Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in figures 1-4, the method for IP-RAN equipment fast detecting alarm link failure of the present invention, the business interface unit and main control unit of IP-RAN equipment realizes, comprises the following steps:
Step 1, formulate quick alarm link detecting agreement (Rapid Warning Link Detection Protocol, RWLDP), described quick alarm link detecting agreement is used for fast detecting alarm link failure, and it comprises: request message request and reply message reply;
Step 2, the business interface unit of IP-RAN equipment periodically sends request message request to the main control unit of IP-RAN equipment in alarm link port, and expects that main control unit replys this request message;
Step 3, if the business interface unit of IP-RAN equipment receives the reply message reply of main control unit, and correctly from reply message reply can extract detected field information, then think that this link of message transmission is at physics be all correct in logic, otherwise link will be identified as exception.
On the basis of technique scheme, as shown in Figure 2, request message request comprises: outside heading Outer herder and built-in message head Inner header, and the former is for supporting this technical scheme, wherein:
Outside heading Outer herder field, totally 12 bytes, for interleaving multiframe alignment signal MFAS field, support that 6 business interface unit interleave according to corresponding time slot altogether;
The MFAS field interleave 2 bytes, transmit corresponding service interface unit alarm link detecting protocol information respectively, are defined as " A1 ".
On the basis of technique scheme, as shown in Figure 3, reply message reply and comprise: outside heading Outer herder and built-in message head Inner header, the former is for supporting this technical scheme, wherein:
Outside heading Outer herder field, totally 12 bytes, for interleaving multiframe alignment signal MFAS field, detecting CHECK field;
The MFAS field interleave 2 bytes, transmit corresponding main control unit alarm link detecting protocol information, are defined as " A1 ";
The CHECK field interleave 2 bytes, altogether 16bit(bit), support the transmission of 16 business interface unit informations respectively.Every bit business transferring interface unit detection signal, ' 1 ' represents connection, and ' 0 ' expression is not communicated with.
On the basis of technique scheme, as shown in Figure 4, when business interface unit sends request message request to main control unit, multiframe alignment signal MFAS field is interleave in the outside heading Outer herder field corresponding time slot of request message request according to slot information, this protocol definition is " A1 ", the corresponding byte 1 ~ 2 of the MFAS field MFAS1 that slot 1 interleaves, the corresponding byte 3 ~ 4 of the MFAS field MFAS2 that slot 2 interleaves, the corresponding byte 5 ~ 6 of the MFAS field MFAS3 that slot 3 interleaves, the corresponding byte 7 ~ 8 of the MFAS field MFAS4 that slot 4 interleaves, the corresponding byte 9 ~ 10 of the MFAS field MFAS5 that slot 5 interleaves, the corresponding byte 11 ~ 12 of the MFAS field MFAS6 that slot 6 interleaves.
MFAS field MFASn in main control unit analysis request message, n=1 ~ 6, if the value of MFASn is effective, then the business interface unit of slot n is communicated with to main control unit one way link, otherwise is not communicated with.
Such as:
Business interface unit when effective (A1) the then slot 1 of the MFAS1 field value extracted is communicated with to main control unit alarm link one way link.
On the basis of technique scheme, each slot communication information that main control unit extracts according to the MFASn section extracted sends a reply message to business interface unit, and inserts CHECK field;
If slot 1 be communicated with CHECK field bit15 insert ' 1 ', otherwise insert ' 0 ', successively respectively insert slot 2 communication information to bit14, slot 3 communication information to bit13 ..., slot 16 communication information to bit0.
On the basis of technique scheme, business interface unit receives the reply message of main control unit, extract the CHECK field of outside frame head according to reply message format, if corresponding bit is ' 1 ', represent that connecting this business interface unit is communicated with the alarm link bidirectional between main control unit; Otherwise then represent that this main control unit is abnormal to business interface unit one way link.
Such as:
When business interface unit from reply message the CHECK field value that extracts for " 0x8000 ", then the business interface unit of slot 1 is to the alarm link bidirectional UNICOM between main control unit; When the CHECK field value extracted is " 0xF800 ", then the business interface unit of slot 1,2,3,4,5 is to all two-way UNICOM of alarm link of main control unit; When the CHECK field value extracted is " 0x0000 ", then main control unit is abnormal to the equal one way link of business interface unit of any slot.
The present invention utilizes the quick alarm link detecting agreement being exclusively used in fast detecting alarm link failure, makes user can detect ALM link failure quickly and easily, comprises short circuit, open circuit, unidirectional link failure, two-way link fault.The processing method of fault has: clock reparation, hardware reparation, load matched reparation.
This testing mechanism is realized by FPGA mode, and the IP-RAN serial equipment of Fiberhome telecommunication is applied, and successfully solves the problem of equipment fast detecting alarm link failure.
The content be not described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.
