The described network failure of epimere detects in the client, the work of physical layer detection module, link layer detection module, network layer detection module, application layer detection module, automatic repairing module, system safety module all is to trigger promptly passive triggering by the request from user's interface module.These modules also can adopt the mode that initiatively triggers to come work, promptly trigger processing such as its separately detection, reparation by the cycle timing that sets in advance.
In addition, when fault detection module comprises two or more detection module, promptly comprise in physical layer detection module, link layer detection module, network layer detection module and the application layer detection module any both or both when above, detection trigger process mutually between each detection module: receive from subscriber interface module and/or the fault detect request that self regularly triggers by a detection module wherein; Receive each detection module of fault detect request, do not deal with when fault and other each detection module have all detected when detecting, when detecting fault and also have other detection module to detect, do not send the fault detect request to a detection module that detects, and when detecting fault, detection module will not deal with, and the detection of current fault detection module is handled and also just is through with.Briefly: when fault detection module comprises two detection modules, at first, wherein a detection module receives from subscriber interface module and/or the fault detect request that self regularly triggers, detect and also have a detection module to detect when not detecting fault, then send the fault detect request to this detection module that detects; This detection module detects after receiving the fault detect request, and when not detecting fault, all detection modules in the current fault detection module all detect, does not then deal with, and current fault detection module is finished all and detected processing.
Because physical layer detection module, link layer detection module, network layer detection module and application layer detection module difference corresponding physical layer, link layer, network layer and application layer are four protocol layers from low to high, therefore best detection mode begins to detect one by one each protocol layer from low to high from lowest protocol exactly.Be exactly specifically: at first by the physical layer detection module regularly and/or detect when the fault detect request that receives from user's circle module, when the physical layer detection module does not detect any fault, just send the fault detect request to the link layer detection module; When not detecting any fault, the link layer detection module send the fault detect request again to the network layer detection module; When not detecting any fault, the network layer detection module send the fault detect request again to the application layer detection module; Do not do any processing when using when detection module does not detect any fault layer by layer, finish whole testing process.
In addition, each detection module in the fault detection module also can send the fault restoration request to automatic repairing module when detecting fault, indicate it that physical layer, link layer, network layer or application layer are repaired.More than several work triggering modes of each module can distinguish separately and use, also one or more triggering mode wherein can be combined use.Such as: the system safety module can be started working when receiving system safety information updating request: whether transmitting system security information update request is brought in the detection system security information to Central Management Server needs renewal work, also will begin transmitting system security information update request when arriving timing cycle.Because various triggering modes is a lot of in conjunction with situation, this paper just enumerates no longer one by one, but all within protection range of the present invention.
Based on system shown in Figure 1, below in conjunction with Fig. 2 and Fig. 3 the inventive method is described in detail, and the operation principle of system of the present invention is further elaborated.
Fig. 2 is the example flow chart of all kinds of processing in the inventive method.Network of the present invention connects fault detection method and comprises the three major types processing: one, fault detect and reparation comprise that step 201 is to step 205; Two, customization fault detect strategy comprises that step 211 is to step 214; Three, the failure cause statistics comprises that step 221 is to step 223.This method also further comprises a class aid in treatment, and the system safety information updating comprises that step 231 is to step 234.More than four classes handle and will independently carry out respectively, this paper only handles this four class and is shown in the same accompanying drawing, but does not limit the execution sequence of this four classes processing.
When carrying out fault detect and repairing, carry out following steps:
Step 201～step 202:PC machine user sends the fault detect request to fault detection module by subscriber interface module, and fault detection module is carried out fault detect by the indication of this fault detect request, when detecting network connection fault, and execution in step 203.
Wherein, fault detection module can be this any one or combination in any of: physical layer detection module, link layer detection module, network layer detection module, application layer detection module.The man-machine interface that the user provides by subscriber interface module can be selected which layer in physical layer, link layer, network layer and the application layer is carried out fault detect, subscriber interface module will send the fault detect request to corresponding detection module by user's indication then, such as: if the user selects physical layer and link layer are carried out fault detect, then subscriber interface module will send the fault detect request respectively to physical layer detection module and link layer detection module.
In addition, fault detection module self also can be provided with timer, regularly starts process fault detection by the pre-configured fault detect cycle.Because fault detection module can be: this any one or combination in any of physical layer detection module, link layer detection module, network layer detection module, application layer detection module, so physical layer detection module, link layer detection module, network layer detection module and application layer detection module can be provided with timer separately and detect by the fault detect cycle.
Step 203: the detection module that detects network connection fault in the fault detection module will be analyzed failure cause, return failure cause information and give subscriber interface module, subscriber interface module will be for the user shows failure cause information on PC, so that the user takes the necessary measure to fix a breakdown according to failure cause.Fix a breakdown for further facilitating the user, fault detection module also can further be returned and be used to point out the indication of fixing a breakdown of the method for fixing a breakdown to give subscriber interface module, and the user can solve current network by this indication of fixing a breakdown and connect the problem that occurs.
Step 204: the user sends the fault restoration request to automatic repairing module according to the failure cause that shows from subscriber interface module, which that network is connected this fault restoration request will indicate partly repair, such as: ICP/IP protocol of indication configuration network layer or the like.
Step 205: automatic repairing module is repaired corresponding faulty component according to the fault restoration request that receives.
Wherein, detect client for network failure, the detection content that its fault detection module relates to is various, such as: physical layer detects the detection that comprises network interface card and modulator-demodulator (Modem), and the network layer detection comprises ping test, DNS test or the like.And the network for narrow band access and broadband access method is connected, and the concrete detection content of physical layer, link layer, network layer, application layer has very big-difference again.Therefore, the user can select the fault detect strategy flexibly according to the characteristics of its network connection access way and self network connection setting.This fault detect strategy can be kept in the subscription data of operator, when the user uses network failure to detect client, need thereby detecting client, network failure could finish the configuration of faults itself measuring ability to the Central Management Server customization fault detect strategy of carrier side according to the fault detect strategy.When customization fault detect strategy, carry out following steps:
Step 211: the user sends fault detect strategy customization request to fault detection module by subscriber interface module, and this request comprises information such as user ID.
Step 212: fault detection module is transmitted the fault detect strategy customization request that receives and is given Central Management Server.Here, fault detection module also can initiatively send fault detect strategy customization request to Central Management Server when starting first.
Step 213: Central Management Server is determined the fault detect strategy that this user contracts according to the user ID in the fault detect strategy customization request, and returns this fault detect strategy and give fault detection module.
Step 214: fault detection module is finished self measuring ability configuration by the fault detect policy module that receives, such as: when the physical layer and the link layer detection of this fault detect strategy indication broadband access method, then fault detection module will be enabled the physical layer detection module and the link layer detection module of broadband access method.
When carrying out the failure cause statistics, carry out following steps:
Step 221～step 222: the user sends the request of failure cause statistics to fault detection module by subscriber interface module.Fault detection module connects failure cause to self detected network and adds up and obtain statistics.Wherein, fault detection module may comprise a plurality of detection modules, and the statistics of self will be added up and obtain respectively to each detection module synchronously, and the summation of the statistics of each detection module is exactly the failure cause statistics of whole fault detection module.
Here, fault detection module also can be provided with timer, starts the failure cause statistic processes by predetermined measurement period.
Step 223: fault detection module reports the failure cause statistics to the Central Management Server end, thereby operator can understand the network connection failure condition of each user terminal by Central Management Server, connects the fault solution so that formulate effective network.
When carrying out the system safety information updating, carry out following steps:
Step 231～step 232: the user gives the system safety module by subscriber interface module transmitting system security information update request.This system safety information updating request of this system safety module forwards is to the Central Management Server end.Here, this system safety information updating request portability current network fault detect client software version number and the virus base information of License Info or PC or operating system vulnerability database information of PC or the like.
Step 233: the Central Management Server end is according to the system safety information updating request that receives, the network failure of inquiry self-management detects client software version information or virus base information or operating system vulnerability database information or the like, determines whether the PC of current transmission request needs to upgrade these information.The retrieval system security information is given the system safety module when determine to need upgrading, this system safety information can for: network failure detects latest edition this shop or most current virus information or up-to-date operating system leak information or the like of client software.
Step 234: the system safety module is upgraded to network failure detection client software by the system safety information that receives or is upgraded the virus base of PC or upgrade operating system vulnerability database of PC or the like, finishes system safety information updating process.
