Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Fig. 1 is WDM-PON system configuration schematic diagram, and as shown in Figure 1, WDM-PON is comprised of OLT, ODN, ONU tri-parts, and OLT is by one group of colored light module array, AWG(array waveguide grating), Switching Module and a plurality of local side optical module form.ONU is comprised of far-end optical module and Switching Module.The optical module of OLT and ONU is for realizing the foundation of physics photosphere passage.In the Optical Distribution Network of wavelength division multiplexing, after ONU incoming fiber optic, can only receive the downlink optical signal of specific wavelength, the far-end optical module of ONU can lock downstream wavelength, and according to downstream wavelength, be tuned to the emission wavelength of corresponding up light.After ONU modulation is correct, OLT can receive the light signal that ONU sends, and photosphere physical channel can be successfully established.The exchange chip of OLT and ONU is for realizing the forwarding of converging of the negotiation of link layer passage and data service.After physical channel is set up, the Switching Module port of interconnection will detect Link State, and consult transmission rate.After link layer negotiation completes, between OLT and ONU, can realize the intercommunication of Ethernet data business.
Based on said system Organization Chart, as shown in 2, embodiments of the invention provide a kind of real-time detection management method of ONU in WDM-PON system, and it comprises the following steps:
First, in WDM-PON system, OLT is with ONU after being connected physical layer optical channel, and the message information automatic Modulation that ONU issues according to OLT, to correct wavelength, is successfully set up the physical layer optical channel link between OLT and ONU;
Then, the physical layer optical channel Link State of each wavelength of optical line terminal (OLT) periodic polling, and complete discovery to ONU, register and fall registration management according to Link State.
When optical channel link corresponding to current detection wavelength is opening, under described wavelength, whether existing light user node (ONU) is registered in judgement, if, described optical line terminal (OLT) is initiated the state that heartbeat handling process detects light user node (ONU) under described wavelength, triggers light user node (ONU) and fall location registration process flow process after the heartbeat response message that does not receive described smooth user node (ONU); If not, at described optical channel link, keep a Preset Time to stablize the location registration process flow process that triggers light user node (ONU) under described wavelength constant in the situation that.This step contributes to find new unregistered smooth user node (ONU), and completes registration.
When optical channel link corresponding to current detection wavelength is closed condition, under described wavelength, whether existing light user node (ONU) is registered in judgement, if so, at described optical channel link, keep a Preset Time to stablize triggering light user node (ONU) constant in the situation that falling location registration process flow process.
Finally, after triggering the location registration process flow process of light user node (ONU) under described wavelength, trigger the authorisation process flow process of described optical line terminal (OLT) to the light user node (ONU) of new registration.The object of this step is to carry out authorisation process for the light user node (ONU) of new registration.
More than by the physical layer optical channel Link State of each wavelength of optical line terminal (OLT) periodic polling, detect the ONU that wavelength is corresponding whether online, thereby trigger the registration of ONU/fall register flow path; And then by triggering authorization flow, the ONU of new registration is carried out to authorisation process, effectively the ONU of access network is carried out to control and management.
According to Fig. 1, in WDM-PON system, under each wavelength, only may access 1 ONU, so OLT is by detecting the port Link State of Switching Module, can judges under this wavelength, whether there is ONU.Specifically with reference to the accompanying drawings 2, illustrate optimum embodiment of the present invention.
After the physical layer optical channel Link State of each wavelength of optical line terminal (OLT) periodic polling, carry out following steps:
Step 200: the physical layer optical channel Link State that starts n wavelength detects,
Step 300: the link circuit condition that obtains the OLT Switching Module port that current detection wavelength is corresponding; Link circuit condition by optical line terminal (OLT) Switching Module port corresponding to each wavelength of poll judges the physical layer optical channel Link State that wavelength is corresponding, if optical line terminal (OLT) Switching Module port has light user node (ONU) access, corresponding described Switching Module port negotiation is for opening, and the optical channel link that current detection wavelength is corresponding is opening; Otherwise corresponding described Switching Module port negotiation is for closing, the optical channel link that current detection wavelength is corresponding is closed condition.
Step 400: according to the link circuit condition of OLT Switching Module port, optical channel Link State corresponding to judgement current detection wavelength; When state is unlatching, execution step 412-419; When state is when closing, execution step 421-424;
Step 500: current wavelength detects complete, detects the optical channel Link State that next wavelength is corresponding, repeating step 200-500.
Step 412: the login state that obtains ONU under current detection wavelength; For authorized ONU, conventionally in the registration table of OLT, can register the information of whether registering ONU under this wavelength,
Step 413: judge under current wavelength and whether have ONU to register; If not, execution step 415, if so, performs step 416,418 successively;
Step 415: judge whether optical channel link keeps a Preset Time to stablize constant, this Preset Time can be set as 50 milliseconds; If so, representing has unregistered ONU under current detection wavelength, performs step 417: the location registration process flow process that triggers light user node (ONU); If not, perform step 500;
Step 416: optical line terminal (OLT) is initiated the state that heartbeat handling process detects light user node (ONU) under described wavelength.The heartbeat handling process here refers to OLT and initiatively to ONU, initiates heartbeat request message.
Step 418: the heartbeat response message that judges whether to receive described smooth user node (ONU); If so, represent the not middle connection breaking of ONU, execution step 500; If not, represent the middle connection breaking of ONU, trigger light user node (ONU) and fall location registration process flow process, then perform step 500.
Step 421: the login state that obtains ONU under current detection wavelength; For authorized ONU, conventionally in the registration table of OLT, can register the information of whether registering ONU under this wavelength,
Step 422: judge under current detection wavelength, whether existing light user node (ONU) is registered, and if it is performs step 423; If not, perform step 500;
Step 423: judge whether optical channel link that current detection wavelength is corresponding keeps a Preset Time to stablize constant, if so, perform step 424: trigger light user node (ONU) and fall location registration process flow process, then perform step 500; If not, directly perform step 500.
In said process, the message format of heartbeat request and heartbeat response message message, they are the same with logon message, are also the form encapsulation that adopts Ethernet OAM, as shown in table 1 below, but by different leaf fields, distinguish type of message in OAM frame head.Heartbeat response message message, by be packaged with the actual value of nominal value and the descending reception wavelength of up emission wavelength in payload, provides real-time wavelength information to OLT, realizes the wavelength function of monitoring in real time.At OLT, initiatively initiate after heartbeat request message, by heartbeat message, realize the function of wavelength monitor simultaneously.Wavelength monitor can be divided into downstream wavelength monitoring and two parts of up wavelength monitor: during (1) monitoring downstream wavelength, OLT initiatively sends heartbeat request message to ONU, ONU receives after heartbeat request, from far-end optical module, read the actual value of the descending optical wavelength receiving, and send it to OLT by heartbeat response message message, OLT contrasts descending actual wavelength and nominal wavelength in response message, judges whether downstream wavelength drifts about; (2) while monitoring up wavelength, ONU sends to OLT by heartbeat response message message by the nominal value of up transmission optical wavelength, OLT gets the actual wavelength that reads the up light receiving from local side optical module, and the up nominal wavelength in itself and heartbeat response message is contrasted, judge whether up wavelength drifts about.The ONU here can add information such as receiving wavelength, hardware resource utilization in heartbeat response message message, for OLT, obtains in time corresponding management information.
As shown in Figure 3, the location registration process flow process of above-mentioned smooth user node (ONU) comprises the following steps:
Step 600: optical line terminal (OLT) sends registration request message to the optical channel link under current detection wavelength, and the registration request message here comprises the wavelength information of described smooth user node (ONU) place optical channel link; At ONU, receive after this registration request message, ONU can record this wavelength information, when being used in operation maintenance, this wavelength information locates the residing position of ONU, or as standard wave length's reference value, be used for judging whether actual wavelength drifts about, ONU can respond and produce registration response message this message simultaneously, can add the physics indications of oneself in the registration response message producing, and uses so that OLT obtains the physics indications of ONU.
Step 601: optical line terminal (OLT) judges whether to receive the registration response message from light user node (ONU) in default time-out time, described message comprises the physics indications of described smooth user node (ONU),
If receive described registration response message, carry out following steps 602: if do not receive described registration response message, perform step successively 603 and 604;
Step 602: optical line terminal (OLT) records the physics indications of described smooth user node (ONU), and described smooth user node (ONU) is added to registration table, with existing light user node (ONU) registration under the optical channel port of wavelength described in tense marker;
Step 603: if do not receive described registration response message, described optical line terminal (OLT) will repeat to send described registration request message,
Step 604: judge whether to receive described registration response message in default repetition time or preset times; If so, perform step 602; If otherwise judge described smooth user node (ONU) registration failure.
In said process, network system, by anti-link concussion treatment mechanism, confirms that optical channel link is after stablizing opening, triggers ONU location registration process flow process.OLT sends registration request message to this wavelength port, includes the information of wavelength in message.ONU receives after message, the own residing wavelength of record.And by response registration request, report the physical identifier of oneself.If OLT receives the registration response that ONU replys in time-out time, think and succeed in registration.OLT records ONU physical identifier, and the ONU that will newly reach the standard grade adds registration table, with existing ONU registration under this wavelength port of tense marker.If do not receive the registration response that ONU sends in time-out time, OLT will repeat to send registration request message, if still without response, think and will continue the port status under other wavelength of inquiry by registration failure.
The message format of above-mentioned registration request and registration response message adopts the mode of following table 2:
They adopt the form encapsulation of Ethernet OAM, and only the physical link between OLT and ONU forwards, must physical identifier (SN) and up-downgoing wavelength information for transmitting WDM-PON ONU registration institute.
As shown in Figure 4, above-mentioned authorisation process flow process comprises the following steps:
Step 700: optical line terminal (OLT) judges whether the optical channel link port that described current detection wavelength is corresponding opens stream filtering function, defines the access rule having with described smooth user node (ONU) in described stream filtering function; If so, perform step successively 702 and 703, if not, after execution step 701, perform step successively 702 and 703;
Step 701: open described stream filtering function;
Step 702: resolve the packet from described smooth user node (ONU) that described optical channel link port receives,
Step 703: judge that whether described packet meets described access rule, if so, performs step 705; If not, perform step 704;
Step 704: abandon the frame data except log-in protocol message in described packet;
Step 705: authorize by described packet, and close described stream filtering function.
The object that increases by 700 judgements in above step is to reduce mistake, and it is effective to make to operate.In this process, OLT is the stream filtering function based on ad hoc rules at port open corresponding to each wavelength: in to white list, do not exist, can not authorize the ONU passing through, its corresponding wavelength passage ACL(Access Control List (ACL)) rule abandons all Frames except log-in protocol frame for filtering; To existing in white list, can authorizing the ONU passing through, its corresponding wavelength pathway closure filtering rule is for allowing all data normally to forward.The white list here refers to the ONU that meets above-mentioned access rule.And the access rule here can be the ACL(Access Control List (ACL) that comprises target MAC (Media Access Control) address and ethernet type).Such as OLT Switching Module can define target MAC (Media Access Control) address, be 01:80:c2:00:00:02, the ACL access rule that ethernet type is 0x8809.Under the undelegated state of ONU, acl rule is applied to the Switching Module port of this wavelength, if the bag that port is received does not meet acl rule, will it be abandoned and will not be forwarded.The message that only meets acl rule just allows to pass through.Under the state of authorizing at ONU, acl rule will be cancelled, and all entry port bags can normally forward.
Above-mentionedly fall location registration process flow process and comprise the following steps:
First, optical line terminal (OLT) is deleted user node (ONU) log-on message corresponding to current detection wavelength described in registration table;
Then, optical line terminal (OLT) is opened stream filtering function in optical channel link port corresponding to described current detection wavelength, defines the access rule having with described smooth user node (ONU) in described stream filtering function.
The said method flow process all operation based on optical line terminal (OLT) is controlled, so said method is implanted in and carries out a kind of new optical line terminal (OLT) equipment in optical line terminal (OLT) equipment by software programming, comprise Switching Module and for recording light user node (ONU), authorize the registry hive of log-on message, it also comprises:
