that corresponding clear text is gathered in low the indexing of similarity is kept off；It is preferred: only
The mark of clear text is saved in clear text queue only to reduce the time overhead from re-organized；
Similarity between the computation index set, specifically: by index element identical in two index set
Quantity is as the similarity between two index set；Cause when not considering that set element is less when calculating similarity really include
And the higher similarity of bring, when index element is less, corresponding content authentication file is less, at this point, carrying out content school
The expense for testing the preloading of file is also few；
It is preferred: the re-organized of clear text to be carried out using sliding window, to the report within the scope of sliding window in queue
Text carries out re-organized, after the completion of the message within the scope of current sliding window mouth is by re-organized, slides sliding window in the queue
One sliding window length carries out re-organized to continue the message within the scope of next sliding window；Wherein, the processing
Message queue is round-robin queue；The size of the sliding window is preset value, the length of the preset value and processing message queue
And the quantity of clear text is related, and the adjustment of the preset value can be carried out according to the two relevant length and quantity；
Step S3: it carries out the monitoring of duplicate message anomalous event and reports；Specifically: carry out independent repeated events monitoring and company
Continuous anomalous event monitoring；
It is described to carry out independent repeated events monitoring, specifically: it obtains and identifies identical duplicate message, the number of duplicate message
Whether it is more than or equal to and repeats threshold value, independent repeated events occurs if it is, determining, obtain the transmission path of all duplicate messages
To constitute transmission path set, the mark of the duplicate message and its transmission path set are reported；The quantity mistake of duplicate message
The network node failure in transmission path is mostly often implied, at this time by that can determine for failure reporting for transmission path set
Position provides effective clue；
Preferred: network monitor server receives duplicate message mark and its transmission path set, by transmission path set
In path merge with constitute weighting transmission figure, wherein transmission figure in node be path in each network node,
The weight of network node is the number that network node occurs in the paths；Scheme to carry out network node monitoring based on the transmission, it is right
Wherein the high node of weight carries out emphasis monitoring；
The node high to weight carries out emphasis monitoring, specifically: the expansion that transmission figure is carried out based on weighted value, to warp
The each network node crossed in widened transmission figure is monitored；Wherein, big to the monitoring granularity of network node in former transmission figure
In the monitoring granularity for the network node for belonging to widened transmission figure but being not belonging in former transmission figure；
The expansion that transmission figure is carried out based on weighted value, specifically: each node in transmission figure is successively expanded,
For a network node, it is directly connected to node based on the determination of its weighted value is corresponding with its weighted value, is directly connected to save by described
It puts and its is directly connected to path and increase in widened transmission figure；It is corresponding with weighted value to be directly connected to node to determine, so that
Its widened range of the higher node of weighted value is bigger, and the range monitored in this way is more extensive, so that relatively accurate expands inspection
The range of survey；When weighted value is higher, transmit in figure the fault incidence may more light, so needing to carry out widened monitoring；
The monitoring granularity include monitor the size of interval of events, monitoring type number and monitoring dynamics size
Deng；
The progress continuous abnormal event monitoring, specifically: based on duplicate message Annual distribution situation and verification situation into
The anomalous event of row duplicate message monitors, and the specific exceptions event that will test reports；Wherein, Annual distribution situation describes weight
The case where multiple message changes over time, verification situation describe duplicate message not by the type of above-mentioned verification, such as: do not pass through
Content authentication etc.；
The anomalous event monitoring that duplicate message is carried out based on duplicate message Annual distribution situation, specifically: it will repeat
The time and quantity that message occurs are fitted to obtain matched curve, and the matched curve is compared with first kind curve
To determine whether matched curve and first kind curve are similar, if similar, report without anomalous event；Otherwise, if not
It is similar, then continue to judge whether matched curve and the second class curve are similar, if similar, carry out continuous abnormal event and report,
Otherwise continue the subsequent anomalous event monitoring that duplicate message is carried out based on verification situation；Wherein first kind curve is normal
Duplicate message the case where occurring, the case where this kind of duplicate message changes over time often and network topology structure, network section
The type of point is relevant, is not need to carry out individually if the appearance situation of duplicate message is similar with this kind of curves
Monitoring and report；And the second class curve is the duplicate message of specific abnormal condition；In the prior art often all
Without the abnormality detection based on Annual distribution situation, and there is situation and is excluded in the normal duplicate message of non-team, weight
Multiple messaging system detection effect is bad；
The anomalous event monitoring that duplicate message is carried out based on verification situation, specifically: it determines within the scope of the set time
The number of check errors occurs, if the number is more than upper limit threshold and corresponding anomalous event is concentrated in less than first
In the network node of quantity, then anomalous event is sent to the network node less than the first quantity, otherwise taken to network monitor
Business device sends anomalous event；Wherein: the first quantity is less quantitative value, is preset value；It is only focusing only in verification seldom
When in range, the efficiency for doing monitoring can be proposed by carrying out local solution.Here, upper limit threshold, first quantity etc. are preset values；
The above description is only a preferred embodiment of the present invention, thus it is all according to the configuration described in the scope of the patent application of the present invention,
