Embodiment
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.
802.3ah agreement, promptly (operations administration and maintenance, two-layer protocol OAM) are monitoring and the instrument that solves network problem to Ethernet (Ethernet) Operations,Administration And Maintenance.It can make more effectively supervising the network of network manager at the state of data link layer reporting ent.At present, OAM mainly solves the OAM problem of last kilometer ethernet equipment, comprises link performance monitoring, detecting fault and alarm, go-and-return test, the request of telemanagement information bank (mib) variable.
The present invention in a kind of simple and reliable mode, reaches the purpose of the link detecting that realizes telecommunication apparatus better, active and standby detection and protection by improved 802.3ah agreement.
802.3ah protocol massages after the improvement as shown in Figure 1, in information (information) message, increased information TLV field newly, comprise two information value among the TLV, one is the information value of local terminal, and another is the information value of opposite end; The activestandby state (master slave status) that comprises local terminal among the information value of local terminal comprises the activestandby state of opposite end among the information value of opposite end; Activestandby state (master slave status), the current activestandby state of the local and opposite end of expression if value is 1, then is expressed as main usefulness, if value is 0, then is expressed as standbyly, if be other values, then represents state the unknown; Also comprise newly-increased project data terminal equipment (DTE) ID among the TLV, ID number of the local and opposite end DTE equipment of expression is if two ends then with the size of DTE ID which the DTE equipment of making a strategic decision are responsible for initiation and are switched because active and standby matching do not switched; Because need to set up constraint or prompting in actual disposition or in the link setup negotiations process, two ends DTE ID can not equate.
As shown in Figure 2, be the active and standby flow chart with the Interface Matching method of the present invention, this method comprises:
For the active and standby unmatched situation of terminal device of butt joint, drawn by master slave status field in the information message of two ends DTE equipment judgement OAM: the status word segment value of terminal device is inconsistent, then shows active and standby not matching; And determine according to less strategy of DTE ID or the bigger strategy of DTE ID whether the decision-making of end equipment notice upper system initiates masterslave switchover, and the factor of decision-making comprises whether the OAM link of former spare interface is in normal condition etc.;
In addition, if identifying less strategy with DTE switches and is example, if a side who preferentially switches according to the DTE-ID decision-making can not initiate to switch because of local cause specific (fault etc.), then maximum limit is revised as with DTE-ID in this locality temporarily, and by information message notifying the other side, initiated switch by the other side according to former decision-making mechanism this moment; After switching end, this locality is re-set as normal value with DTE-ID;
Similarly, be example as if switching with the big strategy of DTE sign, if a side who preferentially switches according to the DTE-ID decision-making can not initiate to switch because of local cause specific (fault etc.), then minimum limit value is revised as with DTE-ID in this locality temporarily, and by information message notifying the other side, initiated switch by the other side according to former decision-making mechanism this moment; After switching end, this locality is re-set as normal value with DTE-ID;
For the situation of the current master of terminal device of docking with optical fiber transmitting-receiving single-pass, OAM agreement itself can detect unusual with the form of emergency (Critical Event) or link failure urgent link event messages such as (Link Fault) and notify the opposite end.At this moment, detecting this unusual end simultaneously should notify upper system initiatively to initiate masterslave switchover, receive an end of urgent link event, also should notify upper system to initiate masterslave switchover, and notify the other side with incident (event) message (perhaps special masterslave switchover message) mutually;
After step 202, the masterslave switchover success, the equipment of initiating to switch sends to opposite end with the active and standby of self with state by Status Flag field and identification field newly-increased in the infomational message, if the active and standby state consistency of using of terminal device, the then active and standby Interface Matching of using.
After switching successfully, reset local terminal local master the value of slave status be currency, by information message notifying the other side.

As shown in Figure 4, for the present invention does not realize the schematic flow sheet that negotiation is switched corresponding to active and standby the matching of terminal device under the scene shown in Figure 3, this process comprises:
The OAM link detecting is enabled at step 401:A, B two ends, and the A1 port periodically sends the infomation message to the B1 port: local master/slave status word segment value is 1;
Step 402:B1 port also can periodically send the information message to the A1 port: local master/slave value is 0;
Step 403:A2 port sends the information message to the B2 port: local master/slave value is 0;
Step 404:B2 port sends the information message to the A2 port: local master/slave value is 1;
Active and standby unmatched phenomenon is found by the activestandby state field of comparison local terminal and opposite end in step 405:A and B two ends.Initiate to switch by B end notice upper strata by comparison DTE ID decision-making.B end generally should be judged current reserve link whether available (whether the OAM link setup is normal), if available, then initiates masterslave switchover;
Behind the step 406:B end masterslave switchover, B1 becomes main usefulness, and B2 becomes standby, and B1 sends the infomation message to the A1 port: local master/slave value is 1; The active and standby coupling of A1 and B1, professional logical;
Send the infomation message between step 407:B2 and A2 port mutually: local master/slave value is 0; The active and standby coupling of A2 and B2, professional logical.
