Description
Technical field
The present invention relates to the communications field, in particular to a kind of link failure processing method and device.
Background technology
ASON (ASON, Automatic Switched Optical Network) is a kind of new technique that development is come out on the basis of traditional optical transfer network.The ASON network is under the condition that does not need behavior adjustment management and control, and the optical channel that meets user's request is set up in the running of protocol such as a series of routes that can dispose according to self, signaling, automatic discovery by user's request.The research emphasis of ASON is professional transmission, and exchange is controlled and three parts of network management automatically, and respectively by transmitting plane Transport Plane, control plane Control Plane, management plane Management Plane carry out function to be realized.
ASON protect networks and the ability of recovering to require when network breaks down, still can continue normal operation.Protection mechanism can be divided into two types, based on the protection that transmits the plane with based on the protection of control plane.Based on the protection aspect that transmits the plane, ASON supports the network protection mode of SDH (SDH, Synchronous Digital Hierarchy), like Multiplex Section Shared Protection Ring (MS-SPRing mainly contains the guard ring of two fine and four fine two kinds of forms); Protection aspect based on control plane; ASON supports end-to-end (passage) protection; Promptly the whole piece from the source node to the destination node connects protection, when having fault in certain bar connection of bearer service, and the fault detect of professional ability trigger port; Make professional can the recovery, the mode that can also take to preset route simultaneously improves the speed of recovery.
Actual transmission net takes place through regular meeting that some are uncertain unusual when transport service, like the power down of transmission node network element; It is disconnected to connect optical fiber; Professional tabula rasa fault, the cross board fault, it is not enough to build professional SDH time interval resource; There is alarm (external disturbance or inner the generation) in the interface channel of bearer service, and all can exert an influence to service creation and normal operation this moment.In order not influence business, the method that ASON takes is to carry out fault detect to connecting the alarm that produces, and based on the layer that connects not, can be divided into link layer fault detect and channel layer fault detect.
The link layer fault detect need combine to exist actual link condition to carry out in route and the current network of connection itself; In concrete realization, tend to the link condition in the network is divided into two kinds, a kind of is ring protection link (two fiber complex section protection rings or four fiber complex section protection rings); Another kind of common link (comprises unprotected link; 1+1 multiplex section protection link, 1: 1 multiplex section protection link and 1: N multiplex section protection link), judge that connecting the standard that whether breaks down is exactly whether the hop-by-hop route that connects is in ring or common link failure; If exist failure conditions to exist, recover with regard to the triggering business.
The channel layer fault detect is often with " LMP Link Manager Protocol " (LMP, Links Management Protocol) conduct basis, when concrete the realization; Often carry out to single direction; If two-way services then need all be carried out the passage detection in path P ATH direction and reverse RESV direction both direction, the PAHT direction is initiated to detect by the source network element; The RESV direction is initiated to detect by the purpose network element; When a certain section passage had fault in detecting connection, the network element that breaks down can send positioning result to source network element node, and all business recoveries or answer operation are controlled by source network element node.The PATH direction is meant that in the process of connecting first node is initiated the direction of signaling to tail node, otherwise is the RESV direction.
At present; The priority of link layer fault detect is higher than the priority that channel failure detects; Therefore, normal conditions can not start passage and detect, but in link layer fault and the simultaneous situation of channel failure; Possibly only need except wherein a kind of fault rather than all elimination, and then cause the follow-up business mistake to be replied.

Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Mention in the correlation technique; At present, the priority of link layer fault detect is higher than the priority that channel failure detects, therefore; Normal conditions can not start passage and detect; But in link layer fault and the simultaneous situation of channel failure, possibly only need, and then cause the follow-up business mistake to be replied except wherein a kind of fault rather than all elimination.For solving the problems of the technologies described above, the embodiment of the invention provides a kind of link failure processing method, and handling process is as shown in Figure 1, comprising:
In embodiments of the present invention; When on network link connects, having link layer fault and channel failure simultaneously, confirm the order that link layer fault and channel failure take place, and start link layer fault detect and/or channel failure detection according to the order of confirming; In link layer fault and the simultaneous situation of channel failure; Can confirm the fault elimination, avoid the follow-up business mistake to reply, can effectively shorten the cost of research and development time and reduction engineering construction.
During enforcement, flow process as shown in Figure 1, step 104 is when implementing; Start link layer detection and/or channel failure detection according to order, comprise two kinds of situation, a kind of is to occur the link layer fault earlier on link connects; Channel failure appears then; A kind of in addition situation is to occur channel failure earlier on link connects, and occurs the link layer fault then, analyzes respectively at present.
On link connects, occur the link layer fault earlier, when channel failure occurring then, start the link layer fault detect, the link layer fault is repaired; When the link layer fault was repaired, reporting links connected the link layer fault and disappears.
During enforcement, when link connect to be gone up loaded service and had the attribute of recovery, recover professional; And, repaired and business when having reply-attribute when the link layer fault, utilize timer T1 to start channel failure and detect, if channel failure is repaired; Reporting links interface channel fault disappears, and informing business is replied, wherein; The time of timer T1 can be set to random time, decides as the case may be, for example; Can be set to 0, also can be provided with 5 seconds, or the like.
In embodiments of the present invention; If the link layer fault has started the channel failure detection after disappearing, and after the channel failure disappearance; Can connect professional fault disappearance by reporting links; If have only the disappearance of link layer fault or have only channel failure to disappear, only be to eliminate link layer fault or channel failure, can not the reporting service fault disappear.
In another kind of situation, channel failure appears earlier on link connects, and when occurring the link layer fault then, the sign link is connected to: promptly have channel failure, have the link layer fault again; Start the link layer fault detect link layer fault is repaired, and/or, start the channel failure detection channel failure is repaired; Reporting links connects link layer fault and/or channel failure disappearance according to repairing as a result.
During enforcement, link connects and to occur after the channel failure, when link connects when going up loaded service and having the attribute of recovery, recovers professional; And, repaired and business when having reply-attribute when the link layer fault, utilize timer T2 to start channel failure and detect, if channel failure is repaired; Reporting links interface channel fault disappears, and informing business is replied, wherein; The time of timer T2 can be set to random time, decides as the case may be, for example; Can be set to 0, also can be provided with 5 seconds, or the like.The timer T2 here only is used for distinguishing with the timer T1 of preceding text, during description, also can distinguish with first timer, second timer or timer A, timer B.Repaired and business when having reply-attribute when channel failure, informing business is replied.
In embodiments of the present invention; If the link layer fault has started the channel failure detection after disappearing, and after the channel failure disappearance; Can connect professional fault disappearance by reporting links; If have only the disappearance of link layer fault or have only channel failure to disappear, only be to eliminate link layer fault or channel failure, can not the reporting service fault disappear.
The embodiment of the invention provide a kind of in the ASON network when connecting when having link layer fault and channel failure simultaneously, connect the method for carrying out the Coordination Treatment fault, scene process is machine-processed as follows:
(explain: in order to express easily following, the PATH direction that has all connected is an example, in addition; Also need need point out, have alarm not necessarily can produce fault, have only after confirming that through fault detection mechanism the alarm that produces can cause fault " fault " and " alarm " two notions; Could confirm to be connected with fault; As when alarming disturbance outside the alarm section of being,, not necessarily can think to produce to connect fault for testing mechanism.)
One, first link layer fault, back channel failure.
Receive the link layer fault earlier when connecting, when receiving channel failure again then, the link layer fault detect of high priority can suppress channel failure usually and detect, and when promptly occurring the link layer fault in the ban, can not start channel failure and detect.
When having detected the link layer fault, if business has the recovery attribute, this moment, business should be recovered.
When handling failure disappeared, the link layer fault can only disappear through the link layer fault and remove, and channel failure also can only disappear through channel failure and remove, and only receives that these two kinds of faults disappear, and could represent that traffic failure disappears.
When only receiving that the link layer fault disappears, owing to there is not trigger port to detect, channel failure possibly still exist; For the business that reply-attribute is arranged; May cause mistake to reply, in concrete implementation procedure, can use timer T1; Behind timer expiry, carry out the channel failure detection again and decide channel failure whether to exist.
Two, first channel failure, back link layer fault.
Receive channel failure earlier when connecting, receive the link layer fault then again, connection needs clearly to indicate " promptly have channel failure, have the link layer fault again ".If business has the recovery attribute, this moment, business should be recovered.
If only received that the link layer fault that connects disappears or channel failure disappears this moment, connection can not report fault to disappear, and only removes local link corresponding layer malfunction or channel failure state.
If the follow-up channel failure of this connection of having received again disappears or the disappearance of link layer fault, connection need report channel failure to disappear or the link layer fault disappears.
Business receives that the fault of connection disappears, and divides two kinds of situation to handle: disappear for channel failure, if business has reply-attribute, then need not start the answer waiting timer, directly answer gets final product; Disappear for the link layer fault,, need to start and reply waiting timer T2, after timer T2 is overtime,, then reply operation if do not have link layer fault or channel failure if business has reply-attribute.
Embodiment of the invention emphasis point is to coordinate the method for link layer fault and channel layer fault; Method for link layer fault detect and channel layer fault detect is only done the generality explanation; Because in the industry cycle; Two kinds of testing mechanisms all have very fully to be realized, but also is in the exploratory stage for the effective Coordination Treatment of two kinds mechanism, and the user can effectively shorten the research and development time and reduce the cost of engineering construction.
Clearer more detailed for the present invention being described ground, describe with specific embodiment at present, in the subsequent implementation example, connect the link that promptly refers to preamble and connect.
Embodiment one: produce the link layer fault earlier, the back produces channel layer alarm scene, and referring to Fig. 2, handling process is as shown in Figure 3:
Embodiment two: produce channel failure earlier, the back produces link layer alarm scene, and referring to Fig. 4, handling process is as shown in Figure 5:
Channel alarm is received in step 502, connection, carries out channel alarm and detects, and confirms to exist channel failure;
If step 504 has been received the link layer fault then again, need to connect sign this moment and " both had channel failure, and had the link layer fault again "; But on loaded service, give the correct time in connection; Need to judge channel layer fault uploaded state,, then need not report if report; Because concerning the business that recovery is arranged, reporting of channel failure triggered professional recovery;
Receive that the link layer fault disappears or channel failure disappears if step 506 connects, connection can not report fault to disappear to loaded service, only removes local link corresponding layer malfunction or channel failure state and gets final product;
If the follow-up channel failure of this connection of receiving again of step 508 disappears or the disappearance of link layer fault, connection need report channel failure to disappear to loaded service.
Embodiment three: in the process that passage detects, produce link layer alarm scene, referring to Fig. 6, handling process is as shown in Figure 7:
Receive that the link layer fault disappears or channel failure disappears if step 706 connects, connection can not report fault to disappear to loaded service, only removes local link corresponding layer malfunction or channel failure state and gets final product;
If the follow-up channel failure of this connection of receiving again of step 708 disappears or the disappearance of link layer fault, connection need report channel failure to disappear to loaded service.
