The structure of the above-mentioned described ADN network systems of the embodiment of the present application is to more clearly illustrate the application reality
The technical solution of example is applied, does not form the restriction for technical solution provided by the embodiments of the present application, ordinary skill people
For member it is found that in the ADN network systems of different structure, technical solution provided by the embodiments of the present application asks similar technology
Topic, it is equally applicable.
The embodiment of the present application provides a kind of network failure probing method, can apply the network structure in similar to Fig. 1
In ADN network systems.This method can find failure in time when the network node in ADN networks breaks down, and promote ADN nets
The O＆M efficiency and service quality of network.As shown in Fig. 2, this method includes the following steps
S101, control centre's equipment obtain the network connection state in ADN networks between each network node.
Specifically, ADN network nodes can continue between detecting each network node, including returning between source node and source station
Network connection situation, and these data are all transferred to control centre's equipment.
S102, abnormal network node in ADN networks is determined according to network connection state.
In one embodiment, step S102 specifically includes the content of following S102a1-S102a2：
S102a1, determine that target network node connects the number of obstructed network node according to network connection state.
If S102a2, the number to the obstructed network node of target network node connection are more than threshold value, target network is determined
Network node is abnormal network node.
In the embodiment of the present application, using the connection status of other network nodes to target network node, target network is determined
The health status of node.When the connection of the network node more than threshold number to target network node is obstructed, then the mesh is judged
Mark the operation exception of network node.
In another embodiment, before step S102 is performed, this method further includes：Obtain at least one network path
Path configuration data, path configuration data includes the network node that a network path is passed through.Step S102 is specifically wrapped
It includes：
S102b, the path configuration data according to network connection state and at least one network path, determine target network section
There is specified upper hop network node o'clock at least one network path, and upper hop network node is to target network node
Connection it is obstructed when, determine target network node be abnormal network node.
Specifically, control centre's equipment preserves the path configuration data of each network service.It is included in the configuration data of path
Have the access node of the corresponding network path of network service, the network address of source station, sometimes can also include transit node and
The network address of source node is returned, and is organized these network nodes in the form of configuration path.It is selected in ADN networks
Lu Shi, can network node information in the configuration data of path, select the optimal paths of process these network nodes.Cause
This, when being determined in the path configuration data from a network path, target network node exists specified in a network path
Upper hop network node when, then when the connection of upper hop network node to the target network node is obstructed, you can with true
The fixed target network node is there are failure, and the transmission services for having network path are affected.And then the embodiment of the present application
In, by obtain at least one network path path configuration data, and using the path configuration data determine this at least one
Whether include target network node and the specified upper hop network with the presence or absence of the target network node in network path
Node so as to whether unimpeded by the connection of upper hop network node to target network node for judging to specify, and then determines mesh
The operating condition that the operating condition of mark network node and at least one network path pass through the target network node.
In addition, in the above-mentioned methods due to the upper hop network node to being connected between the target network node
Few use determines that abnormal network node can be filtered out to real network in a network path, therefore by this method
Service does not have influential Network Abnormal to fluctuate, and more accurately judges to influence the abnormal conditions of the network node of network service.
If for example, the connection of network node A to network node B are obstructed, but network node A is not appeared in any configuration path,
The path configuration data of i.e. no any network path includes network node A, then even if network node A to network node B
Connection it is obstructed, the network service carried in ADN networks can't be affected, thus at this time and without using network node B as
Abnormal nodes.
Illustratively, if including the net of the access node of the network path in the path configuration data of a network path
The network address of network address, the network address for returning source node and source station.So when the connection for going back to source node to source station is obstructed,
It is abnormal nodes then to determine the source station.
S103, the network path for passing through abnormal network node is detected.
In one embodiment, step S103 specifically includes the content of following S103a1-S103a3：
S103a1, judge whether abnormal network node is access node in network path.
S103a2, when determining abnormal network node as the access node in network path, then judge whether at least to exist pre-
If the connection of the network node of number to abnormal network node is obstructed.
If S103a3, judge at least there are the network node of predetermined number to abnormal network node connection it is obstructed when, really
The fixed network path operation exception.
Specifically, it is considered that when the connection more than a certain number of network nodes to access node is obstructed, then exist very
Big probability causes terminal device that network request can not be sent to the access node, and is being to connect using global routing function
Ingress selects that during next-hop network node suitable network node may also can not be selected.And then in the application, when abnormal net
When network node is the access node in network path, the number of the network node by determining the abnormal network node is come true
Whether the fixed network path is affected.
Further, in one embodiment, determine abnormal network node in network path in step S103a2
After access node, this method can also include：Control centre's equipment is sent to global load balancing device stops dispatch command, with
So that global load balancing device stops network request being dispatched to abnormal network node according to dispatch command is stopped.
After the trouble shooting for determining the access node, this method further includes：Control centre's equipment is to global load balancing
Device sends restoration schedule instruction so that global load balancing device restore network request being dispatched to according to restoration schedule instruction it is different
Normal network node.
In the present embodiment, it is contemplated that when the access node in network path is there are when exception or failure, then influence whether
Subsequently it is dispatched to the transmission of other network requests of the access node.Therefore the access node in network path is determined is abnormal
Afterwards, control centre's equipment is then sent to global load balancing device stops dispatch command, so that the stopping of global load balancing device will
Network request is dispatched to abnormal network node.And then avoid causes other follow-up networks please since access node breaks down
The problem of transmission asked is affected.
In another embodiment, step S103 is specifically included：
S103b1, judge whether abnormal network node is access node in network path；
S103b2, when abnormal network node is other network nodes except the access node in network path, then judge
It whether there is the specified upper hop network node of abnormal network node in network path.
If S103b3, in network path there are the specified upper hop network node of abnormal network node, and upper hop
Network node to abnormal network node connection it is obstructed when, determine network path operation exception；If it alternatively, is not deposited in network path
In the specified upper hop network node of abnormal network node, and at least network node of predetermined number is to abnormal network node
Connection it is obstructed when, determine network path operation exception.
Specifically, after the non-access node during network path is determined is abnormal network node, it is different that this can't be provided
Whether the failure of normal network node has influenced the operation of network path.Determining that the abnormal nodes are not accesses in the present embodiment
After node, influence of the abnormal nodes to network path is judged in two kinds of situation：
If there are specified upper the one of the abnormal network node and the abnormal network node in the first situation, network path
Network node is jumped, i.e., that is the abnormal network node and specified upper hop network node are saved in network path
Point, therefore the two nodes can not be bypassed using the global routing function of ADN networks, again path is selected for network path.
At this time if upper hop network node to the abnormal network node connection it is obstructed when, can determine that the network path can be by shadow
It rings.For example, if network node B is abnormal network node, network node A is net in the path configuration data of a network path
The upper hop network node of network node B, then when network node A is obstructed to network node B connections, it may be determined that the network path
It is affected.
If in the second situation, network path there is no the abnormal network node and the abnormal network node it is specified on
One jumps network node, i.e., that is during specifically the data such as network request are sent, global routing function is needed to come for this
Abnormal network node selects suitable upper hop network node.And then in the present embodiment, by determining the abnormal network node
The obstructed network node of connection number, to judge the overall operation situation of the abnormal network node.If there is default at this time
Several network nodes to the abnormal network node connect it is obstructed, then can determine may also be difficult even with global routing function
Suitable upper hop network node is selected for the abnormal network node.As a result, in the present embodiment, when being not present in network path
The specified upper hop network node of abnormal network node, and at least network node of predetermined number is to abnormal network node
When connecting obstructed, it is determined that the network path operation exception.
In one embodiment, the abnormal network node in step S102 determines ADN networks according to network connection state
When, can simultaneously recording exceptional network node abnormal cause.For example, it will be detected using the method for S102a1-S102a2
The abnormal cause of abnormal network node is recorded as " connection more than network node to the present networks node of threshold number is obstructed ", will
The abnormal cause of abnormal network node detected using the method for step S102b be recorded as " in network path with direct phase
Neighbors connection is obstructed ".
And then it when step S103 by the network path of abnormal network node to being detected, then can directly utilize
The abnormal cause of abnormal network node is detected.For example, when determining abnormal network node for the access section in network path
Point is then judging whether at least there are the connection of the network node of the predetermined number abnormal network node not in step S103a2
When logical, the abnormal cause of abnormal network node can be directly inquired, when the abnormal cause for determining the abnormal network node is above-mentioned
" connection more than network node to the present networks node of threshold number is obstructed ", then can directly determine that the network path receives
The influence of abnormal network node, the network path operation exception.For another example when determining that abnormal network node is in network path B
Other network nodes in addition to access node then inquire the abnormal cause of abnormal network node, when abnormal cause is " in network
In the B of path, it is connect with direct neighbor node obstructed ", it is determined that the abnormal network node exists in network path one on specified
The connection jumped between network node and the two adjacent nodes is obstructed, that is, performs and complete the interior of step S103b2-S103b3
Hold.
S104, when detecting network path operation exception, send out warning information.
Specifically, working as the failure detected in abnormal network node has influenced network path operation, i.e. the network road
Diameter operation exception then can send out warning information, to notify that operation maintenance personnel is timely by sending the modes such as alarm email, short message
Solve the problem.
Further, in one embodiment, warning information includes the abnormal network node for influencing network path operation
Location information and abnormal cause.To help the timely failure judgement position of operation maintenance personnel and reason.
In the application, the network connection state in the ADN networks that control centre's equipment utilization obtains between each network node,
Network node in ADN networks is detected.It is achieved thereby that fault-finding is carried out in ADN networks so that when ADN networks
In network node can find failure in time, and then promote the O＆M efficiency and service quality of ADN networks when breaking down.
