Description
Technical field
The present invention relates to TMPLS (Transport Multi-protocol Label Switching transmits multiprotocol label switching) technology, relate in particular to a kind of positioner and method of failure of connectivity.
Background technology
At TMPLS technology and PBT (Provider Backbone Transport, the provider backbone transmission) in the technology, introduced TMS (Section Level of TMPLS), TMP (Path Level of TMPLS) and three layers of LSP (Label Switch Path of TMC (Custom Level of TMPLS), label switched path), behind configuration LSP, detect LSP and whether dispose normally, then need to introduce detection of connectivity.In the OAM of TMPLS and PBT (operation, management are safeguarded) mechanism, realize connective detection by enabling CV (ConnectivityVerification, connective affirmation) mechanism.Though CV mechanism can detect various connective alarms (loss of connectivity for example, mistake merges, maintenance entity terminal point identifier (MEP ID) mismatch, the cycle mismatch), but present CV testing mechanism, can't clearly distinguish when Su Duan detects this class alarm, be which node in network is introduced these alarms on earth.
Present CV operating mechanism as shown in Figure 1, current operating mechanism has following defective: when place end maintenance entity terminal point (MEP) detects connectivity when alarm, can't inform the user, fault is at that or which node at networking to introduce on earth.
Summary of the invention
Technical problem to be solved by this invention is, a kind of positioner of failure of connectivity is provided, and a kind of localization method of failure of connectivity is provided, and the present invention can be when wrong running fire be given birth to, clearly the wrong node location that is connected in the network in location.
A kind of positioner of failure of connectivity, comprise source end MEP CV transtation mission circuit successively, maintenance entity intermediate node (MIP), place end MEP CV receiving circuit and destination node testing circuit, also comprise MIP testing circuit and fault location circuit, described MIP testing circuit and destination node testing circuit are used for detecting the connective of coupled node and alarm are sent to described fault location circuit; Described fault location circuit is used for the position that failure judgement occurs.
A kind of localization method of failure of connectivity may further comprise the steps:
Step 1: source end MEP CV transtation mission circuit periodically sends the CV frame, and whether the MIP testing circuit detects the CV frame that this node receives connective alarm, if then alarm is sent to the fault location circuit; Otherwise, continue to detect;
Step 2: place end MEP CV receiving circuit termination CV frame, whether the destination node testing circuit detects this frame connective alarm, if then alarm is sent to the fault location circuit; Otherwise, continue to carry out this step;
Step 3: the fault location circuit is according to the alarm type of MIP testing circuit and destination node testing circuit, the position that failure judgement takes place.
Also comprise before the described step 1: MEP ID, MEG ID, the sense cycle of MEP ID, maintenance entity group identifier (MEG ID), transmission cycle and the destination node MEP of source node MEP, the MIP MEP of configuration CV.
In the described step 3, the method for the position that fault location circuit judges fault takes place is as follows:
Whether first MIP of fault location electric circuit inspection has connective alarm, and whether if then fault occurs in source MEP, otherwise detecting second MIP has connective alarm, if then fault occurs in first MIP, by that analogy, the position that fault location takes place.
Connective alarm described in this method comprises: connectivity is lost, mistake merges, MEP ID mismatch and cycle mismatch.
The present invention can effectively detect all kinds of alarms in the CV function running, and time of fault location and network recovery has been shortened in the rapid position of tracing trouble in network.
