Specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.It should be appreciated that described herein be embodied as
Example limits the present invention only to explain the present invention, not.
As shown in figure 1, the embodiment of the present invention provides a kind of network element link finds method, including：
S11, the target network element in command net send preset data to other network elements in the network；
S12, receives the feedback message of other network elements to the preset data；
Whether S13, other network elements according to the feedback message determines are connected with the target network element.
Network element link provided in an embodiment of the present invention finds method, and target network element that can be in command net is to institute
State other network elements in network preset data, and other network elements described in receiving are sent to the anti-of the preset data
Message is presented, then whether other network elements according to the feedback message determines are connected with the target network element.
In this manner it is possible in network management aspect master goal network element and other network elements connection, by right
Network element in network carries out such operation one by one and can just know that the connection in network between all network elements is closed
System, determines network topology structure, so as to effectively strengthen the effective management to network.
Optionally, preset data can include the data mutually arranged between various network elements, embodiments of the invention
This is not limited.Due to generation and detection technique all comparative maturities of the pseudo-random sequence of each network element, in the present invention
One embodiment in, the target network element in step S11 in command net is to other network elements in the network
Sending preset data specifically may include：The target network element is ordered to send pseudo noise code to described other network elements；
Other network elements described in receiving in step s 12 are specifically may include to the feedback message of the preset data：Receive
Check results of described other network elements to the pseudo noise code.For example, the network element that webmaster can be managed to which
In a network element A transmitting order to lower levels, make A send a string of pseudo-random code sequences from oneself e1 port
PRBS, while webmaster transmitting order to lower levels, makes all of the port on other network elements open the diagnostic function of PRBS,
The result that they diagnose can be reported webmaster by the port of these network elements.By the diagnosis of other network elements, can
To determine whether the data for each whether receiving data and receiving are corresponding pseudo noise code, if school
It is corresponding pseudo noise code to test out the data for receiving, then check results are correct, perform the network element of verification operation
Corresponding check results are sent to Network Management Equipment.
After webmaster receives the feedback message of other network elements, in step s 13 can be according to the feedback message
It is determined that whether described other network elements are connected with the target network element.Specifically may include：Determine that check results are correct
Network element be connected with the target network element, the network element of check results mistake is not attached to the target network element.
In order to improve the degree of accuracy of links between network elements relation detection, on the basis of detection pseudo noise code, may be used also
To increase the transmission and detection of other preset datas.For example, in one embodiment of the invention, order institute
Target network element is stated to after described other network elements transmission pseudo noise codes, be may also include：Order the target network element
AIS data are sent to described other network elements；Whether described other network elements according to the feedback message determines
Be connected with the target network element including：Network element that the is check results correct and producing AIS warnings is defined as
It is connected with the target network element, otherwise determines that the network element is not attached to the target network element.Due to AIS numbers
According to particularity, only send intentionally, be typically not in such data in network, therefore, such as
Fruit target network element have sent AIS data, and the data by some of network, other network elements are received, just
Can determine what the network element for receiving AIS data and target network element were connected to.Due to AIS data have it is special
Property, the network element for receiving can produce AIS warnings, and be sent to warning message to Network Management Equipment.In the warning
Unit marks and port numbers are carried in message, so that Network Management Equipment is recognized.
Method is described in detail to be found to the network element link that the present invention is provided below by specific embodiment.Figure
2 is the network distribution schematic diagram of several network elements under Network Management Equipment management.During Fig. 3 is the present embodiment, net
The flow chart of first link discovery method, the method may particularly include following steps：
201st, Network Management Equipment starts and monitors；
202nd, Network Management Equipment transmitting order to lower levels, allowing；
203rd, the A ports of network element 1 send PRBS data to network element 2 and network element 3；
The E1 ends of other network elements (network element 2 and network element 3) under Network Management Equipment transmitting order to lower levels, order management
Mouth is switched on the diagnostic function of PRBS；
204th, the result of the diagnosis of PRBS is all reported net by the e1 port of other network elements such as network element 2,3
Tube apparatus；After Network Management Equipment collects diagnostic result, will diagnosis the bit error rate be 0 port label for it is doubtful with
The port that the A ports of network element 1 are connected；
205th, wait several seconds for, Network Management Equipment says the word and allows the A ports of network element 1 to stop sending PRBS；Net
Tube apparatus say the word allow network element 2,3 stop PRBS diagnosis；Network Management Equipment says the word and allows the A of network element 1
Port sends AIS data；
206th, network element 1 sends AIS data to network element 2,3 by A ports；
207th, the ais alarm of the above-mentioned doubtful port of Network Management Equipment monitoring reports situation；
208th, determine that the port for producing ais alarm is the port being connected with the A ports of network element 1；
209th, alarm is closed, is terminated.
It should be noted that during the link of above-mentioned detection network element 1, in order to improve link discovery
Accuracy, can repeat more than 201 to 209 times.After the link that Network Management Equipment determines network element 1,
Network Management Equipment can order network element 2 B ports as port to be checked, repeat step 201 to 209, so as to
It is determined that the port being connected with the B ports of network element 2, then order network element 3 carries out similar operation, so as to most
The topological structure of whole E1 links is found eventually.
In the present embodiment, the acquisition link information of Network Management Equipment energy intuitive and convenient improves efficiency, while being also
Follow-up fault diagnosis functions end to end provide link foundation.
