Topic.With reference to the accompanying drawing, it elaborates to the embodiment of the present application.In the absence of conflict, following embodiment and implementation
Feature in example can be combined with each other.
Please refer to Fig. 1, server 10 provided by the embodiments of the present application can be used for at least two in network environment to
The communication link of measurement equipment is detected, wherein and the quantity of measurement equipment to be checked can be configured according to the actual situation, such as to
The quantity of detection device can be two or more.
Server 10 can establish communication connection by network and the first Devices to test 20 to carry out data interaction, server
10 can also establish communication connection by network and the second Devices to test 30 to carry out data interaction.First Devices to test 20 and
Pass through physical connection between two Devices to test 30, it usually needs the communication chain between two equipment is detected on the basis of physical connection
Whether road is connected to.
In the present embodiment, Devices to test (for example, first Devices to test 20, the second Devices to test 30) can be routing
Device, interchanger etc..Network may be, but not limited to, cable network or wireless network.
Referring to figure 2., chain circuit detecting method provided by the embodiments of the present application can be applied to above-mentioned server 10, by taking
Business device 10 executes or realizes each step of chain circuit detecting method, and this method can be suitable for detection Ethernet interface, wide area network connect
The communication link of mouth, expands the scope of application of link detecting.Wherein, server 10 is based on preset network protocol and realizes data
It issues and collects, to realize link detecting.Preset protocol is the association of the collection that can be realized facility information, configuration issued
View comprising but be not limited to snmp protocol, NETCONF agreement etc..
Each step of chain circuit detecting method shown in Fig. 2 will be described in detail below:
Step S210 sends to the first Devices to test 20 and indicates that the communication connection status of its first interface is cut by first state
It is changed to the first instruction of the second state.
In the present embodiment, server 10 can according to need sends instructions under two equipment detected, by instruct come
Change the communication connection status of equipment interface.For example, the equipment that can store two equipment detected in server 10
Interface message table, being then based on default network protocol by the interface message table, an equipment sends instruction thereto.Wherein, it is sent out
The equipment for sending instruction is the first Devices to test 20, and another equipment is just the second Devices to test 30.
Understandably, the communication connection status of the interface of Devices to test generally includes communication connection connected state or communication link
Connect off-state.First state is state of the Devices to test before the instruction of reception first, and the second state receives for Devices to test
State after first instruction, the second state are the state different from first state.First state and the second state can be according to realities
Border situation is determined.For example, if first state is connected state (communication connection connected state can be referred to as UP), the second shape
State is just off-state (communication connection off-state can be referred to as DOWN).If first state is off-state, then second
State becomes connected state.
That is, the first Devices to test 20 and the second Devices to test 30 be when carrying out link detecting, if with second to be measured
The first interface of 30 physical connection of equipment is UP, then the first Devices to test 20 is receiving the first instruction that server 10 issues
Afterwards, the communication connection status of first interface will will be switched to DOWM by UP.Similarly, if with 30 physics of the second Devices to test
The communication connection status of the first interface of connection is DOWM, then the first Devices to test 20 is in receive that server 10 issues the
After one instruction, the communication connection status of first interface will be switched to UP by DOWM, then observed in the second Devices to test 30
The interface equally changed occurs with the presence or absence of communication connection status.
Optionally, first state is communication connection connected state, and the second state is communication connection off-state, in step
Before S210, method can also include: to obtain the institute that first state is in the first Devices to test 20 and the second Devices to test 30
There is the interface message of interface, and generate the interface message table including total interface, wherein interface message includes the mark letter of interface
Breath and communication connection status.
Understandably, before step S210, server 10 can by preset network protocol (such as snmp protocol), to
All Devices to test of the server 10 communication connection send the request message collected for information, to collect and the server 10
The information of all Devices to test of communication connection, which includes device name, equipment identities mark, interface name, interface body
Part mark, communications status of interface etc., are then based on device name, interface name and the communications status of interface of Devices to test etc.
Information generates equipment interface information table as shown in Figure 3.Based on the interface message table, it can be used for detecting the first Devices to test 20
First interface communications status during change, occur in the second Devices to test 30 with the presence or absence of the communications status of interface
It is same to change.
Optionally, step S210 may include: based on interface message table successively choose the first Devices to test 20 in the
The interface of one state sends the first instruction as first interface, to the first Devices to test 20, includes first interface in the first instruction
Identification information.
In the present embodiment, server 10 can send the first instruction to Devices to test based on interface message table.For
The label for indicating to be transmitted across the first instruction can be set in interface through being transmitted across the first instruction, convenient for information interface
The interface without sending the first instruction in table continues to detect, to avoid there is missing inspection or repeating the case where detecting, thus
It is able to ascend the efficiency and reliability of link detecting.
Optionally, before step S210, method can also include the steps that configuring interface.Such as: according to
The corresponding link layer protocol of type configuration of the interface of one Devices to test 20 and the second Devices to test 30；Wherein, it first to be measured sets
The interface of standby 30 same type of 20 physics and the second Devices to test configures identical link layer protocol.
Link is carried out according to the type of interface to the total interface of 20 physics of the first Devices to test and the second Devices to test 30
Layer protocol configuration, for example, interface is ether interface, ether interface is inherently UP by its state after cable or optical fiber connection
, it does not need to carry out special configuration again.If interface is pos interface, when can encapsulate ppp protocol, configuration to pos interface
Clock, CRC check, in order to which interface can realize the change of communication connection status by instruction.If interface is CE1 interface, can
To divide channel creation interface, ppp protocol is encapsulated on the interface of creation, in order to which interface can realize communication link by instruction
Connect the change of state.
Step S220, during the communication connection status of first interface is switched to the second state by first state, judgement with
The of the second state is switched to the presence or absence of by first state in second Devices to test 30 of 20 physical connection of the first Devices to test
Two interfaces obtain judging result.
In the present embodiment, generally, if two Devices to test realize link connection by corresponding two interface, that
, if wherein the communications status of an interface is switched to DOWN by UP, then simultaneously, the communications status of another interface can also be sent out
Raw identical change, that is, its communications status also can be switched to DOWN by UP.That is, by changing the first Devices to test
Whether the communications status of 20 first interface detects and deposits in the second equipment then during the state changes of first interface
In the interface of identical change, the testing result of the communication link of two interfaces just can determine that out by its judging result.
Step S230 is based on judging result, and the first interface for obtaining the first Devices to test 20 is with the second Devices to test 30
It is no that there are the testing results of communication link.
Understandably, during the communication connection status of first interface is switched to the second state by first state, if with
There is the second interface that the second state is switched to by first state in second Devices to test 30 of one Devices to test, 20 physical connection,
So there are communication links with second interface for first interface, and the communication of communication link is normal.If with 20 object of the first Devices to test
The second interface for being not present in the second Devices to test 30 of connection and being switched to the second state by first state is managed, then first interface
With the communication abnormality of the communication link of second interface or communication link is not present.
After determining testing result, (interface message) can be identified according to interface identity and determines that the two of link connection connects
Then mouth detailed identification information can be arranged it for indicating normal communication, communication abnormality or the mark for having already passed through detection,
This two interface is detected to avoid repetition.
Optionally, method can determine testing result by the change of a communications status, can also connect to same
Mouth carries out the change of communications status twice to determine testing result, to improve the accuracy of testing result.For example, step S230 can
To include:
Show to obtain the identification information of second interface from the second Devices to test 30 there are when second interface in judging result；
The communication connection status for sending instruction first interface to the first Devices to test 20 is switched to the first shape by the second state
Second instruction of state, and believe from the mark that the second Devices to test 30 obtains the third interface for being switched to first state by the second state
Breath；When the identification information of second interface is identical as the identification information of third interface, obtain between first interface and second interface
There are the testing results of communication link；
Alternatively, in the identification information of second interface and the not identical identification information of third interface, obtain first interface with
The testing result of communication link is not present between second interface.
In the present embodiment, server 10 can be by instructing to the logical of the same first interface of the first Devices to test 20
Letter connection status is switched twice.Then it detects in the second Devices to test 30 and identical change occurs with the presence or absence of communications status
Interface.It is twice the second interface in the second Devices to test 30 (that is, generating state change twice is if existing twice
The same interface in second Devices to test 30), then also mean that between first interface and second interface there are communication link,
And the communication of communication link is normal.If during two next states change, having there is no there is a situation where identical change generations, or send out twice
The interface of raw identical change is not the same interface, it means that communication chain is not present between first interface and second interface
The communication abnormality of communication link between road or two interfaces.Based on this, switched by two next states to determine testing result,
The reliability and accuracy of testing result can be further increased.
It should be noted that when carrying out second and detecting, server 10 can be the into the second Devices to test 30
Two interfaces send instruction, then judge that the interface of identical change occurs with the presence or absence of state for the first Devices to test 20, and if it exists, and
The interface that the first Devices to test 20 changes in second of detection is exactly first interface (for example, the interface that two next states change
Identification information it is identical), then then thinking first interface, there are communication links with second interface, and the communication of communication link is just
Often.
Optionally, after step S230, communication link between first interface and second interface is characterized in testing result and is deposited
When, method can also include: that first interface information and second interface information are deleted from interface message table.
Understandably, if there are multiple Devices to test to need to carry out link detecting in interface message table, correspondence is had determined
Interface existing for communication link out can then delete its interface message from interface message table, in order to which server 10 continues pair
Other interfaces not detected continue to test, and are based on this, can help to be promoted to avoid repeating to detect identical two interface
The efficiency of detection.
Optionally, if in interface message table, the interface message including multiple Devices to test completes the first Devices to test 20
After detection with the second Devices to test 30, it can continue to carry out traversal detection to other Topology connections in interface message table, directly
Corresponding communication link and corresponding interface are determined to all Devices to test.For example, server 10 can continue to
Communication link between one Devices to test 20 and other Devices to test is detected, and certainly, the object continued to test is also possible to
Second Devices to test 30 is with other Devices to test or two different from its of the first Devices to test 20 and the second Devices to test 30
His Devices to test.Its process detected is referred to the detailed description of step S210 to S230, and which is not described herein again.
Referring to figure 3., citing is illustrated each step of above-mentioned chain circuit detecting method below:
The first step, link equipment to be found-interface message table generate: all devices (Devices to test, including first to
Measurement equipment 20 and the second Devices to test 30) on enable snmp protocol, generate that link is to be found sets according to the information of traversal equipment
Standby-interface message table, as shown in Figure 3.For example, in Fig. 3, the entitled DUT1 of Devices to test, interface entitled If1 are corresponding to connect
Mouth type is ether.The entitled DUT2 of Devices to test, the entitled If2 of interface, corresponding interface type are POS.
Second step, interface configuration distributing, concrete operations may is that for ether interface, connect it by cable or optical fiber
Its state is inherently UP afterwards, does not need to carry out special configuration again；For POS, E1 interface, PPP association can be encapsulated to it
View, configurable clock generator, CRC check realize that the state of interface is UP；For CPOS, CE1 interface, channel creation interface can be divided,
Ppp protocol is encapsulated on the interface of creation；For SA interface, interface clock rate is configured in DCE side, is sealed in DCE and DTE side
Fill ppp protocol.
Third step, the acquisition of interface communication connection status variation, which is divided into two processes, first is that being serviced by SNMP
Device 10 carries out shutdown operation (link opening operation) to equipment interface, issues interface to equipment using snmp protocol
Shutdown operation, such as by the IF1 interface shutdown of DUT1；Second is that obtaining the TRAP information of equipment and being parsed, obtain
Take the interface and facility information of stateful variation.
4th step generates direct-connected topological relation according to the TRAP information obtained in third step, as follows:
(DUT1)IF1--------IF2(DUT2)
5th step exists again according to topological relation by the IF1 interface no shutdown (link opening operation) of DUT1
The TRAP information that equipment is obtained on SNMP server 10, according to the UP information at both ends, parsing generates topological relation, raw with the 4th step
At topological relation be compared, think that the topological relation is correct if as the two, topological relation deposited to designated position, if
It is inconsistent then to repeat the 4th step, the 5th step.
6th step, however, it is determined that go out communication link connection between the IF2 interface in the IF1 interface and DUT2 of DUI1, then it can be with
The IF2 interface message in the IF1 interface message and DUT2 of the DUI1 of topological relation is had confirmed in sweep equipment information table, is kept away
Exempt from subsequent repetition and finds topology.
7th step checks the link between other routers in interface message table, repeats third step to the 6th
Step, until all interface topologys find success.
Based on above-mentioned design, scheme provided in this embodiment be may not need dependent on the ether interface under standard agreement, be removed
The link of ether interface can be checked, the link of all kinds of interfaces of wide area network can also be detected, it is applicable
Interface is more.In addition, the program can rapid deployment into the net environment for needing to carry out link detecting, the expense of link detecting compared with
Small, the data volume for collecting processing is few, so that the speed of link detecting is fast.
Referring to figure 4., the embodiment of the present application also provides a kind of link detecting device 100.The link detecting device 100 can be with
Applied in above-mentioned server 10, storage mould can be stored in the form of software or firmware (firmware) including at least one
In block 13 or the software function module that is solidificated in 10 operating system of server (operating system, OS).Link inspection
Surveying device 100 can be used for executing each step of chain circuit detecting method, can improve and is only capable of in the prior art to ether interface
The technical issues of link is detected.Wherein, which may include instruction sending unit 110, judging unit
120 and result determination unit 130.
Instruction sending unit 110, for sending the communication connection status for indicating its first interface to the first Devices to test 20
The first instruction of the second state is switched to by first state.
Optionally, instruction sending unit 110 is also used to successively choose the place of the first Devices to test 20 based on interface message table
In first state interface as first interface, send the first instruction to the first Devices to test 20, include first in the first instruction
The identification information of interface.
Judging unit 120, during being switched to the second state by first state for the communication connection status in first interface,
