Description

The method and system of user port VLAN traffic management are realized in optical network unit

Technical field

The present invention relates to PON (Passive Optical Network, passive optical-fiber network) ONU (Optical Network Unit, optical network unit) Layer 2 data stream VLAN tag in system (Virtual Local Area Network, VLAN) processing function realization, the Layer 2 data stream VLAN tag processing function refers in ONU systems, and it is counted Decide whether to carry out user's up-downgoing message VLAN tag processing according to stream engine, ONU VLAN tags process object includes IEEE CVLAN (the Customer that (Institute of Electrical and Electronics Engineers) 802.1Q is defined VLAN, user private network VLAN tag) and IEEE 802.1ad QinQ (also referred to as Stacked VLAN or Double VLAN, refer to User private network VLAN tag is encapsulated in runner public-network VLAN tag) introduce SVLAN (Service Provider VLAN, runner public-network VLAN tag).

Background technology

At present, PON ONU include EPON (Ethernet Passive Optical Network, ethernet passive optical network) With GPON (Gigabit-Capable Passive Optical Network, gigabit passive optical network).Based on gigabit ether The EPON system of fidonetFido is a kind of novel optical fiber access network technology defined by IEEE802.3, and it uses point-to-multipoint group Web frame, with the features such as transmission bandwidth is high, autgmentability is strong, can provide multiple business on Ethernet.GPON technologies are EPON broadband access standard based on ITU-TG.984.x standards, is considered as realization by domestic and international most of operators at present High bandwidth, diversification access the desirable technique of network service, compared with EPON, and GPON is in line speed, bandwidth availability ratio, maximum point Certain advantage is taken in terms of light when operation management.

PON system is by the optical line terminal OLT (Optical Line Terminal) of local side, the optical-fiber network list of user terminal First ONU (Optical Network Unit) and Optical Distribution Network ODN (Optical Distribution Network) compositions, As shown in Figure 1.

CSMA/CD (visit by Carrier Sense Multiple Access/Collision Detect, collision sense multiple Ask/collision detection) mechanism can ensure the normal communication of Ethernet data network, nonetheless, when the number of host in network reaches To not only forwarding performance can drastically decline during certain amount, and it can bring net can be directly resulted under broadcast storm, extreme case Network is paralysed.Conventional switch can only split collision domain, although realizing that LAN interconnections can solve conflict using such switching equipment (Collision) serious the problem of, but still broadcasting packet can not be isolated, this is that the main cause for needing VLAN splits broadcast Domain.IEEE 802.1Q vlan technologys can be divided into an actual LAN LAN --- the VLAN, each VLAN of multiple logics Constitute a broadcast domain, can be communicated between the main frame in VLAN, and the main frame between VLAN then can not directly intercommunication, therefore, extensively Text is reported to be limited in a VLAN.Optical network unit is operated in the data link layer of OSI network model, the equipment one of early stage As can only identification data link layer packaging form (some current chip solutions can recognize that more than data link layer content), because This, VLAN tag also can only be just added in the encapsulation format of data link layer.IEEE802.1Q defines addition VLAN tag Ethernet frame format afterwards, is shown in Fig. 2.

4094 VLAN at most can be used using 12 bit bit identification VLAN ID values, i.e. network in IEEE802.1Q specifications ID values (0 and 4095 are used as reservation protocol fields).With the development of Metropolitan Area Network (MAN), VLAN resources day are becoming tight, and network needs more VLAN resource isolation users, this is to need the basic reason of QinQ technologies.The QinQ technologies that IEEE 802.1ad are defined are in bag The packet outer layer of the VLAN tag containing 802.1Q encapsulates one layer of VLAN tag, its content and IEEE802.1Q VLAN tags one again Cause, so that workable VLAN resources reach 4094 × 4094 in whole network, and operator can advise according to respective demand Draw Local Area Network VLAN tag and message passes through the VLAN tag of Metropolitan Area Network (MAN) carrying.Optical network unit can be handled simultaneously mostly at present IEEE802.1Q VLAN tags and IEEE 802.1ad VLAN tags, some schemes can also individually change they VLAN ID, Ethernet frame format after Priority, TPID value, insertion IEEE 802.1ad VLAN tags is shown in Fig. 3.

In optical network unit (hereinafter referred to as ONU), in order to reach that user isolation, service area are graded purpose, generally in ONU User port configure a plurality of VLAN traffic, these business are potentially included (by taking uplink service as an example)：Marked to up without VLAN The message increase private network VLAN tag of label, transparent transmission carry and specify the message of private network VLAN tag, specify private network to carrying The message of VLAN tag adds one layer of outside VLAN label etc. again.Realize that the method for VLAN traffic is main in ONU equipment at present Have：Exist based on ONU exchange chips (SWITCH), based on ONU PON chips, with reference to exchange chip and the respective advantage of PON chips The establishment of VLAN traffic stream is realized in ONU equipment by software program, specifically webmastering software issues configuration, and equipment first deletes core The old configuration of piece, then configure chip for every new business；This method receives the user port VLAN traffic that webmaster issues and matched somebody with somebody every time Put, the old service configuration data locally preserved according to software first removes chip association attributes, be not relevant for webmastering software under this Associating between sending service and last time issuing service, to each new business again assignment chip register.

At present, above-mentioned network management system carries out configuration and builds management method entirely using typical delete entirely, i.e., receive new industry every time Business configuration, software is first deleted old configuration revival and newly configured, and the number of times of operation bidirectional hardware table item can be so added, when serious Can also user traffic flow be caused to interrupt.In addition, many counting methods are bound too closely with particular hardware form, after scheme change, no It is easy to software transplanting, it has not been convenient to update, so that the business configuration state of user port can not be tracked effectively.

So problem above has to be solved.

The content of the invention

The technical problems to be solved by the invention are：Use and typically delete entirely for current most VLAN traffic management methods Situation hair complete to build management method to have aggravated the number of times that system operates hardware table item, that user traffic flow may be caused to interrupt It is raw, and can not effectively track the business configuration state of user port.

In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is to provide in a kind of optical network unit and realized The method and system of user port VLAN traffic management.

The method that the management of user port VLAN traffic is realized in such scheme, in optical network unit, it includes following step Suddenly：

The corresponding VLAN traffic configuration data attribute list of each user port is set up, for each VLAN of the book of final entry The number of operations of the corresponding VLAN traffic configuration data of business and each class VLAN traffic, according to the VLAN traffic configuration data Attribute list is in related service hardware and is operated in logic, and preserves the VLAN traffic in ONU the first memory space Configuration data attribute list, ONU carries out existing VLAN traffic in the VLAN traffic configuration data attribute list, and real-time update institute State corresponding VLAN traffic number of operations in VLAN traffic configuration data attribute list；

According to the VLAN traffic configuration data issued from gateway of reception, form portion and meet the VLAN traffic configuration In the new form of data attribute list statistical rules, and the second memory space being stored in ONU, relatively more described first memory space With the list data in the second memory space, the new form and VLAN traffic configuration number in first memory space are marked According to the inconsistent VLAN configuration datas of attribute list, comparative result is used as；

Update described in related service hardware and logic, and first memory space according to the comparative result VLAN traffic configuration data attribute list, come into force business configuration.

In such scheme, the corresponding VLAN traffic configuration data of each class type of service includes private network tags, private network mark Sign the private network tags after operator scheme, switching, public network label and enable mark, public network VLAN tag, TLS (Transparent LAN Services, transparent Ethernet) VLAN tag enable mark and TLS VLAN tags.

In such scheme, the VLAN traffic configuration data attribute list includes：For recording each class type of service pair The business grouped data table TST for the VLAN traffic configuration data answered, the business for every new VLAN traffic type of the book of final entry Type list STT and the service counting table SCT for recording each class VLAN traffic number of operations, type of service table STT numbering are simultaneously The type of service title of business in statistic record business grouped data table TST, service counting table SCT corresponding record type of service tables The number of operations of each class VLAN traffic in STT, is renamed after STT and SCT tables locally preserve.

In such scheme, ONU carries out existing VLAN traffic in the VLAN traffic configuration data attribute list, and in real time The step of updating corresponding VLAN traffic number of operations in the VLAN traffic configuration data attribute list is as follows,

Step 201, STT the and STC tables preserved after last time configuration successful are copied in the respective table locally preserved；

Step 202, to each VLAN traffic of the port, circulation terminates；

Step 203, whether the big type of service for judging VLAN is unicastIf it is, performing step 204；Otherwise, then hold Row step 205；

Step 204：Separating unicast type of service；

Step 205：Distinguish multicast service type；

Step 206：Preserve type and count up to STT and STC tables；

Step 205：To each VLAN traffic of the port, circulation terminates.

In such scheme, the differentiation flow of the unicast service type is as follows：

Step 214, separating unicast type of service entrance；

Step 224, judge whether attribute 5 in business grouped data table TST " TLS VLAN tags enable mark " is " to make Can ", if it is, showing that the business is unicast TLS business (" type 8 "), otherwise perform step 234；

Step 234, it is necessary to further check whether attribute 2 " private network VLAN tag operator scheme " is pattern 1, the attribute with The judgement of other types of service is all relevant.Judge attribute 2 " private network VLAN tag operator scheme " for " pattern 1 " then shows the industry Business private network VLAN patterns meet " Class1 " and " type 2 " is defined, and performs step 244；If " private network VLAN tag is operated attribute 2 Pattern " is not pattern 1, then performs step 254；

Step 244, judge that public network VLAN tag is enabled to mark whether as " enable ", if public network VLAN tag enables mark During for " enable ", then type of service is unicast TAG＆QinQ business, is otherwise unicast TAG business.

Step 254, it is separating unicast TRANSPRENT business and unicast ALL TRANSPARENT business, while not extra Increase date transfer on network, judge whether attribute 3 " private network VLAN tag operator scheme " is " 0xffff " in this step, when CVLAN label VLAN ID value 0xffff, then be labeled as unicast ALL TRANSPARENT business (" types by type of service 7 "), if the VLAN tag VLAN non-zero xffff of ID values, step 264 is performed；

Step 264, judge whether " private network VLAN tag operator scheme " is pattern 3, if so, then performing step 274, otherwise Perform step 284；

Step 274, judge whether " public network VLAN tag enables mark " is enable, if so, being then labeled as unicast TRANSLATION＆QinQ business, otherwise labeled as unicast TRANSLATION business；

Step 284, judge whether " public network VLAN tag enables mark " is enable, if so, being then labeled as unicast TRANSPARENT＆QinQ business, otherwise labeled as unicast TRANSPARENT business；

Pattern 1：Up addition private network VLAN tag and descending stripping；

Class1：That is unicast TAG business, when referring to that the up message for not carrying VLAN tag flows through ONU, ONU is its addition One layer of private network VLAN tag；When the descending message for carrying the private network VLAN tag flows through ONU, ONU first peels off the VLAN tag, so Rear line port is forwarded；

Type 2：That is unicast TAG＆QinQ business, when referring to that the up message for not carrying VLAN tag flows through ONU, ONU is While it adds private network VLAN tag, public network VLAN tag is added in its outer layer；More than descending carrying two layers VLAN tag When message flows through ONU, ONU first peels off two layers of VLAN tag, is then forwarded to user port；

Pattern 3：Up-downgoing symmetrically switches the message VLAN tag for carrying and specifying private network VLAN tag；

Unicast TRANSPARENT business：When referring to that the up message for carrying specified private network VLAN tag flows through ONU, ONU is saturating Bright transmission message；The descending message for carrying the private network VLAN tag is when flowing through ONU, ONU equally realize transparent transmission and to Family port is forwarded；

Unicast ALL TRANSPARENT business：ONU does not perceive private network VLAN tag and public network VLAN tag, realizes all The transparent transmission of message；

Unicast TRANSLATION＆QinQ business：When referring to that the up message for carrying specified private network VLAN tag flows through ONU, While ONU switches private network VLAN tag, public network VLAN tag is added in its outer layer；More than descending carrying two layers VLAN tag When message flows through ONU, ONU first peels off public network VLAN tag, private network VLAN tag then is switched back into former VLAN tag, again finally Forwarded to user port；

Unicast TRANSLATION business：When the up message for carrying specified private network VLAN tag flows through ONU, ONU switchings are private Net VLAN tag；When the descending message for carrying private network VLAN tag after switching flows through ONU, ONU first switches back into the VLAN tag Former VLAN tag, is then forwarded to user port；

Unicast TRANSPARENT＆QinQ business：When the up message for carrying specified private network VLAN tag flows through ONU, ONU Public network VLAN tag is added in its outer layer；When more than descending carrying the message of two layers of VLAN tag flows through ONU, ONU first peels off outer Layer public network VLAN tag, is then forwarded to user port.

In such scheme, the differentiation flow of the multicast service type is as follows：

Step 215, multicast service type entrance is distinguished；

Step 225, judge whether " private network VLAN tag operator scheme " is pattern 3, if it is, labeled as multicast TRANSLATION business；Step 235 is performed if not；

Step 235, judge whether " private network VLAN tag operator scheme " is pattern, if it is, labeled as multicast TRANSPARENT business, otherwise labeled as multicast TAG business；

Pattern 2：Up-downgoing carries the message transparent transmission for specifying private network VLAN tag；

Pattern 3：Up-downgoing symmetrically switches the message VLAN tag for carrying and specifying private network VLAN tag；

Multicast TRANSLATION business：When the downlink message for carrying specified private network VLAN tag flows through ONU, ONU first switches Private network VLAN tag, is then forwarded to user port；

Multicast TRANSPARENT business：When the downlink message for carrying specified private network VLAN tag flows through ONU, ONU realizes report Literary transparent transmission is simultaneously forwarded to user port.

In such scheme, during the acquisition of the comparative result, charting is every in second memory space The number of operations of one class VLAN traffic is the operation time of each class VLAN traffic of charting in N, first memory space Number is SERVICE_NUM；Compare the number of operations of every VLAN traffic of list data in two memory spaces one by one, work as N=0 And during SERVICE_NUM=0, directly return successfully, represent consistent with current business, it is not necessary to reconfigure, the business is related Be locally configured data keep it is constant；Work as N>During 0 and SERVICE_NUM=0, all new business need to reconfigure, and represent to work as The VLAN traffic of preceding comparison is new business, and the business is not included in current business, now needs to be locally configured for the traffic assignments Shelf space, record traffic related configuration data, and operate related hardware list item；As N=0 and SERVICE_NUM>When 0, delete All business in old service set, represent that this is not issued, but are current business, now need to empty the corresponding institute of the business Have to be locally configured and preserve list item and the related hardware table item of the business；Work as N>0 and SERVICE_NUM>When 0, using bit mark Note mode distinguishes record traffic consensus information, if new business is consistent with current business, will the two corresponding bit set.

In such scheme, the VLAN traffic configuration data for also including issuing gateway in the process carries out port industry The global validity checking for configuration data of being engaged in, is specifically included：

Operated before each business configuration once, software receives the VLAN traffic of port with postponing, every industry of circular test Whether the parameter of business is correct effectively, and flow will be examined in whether type of service is " unicast " or " multicast ", the private network of port VLAN operator schemes whether be " pattern 1 ", " pattern 2 ", " one of pattern 3 ", private network VLAN tag value, public network VLAN tag value, Whether TLS VLAN tags value meets IEEE802.1 regulations, and public network VLAN tag enables mark, TLS VLAN tags and enables mark Whether it is " enable " or " going to enable ", each VLAN traffic inspection to the port terminates, as long as one of attribute value Mistake will return to this configuration failure；

Pattern 1：Up addition private network VLAN tag and descending stripping；

Pattern 2：Up-downgoing carries the message transparent transmission for specifying private network VLAN tag；

Pattern 3：Up-downgoing symmetrically switches the message VLAN tag for carrying and specifying private network VLAN tag.

First row record traffic type in upper table 3, it is consistent with the type of service in type of service table STT to correspond to, i.e., The type of above-mentioned 11 group VLAN traffic, or the new VLAN traffic class defined according to above-mentioned 11 group；Secondary series record traffic Type counts, the i.e. number of operations relative to each class VLAN traffic in type of service table STT, ONU carry out the type of service In table STT during existing VLAN traffic, corresponding type of service in the service counting table SCT is counted to the operation for carrying out Jia 1, For recording VLAN traffic number of operations in real time.

Certainly the invention is not restricted to be separated into three contingency table progress using by above-mentioned VLAN traffic configuration data attribute list The business configuration state of the operations such as inquiry, renewal, record, effectively tracking user port, is carried out it is also contemplated that collecting a table The operations such as inquiry, renewal, record.In a word, VLAN traffic configuration data attribute list homogeneous classification is allowed to record above-mentioned for recording 9 property values of VLAN traffic configuration data, and type of service and each class VLAN traffic type counts, it is each for counting The number of operations of class VLAN traffic can complete the foundation of whole administrative model, based on the foundation of above-mentioned administrative model, complete surplus Remaining step.

Fig. 6 is that business of the present invention is classified and counting flow chart.For each VLAN traffic, be first divided into unicast, The major class of multicast two, subtype is subdivided per major class, the classification results of i-th business are STT { i }, are i-th of list item of STT table, The type of service of STT { i } records is matched in SCT tables simultaneously, and the type of service occurrence number is added 1.As shown in fig. 6, step In rapid 200, ONU carries out existing VLAN traffic in the VLAN traffic configuration data attribute list, and VLAN described in real-time update It is as follows the step of corresponding VLAN traffic number of operations in business configuration data attribute list,

Step 201, STT the and STC tables preserved after last time configuration successful are copied in TSTT and TSTC tables, will configured Successful table is preserved to local, for more new record；

Step 202, to each VLAN traffic of the port, circulation terminates；

Step 203, whether the big type of service for judging VLAN is unicastIf it is, performing step 204；Otherwise, then hold Row step 205；

Step 204：Separating unicast type of service, divides small type of service, for recording STT table；

Step 205：Multicast service type is distinguished, small type of service is divided, for recording STT table；

Step 206：Preserve type and count up to STT and STC tables；

Step 205：To each VLAN traffic of the port, circulation terminates.

For above-mentioned separating unicast type of service and differentiation multicast service type, according to above-mentioned business grouped data table TST Attribute mark and judge, as shown in Figure 7 and Figure 8.

Fig. 7 is the determination flow of unicast service type.Since determination flow directly determining the attribute of type of service.

Step 214, separating unicast type of service entrance；

Step 224, judge whether attribute 5 in business grouped data table TST " TLS VLAN tags enable mark " is " to make Can ", if it is, showing that the business is unicast TLS business (" type 8 "), otherwise perform step 234；

Step 234, it is necessary to further check whether attribute 2 " private network VLAN tag operator scheme " is pattern 1, the attribute with The judgement of other types of service is all relevant.Judge attribute 2 " private network VLAN tag operator scheme " for " pattern 1 " then shows the industry Business private network VLAN patterns meet " Class1 " and " type 2 " is defined, and performs step 244；If " private network VLAN tag is operated attribute 2 Pattern " is not pattern 1, then performs step 254；

Step 244, judge that public network VLAN tag is enabled to mark whether as " enable ", if public network VLAN tag enables mark During for " enable ", then type of service is unicast TAG＆QinQ business, is otherwise unicast TAG business.

Step 254, it is separating unicast TRANSPRENT business and unicast ALL TRANSPARENT business, while not extra Increase date transfer on network, judge whether attribute 3 " private network VLAN tag operator scheme " is " 0xffff " in this step, when CVLAN label VLAN ID value 0xffff, then be labeled as unicast ALL TRANSPARENT business (" types by type of service 7 "), if the CVLAN VLAN non-zero xffff of ID values, step 264 is performed；

Step 264, judge whether " private network VLAN tag operator scheme " is pattern 3, if so, then performing step 274, otherwise Perform step 284；

Step 274, judge whether " public network VLAN tag enables mark " is enable, if so, then labeled as mark unicast TRANSLATION＆QinQ business, otherwise labeled as unicast TRANSLATION business；

Step 284, judge whether " public network VLAN tag enables mark " is enable, if so, being then labeled as unicast TRANSPARENT＆QinQ business, otherwise labeled as unicast TRANSPARENT business.

Above according to CVLAN operator schemes and public network VLAN enable mark can distinguish successively " type 3 ", " type 4 ", " type 5 ", " type 6 ".

Fig. 8 is the determination flow that step 205 distinguishes multicast service type.Multicast service determination flow is more directly perceived, can basis The different values of three kinds of CVLAN operator scheme attributes directly distinguish " type 9 ", " Class1 0 ", " Class1 1 ".Institute specific as follows Show：

Step 215, multicast service type entrance is distinguished；

Step 225, judge whether " private network VLAN tag operator scheme " is pattern 3, if it is, labeled as multicast TRANSLATION business；Step 235 is performed if not；

Step 235, judge whether " private network VLAN tag operator scheme " is pattern, if it is, labeled as multicast TRANSPARENT business, otherwise labeled as multicast TAG business.

Based on above-described embodiment, Fig. 9 gives business configuration in above-mentioned steps 300 and step 400 and compared and configuration take-effective Flow chart.Obtaining the detailed process of comparative result in above-mentioned comparison step 300 by marking is：

The number of operations of each class VLAN traffic of charting is N in second memory space, first storage The number of operations of each class VLAN traffic of charting is SERVICE_NUM in space；Compare one by one in two memory spaces The number of operations of every VLAN traffic of list data,

As N=0 and SERVICE_NUM=0, directly return successfully, represent consistent with current business, it is not necessary to match somebody with somebody again Put, the related data that are locally configured of the business keep constant；

Work as N>During 0 and SERVICE_NUM=0, all new business need to reconfigure, and represent the VLAN traffic currently compared For new business, the business is not included in current business, now needs that shelf space, record traffic is locally configured for the traffic assignments Related configuration data, and related hardware list item is operated, into step 12.3；

As N=0 and SERVICE_NUM>When 0, all business in old service set are deleted, represent that this is not issued, but For current business, now need to empty the corresponding all hardware lists that preservation list item and business correlation is locally configured of the business , into follow-up delete step；

Work as N>0 and SERVICE_NUM>When 0, record traffic consensus information is distinguished using bit mark mode, if newly Business is consistent with current business, by the two corresponding bit set, is specifically shown in step 12.2.

Step 12.2：Defined variable NEW_SERVICE_BITMAP and OLD_SERVICE_BITMAP, the two initial value is 0, the NEW_SERVICE_BITMAP comparative result marker bit information for recording new business, OLD_SERVICE_BITMAP is used for The comparative result marker bit information of old service is recorded, lowest bit position represents the state of the 1st article of business, the like, wherein often The number of bits that individual variable is included is not less than the single user port maximum traffic number that ONU systems allow.For each new business S { i }, if it is equal with a certain bar business TST { j } in old service set TST tables, by variable NEW_SERVICE_ BITMAP bit i is entered as 1, and variable OLD_SERVICE_BITMAP bit j is entered as into 1, represents in new business I-th business it is consistent with the configuration data of the j-th strip business in current business.After the completion of all business in S compare, divide three Step is sequentially completed：

A. the number of bits being set using in variable NEW_SERVICE_BITMAP and OLD_SERVICE_BITMAP is industry (such as NEW_SERVICE_BITMAP bit i is set business index, then it represents that 1) bit of i-th business is set, S If in business i be set, show that this configured business last time, it is not necessary to reconfigure, if the business j in TST is set, Show that the business is appeared in new business set S, therefore all configuration datas for being set business and seizure condition mark in TST Keep constant, all corresponding traffic type informations of business that are set are without change in TSTT；

B. all business being not set in TST set are deleted, it is follow-up into this paper to each business that need to be deleted Business delete step；

C. all business being not set, the new business reconfigured to each need, into step in S set are reconfigured Rapid 12.3；

Step 12.3：The new business i of configuration, reference service classification and the result of counting process are needed for each in S Table STT { i }, configures according to corresponding type of service and TST tables is traveled through after hardware resource, configuration successful, finds seizure condition for " not Take " list item after, S { i } is copied to the list item, and mode bit is changed to " to take ".In addition, also needing the corresponding tables of TSTT Item is entered as STT { i }, and to track the VLAN traffic type of user port, TSCT tables can be copied directly from SCT tables.Business is complete After the completion of portion's configuration, SERVICE_NUM is entered as N.

Business configuration is come into force in the following several ways according to bit mark in above-mentioned steps：New business and current business are same Markers clocks, it is not necessary to any operation；When new business is not labeled, new business is configured；When current business is not labeled, deletes and work as Preceding business.Step is performed according to the statement of comparative result exhaustive division, can effectively reduce the operation to control chip hardware logic.

Figure 10 is above-mentioned port vlan business configuration flow chart, after successful configuration service, all industry in new business set S Business is preserved to TST set, and TSTT have recorded the corresponding type of service of new business, and TSCT have recorded port traffic classification of type meter Number.Step 12.3 first deletes the corresponding service in TSTT set, it is therefore an objective to empty the TST list items and TSTT list items of these business, For follow-up new business preparation memory headroom.

Figure 11 is the flow chart for deleting port vlan business.The step of deleting i-th business in TST set is as follows：

Step 14.1：The type of service of this VLAN traffic is judged according to TSTT { i }, and ONU is deleted according to type of service Associated hardware resource；

Step 14.2：The configuration data of i-th business list item of TST tables is emptied, and the list item seizure condition position is changed to " account for With "；

Step 14.3：The traffic type information of i-th list item of TSTT tables is emptied, initialization type of service table TSTT is used as.

Step 14.4, business is returned to delete successfully.

As described in Figure 4, embodiments of the invention also include the VLAN traffic configuration number issued to gateway in the process According to the global validity checking step 100 for carrying out port traffic configuration data, it can accordingly be arranged on before step 200, specifically Flow is as figure 5 illustrates.After ONU equipment electrifying startup, software first initializes local service configuration relevant entries, receives under webmastering software The VLAN traffic configuration data of hair, these configuration datas are general in units of unique user port, generally comprise many of the port Bar VLAN traffic.Global validity checking subprogram checks whether every VLAN traffic configuration data is correct effectively one by one, including Private network VLAN tag value, public network VLAN tag value etc..Fig. 5 is the global legitimacy inspection of VLAN traffic configuration data of the present invention Look into functional flow diagram.IEEE802.1Q regulations VLAN ID values are made up of 12 bits, and span is as previously described.TPID is accounted for With 16 bits, 0x8100 is defaulted to.PRIORITY is 802.1P priority, takes 3 bits, value 0-7, for table Show Ethernet priority.The default values of CFI are 0.

Initial table S, STT, SCT first in Fig. 5, the action is operated once before each business configuration, and software receives end The VLAN traffic of mouth is with postponing, and whether the parameter of every business of circular test is correct effectively.Flow is examined in type of service No is " unicast " or " multicast ", and whether the private network VLAN operator schemes of port are " pattern 1 ", " pattern 2 ", " one of pattern 3 ", private Whether net VLAN tag value, public network VLAN tag value, TLS VLAN tags value meet IEEE802.1 regulations, public network VLAN tag Enable mark, TLS VLAN tags and enable and mark whether as " enables " or " go enable ", to each VLAN traffic of the port Inspection terminates, as long as one of attribute value mistake will return to this configuration failure.

As shown in Figure 10, before above-mentioned steps 300 compare the configuration data of new business and current business also include The step of " port traffic collision detection ", collision detection is carried out to all VLAN traffics of port, can prevent VLAN traffic it Between there is logic error, the catastrophe failure such as these mistakes may cause service failure, customer traffic obstructed.The mesh of collision detection Be all VLAN traffic mutual tolerances for ensureing user port, be not in expected inconsistent data flow, idiographic flow is as follows It is shown.

Figure 12 is that the conflict between the different VLAN traffics in port may situation.Conflict between VLAN traffic refers to some industry Coexisting for business can cause service logic chaotic.Business configuration process typically follows following principle (it is assumed that every business configuration data Without repetition), this principle is the universal method based on industry come fixed：

Principle 1：(unicast service is not differentiated between for one user port at most one unicast TAG business of configuration or multicast TAG business " Class1 " and " type 2 ")；

Principle 2：A user port is allowed to there is a plurality of business simultaneously, the CVLAN operator schemes of these business can be flexible Configuration, but do not allow certain two business CVLAN label (namely " private network VLAN tag operator scheme ") occur unanimously, but The inconsistent situation of CVLAN operator schemes；

Principle 3：One user port at most one unicast ALL TRANSPARENT business of configuration, and the business with it is other Unicast service is incompatible；

Principle 4：Any two unicast services of one user port, if their CVLAN labels are consistent and CVLAN is operated Pattern is consistent, does not allow the public network VLAN tag enable mark of the two inconsistent, when public network VLAN tag, which is enabled, marks consistent, Do not allow public network VLAN tag inconsistent；

Principle 5：One user port at most one unicast TLS business of configuration, and the business can not with unicast TAG business and Unicast TAG＆QinQ business coexists, if port also has CVLAN operator schemes for " pattern two " or " other unicasts of pattern three " Business, then the CVLAN labels of the business can not be consistent with TLS VLAN tags.

Run counter to any of the above-described principle to would potentially result in conflicting between business, Figure 12 lists all possible conflict feelings Condition.Illustrate herein：The CVLAN labels (namely " private network VLAN tag ") of business 1 are { VLAN ID:100,PRIORITY: 0,TPID:33024,CFI:0 }, CVLAN operator schemes are " pattern 2 "；The CVLAN labels of business 2 are consistent with business 1, CVLAN Pattern is " pattern 3 ".If two business come into force above simultaneously, when the Business Stream for carrying the VLAN ID passes through ONU, business 1 is required The transparent transmission Business Stream, business 2 requires switching CVLAN labels, it is clear that logic conflict occurs in the action of two business.

Business configuration process easily conflicts, it is therefore desirable to which rational detection method excludes all service conflicts, with reference to Above principle, collision detection includes following steps：

Step 11.1：The service counting table SCT that reference service is classified with counting process, judges type of service " multicast TAG industry Whether the operation count of business " is more than 1, the mistake of principle 1 is run counter to if so, then returning, otherwise into step 11.2.Concrete operations are illustrated Explanation, it is assumed that record above-mentioned 12 class type of service in type of service table STT successively, then corresponding service counting table SCT will successively Record the number of operations of 12 class types of service, with type of service " multicast TAG business " be 9 for index, judge STC { 9 } sign Whether type of service is counted is more than 1；

Step 11.2：The service counting table SCT that reference service is classified with counting process, judges type of service " unicast TAG industry Whether the operation count of business " is more than 1, the mistake of principle 1 is run counter to if so, then returning, otherwise into step 11.3.Concrete operations are illustrated Illustrate, it 1 is index to be with type of service " unicast TAG business ", judges that whether the type of service that STC { 1 } is characterized is counted more than 1, The mistake of principle 1 is run counter to if so, then returning, otherwise into step 11.3.

Step 11.3：For each business configuration data S { i }, by its CVLAN label and other all business CVLAN labels are compared, if S { i } and S { j } CVLAN labels are unequal, continue to compare S { i } and other business, if phase Deng, then compare S { i } and S { j } CVLAN operator schemes, when the pattern of the two is unequal, the mistake of principle 2 is run counter in return, Otherwise continue to compare S { i } and other business.If all business are completed without prejudice to principle 2 after above-mentioned inspection, into step two-by-two 11.4；

Step 11.4：The service counting table SCT that reference service is classified with counting process, judges type of service " unicast ALL Whether the operation count of TRANSPARENT business " is more than 1, is 7 to be with type of service " unicast ALL TRANSPARENT business " Index, judges whether STC { 7 } is more than 1, and the mistake of principle 3 is run counter to if so, then returning, and otherwise continues judgement business number N, when N is more than When 1, same return runs counter to the mistake of principle 3, only continues step 11.5 when N is equal to 1；

Step 11.5：For each business configuration data S { i }, if its type of service is " unicast ", by its CVLAN Label and the CVLAN labels of other all business are compared, if S { i } and S { j } CVLAN labels are unequal, continue to compare Compared with S { i } and other business, if equal, then compare S { i } and S { j } CVLAN operator schemes, when the pattern of the two is unequal When, the mistake of principle 2 is run counter in return, is otherwise continued to compare the public network VLAN enable marks of the two, is marked inconsistent or make if enabling It can mark unanimously and public network VLAN tag is inconsistent, the mistake of principle 4 is run counter in return, and other situation continueds compare S { i } and other Business.If all unicast services are completed without prejudice to principle 2, principle 4 after above-mentioned inspection, into step 11.6 two-by-two；

Step 11.6：The service counting table SCT that reference service is classified with counting process, with type of service " unicast TLS industry It 8 is index that business ", which is, judges whether STC { 8 } is more than 1, if more than 1, returning and running counter to the mistake of principle 5, otherwise respectively with type of service " unicast TAG " business " and " unicast TAG＆QinQ business " is index, judges whether STC { 1 }, STC { 2 } are more than 1, as long as wherein One is more than or equal to 1, and the mistake of principle 5, other situation continued traversal business classification and the result table of counting process are run counter in return STT, sets the index i of variable TLS_SERVICE_INDEX record unicast TLS types of service in the table, sets variable TLS_ VLAN record S { i } TLS service VLAN labels, TLS_VLAN and the CVLAN labels of other business in S are compared, these The CVLAN patterns of business all for " pattern two " or " pattern three ", if there is a situation where it is equal, return run counter to the mistake of principle 5, it is other Situation terminates this collision detection flow.

6. according to the method described in claim 1, it is characterised in that during the acquisition of the comparative result, described second deposit The number of operations of each class VLAN traffic of charting in space is stored up for N, charting is every in first memory space The number of operations of one class VLAN traffic is SERVICE_NUM；Compare every VLAN of list data in two memory spaces one by one The number of operations of business, as N=0 and SERVICE_NUM=0, directly returns successfully, represents consistent with current business, be not required to Reconfigure, the related data that are locally configured of the business keep constant；Work as N>During 0 and SERVICE_NUM=0, all new industry Business needs are reconfigured, and it is not include the business in new business, current business to represent the VLAN traffic that currently compares, is now needed Shelf space, record traffic related configuration data is locally configured for the traffic assignments, and operates related hardware list item；As N=0 and SERVICE_NUM>When 0, all business in old service set are deleted, represent that this is not issued, but be current business, now needed Empty corresponding all be locally configured of the business and preserve list item and the related hardware table item of the business；Work as N>0 and SERVICE_ NUM>When 0, record traffic consensus information is distinguished using bit mark mode, if new business is consistent with current business, by two The corresponding bit set of person.

7. according to the method described in claim 1, it is characterised in that also include the VLAN industry issued to gateway in the process Configuration data of being engaged in carries out the global validity checking of port traffic configuration data, specifically includes：

Operated before each business configuration once, software receives the VLAN traffic of port with postponing, every business of circular test Whether parameter is correct effectively, and flow will be examined in whether type of service is " unicast " or " multicast ", the private network VLAN behaviour of port Whether operation mode is " pattern 1 ", " pattern 2 ", " one of pattern 3 ", private network VLAN tag value, public network VLAN tag value, TLS Whether VLAN tag value meets IEEE802.1 regulations, and public network VLAN tag, which enables mark, TLS VLAN tags and enabled, to be marked whether For " enable " or " going to enable ", each VLAN traffic inspection to the port terminates, as long as one of attribute value mistake This configuration failure will be returned；

Pattern 1：Up addition private network VLAN tag and descending stripping；

Pattern 2：Up-downgoing carries the message transparent transmission for specifying private network VLAN tag；

Pattern 3：Up-downgoing symmetrically switches the message VLAN tag for carrying and specifying private network VLAN tag；

TLS：Transparent Ethernet.

8. method according to claim 6, it is characterised in that be compared the configuration data of new business and current business The step of also including port traffic collision detection before, it is specially：

The service counting table SCT that reference service is classified with counting process, judges multicast TAG business, unicast ALL respectively Whether TRANSPARENT business, unicast TLS business, unicast TAG business, the operation count of unicast TAG＆QinQ business are more than 1, As long as when one of them draws the judged result more than 1, representing there is the corresponding principle for violating port traffic conflict；

For each business configuration data, its private network VLAN tag and the private network VLAN tag of other all business are compared Compared with if private network VLAN tag is unequal, continuation and other business compare, if private network VLAN tag is equal, compare both Private network VLAN operator schemes, when the pattern of the two is unequal, represent there is the corresponding principle for violating port traffic conflict；

For unicast VLAN traffic, do not drawn after completeer private network VLAN tag and private network VLAN operator schemes and " violate end During the corresponding principle of port service conflict " conclusion, in addition it is also necessary to which comparing the two public network VLAN enables mark and public network VLAN tag is It is no consistent；As long as when have one it is inconsistent when, represent exist violate port traffic conflict corresponding principle；

Multicast TAG business：When the downlink message for carrying specified private network VLAN tag flows through ONU, ONU first peels off the VLAN tag again Forwarded to user port；

Unicast TAG business：When the up message for not carrying VLAN tag flows through ONU, ONU is one layer of private network VLAN mark of its addition Label；When the descending message for carrying the private network VLAN tag flows through ONU, ONU first peels off the VLAN tag, then turns to user port Hair；

Unicast ALL TRANSPARENT business：ONU does not perceive private network VLAN tag and public network VLAN tag, realizes all messages Transparent transmission；

Unicast TLS business：When the up message for not carrying VLAN tag flows through ONU, ONU specifies private network VLAN marks for its addition Label, when the up message for carrying other private network VLAN tags flows through ONU, ONU adds public network VLAN tag for it；Carried when descending When the message of two layers of VLAN tag of the above flows through ONU, ONU first peels off public network VLAN tag, is then forwarded to user port, instantly When the message that row carries specified private network VLAN tag flows through ONU, ONU first peels off private network VLAN tag, then turns to user port Hair；

Unicast TAG＆QinQ business：When the up message for not carrying VLAN tag flows through ONU, ONU adds private network VLAN marks for it While label, public network VLAN tag is added in its outer layer；When more than descending carrying the message of two layers of VLAN tag flows through ONU, ONU Two layers of VLAN tag is first peeled off, is then forwarded to user port.

9. the system of user port VLAN traffic management is realized in a kind of optical network unit, it is characterised in that the system includes：

First memory space, for preserving the corresponding VLAN traffic configuration data attribute list of each user port, the VLAN industry Configuration data of being engaged in attribute list is used for the corresponding VLAN traffic configuration data of each VLAN traffic of the book of final entry and each class VLAN The number of operations of business, the VLAN traffic configuration data attribute list includes：For recording the corresponding VLAN of each class type of service Business grouped data table TST, the type of service table STT for every new VLAN traffic type of the book of final entry of business configuration data With the service counting table SCT for recording each class VLAN traffic number of operations, type of service table STT numberings and statistic record industry It is each in the type of service title of business, service counting table SCT corresponding record type of service tables STT in business grouped data table TST The number of operations of class VLAN traffic, is renamed after STT and SCT tables locally preserve；

Second memory space, for the VLAN traffic configuration data issued from gateway according to reception, forms portion and meets institute The new form of VLAN traffic configuration data attribute list statistical rules is stated, and is preserved；

Comparison module, for comparing the list data in first memory space and the second memory space, is marked described new The inconsistent VLAN configuration datas of VLAN traffic configuration data attribute list in form and first memory space, as comparing knot Really；

Configuration driven module, updates related service hardware and logic, come into force business configuration according to the comparative result.
