The method that the embodiment of the invention provides based on the registering passive optical network of Ethernet; Safeguard standard owing to can utilize mutual message judgement based on the expansion operation management of the device use of the registering passive optical network of Ethernet; And according to the corresponding expansion of judged result selection activation operation management maintenance state machine; The device based on the registering passive optical network of Ethernet that makes that the embodiment of the invention provides can adapt to the demand of different operators, and each stage is used independent state machine, is activated by the state machine in a last stage; Three phases is relatively independent, can only revise separately to some stages.
The method based on the registering passive optical network of Ethernet that the embodiment of the invention provides uses a state machine to realize respectively to the agreement of three different registration phases; Sequencing according to registration phase; Use certain communication mechanism to activate each state machine successively; Realize the decoupling zero of each registration phase, Fig. 1 for the embodiment of the invention provide based on state of activation machine example schematic in the method for the registering passive optical network of Ethernet:
The initial condition of Multi-point Control Protocol state machine 101, standard operation management maintenance state machine 102, Japan's expansion operation management maintenance state machine 103, telecommunications expansion operation management maintenance state machine 104 and UNICOM's expansion operation management maintenance state machine 105 is unactivated state.
Detect the LLID (LLID, Logical Link Identity) of queued for log-on in addition, then activate Multi-point Control Protocol state machine 101; Activate Multi-point Control Protocol state machine 101 and activate back activation standard operation management maintenance state machine 102; Critical field judgement according to mutual message is safeguarded standard based on the expansion operation management of the device use of the registering passive optical network of Ethernet; From Japan's expansion operation management maintenance state machine 103, telecommunications expansion operation management maintenance state machine 104, UNICOM's expansion operation management maintenance state machine 105, select corresponding expansion operation management maintenance state machine to activate; Suppose that judged result is that standard is safeguarded in telecommunications expansion operation management, then selects to activate telecommunications expansion operation management maintenance state machine 104.Local side can be every be inquired the device based on the registering passive optical network of Ethernet that whether need reach the standard grade at a distance from 5 seconds.If not do not respond then device that explanation does not have to reach the standard grade based on the registering passive optical network of Ethernet based on the device of the registering passive optical network of Ethernet.If someone responds, local side can be mutual with it, accomplishes registration process.
After starting the MPCP state machine, behind the inquiry message of receiving local side (discovery_gate), can respond based on the device of the registering passive optical network of Ethernet.
Safeguard the concrete example of standard based on the expansion operation management of the device use of the registering passive optical network of Ethernet according to the critical field judgement of mutual message: like the unique indications (OUI that organizes that obtains through standard OAM registration phase; Which kind of expansion OAM agreement what organizationally Unique Identifier), can confirm that local side uses is.
Fig. 2 is the method flow diagram based on the registering passive optical network of Ethernet that the embodiment of the invention provides, and comprising:
201, detecting the LLID whether queued for log-on is arranged, is execution in step 202 then; Otherwise return step 201.
202, activate the Multi-point Control Protocol state machine.
Activate the MPCP state machine to this LLID.
Each has only a cover based on the registration code of the device of the registering passive optical network of Ethernet, but that LLID has is a plurality of.Be that code has only a cover, data have many covers, can only have a LLID to register simultaneously.
203, judge activating whether success, is execution in step 205 then; Otherwise execution in step 204.
204, the login state of this LLID is moved back to initial condition, execution in step 202.
205, activate standard operation management maintenance state machine, with the deexcitation of Multi-point Control Protocol state machine.
206, after arriving preset time, whether criterion operation management maintenance state machine brings into operation, and is execution in step 207 then, otherwise execution in step 204.
Just because the EPON system must accomplish MPCP, standard OAM simultaneously and expansion 3 stages of OAM succeed in registration, for " prevent that the preceding state machine from having accomplished and by deexcitation, a back state machine is activated; but the not operation because there being mutual message causes system to be hung extremely " situation, therefore; After the preceding state machine activates a back state machine, can use timer, check whether a back state machine moves; If a back state machine is operation not; Then the login state of corresponding LLID is moved back to initial condition, all state machines of deexcitation are simultaneously waited for registration next time.
Have only a cover registration code on the device based on the registering passive optical network of Ethernet, promptly 3 state machines are each one, but a plurality of LLID might be arranged, and each LLID has preserved a state value to each state machine.If LLID is at each stage registration failure, the LLID state value that state machine that need the front is successful is corresponding all makes initial condition into, so that register again next time.
Deexcitation is meant, if registration failure is all moved back to state at the beginning to all state machine state that LLID is corresponding.
207, safeguard standard according to mutual message judgement based on the expansion operation management of the device local side use of the registering passive optical network of Ethernet.
When activating according to preceding two state machines, in the mutual message based on the device of the registering passive optical network of Ethernet and local side, the expansion operation management maintenance standard that local side uses can be judged in the keyword that carries.
208,, activate corresponding expansion operation management maintenance state machine according to judging the expansion operation management maintenance standard that obtains.
209, after arriving preset time, judge whether expansion operation management maintenance state machine brings into operation, be execution in step 210 then, otherwise execution in step 204.
210, the notice higher level equipment is accomplished based on the registering passive optical network of Ethernet.
Flow process finishes.
