Description
Technical field
The present invention relates to network management and monitoring system, specifically, relate to a kind of poll implementation method and device of the network management and monitoring system when using Multimodem (MODEM) to carry out dialcom.
Background technology
As shown in Figure 1, utilize the MODEM dial mode to realize that webmaster with the General System framework of the network management and monitoring system of communication between devices is in the prior art: the webmaster end is finished and the communicating by letter of watch-dog by the communication server.Usually, a plurality of webmaster end MODEM are set on the communication server, webmaster end MODEM 1 as shown in Figure 1, webmaster end MODEM 2 ..., webmaster end MODEM N, thereby each webmaster end MODEM can set up communicating by letter of webmaster end and this equipment at the moment equipment MODEM that dials.Because some equipment need carry out authentication to dialed number, promptly these equipment only accept to use the dialing of the webmaster end MODEM of its authentication dialed number to it.Fig. 1 has showed this relation, and promptly equipment 11 ... equipment 1m only accepts the dialing of webmaster end MODEM 1, equipment 21 ... equipment 2m only accepts the dialing of webmaster end MODEM 2, equipment N1 ... equipment Nm only accepts the dialing of webmaster end MODEM N.It will be appreciated that parameter m only illustrates that a webmaster end MODEM can not constitute the restriction to number of devices at the difference different equipment that dials constantly, it does not show that the number of devices that each webmaster end MODEM can dial is identical.
Before webmaster end MODEM on the communication server and equipment communicate, need put through link by dialing, this process of putting through approximately needs 20-30 not wait second, putting through the back just can communicate, as long as this call duration time is generally 1-2 second, puts through and hang up very short relatively, and sign off is hung up link again, wait for that MODEM hardware resets, this process also needed about 5 seconds.As seen, in whole communication process, the biggest factor that influences its time is the dialing time of MODEM, it causes two MODEM to send the packet of equal number, deadline may differ greatly, there is bigger difference in the first in the MODEM time of putting through, it two is to send these packets, the number of devices that needs to connect may be different, if for example entire packet all sends to same equipment, put through so once just passable, if each packet will send to different equipment, then each equipment all will be put through and be hung up, the time will be very long.
Above-mentioned temporal loss in the ordinary course of things may not can cause too much influence, yet when webmaster need carry out poll to watch-dog, owing to need the equipment of poll huge, may cause serious time loss.
Not only there are a large amount of losses of MODEM dialing time in the polling mode of prior art, also exists the problem that can not dispatch the MODEM resource of the communication server effectively.As shown in Figure 2, the key step of the routing strategy of the communication server of the prior art is:
One, the communication server receives the order that the webmaster end sends over;
If the authentication number of appointment be empty in two orders, and to have dialed number in the communication resource of the communication server be the MODEM of this authentication number, the wait transmit queue of this MODEM of this order adding; Otherwise find out the minimum MODEM of the medium formation to be sent of all MODEM the inside order, this order is added the wait transmit queue of this MODEM.
The routing strategy of this communication server, be to carry out according to handling MODEM idle condition constantly and packet authentication situation, having no idea to understand in advance follow-up which packet in addition will handle, also have no idea to understand in advance which MODEM and handle than very fast, which MODEM handles slow.Idle condition owing to each MODEM in the situation of not taking all factors into consideration device authentication, the communication server causes in the process of poll, some MODEM may occur and be too busy to do it, and idle situation but appears in some MODEM that can send the corresponding data bag.
For example: webmaster end MODEM 1 receive in a large number do not need the packet of authentication after, at this moment must webmaster end MODEM the 1 authorization data bag that sends just arrive, owing to do not need the packet of authentication to occupy the time that webmaster end MODEM 1 sends in a large number, then cause these authorization data bags to wait in line.And the free time may appear in webmaster end MODEM 2 at this moment, and it can send those no authorization data bags of waiting in line to send in webmaster end MODEM 1.
And for example: during beginning, webmaster end MODEM 1, webmaster end MODEM 2 have received the packet of equal number, webmaster end MODEM 1 may send all waiting data package very soon, and webmaster end MODEM 2 processing speeds are slow, also have a lot of packets etc. to be sent, and wherein comprising the no authorization data bag that some can be sent by webmaster end MODEM 1 probably, the result is that the MODEM resource does not make full use of, and further causes poll to need a lot of times.

Embodiment
Contrast accompanying drawing and the present invention is further elaborated below in conjunction with embodiment.
The webmaster end carries out poll when handling, and needs to send the mass data bag, if according to general processing mode, sends to the communication server with at random order, though the communication server can be handled, need expend a large amount of time.
The invention provides a kind of poll implementation method of optimization, it considers that mainly MODEM resource of the prior art is owing to the wasting of resources that does not have effectively scheduling to cause, effectively the MODEM resource is dispatched by method of the present invention, improve the utilance of MODEM resource, thereby improve the efficient of webmaster poll.On the other hand, consider in monitoring communications that therefore main time loss improves the efficient of webmaster poll at the MODEM during dialing from the angle that reduces MODEM dialing number of times.
The poll implementation method of the specific embodiment of the invention as shown in Figure 3, its key step is:
S1, webmaster end package to all equipment that need carry out poll;
S2, webmaster end send the request of inquiry MODEM communication resource information to the communication server;
After S3, the communication server receive the request of webmaster end inquiry MODEM communication resource information, obtain the information of each MODEM of webmaster end in real time, comprise MODEM quantity ModemCount, the dialed number TelNumber of each MODEM correspondence has waited in line the number of devices DeviceCount that communicates in each MODEM transmit queue;
S4, the communication server send to the webmaster end to communication resource information;
S5, webmaster end carry out following processing according to the communication resource information that obtains:
Set up no authentication formation and authentication formation, as a preference of the present invention, can be according to MODEM communication resource information, each MODEM is set up an authentication subqueue, the quantity of authentication subqueue equals MODEM quantity ModemCount, waited in line the number of devices DeviceCount that communicates in the corresponding dialed number TelNumber of related its corresponding MODEM of each authentication subqueue and this MODEM transmit queue, such processing will offer convenience for follow-up command lookup;
S6, webmaster end distribute each polling order successively, distribution principle is: if the authentication number of polling order corresponding device (promptly this equipment receives only the dialing of this dialed number) is identical with the dialed number of some MODEM communication resources, this order is added corresponding authentication subqueue below authentication formation;
Otherwise,, then should order to add no authentication formation if polling order does not belong to any one authentication subqueue; Be appreciated that no authentication formation herein can comprise two kinds of orders: a kind of is the order that does not need the authentication number, though another kind then is that the authentication number is arranged, with all different order of authentication number on the communication server;
After S7, polling order have assigned, no authentication formation and each authentication subqueue are sorted, the principle of ordering is: the order of identical device dialed number is connected one, be that the identical polling order of authentication number of corresponding device is grouped as in formation separately and adjoins each other, finish up to the order ordering of each formation.
It is the transmission set-up procedure of a polling order that said process can be regarded as, through this transmission set-up procedure, will help finishing following order and send processing procedure, continues that below order is sent processing procedure and describes:
S8, at the webmaster end counter UsabledModemCount=0 is set, this parameter will be used for reflecting the MODEM number of the free time in the communication server;
The webmaster end will carry out following processing to each authentication subqueue below the authentication formation:
S9, as number of devices DeviceCount＞2 of waiting in line to communicate by letter of the MODEM of this subqueue correspondence (because after obtaining the DeviceCount of communication resource correspondence, may very fast all orders will send and finish, therefore this sentences 2 rather than 1 Rule of judgment as the MODEM state), carry out step S10; Otherwise, carry out step S11;
S10, UsabledModemCount is added 1, it should be noted that not send the order of this formation this moment, because the order that corresponding MODEM to be used such as communication service end communicate does not also dispose;
If orders to be sent such as authentication subqueue of S11 also has are carried out step S12, otherwise are carried out step S13;
S12, begin backward, the order of identical device dialed number as Management Information Base, is sent the top Management Information Base of formation, then the order that sent is deleted, at last UsabledModemCount is added 1 from the formation foremost;
S 13, continuation are handled next authentication subqueue and are disposed up to whole authentication subqueues;
Can understand from above-mentioned explanation: in DeviceCount＞2 o'clock, illustrate that this corresponding MODEM is in busy state, in the processing of present embodiment, only be then, and do not send the polling order of this MODEM correspondence webmaster end counter UsabledModemCount+1.If this is because send to the communication server with order this moment, because the communication server is in busy state, polling order can only continue to wait in the wait transmit queue of this MODEM and can not obtain very soon handling, and the webmaster end can't be monitored this situation, therefore can not effectively judge the poll progress.And adopting the mode of this enforcement, the webmaster end can effectively be monitored the poll progress by the polling order that does not send.In DeviceCount ≤=2, be that MODEM is when being in idle condition, then judge earlier whether order to be sent is arranged in the authentication subqueue of this MODEM correspondence etc., if have, although then being described, this MODEM is in idle condition, but need to send the order in its authentication subqueue, then send the order in the authentication subqueue of this MODEM correspondence this moment, and if the authentication subqueue of this MODEM correspondence of webmaster end counter UsabledModemCount+1 do not waited order to be sent, do not change UsabledModemCount.
As seen, processing through above step S9 to S13, polling order can send the order in its authentication subqueue when MODEM is in the free time, simultaneously UsabledModemCount can reflect and be in busy state and MODEM the quantity idle but order of needs transmission authentication.
If S14 counter UsabledModemCount is less than MODEM quantity ModemCount, illustrate that then some the MODEM communication resource in the communication server not only enters idle condition, and can utilize these idle MODEM to send those to be kept at the order that does not need authentication in the no authentication formation, promptly satisfy down in this condition, carry out step S15, otherwise jump to step S16.
S15, deduct UsabledModemCount with ModemCount, obtain idle MODEM quantity I dleModemCount, to no authentication formation, begin backward from the formation foremost, the order of identical device dialed number is a Management Information Base, the top IdleModemCount group command of formation is sent, then the order that sent is deleted;
Be appreciated that from above-mentioned explanation UsabledModemCount is the counter of webmaster end, ModemCount is the counter (webmaster is by inquiry, the numerical value that the communication server returns) of communication service end.Suppose that the communication server has 10 MODEM, during the webmaster inquiry, the communication server returns these 10 MODEM inquiries DeviceCount (the corresponding DeviceCount of each Modem) constantly, and corresponding have 10 authentication subqueues at the webmaster end.If last 2 authentication subqueues have been empty, and corresponding DeviceCount＜=2 (illustrate that the webmaster end does not have data to send, the communication server is empty substantially simultaneously, after the above-mentioned processing of process, the value of UsabledModemCount is exactly 8, illustrate that these two MODEM are idle condition, so just can send by these two MODEM from the packet of 2 equipment of no authentication formation taking-up.(because the routing strategy of the communication server, the communication server can be automatically according to the most idle order the allocation of packets of these two equipment in these two MODEM waiting lists.
S16, each subqueue below no authentication formation and the authentication formation is judged,, carried out step S17 if all be empty; Otherwise, carry out step S18;
S17, polling order send and finish, and no longer carry out subsequent treatment, withdraw from handling process;
S18, webmaster end send the request of inquiry MODEM communication resource information to the communication server; The communication server obtains MODEM communication resource information and returns to the webmaster end; The webmaster end is according to the MODEM communication resource information that receives, upgrades and preserves the numerical value of having waited in line the number of devices DeviceCount that communicates in the MODEM transmit queue; Return step S8, the transmission cycle that the webmaster end begins a new round carries out polling order and sends.
Because handling the communication of an equipment, the communication server needs certain hour, so can begin in the new round transmission cycle, be that the above-mentioned processing of returning step S8 is provided with a stand-by period before, the stand-by period setting should suit, because if the stand-by period is too short, can cause the communication resource situation of the frequent query communication server end of webmaster end, if the time is oversize, possible communication server end MODEM is idle, the webmaster end does not also have new data to send in the past, causes the communication service end MODEM wasting of resources.Therefore the stand-by period can be set at and wait for for 30 seconds (wait for that communication server end finishes the call duration time with an equipment, the dialing procedure about comprising in 20 seconds, transfer of data is hung up).
Sum up poll implementation method of the present invention, its main advantage is:
In order to improve the poll efficient of webmaster end, polling order to be sorted in formation, the order of accomplishing to issue same equipment once sends after dial-up success and finishes a large amount of loss of time that avoiding repeats to dial causes;
Exist equipment component to need authentication in the system, equipment component does not need authentication, during the webmaster poll, classify according to the authentication situation earlier, when sending packet, introduce the notion in transmission cycle, first at first query communication service of each transmission cycle MODEM resource situation is known which MODEM free time, which MODEM is busy, if MODEM is busy, this transmission cycle will be ignored this MODEM, the preferential simultaneously packet that needs authentication that sends, after having sent the authorization data bag, if also have MODEM to be in idle condition, just send relevant device quantity data bag, thereby made full use of the MODEM resource.
In order more accurately to judge communication resource waiting list quantity, after the order of transmission one-period, the webmaster end obtains up-to-date communication resource waiting list quantity from the communication service end again.
By above processing, accomplished that poll finishes before, make full use of the MODEM resource, save the repetition dialing time may occur in a large number, reach the purpose that improves poll efficient.
Poll implement device of the present invention, as shown in Figure 4, comprise the webmaster end and the communication server, the webmaster end is provided with scheduler module, authentication formation and does not have the authentication formation, authentication formation and no authentication formation are assigned polling order according to the resource information of each modulator-demodulator of the communication server that obtains by following principle: if the authentication dialed number of polling order corresponding device is identical with the dialed number of arbitrary modulator-demodulator of the communication server, then this polling order is distributed in the authentication formation; Otherwise this polling order is distributed in no authentication formation;
Scheduler module is taken turns in the transmission cycle at each, according to the resource information of each modulator-demodulator of the communication server that gets access to, judges the state of each modulator-demodulator of the communication server, and sends polling order until end of polling(EOP) by following principle:
If the state of certain modulator-demodulator is idle, judge the authentication dialed number polling order identical that whether has corresponding device in the authentication formation with the dialed number of this modulator-demodulator, if have, send the authentication dialed number of the one group of corresponding device polling order identical to the communication server with the dialed number of this modulator-demodulator, otherwise, send one group of polling order that does not have the authentication subqueue to the communication server; Finish epicycle and send the cycle.
Above-mentioned each send a group of cycle and send order, its composition can constitute like this: to the processing of sorting of the polling order in authentication formation and the no authentication formation, the polling order that corresponding device is identical sorts together, forms this group command by scheduler module.
As preferred implementation of the present invention, authentication formation shown in Fig. 4 comprises a plurality of authentication subqueues, each authentication subqueue is corresponding one by one with each modulator-demodulator of the communication server, and the polling order that the authentication dialed number of corresponding device is identical with the dialed number of a certain modulator-demodulator of the communication server is assigned to corresponding authentication subqueue.
Above content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
