Detailed description of the invention
Below in conjunction with drawings and Examples, technical scheme is described in detail.
If it should be noted that do not conflict, each feature in the embodiment of the present invention and embodiment can be combined with each other, all within protection scope of the present invention.Although it addition, show logical order in flow charts, but in some cases, can be to be different from the step shown or described by order execution herein.
Embodiment one, a kind of method of Hierarchical Network Management System system queries managed device state, including:
Managed devices at different levels, to Network Management Equipment uploaded state block, the most only report a type of status block, and carry the type of institute's uploaded state block upper giving the correct time；
Described Network Management Equipment is after receiving the status block that a managed device reports, by the wherein entrained type that class record is this status block reported of this managed device.
In a kind of alternative of the present embodiment, described method also includes:
Network Management Equipment issues status inquiry command to managed device, carries the type of inquired about status block in described status inquiry command；Wherein, the type of inquired about status block is the one being previously defined in type in this Network Management Equipment, this managed device status block.
During in each managed device, the polytype of status block can be previously defined in configuration information or other file of Network Management Equipment；If newly-increased managed device or the type of status block, then can update described configuration information or other file.If according to pre-defined, the status block of certain managed device only has a type, then Network Management Equipment can not send status inquiry command.
In a kind of alternative of the present embodiment, in order to allow managed device uploaded state at different levels time the type of carrier state block and allow Network Management Equipment can issue the status inquiry command of the type carrying inquired about status block, the communication protocol between Network Management Equipment and managed device at different levels can be revised.The type of status block is increased in the status block that managed devices at different levels report.The order that Network Management Equipment issues increases status inquiry command, including the type of inquired about status block.
The form of managed device uploaded state blocks at different levels can as shown in Figure 4, including protocol header, status block type, status block payload, agreement tail；Wherein, status block type is new field, is the status block of any type for mark.
Network Management Equipment issues the form of status inquiry command can be as it is shown in figure 5, include protocol header, command block type, command block payload, agreement tail；Wherein, command block type is for representing the type of inquired about status block.
Assume that, in an example, certain grade of equipment has 3 block state informations, be respectively type be the status block of A, type be the status block of B, type be the status block of C；Then three kinds of message formats during uploaded state block are as shown in Figure 6, essentially identical with the protocol format shown in Fig. 4, and status block type the most therein is respectively A, B, C.
Network Management Equipment is handed down in the communication protocol of subordinate equipment to increase status inquiry command, in upper example, the difference of the type according to the inquired about status block wherein carried has three kinds of command formats, as shown in Figure 7, essentially identical with the protocol format shown in Fig. 5, simply command block type therein is respectively A, B, C, represent respectively for query type be the status block of A, query type be the status block of B, query type be the status block of C.
In a kind of alternative of the present embodiment, managed device, when receiving the status inquiry command of Network Management Equipment, preserves this status inquiry command；If the status inquiry command received before existing in this managed device, then receive before replacing by the status inquiry command newly received.
Described managed device at different levels specifically includes to the step of Network Management Equipment uploaded state block: when arriving state delivery time (the such as start time in the cycle that state sends), if there is the status inquiry command preserved, then report the status block of specified type in this status inquiry command；Otherwise report default status block；Generally can be using most important status block most basic for this equipment as default status block.
So when Network Management Equipment does not sends status inquiry command, subordinate equipment can only report a certain status block；When receiving the status inquiry command from Network Management Equipment, more fixing report the status block specified in this status inquiry command.So Network Management Equipment has just been grasped managed device at different levels and has been reported the initiative of which bulk state, thus ensures that Network Management Equipment can collect all status informations of managed device at different levels.
Assume that certain grade of most basic most important status block of equipment is status block A, then using status block A as default status block.When arriving state delivery time, uploaded state starts, if not receiving the status inquiry command that Network Management Equipment sends, this equipment can a uploaded state block A.If receiving the status inquiry command of Network Management Equipment, then judge status block type to be inquired about according to the command block type in this status inquiry command, if inquiry status block A then uploaded state block A；If inquiry status block B then uploaded state block B；If inquiry status block C then uploaded state block C；If not being, then the command block type not having in this equipment in status inquiry command being described, carrying out reporting an error or not sending out status block.Flow process is as shown in Figure 8.

Network Management Equipment when the scheduled time arrives maybe when the type of this status block reported of certain managed device received and last time are different, from the type of the status block of this managed device being previously defined in this Network Management Equipment, select to be positioned at the type after the type that the last time reports, as the type of inquired about status block, send status inquiry command to this managed device.
If because the scheduled time arrive status inquiry command to be sent, then the last type that reports be arrive this scheduled time before the type of status block that receives for the last time；If because status block change and status inquiry command to be sent, the then the last type that type is this status block reported reported.
In Network Management Equipment, the order of each status block is given tacit consent to or is ranked in advance.
In other alternative of the present embodiment, Network Management Equipment can also use other to send the strategy of status inquiry command, and different managed devices can be used different strategies；Such as the managed device having is used the strategy " sending status inquiry command when the type of the arrival scheduled time or status block changes and inquiring about next status block " in above-mentioned alternative；The managed device having then can be used strategy based on status information, Network Management Equipment analyzes the preset state of managed device, when some state finding managed device changes, needs to know other state, send the status block known required for status inquiry command inquiry；After receiving the status block needing to know, it is also possible to retransmit the status block that a status inquiry command inquiry is preset.Use which kind of strategy, the relation between managed device status block determine.Between managed device status block, relation is not tight, when importance is suitable, can be selected for the strategy in above-mentioned alternative.When some status block of managed device is inessential, it is not required to report constantly, and when depending on default or other status block, strategy based on status information can be used；In other instances, it is also possible to both are used in mixed way.Practical solution is not limited to the above-mentioned strategy mentioned, it is also possible to designed, designed strategy as required.So Network Management Equipment can fully be grasped managed device and report the initiative of which kind status block.
Such as in an object lesson, flow process is as it is shown in figure 9, when Network Management Equipment enters after reception state, first receive status block, assume that managed device first sends default status block always, then, before timing arrives, Network Management Equipment can judge that the status block received is identical with last time；The most do not send order and just terminate reception state.After the scheduled time arrives, status block can be first received when Network Management Equipment enters back into reception state, then judge that the scheduled time arrives, therefore the status inquiry command of the next status block of inquiry is sent, if that this sends is status block A/B/C, then send the status inquiry command (assuming predefined putting in order as status block A, B, C) of inquiry status block B/C/A.
In this alternative, it is to prevent managed device state reporting slow that status block changes the main purpose said the word again, and Network Management Equipment inquiry is fast, the order that so the multiple many of meeting is unnecessary.The length of described timing is chosen relevant with the Cycle Length of managed device state reporting, preferably more than the Cycle Length of state reporting.
In one alternative of the present embodiment, managed device in one Hierarchical Network Management System system can be arranged to different reporting policies, than if any managed device only report default status block when confiscating the status inquiry command of Network Management Equipment, other managed devices report all types of status blocks the most in turn when confiscating the status inquiry command of Network Management Equipment.
In an alternative of the present embodiment, described method can also include: on managed devices at different levels, when the time span (that is: reporting the moment time span to current time of this status block from first time) reporting a certain piece of non-default status block exceedes very first time threshold value or number of times exceedes frequency threshold value, revert to report default status block (such as can abandon preserved requirement and inquire about the status inquiry command of other type state block, maybe this status inquiry command be designated and do not use；So after arriving the state reporting moment, default status block will be reported).
In an alternative of the present embodiment, described method can also include: on Network Management Equipment, if sending the time span (that is: the time span from the moment of last time transmission status inquiry command to current time) not occurring chunk change after status inquiry command more than the second time threshold, retransmission state querying command the most again.
