Based on the above-mentioned characteristic of view networking, one of the core concepts of the embodiments of the present invention is proposed, inquiry terminal will include The inquiry request of link query argument is respectively sent to view networked server and link simulations server, can be with depending on networked server It is inquired to obtain corresponding first data link structural information according to the link query argument, meanwhile, link simulations server It can be inquired to obtain corresponding second data link structural information according to the link query argument, due to the first data link knot Structure information is the transmission path of data actual transmissions process in autonomous networks, since the actual transmission process of data is more multiple It is miscellaneous, if loss or mistake that link sets up order occurs, it will lead to data transfer path and mistake, and the second data link knot occur Structure information is the transmission path of data desired transmission process in autonomous networks, is based on autonomous networks structure and interrelated logic It obtains, therefore the data transfer path is an ideal data transfer path.By comparing the first data link structure Information and the second data link structural information, so that it may judge whether data have occurred mistake during actual transmissions, thus Check out the mistake of data link.

Referring to Fig. 5, the step of showing a kind of data link querying method embodiment based on view networking of the invention stream Cheng Tu, this method can be applied in view networking, can specifically include:

Inquiry request including link query argument is sent to the view the Internet services by step 501, the inquiry terminal Device and the link simulations server.

Referring to Fig. 6, a kind of structure chart of the data link inquiry system based on view networking of the present invention, the data are shown Link inquiry system includes view networked server 10, link simulations server 20 and inquiry terminal 30, wherein view the Internet services Device 10 can receive the inquiry request that inquiry terminal 30 is sent, and according to the inquiry request, calculate data source nodes to number According to the data transmission link of sink nodes, data can also be obtained each according to the routing table lookup for managing data transmission link Transmission link in a thin cloud, so that it is determined that data link structural information, obtains the first query result；Link simulations server 20, the corresponding relationship being stored between preset link query argument and data link structural information, the link simulations service Device 20, can be according to the inquiry request, by link query argument and institute after receiving the inquiry request that inquiry terminal 30 is sent It states corresponding relationship to be matched, determines the corresponding destination data link structural information of the link query argument, obtain second and look into Ask result；Inquiry terminal 30 is to provide the input of link query argument in data link inquiry system for user, and view networking is taken The equipment that the query result that business device 10 and link simulations server 20 obtain compares, in the present invention, if actual transmissions mistake There is no mistakes for journey, then the data link structural information in the first query result should be with the data-link in the second query result Line structure information is consistent, and may thereby determine that the state of the data link is that data link is correct, inquiry terminal 30 is defeated The state of the data link is that link is correct out；If actual transmissions process has occurred certain mistakes, in the first query result Data link structural information should be with the data link structural information in the second query result it is inconsistent, may thereby determine that The state of the data link is data-link error, and the state that inquiry terminal 30 exports the data link is link error.

In this step, when client has the demand of inquiry data link, inquiry request can be sent out by inquiry terminal Sending to view networked server and link simulations server, the inquiry request includes link query argument.

Specifically, the link query argument can be one of following five kinds of link query arguments:

Parameter 1: the global equipment number of data source nodes；

Parameter 2: the global equipment number and sub- equipment number of data source nodes；

Parameter 3: global equipment number, sub- equipment number and the channel number of data source nodes；

Parameter 4: the overall situation of the global equipment numbers of data source nodes, sub- equipment number, channel number and data sink nodes Equipment number, sub- equipment number, channel number；

Parameter 5: global equipment number, sub- equipment number and the channel number of data sink nodes.

Wherein, data source nodes are the sender of data in autonomous cloud, and data sink nodes are the reception of data in autonomous cloud Side.

Specifically, it is that equipment is entering that equipment number, which is used for positioning device, global equipment number in the business of autonomous networks, A unique equipment number of the whole network being assigned to when net, global equipment number is one 20 10 binary digits, is divided into 4 Section, every section is one 5 10 binary digits, such as 12345-67890-33333-88888；The sub- device number of equipment be It is if being connected with two sub- equipment than equipment, then described for the number of area's Molecular Devices when equipment is connected with multiple sub- equipment The sub- equipment number of two sub- equipment is respectively 1 and 2；Channel number is that have multiple channels that can send multichannel data in sub- equipment When, for distinguishing the number in different channels, such as channel there are two sub- equipment, then the channel number in described two channels is respectively 1 With 2.

In embodiments of the present invention, the inquiry request can be with are as follows: " user requires inquiry data link structural information, chain Road query argument are as follows: the global equipment number of data source nodes is 12345-67890-33333-88888, sub- equipment number is 1, channel number 1 ".

Optionally, after step 501, step 502 can be performed, step 503 also can be performed.

Step 502, it is described depending on networked server according to the link query argument for including in the inquiry request, determine First query result, and first query result is added in the response for the inquiry request.

In this step, the inquiry request comprising link query argument that inquiry terminal is sent is received depending on networked server, The first query result is assured that according to the link query argument, and first query result is added to for inquiry In the response of request, and then the response for inquiry request is back to inquiry terminal.

Specifically, networked server is regarded in autonomous cloud when configuration data link, it can be according to data source nodes and data The equipment number of sink nodes calculates transmission link of the data in autonomous networks, meanwhile, depending on networked server in management data When transmission link, transmission path of the data in each thin cloud can be recorded by routing table, the list item of each routing table is by 256 A byte composition, each byte correspond to the routing iinformation of some network interface in thin cloud, and the position of byte in the table entry is exactly The logic port address of corresponding network interface indicates that corresponding network interface does not receive this when the numerical value of certain byte is 0 in list item Circuit-switched data indicates that the interface is this circuit-switched data when the numerical value of certain byte is the logic port address of corresponding network interface in list item Data source header in corresponding thin cloud, i.e., the data of other interfaces are directly or indirectly from the interface in thin cloud.List item In certain byte numerical value be other values when, indicate the data on the interface from the corresponding network interface of this numerical value.Table 1 is One example of routing table:

Byte location	1	3	5	10	30	100	150
								Byte content	5	5	10	10	10	30	30

Table 1

The first row indicates which byte in 256 bytes in table 1, and the second row indicates the numerical value at corresponding byte, not The other byte values listed are 0.

Assuming that the expression of table 1 is routing iinformation of some data in 0x78 thin cloud.

According to definition could be aware that data source header of the data in 0x78 thin cloud from logic port address be 10 Interface belonging to equipment X, then this circuit-switched data by equipment X be forwarded to logic port address be 5 interface belonging to equipment Y and It is 1 and 3 that this circuit-switched data is forwarded to logic port address again by equipment Z belonging to the interface that logic port address is 30, equipment Y Two equipment belonging to interface, equipment Z are then forwarded to this circuit-switched data belonging to the interface that logic port address is 100 and 150 Two equipment.

It therefore, in embodiments of the present invention, can be according to inquiry request depending on networked server after receiving inquiry request In link query argument determine that the link is inquired according to the data transfer path recorded in networked server routing table of view Transmission path of the corresponding data of parameter in autonomous networks, i.e. the data link structural information of the data, obtain the first inquiry As a result.

Step 503, the link simulations server are according to the link query argument for including in the inquiry request, really Fixed second query result, and second query result is added in the response for the inquiry request.

In this step, the inquiry comprising link query argument that link simulations server receives that inquiry terminal is sent is asked It asks, the second query result is assured that according to the link query argument, and first query result is added to and is directed to In the response of inquiry request, and then the response for inquiry request is back to inquiry terminal.

Specifically, after each equipment networks in autonomous networks, so that it may determine the equipment for including in autonomous networks and each Communication connection relationship between equipment, and then the corresponding data link structural information of various link query arguments can be calculated, Because the data link structural information is calculated based on autonomous networks structure and interrelated logic, the calculating process not by The influence of various factors during data actual transmissions, therefore can inquire to obtain one relatively just by link simulations server True data link structural information.

Step 504, the inquiry terminal extract first query result and the second inquiry knot from the response Fruit.

In this step, inquiry terminal receives the inquiry request comprising the first query result that view networked server is sent The inquiry request response comprising the second query result that response and link simulations server are sent, and mentioned from the response Take out the first query result and the second query result.

Step 505, the inquiry terminal compare first query result and second query result, determine data-link The state on road.

In this step, the first query result and the second query result that inquiry terminal is received by comparison, so that it may Determine the state of data link.

Specifically, first query result is according to link query argument in step 502, according to view networked server The query result that routing table obtains includes the transmission road of data actual transmissions process in autonomous networks in the first query result Diameter, if loss or mistake that link sets up order occurs, will lead to data biography since the actual transmission process of data is complex Mistake occurs for defeated path, and corresponding data link structural information is also mistake.

And second query result is obtained according to link query argument by link simulations server in step 503 Query result, include the transmission path of data desired transmission process in autonomous networks in the second query result, due to the biography Defeated path is to be calculated based on autonomous networks structure and interrelated logic, therefore the data transfer path is an ideal number According to transmission path, corresponding data link structural information is also a relatively correct result.

Further, the first query result and the second query result are compared, due to the first query result and second The corresponding query argument of query result be it is identical, therefore, if there is no mistake, the first query results for actual transmissions process In data link structural information should be one with the data link structural information in the second query result obtained by calculation It causes, may thereby determine that the state of the data link is that data link is correct；If certain mistakes have occurred in actual transmissions process Accidentally, then the data link structural information in the first query result should be with the data in the second query result obtained by calculation Link structure information be it is inconsistent, may thereby determine that the data link state be data-link error.
