Embodiment
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail, so that those skilled in the art can better understand the present invention also, can be implemented, but illustrated embodiment is not as a limitation of the invention.It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.
Packet Transport Network of the present invention (PTN) method for diagnosing faults embodiment, as shown in Figure 1, the method comprises:
Step 101: the information of obtaining forward-path and the link nodes equipment of certain PTN tunnel or access service;
In PTN network, no matter there are how many node devices in PTN tunnel, or in PTN network, adopted which agreement, at a time, for a certain access service, the PTN tunnel that it is associated in this network, and the forward-path in this tunnel, be all unique definite and fixing.
Understandably, a PTN tunnel can associated a plurality of access service of while.
Step 102: ruuning situation information and the forwarding information of collecting each link nodes equipment;
Step 103: carry out failure diagnosis according to described ruuning situation information and forwarding information.
Usually, if in the correct situation of device hardware and forwarding information, the business of the PTN network carrying should be normal.
Just how according to ruuning situation information, to carry out failure diagnosis below, and how according to forwarding information, carry out failure diagnosis and provide example explanation, understandably, the mode of specific implementation failure diagnosis is not limited to the following flow process providing.
Alternatively, as shown in Figure 2, according to health information, carry out failure diagnosis and comprise:
Step 201: resolve described ruuning situation information;
Step 202: judge according to the ruuning situation information of resolving whether hardware breaks down;
Step 203: report barrier when judgement hardware breaks down.
Particularly, for different equipment, the information of its concrete analysis and to be judged as the condition of fault different, the present invention does not do any restriction to this.
Alternatively, as shown in Figure 3, according to described forwarding information, carry out failure diagnosis and comprise:
Step 301: the forwarding information of resolving described each link nodes equipment;
Step 302: judge that according to the forwarding information of resolving whether forwarding information is wrong;
Step 303: report barrier when judgement forwarding information is wrong.
Particularly, for different equipment, it judges that the wrong condition of forwarding information is different, and the present invention does not do any restriction to this.
Alternatively, as shown in Figure 4, according to described forwarding information, carry out failure diagnosis and comprise:
Step 401: the forwarding information of resolving described each link nodes equipment;
Step 402: whether the output information that judges the forwarding-table item of upstream link node device mates with the input message of downstream links node device forwarding-table item;
Step 403: report barrier when judgement upstream and downstream link nodes device forwards list item does not mate.
The present invention does not clearly limit carrying out the main body of above-mentioned each process step, it can be realized by certain link nodes equipment, also can be realized by the Special Equipment except link nodes equipment, or realized by the cooperation of a plurality of link nodes equipment, or control a plurality of link nodes equipment respectively or cooperation realizes certain or certain several operations by certain Special Equipment.For concrete implementation, the present invention is not construed as limiting.
Application example
Below in conjunction with accompanying drawing, to realizing PTN network fault diagnosis application example, be specifically described.
In conjunction with Fig. 5, realize PTN network fault diagnosis and specifically carry out following steps:
Step 501: determine the object that needs diagnosis, if access service performs step 502, if PTN tunnel performs step 503;
Determine that needing the PTN access service of diagnosis is access service 1, or some PTN tunnel, tunnel ID is ID1.This is the entrance index of PTN network fault diagnosis.If needs diagnosis is a certain access service, continue to do the operation of step 502, if needs diagnosis is a certain PTN tunnel, continue to do the operation of step 503.
Step 502: according to the access service 1 in step 1, from access head node PE1, obtain the PTN tunnel ID1 that this access service is corresponding.
Step 503: according to tunnel ID1, obtain this tunnel forward-path and the node device information of process;
According to the difference of PTN network application, there is dividing of static tunnel and dynamic tunnel in tunnel.For static tunnel, the forward-path in this PTN tunnel is human configuration, is changeless, be easy to according to PTN tunnel ID obtain its forward-path and the node device of process.For dynamic tunnel, forward-path and the route in this PTN tunnel are closely related, by can determine the forward-path in this tunnel and the node device of its process to the management of whole network topology.
In this application example, this tunnel is through head node equipment PE1, intermediary device P1, P2, tail node equipment PE2.
Step 504: the hardware running state information of collector node equipment PE1, P1, P2, PE2, analyze these information, judge whether it is that hardware goes wrong, if find that the hardware operation of a certain equipment has problem, report barrier, advises preferential this hardware problem that solves, and finishes this failure diagnosis work, if do not find hardware operation problem, continue to do the diagnostic work of step 505;
The hardware running state information of each node device can be obtained from this locality of each node device, here said hardware information is generally more crucial hardware information, particularly, may be different for its key hardware information of different node devices, the present invention is not restricted for concrete hardware information.
Step 505: the forwarding information relevant with this PTN tunnel to this access service of collector node equipment PE1, P1, P2, PE2, analyze the forwarding information of each node device, if noted abnormalities or mistake, report hinders, suggestion solves this mistake, finish this failure diagnosis work, if do not had, continue to do the diagnostic work of step 5;
Step 506: the forwarding information of node device PE1, P1, P2, PE2 described in comparison step 505, whether output, the input forwarding information of analyzing upstream and downstream node device mate, and if do not mated, report barrier, advises solving these mistakes.
According on forward-path, the order of each node device is the forwarding information of each node device relatively, analyzes wherein unmatched mistake, and suggestion solves these mistakes.For some access service and PTN tunnel, the output that the forwarding-table item of upstream node equipment characterizes is the input of downstream node equipment list item, so the forwarding-table item information of two node devices in front and back needs coupling, just can assured forwarding normally carry out.
For realizing said method embodiment and application example, the present invention also provides a kind of Packet Transport Network (PTN) fault diagnosis system embodiment, and as shown in Figure 6, this system comprises:
