Embodiment
The invention provides that a kind of (management of subnet layer network) realizes professional detection and Fault Locating Method and device based on NMS/SNMS, the NMS that utilizes webmaster the to provide detectability of service board to service signal of unifying is provided purpose, under the situation that does not insert instrument, carry out business fast and detect and fault location.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is the structure chart of wdm system, comprises optical terminal multiplexer (OTM) (optical sender end) 101, optical line amplifier (OLA) module 102 and OTM (optical receiver end) 103.OTM (optical sender end) 101 comprise transmitting terminal TX1, TX2, TX3 ..., TXn, light forwarding module, wave multiplexer, power amplifier (OBA), and Optical Supervisory Channel sending module.The signal of each transmitting terminal emission through be converted to behind the corresponding light forwarding module wavelength be λ 1, λ 2, λ 3 ..., the light signal of λ n, the light signal of all wavelengths enters OBA through behind the wave multiplexer.For the signal that sends from OBA, the Optical Supervisory Channel sending module is monitored.OLA 102 comprises OLA and Optical Supervisory Channel transmission/receiver module, and Optical Supervisory Channel transmission/receiver module is used for received signal from the circuit, after handling, re-sends on the circuit.OTM (optical receiver end) 103 comprise receiving terminal RX1, RX2, RX3 ..., RXn, light forwarding module, channel-splitting filter, light preamplifier (OPA), and Optical Supervisory Channel receiver module.The Optical Supervisory Channel receiver module receives the light signal that sends to OPA from circuit, and the light signal of its reception is monitored.OPA sends to channel-splitting filter with the light signal that receives, channel-splitting filter with light signal be decomposed into wavelength be λ 1, λ 2, λ 3 ..., the light signal of λ n, the light signal after the decomposition through arrive behind the corresponding light forwarding module corresponding receiving terminal RX1, RX2, RX3 ..., RXn.Among Fig. 1, OLA and OBA, and be optical transport layer (OTS) between OBA and the OPA, between wave multiplexer and the channel-splitting filter optical multiplex layer, be the beam split channel layer between the light forwarding module of the light forwarding module of OTM (optical sender end) 101 and OTM (optical receiver end) 103.
In the system shown in the accompanying drawing 1, create business, realize detection and failure location to business.
Fig. 2 has shown the flow process of the Fault Locating Method based on business provided by the invention, comprising:
On webmaster, can or manually connect and create the business of a SNMS by the automatic service search, this business has comprised that client signal (promptly uses the service signal of wave-division device transmission, STM64 for example, GE, business such as POS) all veneers of process in wdm system, according to this business, add the detectability that the service class veneer possesses to service signal, light amplification class veneer and close the luminous power detectability of partial wave class veneer to channel signal in the transmission course constitutes the basis of Fault Locating Method among the present invention.The business of setting up in the present embodiment is to be converted to the light signal that wavelength is λ 1 after the signal of transmitting terminal RX1 passes through the light forwarding module, arrives the business of receiving terminal RX1 behind the light modular converter of this light signal process wave multiplexer, OBA, OLA, OPA, channel-splitting filter and receiving terminal RX1 correspondence.
Carrying out before test command begins, at first needing to detect the detection whether veneer in the SNMS relevant connection exist alarm to cause present embodiment to set up business can't carry out.Under the situation that does not exist some alarms that have a strong impact on service delivery to exist (for example No Light Alarm), veneer (RX1 place veneer) the configuration testing initiation command of veneer that webmaster begins to business (TX1 place veneer) and service ending.
Veneer TX1 that webmaster is given in professional original position and the veneer RX1 in the service ending position issue and stop test command, the veneer (TX1) of professional starting end stops the insertion of PRBS, configuration status before recovering to detect, the veneer of service ending end also stops the detection to PRBS, the configuration status before recovering to detect.
The detailed process of step 203 comprises as shown in Figure 3:
This service signal must be basic identical with the signal of actual needs transmission.Because like this, on whole SNMS, all intermediate node veneers can keep the state of normal operation and not need to do particular processing.And sort signal such as concerning wdm system, can be encapsulated into pseudo-random code sequence (PRBS) signal that produces in the payload of optical transfer network (OTN) and transmit.PRBS has different sequences, in order to guarantee the effective detection of professional receiver side to signal, need be configured to veneer by the webmaster unification in step 202.
The time of test may be very long, for example 72 hours, webmaster is collected performance and the alarm that SNMS goes up related single-boards, if the veneer at receiving terminal does not detect any alarm and error code, then proof detects and passes through smoothly, professional on wdm system transmission normal, otherwise analyze and locate the position of failure judgement point by the alarm correlation principle.
Position according to existing alarm localization method.
What introduce above is testing process to one way traffic, for two-way services, the principle of its processing is identical, for example, that is to say to have possessed reception and the transmission of OCH on veneer simultaneously for the two-way veneer of single channel, at this moment can create two-way services, veneer can be carried out the insertion of PRBS at the OCH_OUT port, in the detection of OCH_IN port execution PRBS, equally can finish detection and diagnosis location to two-way services.
The present invention also provides the fault locator based on business, is used for the WDM/DWDM system, comprising: business is set up module 401, is used to set up the business based on WDM/DWDM; Alarm detection module 402, be used to detect the alarm whether veneer in the SNMS relevant connection exists the test that causes described business to carry out, if then do not start the beginning test module and stop test module, if not, then start the beginning test module and stop test module; Beginning test module 403 is used for by the veneer in the service ending position test signal that the veneer in professional starting position produces being tested, and provides test result; Stop test module 404, be used to stop test described business.
The detailed structure of beginning test module 403 comprises as shown in Figure 5: the test initiation command issues module 501, is used for issuing the test initiation command to veneer and the veneer in the service ending position in professional starting position; Test signal generation module 502, the veneer in professional starting position produces test signal; Test signal detection module 503, the veneer in the service ending position detects described test signal; Test result provides module 504, according to testing result, provides test result.
Those skilled in the art can also carry out various modifications to above content under the condition that does not break away from the definite the spirit and scope of the present invention of claims.Therefore scope of the present invention is not limited in above explanation, but determine by the scope of claims.
