The method comprises the following steps: the GPON system firstly judges the access mode of system configuration, when the access mode is silent mode, the registration operation of the ONU is completed mutually by a manager; and when the access mode is polling mode, an OLT performs registration operation periodically, wherein the operation comprises the following steps: 1. the OLT automatically searches a new ONU and writes the serial number of the newly searched ONU in a serial number discovery table; and 2. the OLT filters the serial number discovery table, measures the distances of the residual ONUs, activates the ONUs and establishes a communication channel between each activated ONU and OLT. The registration method of the ONU in the GPON system of the invention provides two access modes and three registration modes; the silent mode is applicable to the condition that the number of ONUs is small and the ONUs are stable, the polling mode is applicable to the other conditions; and the three registration modes are applicable to different security levels, thus increasing the flexibility of the registration function of the ONU of the GPON system.
Description
Technical field
The present invention relates to the registration policy of ONU (optical network unit) in GPON (gigabit passive optical network) system, the register method of ONU in a kind of specifically GPON system.
Background technology
Along with the continuous development of the Internet, each operation commercial city is in the construction of strengthening its broadband network, and number of users also increases rapidly.For operator, selecting simply and easily, subscriber registration mode is a necessary process of implementing user management and accounting management; The user also wishes to authenticate simple and fast, charging policy is versatile and flexible.
The GPON system directly links to each other with user side as access device, and realizing in the GPON system has important effect to the registering functional of ONU.And unified registration technology do not arranged in the GPON system at present as yet, and existing these registration technologies all can't be realized the control to ONU, promptly can't discern legal and disabled user, ONU to all connections authorizes, may cause disabled user's generation like this, be unfavorable for the management of operator the user.
Summary of the invention
At problems of the prior art, the object of the present invention is to provide the register method of ONU in a kind of GPON system, solution can't realize the control to ONU when having in GPON system ONU registration now, the ONU of all connections is authorized, and can't discern legal and the problem disabled user.
For reaching above purpose, the technical scheme that the present invention takes is:
The register method of ONU in a kind of GPON system is characterized in that may further comprise the steps:
The access module of system configuration is at first judged by the GPON system, when access module is Quiet_mode, registration operation to ONU is finished by hand by administrative staff: administrative staff need be known the sequence number of new ONU to be operated in advance, then the sequence number of new ONU is informed the PON chip among the OLT, and making OLT that this ONU is carried out corresponding operating, its bottom operation is realized by the PON chip;
When access module was Polling_mode, OLT periodically registered operation to ONU, and in one-period, described ONU registration process comprises following two steps:
The first step, OLT finds new ONU automatically, and with the sequence number writing sequence number table of discovery of newfound ONU;
In second step, OLT uses the control corresponding table that the sequence number table of discovery is filtered according to the registration mode of system configuration, and to failing to filter the ONU that passes through, OLT does not register operation; Find range earlier to filtering the ONU that passes through, to obtain the balanced time delay that requesting activation ONU needs, work as ranging success, and after ONU receives the Ranging_Time message of OLT transmission, ONU is activated by OLT, and set up the communication port that is activated between ONU and the OLT, promptly finished one this moment and taken turns the registration operation of ONU.
On the basis of technique scheme, when finish one take turns registration operation after, after OLT waits for a period of time according to the value of parameter interval of configuration, begin the operation of next round again, the wheel number of ONU registration process operation is by the parameter c ycle decision of configuration, when the value of parameter c ycle is zero, the expression Infinite Cyclic; When the value of parameter c ycle is positive integer and is not equal to for the moment, OLT carries out earlier one and takes turns the registration operation of ONU, and the value of parameter c ycle subtracts one then, when the value of parameter c ycle equals for the moment, represent the wheel number of registration process operation to use up, the GPON system enters Quiet_mode automatically.
On the basis of technique scheme, registration mode comprises described in second step:
(1) no certification mode NA_mode in this pattern, need not verify ONU, and current online, visible ONU all can be activated; Online ONU represents all ONU on the current ODN of hanging over; As seen ONU represents the ONU that enabled, and when ONU was gone to enable, the laser of this ONU cut out, and opens when enabling;
(2) pure sequence Mode S N_mode, under this pattern, OLT verifies the legitimacy of ONU according to the sequence number of ONU;
(3) sequence number+cipher mode SP_mode, under this pattern, the legitimacy that OLT verifies ONU according to sequence number and the password PAS of ONU;
Control table comprises white list, blacklist, bad password table described in second step, and in three kinds of registration mode under Polling_mode, NA_mode only uses blacklist that ONU is filtered; SN_mode uses blacklist and white list that ONU is filtered; SP_mode uses white list, blacklist and bad password table that ONU is filtered, and three kinds of shared blacklists of registration mode filter ONU.
On the basis of technique scheme, OLT is current according to the configuration determination of parameter visi_mode and auth_mode to be which kind of access module and registration mode, and when visi_mode=0, the configuration access pattern is a stillness mode; When visi_mode=1, be configured to poll pattern; When auth_mode=0, the configuration registry pattern is NA_mode; When auth_mode=1, be configured to SN_mode; When auth_mode=2, be configured to SP_mode.
On the basis of technique scheme, when OLT realized that the ONU registration admits function and registration to remove function, the control table of use had three kinds, is respectively:
Blacklist is used to deposit the sequence number of illegal ONU, and the ONU of sequence number in this table will be gone to enable;
White list, white list are used to deposit the sequence number of legal ONU, and the ONU of sequence number in this table will be allowed to range finding;
Bad password table, bad password table generate in SP_mode password authentification process automatically, when the password authentification mistake activation of ONU is unsuccessful, the sequence number of this ONU are put into the bad password table.
On the basis of technique scheme, after ONU was activated, its sequence number was stored in the activation table, avoided this ONU to be repeated to activate,
When OLT detected single ONU chain rupture, OLT deleted the sequence number of this ONU automatically from activation table and sequence number table of discovery,
When OLT detected all link chain ruptures, OLT removed whole sequence table of discovery and activation table automatically.
On the basis of technique scheme, the method for manager works ONU is:
When access module was Quiet_mode, when ONU was activated, administrative staff informed OLT with the ONU sequence number, and made OLT that this ONU is carried out activation manipulation, and OLT to this ONU range finding, finishes the activation of this ONU automatically; During to the ONU deexcitation, administrative staff inform OLT with the ONU sequence number, and make OLT that this ONU is carried out deactivating operation, and OLT sends Deactive_ONU-ID message automatically to this ONU deexcitation; When ONU was gone to enable, administrative staff informed OLT with the ONU sequence number, and made OLT that this ONU is gone enable operation, and OLT sends the laser that the Disable_serial_number message that has " Disable " option is closed this ONU automatically; When ONU was enabled, administrative staff informed OLT with the ONU sequence number, and made OLT that this ONU is carried out enable operation, and OLT sends the laser that the Disable_serial_number message that has " Enable " option is opened this ONU automatically;
When access module was Polling_mode, administrative staff controlled the state of ONU by editor's control table; When ONU is activated, the sequence number of ONU is added in the white list, OLT activates this ONU automatically by above-mentioned flow process; During to the ONU deexcitation, the sequence number of ONU is deleted from white list, OLT sends Deactive_ONU-ID message automatically to this ONU deexcitation; When ONU is gone to enable, the sequence number of ONU is added in the blacklist, OLT sends the laser that the Disable_serial_number message that has " Disable " option is closed this ONU automatically; When ONU is enabled, the sequence number of ONU is deleted from blacklist, OLT sends the laser that the Disable_serial_number message that has " Enable " option is opened this ONU automatically.
On the basis of technique scheme, following parameter default configuration is
visi_mode＝1，
auth_mode＝1，
cycle＝0，
interval＝5s，
Max_discover=10, described max_discover is used to limit the degree of depth of sequence number table of discovery.
The register method of ONU in the GPON of the present invention system, provide a cover the complete ONU of GPON system registration policy, the invention provides these two kinds of access modules of Quiet_mode and Polling_mode, under Quiet_mode, registration operation to ONU is finished by hand by administrative staff, it is applicable to that ONU quantity is few, and the stable situation of member; In other cases, adopt Polling_mode, under Polling_mode, OLT periodically registers operation to ONU.Under this visit pattern (Polling_mode), no certification mode (NA_mode), pure sequence pattern (SN_mode) and three kinds of registration mode of sequence number+cipher mode (SP_mode) are provided again, the registration mode of different level of securitys can be provided respectively.Administrative staff can select different access modules and registration mode according to actual needs, have improved the flexibility of the ONU of GPON system registering functional.

Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
For satisfying the different demand of user, the register method of ONU in the GPON of the present invention system, stillness mode (Quiet_mode) and two kinds of access modules of poll pattern (Polling_mode) are provided, and the no certification mode (NA_mode) under Polling_mode, pure sequence pattern (SN_mode) and three kinds of registration mode of sequence number+cipher mode (SP_mode).
The registering functional of ONU comprises two subfunctions in the said GPON of the present invention system: registration admits function and registration to remove function, registration admits function promptly to activate ONU, and be communication port between its foundation and the OLT, registration is removed function and is promptly interrupted communication port between ONU and the OLT.
The registration process of ONU can be summarized as follows in the said GPON of the present invention system:
The access module of system configuration is at first judged by the GPON system:
When access module is Quiet_mode, the registration operation of ONU is finished by hand by administrative staff.Administrative staff need be known new ONU sequence number in advance, will wait to operate the ONU sequence number then and inform PON chip (hereafter is OLT) among the OLT, and make OLT that this ONU is carried out corresponding operating, and its bottom operation is realized by the PON chip.During to ONU activation or deexcitation, administrative staff inform OLT with the ONU sequence number, and make OLT that this ONU is activated or deactivating operation; To ONU enable or when going to enable same only the need ONU sequence number is informed OLT, and make OLT that this ONU is enabled or go enable operation.
When access module was Polling_mode, OLT periodically registered operation to ONU, and in one-period, described ONU registration process comprises following two steps:
The first step, OLT finds new ONU automatically, and with newfound ONU writing sequence number table of discovery;
In second step, OLT uses the control corresponding table that the sequence number table of discovery is filtered according to the registration mode of system configuration, and to failing to filter the ONU that passes through, OLT does not register operation; Find range earlier to filtering the ONU that passes through, to obtain the balanced time delay that requesting activation ONU needs, work as ranging success, and after ONU receives the Ranging_Time message of OLT transmission, ONU is activated by OLT, and set up the communication port that is activated between ONU and the OLT, promptly finished one this moment and taken turns the registration operation of ONU.Three kinds of registration mode are arranged under Polling_mode, be respectively NA_mode, SN_mode and SP_mode, in second step, under the different registration mode, use different control tables that the sequence number table of discovery is filtered.See follow-up explanation for details.
On the basis of technique scheme, when finish the first step, second the step this two the step after, so far, one takes turns the registration operating process finishes, when finish one take turns registration operation after, after waiting for a period of time, the operation of beginning next round, this section stand-by period, the wheel number of registration process operation was by the parameter c ycle decision of configuration by the parameter interval decision of configuration, after the wheel number of registration process operation used up, the GPON system entered Quiet_mode automatically.The concrete setting and the implication thereof of each parameter see follow-up explanation for details.
On the basis of technique scheme, administrative staff can control the state of ONU by editor's control table.When ONU is activated, the sequence number of ONU is added in the white list; During to the ONU deexcitation, the sequence number of ONU is deleted from white list.When ONU is gone to enable, the sequence number of ONU is added in the blacklist; When ONU is enabled, the sequence number of ONU is deleted from blacklist.
The GPON agreement is based on the sequence number of ONU and discerns and dispose ONU's.Under the situation of the sequence number of knowing ONU in advance, adopt the mode that directly activates ONU usually.And in other cases, the sequence number of ONU can not be known in advance, so OLT needs to find automatically the sequence number of ONU.The present invention has defined two kinds of access modules according to demand:
(1) stillness mode (Quiet_mode) is used for manual registration, and administrative staff directly register operation to ONU, and mode is simple, directly perceived, and it is the static state operation to ONU, is applicable to that ONU quantity is few, and the stable situation of member, and is generally not open to the end user; Administrative staff need be known the sequence number of waiting to operate ONU in advance, then sequence number are informed OLT, and make OLT that this ONU is carried out corresponding operating, and its bottom operation is realized by the PON chip;
(2) poll pattern (Polling_mode), be used for automatic registration, it can periodically obtain the sequence number (can handle by the method that the GPON standard is write exactly) of the ONU that newly reaches the standard grade, and with in their adding sequence number table of discoveries, OLT compares by the sequence number that will write down in sequence number in the sequence number table of discovery and the control table then, judges the legitimacy of ONU and activates legal ONU.So far, the epicycle registration process is finished, after waiting for a period of time, and the operation of beginning next round.More than operation is that OLT finishes automatically.
Three important parameters are arranged under poll pattern, and cycle represents the wheel number of system's operation registration process, when initial value is defined as zero, and the expression Infinite Cyclic.Be defined as other positive integer and be not equal to a period of time, press the actual count operation, carry out a registration process earlier, judge whether the cycle value is one, not for for the moment the cycle value being subtracted an operation, carry out registration process again one time, judge once more whether the cycle value is one, or not do not carry out registration process next time again for again the cycle value being subtracted an operation for the moment, so circulation, until the cycle value is one, when the cycle value is for the moment, no longer it is subtracted an operation, and carried out registration process this moment earlier, equate with the cycle value that begins most so carry out number of times; Interval represents that this takes turns the time interval between beginning to begin to next round; Max_discover defines the degree of depth of sequence number table of discovery.The concrete setting of max_discover sees follow-up explanation for details.
Under poll pattern, this programme has proposed three kinds of registration mode:
(1) no certification mode (NA_mode) in this pattern, need not be verified ONU, and current online, visible ONU all can be activated; Online ONU represents all ONU on the current ODN of hanging over; As seen ONU represents the ONU that enabled, and when ONU was gone to enable, the laser of this ONU cut out, and opens when enabling, and whether the enabling of ONU controlled by blacklist;
(2) pure sequence pattern (SN_mode), under this pattern, OLT verifies the legitimacy of current online, visible ONU according to the sequence number of ONU;
(3) sequence number+cipher mode (SP_mode), under this pattern, OLT verifies the legitimacy of current online, visible ONU according to the sequence number of ONU and password (PAS).
The keeper disposes access module and the registration mode of ONU in OLT.Defined parameters visi_mode and auth_mode, configuration access pattern and registration mode come down to the assignment to visi_mode and auth_mode.
When visi_mode=0, the configuration access pattern is a stillness mode; When visi_mode=1, be configured to poll pattern.
When auth_mode=0, the configuration registry pattern is NA_mode; When auth_mode=1, be configured to SN_mode; When auth_mode=2, be configured to SP_mode.
Realize that the control table that the ONU registering functional is used has three kinds: blacklist, white list, bad password table.Also can adopt prior art to merge into these three kinds of tables a kind of.
(1) blacklist: be used to deposit the sequence number of illegal ONU, the ONU of sequence number in this table will be gone to enable.When ONU was gone to enable, the laser of ONU was closed.When ONU was enabled, laser was opened.Blacklist is all used in three kinds of registration mode, and three kinds of shared blacklists of registration mode filter ONU.
When in blacklist, having added the member, directly this ONU is gone to enable, even this ONU activates; If in blacklist, during removing members, then directly this ONU is enabled.
(2) white list: the sequence number that is used to deposit legal ONU.It is used for SN_mode and SP_mode, and the ONU of sequence number in this table will be allowed to range finding.
(3) bad password table: in SP_mode password authentification process, generate automatically, when the password authentification mistake of ONU, the sequence number of this ONU is put into the password password table, activate unsuccessful.It only is used for SP_mode.
In three kinds of registration mode under poll pattern, NA_mode only uses blacklist; SN_mode uses blacklist and white list; SP_mode uses white list, blacklist and bad password table.The shared blacklist of these three kinds of registration mode.
Registration process of the present invention is as follows:
When registration process began, OLT at first obtained new ONU sequence number, and when access module was Quiet_mode, new ONU sequence number was informed OLT by administrative staff; When access module is Polling_mode, OLT obtains new ONU sequence number automatically, and OLT is to all ONU broadcast sequence request messages, after the ONU that is in serial-number-state receives serial number request, to the OLT response message that transmits Sequence Number, thereby OLT obtains the sequence number of new ONU.OLT measures balanced time delay for each newfound ONU then, i.e. range finding.The balanced time delay that last OLT will measure sends ONU to, delays during ONU acquisition oneself balanced, has promptly set up the uplink and downlink communication passage.
ONU registration overall procedure before system brings into operation, needs access module, registration mode and the important parameter etc. of configuration-system as shown in Figure 1, if not configuration can Use Defaults.Default value can be configured to visi_mode=1, auth_mode=1, cycle=O, interval=5s, max_discover=10.
When access module is Quiet_mode, the registration operation of ONU is finished by hand by administrative staff.Administrative staff need be known new ONU sequence number in advance, will wait to operate the ONU sequence number then and inform OLT, and make OLT that this ONU is carried out corresponding operating, and its bottom operation is realized by the PON chip.
When access module was Polling_mode, at first OLT found new ONU automatically, and with newfound ONU writing sequence number table of discovery; OLT uses the control corresponding table that the sequence number table of discovery is filtered according to the registration mode of system configuration then, and activates and filter the ONU that passes through.So far, one take turns the registration operating process finish.Next judge the value of parameter c ycle, if cycle equals zero, the expression Infinite Cyclic, after waiting for a period of time, the operation of beginning next round.If cycle is not equal to zero, whether then judge cycle greater than one, this moment, cycle moved according to actual count, when cycle greater than for the moment, the wheel number of expression registration process operation does not use up as yet, and cycle value is subtracted one, waits pending next round to operate again; If cycle is non-greater than one, the wheel number of expression registration process operation uses up, and the GPON system enters Quiet_mode automatically.
(1) Quiet_mode registration process
When system configuration is Quiet_mode, under this pattern, all registration operations are finished by manual.When ONU was activated, administrative staff informed OLT with the ONU sequence number, and made OLT that this ONU is carried out activation manipulation, and OLT to this ONU range finding, finishes the activation of this ONU automatically; During to the ONU deexcitation, administrative staff inform OLT with the ONU sequence number, and make OLT that this ONU is carried out deactivating operation, and OLT sends Deactive_ONU-ID message automatically to this ONU deexcitation.When ONU was gone to enable, administrative staff informed OLT with the ONU sequence number, and made OLT that this ONU is gone enable operation, and OLT sends the laser that the Disable_serial_number message that has " Disable " option is closed this ONU automatically; When ONU was enabled, administrative staff informed OLT with the ONU sequence number, and made OLT that this ONU is carried out enable operation, and OLT sends the laser that the Disable_serial_number message that has " Enable " option is opened this ONU automatically.
(2) Polling_mode registration process:
Under Polling_mode, the ONU registration process was finished by two steps.
(1) upgrade the sequence number table of discovery:
As shown in Figure 2, the initial value of configuration disc_num is zero, disc_num represents the current into number of members of sequence number table of discovery that added, whenever in the sequence number table of discovery, insert a member, disc_num just adds one, when disc_num reached the sequence number table of discovery degree of depth (max_discover), OLT is receive sequence number response message no longer just.OLT receives the sequence number response message of ONU, if receive time-out, expression has not had ONU sequence number response message and can receive, and needn't continue to add the member in the sequence number table of discovery.The ageing time of all members in the sequence number table of discovery is added one, and reject the ONU sequence number that has reached ageing time, upgrade sequence number table of discovery process and finish; If OLT receives the sequence number response message of ONU, extract the sequence number in the message, whether check number of members that epicycle added sequence number table of discovery into less than max_discover, if not less than, then can not continue again in the sequence number table of discovery, to add the member.The ageing time of all members in the sequence number table of discovery is added one, and reject the ONU sequence number that has reached ageing time, upgrade sequence number table of discovery process and finish; If less than, then carry out follow-up operation.Next judge that this sequence number whether in blacklist, if in blacklist, then goes to enable to this ONU, and receives next bar sequence number response message.If sequence number is not in blacklist, reexamine this sequence number whether Already in the sequence number table of discovery, for the sequence number in the sequence number table of discovery, with its ageing time zero clearing in the sequence number table of discovery, whether the sequence number of judging this ONU again is in the activation table.If the sequence number of this ONU not in table of discovery, judges directly then that it is whether in the activation table.If this sequence number represents that this ONU is activated in activating table, do not need to activate again, continue to receive next bar sequence number response message.Finally, the sequence number in the activation table just can not be written in the sequence number table of discovery, and disc_num is added one.So far, a new ONU sequence number is by in the successful writing sequence number table of discovery, continue to receive next bar sequence number response message, begin next cyclic process, do not receive up to OLT and just jump out circulation when sequence number response message or disc_num equal max_discover.
(2) activation:
After upgrading the sequence number table of discovery, use the control corresponding table that the ONU in the sequence number table of discovery is filtered.Find range to filtering the ONU that passes through then, behind the ONU ranging success, this ONU sequence number is added ONU activate in the table.ONU of every activation then adds ONU with it and activates in the table, and active_num is added one.Active_num represents the number of members in the current activation table, because the ONU limited amount that OLT can activate when active_num reaches the activation table degree of depth (max_onu), finishes activation, even also have the member to be untreated in the sequence number table of discovery.
This patent has proposed three kinds of registration mode, the existing implementation procedure of describing them respectively in detail.
NA_mode: after upgrading the sequence number table of discovery, enter ONU activation, realization flow as shown in Figure 3.Number of members disc_num in the statistics current sequence number table of discovery.The initial value of configuration n is zero, and (n represents the sequence number table of discovery number of members that epicycle has been visited, and member of every visit just adds one with n, as n during greater than disc_num, represents that the member in the sequence number table of discovery has visited.), first member in the access sequence table of discovery, and n added one.Whether judge n greater than disc_num, visited, finish activation if n, represents the sequence number table of discovery greater than disc_num; If n is non-greater than disc_num, judge that then whether active_num (current activation table number of members) is less than activating the table degree of depth (max_onu), if not less than max_onu, then finish activation; If less than, then this ONU is found range.Behind the ranging success, the sequence number of this ONU is added in the activation table, and active_num is added one, and from the sequence number table of discovery sequence number of this ONU of deletion.Begin the next member in the access sequence table of discovery then.
SN_mode: realization flow as shown in Figure 4.Its implementation procedure and NA_mode are closely similar.The initial value of configuration n is zero, and n represents the sequence number table of discovery number of members that epicycle has been visited, and member of every visit just adds one with n, as n during greater than disc_num, represents that the member in the sequence number table of discovery has visited.First member in the access sequence table of discovery, and n added 1.Whether judge n greater than disc_num, visited, finish activation if n, represents the sequence number table of discovery greater than disc_num; If n is non-greater than disc_num, judge that then whether active_num (current activation table number of members) is less than activating the table degree of depth (max_onu), if not less than max_onu, then finish activation; If less than, judge that then this ONU sequence number whether in white list, if not in white list, then deletes this sequence number, and select next member in the sequence number table of discovery from table of discovery; If in white list, then this ONU is found range.Behind the ranging success, the sequence number of this ONU is added in the activation table, and active_num is added one, and from the sequence number table of discovery sequence number of this ONU of deletion.Begin the next member in the access sequence table of discovery then.
SP_mode: this pattern uses sequence number and password that ONU is verified.After OLT found range to ONU, OLT sent password request message to this ONU, to confirm the legitimacy of this ONU.OLT has this face of land of all ONU passwords that link to each other with it of record, and OLT compares password in the ONU password response message of receiving and the record in this face of land, mates then password authentification and passes through, and this ONU is legal, sends Ranging_Time message to this ONU.When password authentification is not passed through, in the sequence number adding bad password table with this ONU, after this ONU sequence number is worn out, just allow to carry out once more activation manipulation in the bad password table.
Realization flow as shown in Figure 5.In the implementation procedure of SP_mode, the initial value that at first disposes i is zero, and i represents the bad password table number of members that epicycle has been visited, member of every visit, just i is added one, as i during greater than badpas_num (bad password table number of members), the member in the expression bad password table has visited.The initial value of configuration n is zero, and n represents the sequence number table of discovery number of members that epicycle has been visited, and member of every visit just adds one with n, as n during greater than disc_num (sequence number table of discovery number of members), represents that the member in the sequence number table of discovery has visited.Earlier the bad password table is upgraded, select first member in the bad password table, and i is added one, whether judge i then greater than badpas_num, if greater than, represent then that the bad password table upgrades to finish, begin ONU sequence number in the table of discovery is filtered; If not greater than, then the ageing time with this member adds one, judges whether this member has reached ageing time again, if reach, then rejects this ONU sequence number from the bad password table, visits again the next member in the bad password table.The bad password table then begins ONU in the sequence number table of discovery is filtered after upgrading and finishing.
Select first member in the sequence number table of discovery, and n is added one, whether judge n, visited, finish activation if n, represents the sequence number table of discovery greater than disc_num greater than disc_num; If n is non-greater than disc_num, judge that then whether active_num (current activation table number of members) is less than activating the table degree of depth (max_onu), if not less than max_onu, then finish activation; If less than, then carry out following operation.Judge that this ONU sequence number whether in white list, if not in white list, then deletes this sequence number, and select next member in the sequence number table of discovery from table of discovery; If in white list, judge next that then this sequence number whether in the bad password table, if in the bad password table, then deletes this sequence number, and select next member in the sequence number table of discovery from table of discovery; Otherwise this sequence number filters and passes through, and this ONU is found range.After the range finding, carry out password authentification, the ONU that passes through to checking sends Ranging_Time message, and ONU activates successfully after receiving range finding message, and in the sequence number adding activation table with ONU, active_num adds one, and deletes from the sequence number table of discovery.The ONU of authentication failed adds in the bad password table, and deletes from the sequence number table of discovery, then begins next ONU in the sequence number table of discovery is operated.
Under Polling_mode, administrative staff can control the state of ONU by editor's control table.When ONU is activated, the sequence number of ONU is added in the white list, OLT activates this ONU automatically by above-mentioned flow process; During to the ONU deexcitation, the sequence number of ONU is deleted from white list, OLT sends Deactive_ONU-ID message automatically to this ONU deexcitation.When ONU is gone to enable, the sequence number of ONU is added in the blacklist, OLT sends the laser that the Disable_serial_number message that has " Disable " option is closed this ONU automatically; When ONU is enabled, the sequence number of ONU is deleted from blacklist, OLT sends the laser that the Disable_serial_number message that has " Enable " option is opened this ONU automatically.
When OLT detected single ONU chain rupture, OLT deleted the sequence number of this ONU automatically from activation table and sequence number table of discovery.
