Embodiment
The present invention lay particular emphasis on realize SNMP Agent (foreground agency) side warning information receive, handle, preserve, report and with function such as background synchronization, be elaborated below in conjunction with the technical scheme of accompanying drawing to the preferred embodiment of the present invention.
As shown in Figure 1, of the present inventionly comprise: alarm source module 101, foreground alarm management module 102, SNMP proxy module (SNMP Agent) 103, MIB module 104, backstage SNMP Manager module 105, background net management center 106 based on snmp protocol alarm and control system overall framework.
Alarm source module 101, this part is to belong to managed devices in the system, can have a plurality of alarm source modules in a network system.Alarm source module 101 is used for the alarm information of collection network system, and the alarm information that produces is sent to foreground alarm management module 102 according to the unified message interface.
Foreground alarm management module 102 is responsible for carrying out the detection of respective handling and alarm passage to receiving warning information (comprising alarm information, alarm recovery message and alarm notification message), and preserves warning information at foreground system, for the AM/BAM system synchronization.When described warning information need report background system, the alarm information reporting that will call after SNMP proxy module (SNMP Agent) 103 will be handled was given background system.Foreground alarm management module 102 possesses alarm information and handles, recovers and support the backstage query function, and background system is handled and reported to the alarm information, alarm recovery message, the documentary whip message that are about to 101 generations of foreground alarm source module.Guarantee under the normal condition alarm information, alarm recovery message, documentary whip message be delivered to the backstage possess real-time and succession, accurately do not have omit, not false-alarm, AM/BAM consistency, and abnormal conditions such as are overflowed in the alarm pond can handle.
Foreground alarm management module 102 also is used for warning information is controlled.After receiving warning information, whether judge this alarm for repeating alarm, if for repeating alarm, then the alarm data before the deletion sends alarm clearing to background system, at the new alarm data of original location storage, sends new alarm information to background system; If not repeating alarm, judge earlier whether the alarm pond full, if the alarm pond is full, then abandon new alarm data, if the alarm pond less than, preserve alarm data, send alarm information to the backstage.After receiving alarm recovery message, at first the corresponding alarm data of search in alarm pond, foreground if can find, is just deleted this node from the alarm pond, sends alarm recovery message to background system then, and recovering type is " normal alarm clearing ".After receiving alarm notification message, alarm notification message is numbered, calls corresponding TRAP interface then and send.
Backstage SNMP Manager module 105 is snmp management station ends, is responsible for intercepting reporting of foreground TRAP message, initiates SNMP GET and SET and asks to the foreground.After the TRAP message of alarm report is received by backstage SNMP Manager module 105 management stations, TRAP message is carried out dissection process, revert to alarm message packet and be transmitted to background net management center module 106.
Background net management center module 106 is responsible for the backstage related work, after receiving the alarm message packet that backstage SNMP Manager module 105 reports, carries out respective handling, resolves warning content and is shown to the user.
Other report with notice reporting and alarm report flow process similar as alarm clearing.
As shown in Figure 2, the processing procedure of foreground alarm management module 102 warning information is as follows:
Step S201 carries out initial work after alarm management module 102 starts.
Step S202 after receiving warning information, distributes new alarm code AID.
Step S203 searches in the alarm chained list, judges that whether this warning information is for repeating alarm.
The foundation of judging is alarm code+warning position+alarm additional information (to a specific alarm code).If this warning information is for repeating alarm, execution in step S212; Otherwise, execution in step S204.
Step S204 if not repeating alarm, judges earlier whether current idle chain meter pointer is empty, if be empty, and execution in step S205; Otherwise, execution in step S206.
Step S205 if current idle chain meter pointer is empty, illustrates current alarm pond full (normal condition can not occur, because the alarm pond can empty the part alarm after having expired immediately), carries out abnormality processing, then abandons new warning information.The alarm pond can be provided with size according to actual conditions, and the pond generally can not occur alarming expires.
Step S206 if current idle chain meter pointer is not empty, preserves the alarm pond position of warning information to the sensing of idle chain gauge outfit.
Step S207, background system sends a warning message.
Step S208 is inserted into alarm chained list head to current idle chain gauge outfit.
Step S207 judges whether the idle chain gauge outfit is idle chained list tail, if execution in step S210, otherwise execution in step S211.
Step S210 if the idle chain gauge outfit is idle chained list tail, illustrates alarm Chi Yiman, does abnormality processing.
Step S211 revises the idle chain gauge outfit, points to next node.
Step S212, if this warning information is for repeating alarm, then the alarm data before the deletion sends alarm recovery message to background system.
Step S213 is at the original new alarm data of location storage in alarm pond.
Step S213 to head, sends new warning information to this node link to background system.
As shown in Figure 3, foreground, the synchronous implementation procedure of backstage alarm data are as follows:
Because the mutual measured snmp protocol in native system foreground and backstage, therefore one of design is used for the synchronous list structure of AM/BAM in the MIB storehouse.The AM/BAM data in synchronization is with the transmission of SNMP MIB table object form.Initiate synchronously in both cases on the backstage: the one, and synchro timer is overtime; The 2nd, when detecting, the alarm passage finds that initiating synchronization request when the AM/BAM alarm data has packet loss acts on behalf of to the foreground.The AM/BAM synchronization mechanism guarantees AM/BAM alarm data unanimity, accomplishes not false-alarm, not false dismissal.
The synchronization mechanism of AM/BAM system guarantees AM/BAM alarm data unanimity, accomplishes not false-alarm, not false dismissal.In the time of synchronously, background system is initiated a synchronization request and is given the foreground, the alarm code of current all alarm records that foreground system inquiry oneself alarm pond is returned, the alarm record (passing through alarm code) in the alarm record that background system relatively returns and oneself alarm pond.If the alarm (foreground has the backstage not have) of omission is arranged, then sends out this warning information of acquisition request to the foreground; If false-alarm (foreground does not have the backstage to have) is arranged, then delete this alarm record in the alarm pond, backstage.
Step S301 if the background system synchro timer is overtime, triggers SNMP Manager105 and sends synchronization request to foreground system.
Step S302 receives foreground system alarm pond alarm code (AID) data set.
Obtain the critical field of all alarm records of alarm pond, foreground, this critical field should be to discern the critical field of every warning information, is generally alarm code AID+ warning position.
Step S303, the foreground alarm code AID that traversal is returned.
Step S304 judges whether current alarm sign indicating number AID is present in alarm pond, backstage, if there is execution in step S305; Otherwise execution in step S306.
Step S305, corresponding alarm code AID tagging in this alarm pond, backstage.
Step S306 if current alarm sign indicating number AID is not present in alarm pond, backstage, is the backstage false dismissal, to the corresponding warning information of this alarm code of foreground queries AID.
Step S307 behind the corresponding warning information of this alarm code AID that receives the foreground feedback, is saved in alarm pond, backstage, and to this warning information tagging, then, execution in step S303 judges whether next alarm code AID is present in alarm pond, backstage.
Step S308, traveled through foreground alarm record set after, travel through the alarm record in alarm pond, backstage again.
Step S309 judges whether mark of this warning information.
If mark, execution in step S310, otherwise execution in step S308.
Step S310 if also have record not beat mark, illustrates that the foreground does not have this alarm, belongs to false-alarm, deletes this warning information from alarm pond, backstage, reports corresponding alarm recovery message to give the background net management center.
Traveled through alarm pond, backstage, this subsynchronous end.
Step S311, last, all background synchronization variablees of initialization comprise that synchro timer sets, alarm pond, backstage mark resets etc., withdraws from synchronously.
As shown in Figure 4, alarm passage detection implementation procedure is as follows.
Owing to the native system alarm report adopts SNMP TRAP mechanism, bottom transmits based on the UDP connectionless protocol, therefore has the situation of unreliable, the possible packet loss of transmission.In order to improve the reliability of alarm information transmission, prevent that the information reporting that causes owing to the data packet loss is untimely, inaccurate, remedy this defective by the method that provides a regular passage to detect.In order to improve the reliability of transmission, the corresponding notification message of one side, packing transmission as far as possible, minimizing the number of transmissions; Message such as the alarm information that sends for foreground system, alarm notification are added up on the other hand, and the backstage is also added up alarm information, the alarm notification of receiving.AM/BAM can be arranged message by certain rule (such as adding up since 1) numbering, if interrupting appears in the message numbering that receive on the backstage, has packet loss to take place when just meaning intermediate transport.For alarm, because foreground system has preservation, so adopt the method for synchronization to guarantee data consistency.For notice, whether the AM/BAM system is retransmitted by relatively numbering to have to lose.
Step S401, behind timer expiry, background system (is backstage SNMP Manager module 105 at this) sends SET command messages (Set Request) and gives foreground system (is SNMP proxy module 103 at this), and the variable of binding in the SET command messages comprises: the paid-in alarm information number in backstage, alarm recovery message number and notification message number.
The backstage is provided with an alarm passage and detects timer, and the message bag that several variable records are received is set.For the alarm of receiving, alarm recovery message, statistical items of every receipts adds 1; For notification message, whenever receive the numbering of this notification message of record.
Step S402, foreground system is resolved the SET command messages, obtains the paid-in alarm information sum of background system, alarm recovery message sum, and the notification message numbering.
Step S403, foreground system is preserved at the SET command messages of receiving, and return response message (Set Response) is given background system, binding foreground statistical information in the response message.
After foreground system is received this message, return one and reply, alarm information number, alarm recovery message number and notification message number that the binding foreground has sent.Foreground system can know all with background system whether whether alarm information receives consistent with transmission, exist the packet loss and the packet loss order of severity like this.
Step S404, the statistical information that transmit the backstage on the foreground is handled, and checks the notification message numbering that background system is received, by relatively drawing the numbering of losing bag in the transmission.Foreground system is removed from buffer queue for sending successful notification message, and whether check has the notification message of losing, if having then find repeating transmission from formation.
Step S405 resends notification message (the Alarm Inform Trap) packing of losing.
If the notification message that reports is found on the foreground packet loss is arranged, can from buffer queue, extract repeating transmission,, from buffer queue, remove by checking its numbering for paid-in alarm notification message according to Alarm ID.
After step S406, background system received and reply, whether the alarm information that the inspection foreground system has sent, recovery message count are preserved with oneself consistent.
Step S407 when background system is checked through alarm information, recovers the inconsistent of message count and oneself preservation, then sends synchronization request to foreground system.
Step S408, foreground system query warning pond, SNMP Agent103 alarms request alarm data in pond by foreground alarm management module 102 to the foreground.
Step S409, alarm data is returned in alarm pond, foreground, comprising the Alarm ID of current all alarm records of being preserved.
Step S410, the alarm process is returned the syn ack data, wherein comprises alarm data.
Foreground system returns the syn ack data to background system, wherein comprises the Alarm ID of current all alarm records.
The alarm record (passing through Alarm ID) in the alarm record that background system relatively returns and oneself alarm pond if the alarm (for example foreground system has the backstage not have) of omission is arranged, is then sent out this warning information of acquisition request to the foreground; If false-alarm (foreground does not have the backstage to have) is arranged, then delete this alarm record in the alarm pond, backstage.
