Embodiment
Core concept of the present invention is by initiating node generation and each node transmission topological message in frame type equipment, generate topological data by each node in the frame type equipment according to this topological message, and collect the pairing topological data of each node by initiating node, thereby make that initiating node can carry out failure diagnosis according to the pairing topological data of each node, and diagnose out node and the link that breaks down.Thereby realized the automatic diagnosis process of communication between plates fault, do not needed manual intervention.
As shown in Figure 2, a kind of fault Diagnosis Method for the present invention's proposition, be applied to comprise in the frame type equipment of initiating node and terminal node, described initiation node is connected by backboard in described frame type equipment with described terminal node, described initiation node and each terminal node constitute a paths on described backboard, said method comprising the steps of:
For fault Diagnosis Method provided by the present invention more clearly is described, the present invention is given unnecessary details in detail below in conjunction with a kind of concrete application scenarios.
As shown in Figure 3, this method may further comprise the steps:
Step 301 is initiated node and is set up the communication between plates topology.Wherein, in the frame communication equipment, each veneer is that the position of knowing all veneers in the frame communication equipment concerns, promptly initiates the position relation that node is known all veneers, and according to the position relation of all veneers, this initiation node can be set up the communication between plates topology.
Concrete, because being information, the process of communication between plates is delivered to the process of another node from a node, among the present invention,, at first be defined as follows notion for communication between plates Fault Diagnosis process more clearly is described:
(1) initiates node, the i.e. sender of information;
(2) terminal node, the i.e. recipient of information;
(3) relay nodes is promptly at the node of initiating to play between node and the terminal node transfer effect.
Certainly, in actual applications, be not limited to above-mentioned definition mode, this definition mode can be selected arbitrarily according to actual needs, for example, the initiation node can be defined as the recipient of information, terminal node is defined as the sender of information, and at this moment, the main body of setting up the communication between plates topology in the above-mentioned steps 301 will become terminal node, the process of definition mode is similar among processing procedure and the present invention, gives unnecessary details no longer in detail.
For many single board communications equipment shown in Figure 1, because information can be delivered to cable card board from master control borad, promptly among the present invention, master control borad can be chosen as the initiation node, cable card board is chosen as terminal node, is relay nodes with the choice of equipment between master control borad and the cable card board; Wherein, in communication equipment, the equipment between master control borad and cable card board is inner exchanging net or chip etc., and promptly the relay nodes among the present invention is above-mentioned inner exchanging net, perhaps equipment such as chip.
Because being the position of knowing equipment such as each cable card board and inner exchanging net, master control borad concerns, promptly this master control borad can directly be set up the communication between plates topology, the communication between plates topology of many single board communications equipment as shown in Figure 4, be communication between plates topology, can be expressed as one tree shape model corresponding to many single board communications equipment shown in Figure 1.
In Fig. 4, the tree root node is for initiating node (master control borad), and the subtree of this initiation node is constituted by initiating each paths of node towards each terminal node (cable card board).Among the present invention, need be numbered every paths, the mode of this numbering can be selected arbitrarily, for example, from left to right number consecutively be 1,2 ... etc.; Perhaps, from right to left number consecutively be 1,2 ... etc.As can be seen, the numbering of every paths and the numbering of subtree are corresponding, and promptly when number consecutively was 1,2,3 from right to left in the path, then subtree was followed successively by 1,2,3 from right to left according to numbering.
Further, in Fig. 4, the solid line of band arrow is the link of link node, and a side at arrow place is the end of link, and the other end then is the top of link.Wherein, at the node of both link ends,, at this moment, the top node of link can be called forerunner's node of end node with constituting forerunner and follow-up relation; Corresponding, also the end node of link can be called the successor node of top node.Need to prove, be positioned at relay nodes on the same paths and also can exist a plurality ofly, and also will constitute the relation of forerunner's node and successor node between a plurality of relay nodes.
In addition, between the node of same level, constitute brotherhood, i.e. sibling each other between the node of same level, for example, sibling each other between the relay nodes among Fig. 4, also sibling each other between the terminal node.
Need to prove, in the frame communication equipment, can have the polylith master control borad, every master control borad can be set up the communication between plates topology then as initiating node, promptly safeguards communication between plates topology shown in Figure 4.
Step 302 is initiated node and is generated topological message.Wherein, all veneers in the frame communication equipment all need to discern and to add up this topological message, and promptly all nodes in the communication between plates topology all need to discern and to add up this topological message.On all nodes can both base of recognition, the form of this topological message can be provided with arbitrarily according to actual needs, this topological message is not carried out any restriction among the present invention.
Step 303 is initiated node and is sent topological message according to preset period to terminal node.Wherein, this preset period can be selected arbitrarily according to actual needs.
Concrete, initiate node and can send topological message to all terminal nodes, for example, initiate node from left to right successively the terminal node on every paths send topological message; Perhaps, initiate node from right to left successively the terminal node on every paths send topological message; Certainly, the process of this transmission topological message is not limited to aforesaid way, can select different paths to send topological message arbitrarily, only need guarantee that the path of all terminal node correspondences in same preset period all is covered to, each terminal node also all is covered to and gets final product.Wherein, this initiation node can select a pairing path of terminal node to send at every turn, perhaps, selects the pairing path of a plurality of terminal nodes to send simultaneously, perhaps, selects the pairing path of all terminal nodes to send simultaneously.
Certainly, in actual applications, this initiates node can also send topological message to the part terminal node, for example, when path 2 and path 3 possibility of communication between plates faults takes place when very high, then initiating node can be only to path 2 pairing terminal node, and path 3 pairing terminal nodes send topological message, gives unnecessary details no longer in detail among the present invention.
Concrete, all nodes in the communication between plates topology are called the topological data of this node at the statistics of this topological message, wherein, initiate the topological data that node has only transmission, terminal node has only the topological data of reception, and relay nodes has the topological data of transmission and the topological data of reception.
Illustrate that with a concrete example node adds up and generate the process of topological data to topological message below:
For the initiation node, topological message of every transmission, then the numerical value with topological data adds 1, and for example, when the initiation node sent topological message for the first time, then topological data was 1; When the initiation node had sent 10 topological message altogether, then topological data was 10.Certainly, in actual applications, initiate topological data in the node and be to need and concrete path one to one, for example, for path 1, when the initiation node had sent 10 topological message altogether, then the topological data in path 1 was 10; And for path 2, when the initiation node had sent 8 topological message altogether, then the topological data in path 2 was 8.
Same, for terminal node, topological message of every reception, then the numerical value with topological data adds 1, and for example, when terminal node had received 10 topological message altogether, then topological data was 10.
For relay nodes, topological message of every reception, the numerical value that then will receive pairing topological data adds 1, and topological message of every transmission, the numerical value that then will send pairing topological data adds 1.
Need to prove; should be not limited to aforesaid way by the mode of topological message generation topological data; can select arbitrarily in actual applications, all can be by adding up and generated topological data to topological message mode is all within protection range of the present invention.For example, can topological message be converted to topological data according to default function; Again for example, can topological message of every reception, then the numerical value of topological data is added 2 etc., give unnecessary details no longer in detail among the present invention.
Step 305 is initiated node and is collected topological data, and carries out failure diagnosis according to this topological data.Wherein, this initiates node can collect the pairing topological data of each node on the path self be concerned about or all paths according to the needs of self, for example, initiates node and regularly travels through the subtree of self, promptly travel through every paths, obtain the topological data of each node on the path; When traverse path, the topological data of the node of access modes collection successively will be taked from top to bottom.
The process of carrying out failure diagnosis according to topological data specifically comprises:
(1) send the topological message failure if initiate node, then explanation initiation node breaks down.
(2) if initiate the topological data failure that node obtains certain node (for example, node 1), fault has taken place in the link that forerunner's node that this node (node 1) or this node correspondence then be described leads to this node.
(3) after the initiation node obtains the topological data success of certain node, this initiation node will carry out the comparison of topological data.
If the reception topological data of this node, then illustrates the link that forerunner's node of this node or this node correspondence leads to this node less than the transmission topological data of forerunner's node of this node correspondence fault has taken place.If the transmission topological data of forerunner's node that the reception topological data of this node and this node are corresponding is identical, the link that forerunner's node that this node and this node correspondence then be described leads to this node does not break down.
For relay nodes, initiate node when carrying out the comparison of topological data, also need relatively pairing reception topological data of this relay nodes and transmission topological data,, illustrate that then the transmission fault has appearred in this relay nodes if receive topological data greater than sending topological data.
For said process more clearly is described, with communication between plates topological structure shown in Figure 4 is that example is elaborated, and the pairing topological data of each node is an example in the node collection path 1 (being the path of cable card board 1 correspondence) to initiate in this step, has only a relay nodes in the path 1, at this moment, this initiation node need be collected the topological data of self, the topological data of relay nodes (relay nodes of respective path 1), the topological data of terminal node (cable card board 1).
Concrete, with every transmission or receive topological message one time, the numerical value of topological data is added 1 be example among the present invention, illustrate that this carries out the process of failure diagnosis according to topological data, comprising:
(1) send the topological message failure if initiate node, the topological data of promptly initiating node self is 0 o'clock, and then explanation initiation node breaks down.
(2) send the topological message success if initiate node, but can't get access to the topological data of relay nodes, illustrate that then relay nodes and/or the link of initiating between node and the relay nodes break down.
(3), initiate topological data (data 1) and the corresponding topological data (data 2) of relay nodes reception that node will compare self if initiate the topological data that node gets access to relay nodes.When data 1 during, illustrate that then relay nodes and/or the link of initiating between node and the relay nodes break down greater than data 2; When data 1 and data 2 were identical, then the explanation link of initiating between node and the relay nodes did not break down.
In addition, this initiation node also needs the comparison relay nodes to receive corresponding topological data and relay nodes sends corresponding topological data (data 3).When data 2 during, illustrate that then relay nodes breaks down greater than data 3; When data 2 and data 3 are identical, illustrate that then relay nodes does not break down.
(4), initiate node and will compare topological data and the corresponding topological data (data 4) of terminal node reception that relay nodes sends correspondence if initiate the topological data that node gets access to terminal node.When data 3 during, illustrate that then the link between terminal node and/or relay nodes and the terminal node breaks down greater than data 4; When data 3 and data 4 are identical, illustrate that then the link between relay nodes and the terminal node does not break down.
Need to prove, above-mentioned process of carrying out failure diagnosis is the signal situation at diagnostic procedure on the path 1 in the communication between plates topological structure shown in Figure 4, in actual applications, relay nodes on one paths may have a plurality of, the processing procedure of the processing procedure of each relay nodes and relay nodes shown in Figure 4 is similar, gives unnecessary details no longer in detail at this.
Certainly, in the application of reality, initiate node and carry out failure diagnosis, and locate after the out of order place, can also comprise:
Step 306 takes the recovery means to attempt fixing a breakdown.
Wherein, the step among the present invention can also be adjusted according to the actual needs.
Below in conjunction with another kind of application scenarios method for diagnosing faults proposed by the invention is described, same at many single board communications equipment shown in Figure 1, under application scenarios shown in Figure 4, master control borad is a communication between plates topology of setting up tree shaped model; And should be with under the scene, the communication between plates topology of setting up Two Binomial Tree Model shown in Figure 5 with master control borad is an example.
Should be with under the scene, in this communication between plates topology, initiating node (master control borad) is the tree root node, the left subtree of each node is made of the successor node of oneself, and the right subtree of this node is made of oneself sibling.
Concrete, the left subtree of tree root node (initiation node), and be each subtree of root node with tree root node left side child's (relay nodes 1) sibling (relay nodes 2... via node n), constituted by initiating each paths of node towards each terminal node, the numbering in path is corresponding one by one with the numbering of above-mentioned subtree.Wherein, the left subtree of tree root node be relay nodes 1 to cable card board 1, tree root node left side child's sibling be the subtree of root node be respectively relay nodes 2 to cable card board 2... relay nodes n to cable card board n.
Should be with under the scene, after above-mentioned communication between plates topology is set up and is finished, this initiates node will send the topological message that self generates according to preset period and this communication between plates topology to terminal node, in the process of transmitting of this topological message, this topological message will be through each node in the subtree, for example, will be in the topological message of issuing cable card board 1 through relay nodes 1, and receiving track clamp 1; Will be in the topological message of issuing cable card board 2 through relay nodes 2, and receiving track clamp 2.
In the subsequent process, each node in the communication between plates topology will generate topological data according to this topological message, and by initiating the topological data that node is collected each node, carry out failure diagnosis then.Need to prove, communication between plates topology set up finish after, in the subsequent process with step 302-step 306 in processing procedure similar, should repeat no more with under the scene.
Below in conjunction with another kind of application scenarios method for diagnosing faults proposed by the invention is described again, same at many single board communications equipment shown in Figure 1, under application scenarios shown in Figure 4, be that the initiation node is that example describes with the master control borad; And should be with under the scene, be example with cable card board as initiating node, communication between plates topology as shown in Figure 6; As can be seen, at application scenarios shown in Figure 5, can repeat no more among the present invention by cable card board as initiating node too.
Should be with under the scene, generate topological message by cable card board (initiation node), and send topological message to master control borad according to preset period, as can be seen, each cable card board (cable card board 1, cable card board 2 etc.) all needs to send topological message to master control borad, then failure diagnosis is carried out in self pairing path, owing to should be to initiate node with this cable card board under the scene, master control borad is a terminal node, processing procedure in processing procedure and the step 302-step 306 is similar, should be with giving unnecessary details no longer in detail under the scene.
