Whether the server detection network equipment breaks down, and mainly by network adapter, into network, all-network is set
Preparation send inspection to instruct, if the communication of all-network equipment is normal, it is determined that network apparatus in networks does not break down, otherwise, really
Determine the network equipment to break down in network.That is, server by utilizing network adapter, timing all-network device broadcasts
Inspection instruction is sent, the all-network equipment in network is detected.If the communication of all-network equipment is normal, it is determined that network
The middle network equipment does not break down, otherwise, it determines the network equipment to break down in network.
Specifically, server, for any bar network link in network, the terminal device with the bottom of network link is
Starting point, each network equipment into network link sends inspection instruction, until receiving feedback command.Server will
The network equipment of the next stage of the corresponding network equipment of feedback command is determined as the network equipment of failure to be confirmed.Server later
If the feedback for the all-network equipment that the network equipment for not receiving the next stage of the network equipment corresponding with feedback command is connected
Instruction, then be determined as the network equipment to break down for the network equipment of failure to be confirmed.From the terminal device of bottom-layer network by
Layer retrospect network state, diagnostic instruction is sent in a manner of poll, identification judgement is carried out to returning the result, traces back to always without reason
The network equipment of barrier.
For example, as illustrated in fig. 2, it is assumed that network totally 5 layers of structure, it is assumed that network equipment C0 failure, under the network equipment
For all-network equipment all in abnormal communication states, detection method is as follows:
First link: inspection sequence is E0, D0, C0, B0.Terminate after to normal network equipment B0.
Article 2 link: inspection sequence is E1, D0, C0, B0.Terminate after to normal network equipment B0.
Article 3 link: inspection sequence is E2, D1, C0, B0.Terminate after to normal network equipment B0.
Then other chain circuit detecting methods are same as above.
All communication abnormality network equipments under network equipment C0 reversely trace back to network equipment B0, and network equipment C0 is true
It is set to the network link of failure to be confirmed.Each of the links testing result can navigate to network equipment C0 and break down, and meet all
It, i.e., can be with the net of failure to be confirmed after the mutual verifying of the normal network equipment of polyisocyanate after the breakdown judge state consistency of the network equipment
Network equipment is determined as the network equipment to break down.If the network equipment quantity under failed network device is greater than 100, to improve
Speed is traversed, then only judges the interlocking proofing state of 100 network equipments, shields the fault message of other network equipments.
By the above method reversely layer-by-layer multichannel diagnosis, parallel multi-thread various dimensions are counter to be deduced, with network equipment event
Barrier positioning is mutually authenticated, and shields the network equipment lower layer network equipment failure letter for having obtained verifying.
If network equipment failure reparation is completed, or is broken down without the network equipment, still can not receive on terminal device
Data are passed, then the source of failure may be data link failure or terminal equipment failure.
Server continues to determine whether data link breaks down, specifically, server into network data Layer it is all
Data communication services adapter sends test instruction, if the non-returned data of data communication services adapter, it is determined that data link
It breaks down.Server is after judging no network link failure, the communication test thread of log-on data link, carries out data link
Troubleshooting.Test instruction is issued by server, sequentially returns to return data in each service adapter program of data plane.Such as
Fruit is abnormal, and the abnormal mark of modification data link table identifies the data communication services adapter fails of this data link, reported
Barrier.By the diagnostic method, failure can be accurately positioned to data communication services adapter, determine that data link breaks down.
If above-mentioned data link reparation is completed or no data link layer breaks down, and still can not be received terminal and be set
It is standby to upload data, then show the terminal device itself fail, can determine that the terminal device breaks down, notifies work people
Member overhauls the terminal device.
