For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 a is the method flow schematic diagram of first embodiment of the invention, comprising:
Step 11: test request direction test answer party sends LMM frame, carries test identification information in described LMM frame, described test identification information correspondence stream statistical rules.
In the embodiment of the present invention, in order to realize fine-grained loss packet test, in existing LMM frame, increased test mark (Test ID) information newly, this test identification information can indicate which information which stream to carry out loss packet test to according to.
Particularly, before loss packet test, in test request side and pre-configured test identification information and the corresponding relation flowing statistical rules in answer party can be tested.Stream statistical rules is used for showing to add up specific stream according to specific information, namely shows according to which information to which stream to add up.Such as, specific information can be that destination address (DA) according to service message and source address (SA) are added up, and specific stream can be DA_1 to DA and the service message that SA is SA_1 is added up.
Configure above-mentioned corresponding relation in test request side and test answer party after, test request side and test answer party can carry out respective handling according to this corresponding relation.Such as, for test request side, according to this corresponding relation, the test identification information be carried in LMM frame can be determined.Such as, the stream statistical rules of test identification information _ 1 correspondence is stream statistical rules _ 1, and stream statistical rules _ 1 particular content is: according to DA and SA, is DA_1 and the service message that SA is SA_1 is added up to DA.If then need according to DA and SA, DA is DA_1 and the service message that SA is SA_1 is added up time, test request side determine test identification information for test identification information _ 1, afterwards, test identification information _ 1 is carried in LMM frame and sends to test answer party.
Correspondingly, test answer party receives in LMM frame, obtain test identification information for test identification information _ 1, then can determine that corresponding stream statistical rules is according to above-mentioned corresponding relation: according to DA and SA, DA is DA_1 and the service message that SA is SA_1 is added up.Afterwards, test answer party statistics DA_1 and SA are the service message of SA_1 and are carried in LMR frame return to test request side by adding up the numerical value that obtains.
Further, test identification information in the embodiment of the present invention can adopt type lengths values (TypeLength Value, TLV) form, namely tests identification information and comprises: the value of the type of test identification information, the length of test identification information and test identification information.Above-mentioned stream statistical rules can comprise: the stream information of stream statistics foundation and statistic fluid, and stream statistics is according to showing according to which information to add up, and the stream information of statistic fluid shows to which stream to add up.Now, above-mentioned test identification information can comprise with the corresponding relation of stream statistical rules: test the type of identification information and flow the corresponding relation adding up foundation, and the corresponding relation of the test value of identification information and the stream information of statistic fluid.Now, stream statistics and the stream information with statistic fluid can be determined by the type of testing identification information respectively with the value of test mark, finally to obtain flowing statistical rules.
Step 12: test request side receives the LMR frame that described test answer party sends, and according to the statistical value of the service message carried in described LMR frame, and the statistical value of local service message carries out loss packet test to described LMR, the statistical value of the service message carried in described LMR frame is that the stream statistical rules that described test answer party is corresponding according to described test identification information is determined.
Further, also can carry test identification information in this LMR frame, test request side is after receiving LMR frame, first judge whether the test identification information carried in LMR frame is the test identification information that oneself sends, if so, then carry out loss packet test, otherwise the LMR frame of reception can be abandoned.
The computing formula of concrete loss packet test can be as follows:
Frame abandons
far-end=| TxFCf [t
c]-TxFCf [t
p] |-| RxFCf [t
c]-RxFCf [t
p] |
Frame abandons
near-end=| TxFCb [t
c]-TxFCb [t
p] |-| RxFC1 [t
c]-RxFC1 [t
p] |
Wherein, proximal measurement measures the number of dropped packets received with local terminal that opposite end sends, the number of dropped packets received with test request side of namely testing answer party transmission; Far-end measuring measures the number of dropped packets received with opposite end that local terminal sends, namely test request side send with the number of dropped packets of testing answer party and receiving.
TxFCf [t
c] be the transmission statistical value of service message of test request side when this sends LMM frame, RxFCf [t
c] for testing the reception statistical value of the service message of answer party when this receives LMM frame, TxFCf [t
p] be the transmission statistical value of the service message of test request side when last time sends LMM frame, RxFCf [t
c] for testing the reception statistical value of the service message of answer party when this receives LMM frame; TxFCb [t
c] for testing the transmission statistical value of the service message of answer party when this sends LMR frame, RxFC1 [t
c] be the reception statistical value of service message of test request side when this receives LMR frame, TxFCb [t
p] for testing the transmission statistical value of the service message of answer party when last time sends LMR frame, RxFC1 [t
p] be the reception statistical value of the service message of test request side when last time receives LMR frame.
Consider that above-mentioned two time points are because the initial service message statistical number of test request side and test answer party may be different, therefore use relative statistical number (as TxFCf [t
c]-TxFCf [t
p]) instead of absolute statistical number (as TxFCf [t
c]) carry out subtracting each other process.Certainly, if what will add up is cumulative number of dropped packets, absolute statistical number also can be adopted to carry out subtracting each other process, now, test request side and test answer party should carry out message number statistics from same starting point.
Above-mentioned test request side and test answer party can for supporting the equipment that the packet loss of OAM is measured, concrete as, test request side is any one in base station, switch, router, base station controller, and test answer party also can be any one in base station, switch, router, base station controller.

Step 22: test answer party, according to the corresponding relation of pre-configured test identification information with stream statistical rules, is determined the stream statistical rules that the test identification information that carries in described LMM frame is corresponding, and obtained the statistical value of service message according to described stream statistical rules.
Such as, pre-configured corresponding relation comprises: correspondence stream statistical rules _ 1, test identification information _ 1, and stream statistical rules _ 1 particular content is: according to DA and SA, is DA_1 and the service message that SA is SA_1 is added up to DA.Now, if the test identification information that carries is test identification information _ 1 in the LMM frame that receives of test answer party, then testing answer party by convection current statistical rules _ 1 particular content is: according to DA and SA, is DA_1 and the service message that SA is SA_1 is added up to DA.
Step 23: the statistical value of described service message is carried in LMR frame and sends to described test request side by test answer party, and described LMR frame is used to indicate described test request side and carries out loss packet test.
Further, test answer party can also carry test identification information in LMR frame, so that test request side carries out loss packet test when determining that the test identification information in the LMR frame received is the test identification information of test request side oneself transmission.Be understandable that, under normal circumstances, the test identification information carried in LMM frame can directly copy in LMR frame by test answer party.Certainly, in abnormal cases, testing answer party may will not be also that the test identification information that test request side sends is carried in LMR frame.
Further, above-mentioned stream statistical rules can be at least two.
The present embodiment is by determining according to the test identification information carried in LMM frame to flow statistical rules, this test identification information correspondence stream statistical rules, realize adopting stream statistical rules determination statistical value when loss packet test, instead of only add up according to vlan information in prior art, realize the fine granularity of loss packet test, according to different business statistics needs, the division of not homogeneous turbulence statistical rules can be carried out, and correct loss packet test can be carried out when various flows statistical rules.Further, whether test request side is that oneself sends by validation test identification information, can improve packet loss accuracy and saving resource further.

Test ID: take the byte number that " Length " indicates, represents the stream ID distributing to MEP (be specially test answer party) and add up, and is an integer value or MEP ID or according to other generate rule, distributes before measuring.On a MEP, Test ID is unique.
Step 33: test answer party judges the validity of the LMM frame received.
Test answer party can judge the validity of the LMM frame received in the following way:
If the MEG grade (concrete can obtain from the MEL field of LMM PDU) of the LMM frame received is greater than the MEG grade of oneself, forward according to OAM transparent forwarding principle Y.1731;
If the MEG grade of the LMM frame received is less than the MEG grade of oneself, think that invalid frame can be abandoned;
If the MEG grade of LMM frame received equals the MEG grade of oneself, judge that whether DA is oneself MAC Address, if so, be defined as valid frame and process, if not, being defined as invalid frame can be abandoned.
Step 34: test answer party, after the LMM frame determining to receive is effective, is determined corresponding stream statistical rules according to test identification information (Test ID TLV), and obtained statistical number according to this stream statistical rules.
Such as, the type of Test ID is 1, then can know that corresponding stream statistical rules is according to pre-configured information: add up according to DA+SA, in addition, suppose that the value of Test ID is 1, then DA=0000.0003.0004, SA=0000.0005.0008, therefore, the service message of statistics will be the service message of DA=0000.0003.0004 and SA=0000.0005.0008.
Step 35: test answer party produces LMR frame, and sends to test request side.
Wherein, the LMR PDU structure of this LMR frame can see Fig. 7.Particularly, the TxFCf value in LMM frame copies in the TxFCf field of LMR frame by test answer party, and is carried in TxFCb field by the transmission statistical number obtained according to above-mentioned stream statistical rules, reception statistical number is carried in RxFCf field.
In addition, the sa field of LMR frame is the MAC Address of test answer party;
The da field of LMR frame copies from the sa field of LMM frame;
The value of the Test ID of LMR frame copies from the Test id field of LMM frame;
The OpCode value of LMR frame is 42;
Other field in LMR frame can directly copy from LMM frame.
Step 36: after test request side receives LMR frame, judges the validity of LMR frame, and carries out loss packet test when LMR frame is effective.
Test request side can judge the validity of LMR frame in the following way:
If the MEG grade (concrete can obtain from the MEL field of LMR PDU) of the LMR frame received is greater than the MEG grade of oneself, forward according to OAM transparent forwarding principle Y.1731;
If the MEG grade of the LMR frame received is less than the MEG grade of oneself, think that invalid frame is abandoned;
If the MEG grade of LMR frame received equals the MEG grade of oneself, judge that whether DA is oneself MAC Address, if so, be defined as valid frame and process, if not, be defined as invalid frame and abandoned;
Judge that whether the Test ID of LMR frame is the Test ID that oneself sends, if not, also think this LMR frame is invalid and abandoned.
All the other situations, the MEG grade of the LMR frame namely received is identical with the MEG grade of oneself, and the DA of LMR frame is the MAC Address of oneself, and the Test ID in LMR frame is the Test ID that oneself sends, then determine that the LMR frame received is valid frame.
After determining that LMR frame effectively, test request side can obtain TxFCf field, RxFCf field and TxFCb field from LMR frame, and keeps in the current statistic value RxFC1 of the receive counter of this locality, test request side.Again adopt LMM frame to repeat above-mentioned test process, following formula can be adopted to carry out packet loss calculating by the LMM/LMR measuring process of twice:
Frame abandons
far-end=| TxFCf [t
c]-TxFCf [t
p] |-| RxFCf [t
c]-RxFCf [t
p] |
Frame abandons
near-end=| TxFCb [t
c]-TxFCb [t
p] |-| RxFC1 [t
c]-RxFC1 [t
p] |
Wherein, the implication of the parameter of above-mentioned packet loss calculating employing can see the related content in the first embodiment.
Be understandable that, in the present embodiment, Test id information represents with TLV form, also can adopt the form of fixed field, namely in LMM PDU and LMR PDU, increases a field respectively, and this field is used for carrying Test id information.Now, configuration is the corresponding relation flowing statistical rules and Test id information.Such as, compared to table 1 and table 2, corresponding relation now can be as shown in table 3:
