In prior art, the embodiment for the problems referred to above has the disadvantage in that
1) location of link failure is only limited in when transmission link interrupts and performs by prior art, and the link-quality degradation phenomena occurred in the short time cannot be monitored location.Such as, when network link occurs that link-quality deteriorates, and when recovering in very short time; existing monitoring method would generally think that Link State is normal; but, the business of link carrying can be had a huge impact by the link-quality deterioration of moment, reduces the quality of business；
2) shortage judges, based on the whole network, the means that link-quality deteriorates.The embodiment of prior art can only position port status according to phenomenon of the failure, and the link-quality (e.g., packet loss, re-transmission etc.) for whole network cannot be added up.Such as; if some link is because of reasons such as external cause, rate-matched or loop networks; often occur that port status is normal; but in this case; there may be link and cannot carry the phenomenon of quality of service extreme difference after business or link bearer traffic, this problem is difficult to location concrete reason based on prior art；
3) fault linkage location difficulty.For monitoring personnel, network details in core bearer network cannot be recognized in detail, and network monitoring personnel often monitor many cover systems simultaneously, workload is huge, therefore, is not easy timely discovery when business goes wrong, and cannot accurately and timely get network details at that time, when the relevant alarm of link-quality especially occurs, fault location difficulty, it is impossible to investigate fault fast and accurately；
4) visual monitoring ability lacks.In prior art, only by configuration Simple Network Management Protocol (SimpleNetworkManagementProtocol, SNMP), according to the SNMP datacom device warning information reported, log in after target device checks analysis, could fault point.But for catenet, network node is many, and link is more complicated, existing embodiment is difficult to intuitively present the link of full mesh topology formula and represents.
In sum, in prior art, to network link monitoring means major part, simply whether monitoring link is unimpeded, the degradation phenomena that, moment random for link transmission quality occurs is difficult to timely seizure, and quality deterioration phenomenon can not be reflected in real time intuitively, cause the location information that can not collect fault in time, traffic affecting quality.

Detailed description of the invention
In the embodiment of the present invention, after occurring that one or more link that packet loss changes is weighted accumulation algorithm by time poll statistics far-end measuring point, the node that statistics packet loss weight is the highest, position link failure node, and visualize in monitoring system and to present, comprehensively represent total network links quality.
Referring next to accompanying drawing, the preferred scheme of the embodiment of the present invention is described in detail.
The embodiment of the present invention is introduced for the application of data link layer, as shown in Figure 1, numerous for node, by the network of the two-layer of convergence switch and core router composition or three-decker.
At pretreatment stage, configure measuring parameter.Specifically, physical layer network link network element, data link layer and Internet datacom device are carried out far-end measuring parametric statistics configuration, for instance, configuration statistics node, network quality, packet loss counter parameter, SNMP server address etc..Further, the fundamental packets quality information on statistics interface communication channels.
After for server, the interface IP address to network element and datacom device is set, each network element node data information and network link quality information in collection of server bearer network, specifically, facility information is passed to server by the nodal information that network element and datacom device measure statistical items by far-end measuring point (i.e. Remotesite) and snmp protocol reports.
Consulting shown in Fig. 2, in the embodiment of the present invention, in carrying out network link quality monitoring process, server specifically performs following operation:
Step 200: each equipment running status information in monitoring system, and the channel quality relevant parameter of each equipment is added up, the link meeting the equipment of preset failure condition through channel quality relevant parameter is judged to faulty link each node of record trouble link process.
The channel quality relevant parameter of each equipment in system is added up by server, and wherein, channel quality relevant parameter includes packet loss, time delay, shake etc., and the embodiment of the present invention adopts packet loss to judge the channel quality of each equipment.Concrete judgment mode can adopt but be not limited to time polling mode, and detailed process is:
1) according to the time observed value preset and the packet loss number of times thresholding of presetting, each equipment is carried out packet loss statistics, whenever determining equipment packet loss number of times in default time observed value higher than described packet loss number of times thresholding, the packet loss number information of record one equipment, wherein, time observed value is for indicating the interval carrying out packet loss statistics.
Such as, Preset Time observed value is 5 minutes, and presetting packet loss number of times thresholding is 400 times, it is, triggered statistics to each equipment every 5 minutes, however, it is determined that equipment packet loss number of times interior at 5 minutes higher than 400 times, then records the packet loss number information of this equipment；If it is determined that equipment at every 5 minutes interior packet loss number of times not higher than 400 times, then do not record the packet loss number information of this equipment, namely abandon the packet loss number information of this equipment.After statistics, enumerator is zeroed out, in order to statistics next time.
2) for each equipment of record packet loss number information, adopt the tracking mode preset, each the link through this each equipment is faulty link each node of record trouble link process.
In step 1) in obtain record result in, the channel quality relevant parameter of each equipment meets preset failure condition, namely the packet loss number of times of each equipment is higher than the packet loss number of times thresholding preset in Preset Time observed value, therefore, each equipment is recorded as faulty equipment.
For each faulty equipment, adopt the tracking mode preset, each the link through this each equipment is all judged to faulty link.Certainly, the channel quality relevant parameter that the judgement of faulty link is according to link-quality rule and far-end measuring point and equipment together decides on, and measures in order to convenient, each the link through this each faulty equipment is all judged to faulty link.
The tracking mode preset can be, but not limited to adopt follows the tracks of the mode that route (i.e. Traceroute) is corresponding with IP address, and wherein, Traceroute is a kind of network technology, the router of displayable data bag process or the IP address of switch.
First, after utilizing Traceroute instrument to obtain the IP address of each node, the corresponding relation editing network topology according to IP address with nodename, the link end to end of each equipment room in configuration network.
Then, by each faulty equipment, sending path trace, record all paths through faulty equipment, each paths is a faulty link.
Then, add up each node of each faulty link process and be recorded.
Step 210: calculate the fault right weight of each node of each faulty link process respectively, this fault right weight is for indicating node credibility as failure cause in all faulty links.
Specifically, for each faulty link, it is determined that the fault right weight of each node of faulty link process, concrete calculating process is as follows:
1, each node is traveled through, an often selected node, statistics is through all faulty links of this node, based on the interstitial content comprised in each faulty link of this node, calculate the ratio that this node is shared in the node total number order of the faulty link of each this node of process respectively.
When multiple equipment of same time breaks down and alerts, multilink can be caused to break down simultaneously, server determines, by the tracking mode preset, the link paths broken down, assume after server analysis, confirm related three link failure of same time, Article 1, faulty link is altogether through 4 nodes, Article 2 faulty link is altogether through 5 nodes, Article 3 faulty link is altogether through 6 nodes, but, these three faulty links may comprise the node of common process, therefore, the all nodes comprised in three faulty links are traveled through by server, often during a selected node, judge the number ratio that this node is shared in the faulty link of each this node of process.
Such as, a selected node (being designated as node 1), if above-mentioned 3 faulty links both pass through this node, due to Article 1 faulty link altogether through 4 nodes, Article 2 faulty link is altogether through 5 nodes, and Article 3 faulty link is altogether through 6 nodes, therefore, the node 1 ratio shared by Article 1 faulty link is 1/4, and ratio shared in Article 2 faulty link is 1/5, and ratio shared in Article 3 link is 1/6；
Again such as, selected node 2, if above-mentioned Article 2 faulty link and Article 3 faulty link both pass through this node, the ratio that then node 2 is shared in Article 2 faulty link is 1/5, ratio shared in Article 3 link is 1/6, owing to Article 1 faulty link is without node 2, so the ratio that node 2 is shared by Article 1 faulty link is 0；
The number ratio that in these three faulty links, all nodes are shared in its faulty link of each process is determined by same method.
2, by each ratio of obtaining respectively in connection with the cumulative coefficient of this node, obtain this node fraction weight in respective links, the all fractions obtained heavily are added up, obtain accumulation result, this accumulation result is fault right weight, and this cumulative coefficient is for characterizing this node significance level in all links.
Fault right weight W represents, cumulative coefficient X represents, wherein the specific formula for calculation of the fault right weight of any one node is:
In formula [1], NaThe total number of the node for comprising in a link of this node；NbThe total number of the node for comprising in the b link of this node；...；Nn is the total number comprising node in the n link of this node, and X is the cumulative coefficient of this node.
Wherein, this node that cumulative coefficient is calculated out according to the importance of selected node place network topology significance level in all links, for instance, the cumulative coefficient of Access Layer node is 1.2；The cumulative coefficient of convergence-level node is 1.4；The cumulative coefficient of backbone layer node is 1.6.These results are all the measuring and calculating value rule of thumb obtained, and the cumulative coefficient in the embodiment of the present invention is not limited thereto.
Such as, selected in step 1 node 1 location is convergence-level, then the cumulative coefficient of this node is 1.4, calculate, the node 1 fraction weight in these three links, three fractions obtained heavily are added up, obtaining accumulation result, the fault right weight being node 1 (can be designated as W1), then:
So, the fault right weight of node 1 is about 86.3%.
Wherein,For the node 1 fraction weight in Article 1 link, For the node 1 fraction weight in Article 2 link,For the node 1 fraction weight in Article 3 link.
Again such as, node 2 location selected in step 1 is Access Layer, so the cumulative coefficient of node 2 is 1.2, the computing node 1 fraction weight in the Article 2 link passing through it and Article 3 link, two fractions obtained heavily are added up, obtaining accumulation result, the fault right weight being node 2 (can be designated as W2), then:
So, the fault right weight of node 2 is 44%.
Wherein,For the node 2 fraction weight in Article 2 link,For the node 2 fraction weight in Article 3 link.
According to said method, calculate the fault right weight of each node in each faulty link, statistical computation result.
Step 220: choose the highest node of fault right weight and carry out fault location.
Specifically, the fault right weight of each node in each the faulty link obtained in step 210 is compared, chooses the node that fault right weight is the highest, it is determined that the node that this fault right weight is the highest is trouble point.
So far the process of fault location is introduced complete.
It addition, in the process of above-mentioned fault location, obtain network topology by bearer network resource database, the visualization of total network links topological structure is presented.
Specifically, when the device channel quality association parameter of collection of server meets preset failure condition, close with monitoring network duct ligation, in the network topology in monitoring region, present alarm.Faulty link is visualized in network topology and presents, in such manner, it is possible in time the phenomenon of the failure that the moment of total network links quality occurs at random is realized visual check.
Fault location result is presented in total network links topological structure.
After server carries out fault location, final fault location result is presented in the network topology in monitoring region, in such manner, it is possible to point out trouble point to monitoring personnel in time, significantly alleviates the maintenance work of network maintenance staff.
After fault location, fault relevant information is presented in described total network links topological structure.Specifically, according to default fault experience database, fault behind location is associated with this fault experience database, analyze fault relevant information, the fault relevant information of acquisition being presented in full mesh topology topology view, this fault relevant information at least includes Trouble cause, fault causes consequence and troubleshooting are advised.
Wherein, server can obtain alarm relevant information from fault warning experience storehouse, trouble point according to location, alarm title is indexed in fault warning experience storehouse inquiry, the consequence and the troubleshootings suggestion that cause Trouble cause, fault are associated, and the related information of acquisition is carried out visualization in full mesh topology structure chart presents by monitoring network, monitoring attendant is reminded by audible and visual alarm, or, submitting the related information obtained to mail server, mail server passes through mail or/and short message mode notice monitors attendant.
