Abstract
The invention belongs to accurate Remote Defect instruction technical field and disclose a kind of Remote Defect instruction system accurate in multiple spot ETH connection, expanded by the TLV to CCM message tail end, its end of a period TLV from fixing is set to become the optional TLV that can customize, to will be in CCM message when RDI mark position 1, the subsidiary corresponding far-end fault MEP id information of RDI, can accurately indicate alarm under the scene of multiple spot ETH connection.In multiple spot ETH connection, RDI information can more accurately carry out remote alarm defect instruction, the CCM message for enabling the one end for receiving RDI more accurately to recognise that local terminal is sent receives exception in opposite end and results in RDI, to can be carried out effective alarm identifier and relevant treatment.
Description
Technical field
The present invention relates to accurate Remote Defects to indicate technical field, more particularly to a kind of accurately remote in multiple spot ETH connection
Hold error indicating system.
Background technique
The OAM under the scene of multiple spot ETH connection is detected at present, for any one MEP point, in local terminal fault message
When needing to pass to opposite end, it is identified by the position RDI in CCM message.Due to RDI only one, local terminal is informed
Whether there is alarm, the more information of related alarm can not be transmitted.Under the scene of multiple opposite ends, may alarm only and one of them
Opposite end is related, but each opposite end receive comprising RDI label CCM message when, can not judge specifically with which or
Which opposite end generates failure, to can not carry out accurately alerting judgement and processing, also actual end can not be presented to user
To the fault condition at end.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, provides a kind of accurately remote in multiple spot ETH connection
Error indicating system is held, by the LB/LT/TST message trailer for being changed to similar OAM in the fixed end of a period TLV field of CCM message tail end
The TLV field that can customize at end, and the corresponding opposite end MEP id information of alarm is specified in TLV field, to make opposite end MEP
Energy when receiving the CCM message comprising RDI information, can accurately know the corresponding MEP information of RDI, can effectively solve to carry on the back
The problems in scape technology.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
The present invention provides a kind of Remote Defect instruction system accurate in multiple spot ETH connection, comprising:
Expanded by the TLV to CCM message tail end, its end of a period TLV from fixing made to become the optional TLV that can customize,
To by when RDI mark position 1, the subsidiary corresponding far-end fault MEP id information of RDI connects in multiple spot ETH in CCM message
Alarm can be accurately indicated under logical scene.
As a preferred technical solution of the present invention, the LOC alarm generated for can not receive opposite end CCM message, with
And when receiving the information errors of clear opposite end, the MEP ID of opposite end will be passed through into TLV lattice while the position RDI 1 of CCM message
The tail end of formula addition local terminal CCM message；
When being alerted caused by the MEP ID mistake of opposite end CCM message for receiving and be unable to judge accurately specific opposite end,
The wrong MEP ID received is inserted in tail end TLV at MEP ID;
For receiving alarm caused by the MEG ID mistake of opposite end CCM message, 0 is inserted at MEP ID in tail end TLV.
As a preferred technical solution of the present invention, if there is multiple opposite end mistakes or more than a variety of situations produce simultaneously
It is raw, multiple MEP ID values are inserted at the TLV format MEP ID of CCM message tail end, each MEP ID value occupies 13, passes through
The length field value of TLV determines the number of MEP ID.
One or more technical solution provided in the present invention, at least has the following technical effect that or advantage:
1, when multiple spot ETH is connected to, RDI information can more accurately carry out remote alarm defect instruction, make the one end for receiving RDI
It can more accurately recognise that the CCM message that local terminal is sent results in RDI in opposite end reception exception, to can be carried out effective
Alarm identifier and relevant treatment.

The embodiment of the present application indicates that system solves the prior art by a kind of Remote Defect accurate when multiple spot ETH is connected to
In can not carry out accurately alert judgement and processing, also can not to user present actual fault condition end to end the problem of,
In multiple spot ETH connection, RDI information can more accurately carry out remote alarm defect instruction, keep the one end for receiving RDI more quasi-
True recognises that the CCM message that local terminal is sent results in RDI in opposite end reception exception, to can be carried out effective alarm mark
Knowledge and relevant treatment.
Technical solution in the embodiment of the present application, which is that solution is above-mentioned, can not carry out accurately alerting judgement and processing, also can not
The problem of actual fault condition end to end is presented to user, general thought is as follows:
One kind accurate Remote Defect when multiple spot ETH is connected to indicates system, comprising:
Expanded by the TLV to CCM message tail end, its end of a period TLV from fixing made to become the optional TLV that can customize,
To by when RDI mark position 1, the subsidiary corresponding far-end fault MEP id information of RDI connects in multiple spot ETH in CCM message
Alarm can be accurately indicated under logical scene；
The LOC alarm generated for can not receive opposite end CCM message, and when receiving the information errors of clear opposite end, by CCM
The MEP ID of opposite end is added to the tail end of local terminal CCM message while the position RDI 1 of message by TLV format；
When being alerted caused by the MEP ID mistake of opposite end CCM message for receiving and be unable to judge accurately specific opposite end,
The wrong MEP ID received is inserted in tail end TLV at MEP ID;
For receiving alarm caused by the MEG ID mistake of opposite end CCM message, 0 is inserted at MEP ID in tail end TLV；
If there is multiple opposite end mistakes or more than a variety of situations generate simultaneously, at the TLV format MEP ID of CCM message tail end
Multiple MEP ID values are inserted, each MEP ID value occupies 13, the number of MEP ID is determined by the length field value of TLV.
