Embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, limit is not used to The fixed present invention.
The present invention provides a kind of multicast service monitoring method, reference picture 1, in multicast service of the present invention monitoring In the first embodiment of method, the multicast service monitoring method includes：
Step S10, the multicast service of synchronous different types of mirror image entity and target optical network unit, its In, all types of mirror image entities correspond to the multicast service of target optical network unit in each turn of optical line terminal respectively Send out the replica node of level；
It should be noted that compared with traditional access network technology and Ethernet Exchanger Technology, xPON Physical layer be point-to-multipoint topological structure, its downlink data uses physical-layer broadcasts mode, that is, Say, downlink data can be sent to terminal devices all on link, i.e. optical network unit.In physical layer On the basis of, xPON link layers establish unicast channel in logic, and common unicast service can pass through Logic unicast channel is sent to optical network unit.But for multicast service, if also walking unicast channel It is intended to do substantial amounts of multicast packet packet replication in optical line terminal side, adds answering for equipment realization Miscellaneous degree, it is often more important that, the duplicated multicast bag of big flow can cause very big waste to link bandwidth.Cause This, in current xPON networks, the forwarding of group business stream all make use of the characteristic that physical layer descending is broadcasted Directly walk broadcast channel and be sent to optical network unit.
For local side apparatus optical line terminal, the telecom carrier-class device of main flow is used all in forwarding surface Be PON plates, power board add yoke plate framework.Therefore, the duplication of multicast service generally will be in PON Multiple nodes in equipment are carried out, for example, group business stream needed on power board multiple PON plates it Between replicated, need to be replicated between multiple PON mouthfuls on PON plates.Work as group business stream When being copied to PON mouthfuls of ranks, it will not continue to replicate between optical network unit, but use descending Multicast or broadcast channel optical network unit is transmitted to single copy mode.The forwarding of foregoing group business stream During, optical line terminal is replicated from source port receiving multicast business stream, source port as the one-level of multicast Node, is normally on control panel/power board；By traffic distribution to forwarding end under the control of multicast protocol Mouthful, forwarding port is then two grades of replica nodes of multicast.It should be noted that foregoing one-level replica node And two grades of replica nodes can be one, or it is multiple.There is two level forwarding with optical line terminal below Level is illustrated.It will be appreciated by persons skilled in the art that in other embodiments, optical line terminal Also can only possess one-level forwarding level or the forwarding level more than two-stage.
In the present embodiment, before step S10, in addition to：
Multicast service based on target optical network unit sets correspondence mesh in the forward-path of optical line terminal The first kind mirror image entity and Equations of The Second Kind mirror image entity of optical network unit are marked, specifically can be by target optical-fiber network list The multicast service of member is used as mirror image source in the first replica node and the second replica node of optical line terminal Mouthful, set and using the mirror image destination interface of the first replica node as target optical network unit the first eka-ytterbium As entity, set and regard the mirror image destination interface of the second replica node as the second of target optical network unit Class mirror image entity.Wherein, first replica node and second replica node are located at different forwardings Level, when such as the first replica node is one-level replica node, the second replica node is two grades of replica nodes.
In addition, target optical network unit can be configured by manmachine command mode, user can be on demand by light The object that any optical network unit of the line terminal second line of a couplet is monitored as multicast service, i.e. target optical-fiber network list Member.
The setting of target optical network unit mirror image entity is illustrated below in conjunction with Fig. 2：
As shown in Fig. 2 source port (one of the group business stream from multicast source in optical line terminal power board Level replica node) first order duplication is carried out, the group business stream after duplication is distributed to turning on each PON plates Originator mouth (two grades of replica nodes), by forwarding port to carry out second level duplication, the group business stream after duplication Flow to target optical network unit and other optical network units.
When setting the first kind mirror image entity of target optical network unit, selection and target optical network unit group The all or part of identical entity of Business Stream forward-path or interface are broadcast, is included but is not limited to and target light net Network unit specific multicast service passes through the upper united mouth of identical one-level replica node；Target optical-fiber network list is being set Member Equations of The Second Kind mirror image entity when, selection with target optical network unit group business stream forward-path all or Part identical entity or interface, include but is not limited to pass through with target optical network unit specific multicast service Identical one-level and the second line of a couplet mouthful of two grades of replica nodes.
In the present embodiment, because the first kind mirror image entity and the Equations of The Second Kind mirror image entity are right respectively Answer the multicast service of target optical network unit in the first replica node of optical line terminal difference forwarding level and Second replica node, by the synchronous first kind mirror image entity and the Equations of The Second Kind mirror image entity with it is described The multicast service of target optical network unit, can not influence target optical network unit perceive in the case of, By the specific multicast service stream of target optical network unit from the different lossless extractions of forwarding level, for follow-up right The multicast service of target optical network unit carries out analysis monitoring.
Step S20, carries out traffic statistics, and obtain to the multicast service of all types of mirror image entities after synchronization Take the default abnormal corresponding conditional parameter of multicast service forwarding；
Step S30, when the result of traffic statistics meets the conditional parameter, determines the target light net The multicast service forwarding of network unit is abnormal, and determines the abnormal forwarding level being located at.
In the present embodiment, the mode of traffic statistics includes but is not limited to keeping count, according to multicast channel Multiple counting of protocol switching etc..Wherein, the flux of multicast statistical counting of different mirror image entities is contrasted, can To calculate the flux of multicast of different levels replica node, by contrasting the flux of multicast of different mirror image entities, It can confirm that whether the multicast service of target optical network unit is abnormal in the forwarding of optical line terminal.In correspondence , can be by man-machine after the first kind mirror image entity and Equations of The Second Kind mirror image entity of setting target optical network unit Order and clear history traffic statistics order is performed to the first kind mirror image entity and Equations of The Second Kind mirror image entity of setting And traffic statistics order so that the first kind mirror image entity of setting and the history stream of Equations of The Second Kind mirror image entity Amount statistics is emptied simultaneously, and restarts traffic statistics simultaneously.
Specifically, the multicast service of the first kind mirror image entity correspondence objective network unit set is in optical link The one-level replica node of terminal, the multicast industry of the Equations of The Second Kind mirror image entity correspondence target optical network unit of setting It is engaged in two grades of replica nodes of optical line terminal.To first kind mirror image entity and Equations of The Second Kind mirror image entity When multicast service carries out traffic statistics, including normal message is counted and exception message is counted, wherein, it is abnormal Message includes but is not limited to drop messages and error messages.The abnormal corresponding condition ginseng of multicast service forwarding Number includes the abnormal first condition parameter of correspondence one-level replica node forwarding, two grades of replica node forwardings of correspondence Forwarded between abnormal second condition parameter, and correspondence one-level replica node and two grades of replica nodes abnormal Third condition parameter etc..
Traffic statistics to first kind mirror image entity multicast service are realized to specific multicast source (target optical-fiber network Multicast source where the corresponding multicast group of unit) and one-level replica node traffic monitoring, wherein, normally Packet counting can calculate the specific multicast service flow by one-level replica node；Exception message is counted Growth pattern can be realized to be monitored to the multicast service transfer quality of one-level replica node, if exception message Sustainable growth (the meeting first condition parameter) in the first preset time period is counted, illustrates one-level replica node Forwarding is abnormal.
Traffic statistics to Equations of The Second Kind mirror image entity multicast service realize two grades that specific multicast source is passed through again The traffic monitoring of node processed, wherein, normal message, which is counted, can calculate the spy by two grades of replica nodes Determine multicast service flow；Exception message, which counts growth pattern, can realize the multicast service to two grades of replica nodes Transfer quality is monitored, if exception message counts the sustainable growth in the second preset time period and (meets the Two conditional parameters), illustrate that two grades of replica node forwardings are abnormal.It should be noted that the first preset time period May be configured as with the second preset time period identical, may be alternatively provided as difference, for example, can by first it is default when Between section and the second preset time period be set to 5 seconds simultaneously.
It is first poor by calculate that the normal message of first kind mirror image entity and Equations of The Second Kind mirror image entity counts Value, and the first difference of calculating and the first predetermined threshold value are compared, realize the stream between two-stage node Amount monitoring, wherein, when the first difference of calculating is more than the first predetermined threshold value (meeting third condition parameter) When, the forwarding between one-level replica node and two grades of replica nodes is abnormal.
Further, in the present embodiment, can also be between optical line terminal and target optical network unit Forwarding channel is monitored, specifically, in the step of aforementioned flow is counted, can also be to the target light The group business stream of the actual reception of NE carries out traffic statistics, and the multicast service forwarding is abnormal corresponding Conditional parameter also include the abnormal fourth condition parameter of correspondence target optical network unit forwarding channel.Complete After the traffic statistics of the group business stream of the paired actual reception of target optical network unit, second is calculated The second difference that the exception message of class mirror image entity and target optical network unit is counted, and by the second of calculating Difference is compared with the second predetermined threshold value, wherein, preset when the second difference of calculating is more than described second During threshold value (meeting fourth condition parameter), the forwarding channel of the target optical network unit is abnormal.Generally , the forwarding channel of target optical network unit may be led by optical link quality or other factorses interference extremely Cause.
In addition, the forwarding capability of itself can be also monitored to target optical network unit, specifically in completion pair After the traffic statistics of the group business stream of the actual reception of target optical network unit, the second eka-ytterbium is calculated As the 3rd difference that the normal message of entity and target optical network unit is counted, and by the 3rd difference of calculating It is compared with the 3rd predetermined threshold value, wherein, when the 3rd difference of calculating is more than the 3rd predetermined threshold value When, the forwarding capability of the target optical network unit itself is abnormal, or except normal group business stream it Outside, other Business Streams are forwarded to target optical network unit, it is excessive to cause to exceed band width configuration.
Further, in the present embodiment, the quality in specific multicast source can be also monitored, specifically, Channel is broadcast when detecting target optical network unit switch groups, that is, when switching the multicast group of addition, if any set The exception message for the mirror image entity put is counted and (can specifically set according to actual needs in the 3rd preset time period Put, for example, can be set to the 3rd preset time period 5 seconds) in do not increase, specific program source is abnormal.
Further, in the present embodiment, to avoid outside group business stream other Business Streams to foregoing stream Amount statistical operation is impacted, and while step S10 is performed, also performs following steps：
Shield other Business Streams of all types of mirror image entities in addition to group business stream.
The multicast service monitoring method that the present embodiment is proposed, passes through the different forwarding levels in optical line terminal The different types of mirror image entity of correspondence target optical network unit is set, target optical network unit is not being influenceed By the group business stream of target optical network unit from the different lossless extractions of forwarding level in the case of perception, And then the group business stream drawn by different forwarding levels forwards the forwarding of level to optical line terminal difference Quality is monitored, and is completed in the case of not against outside other equipment or program source whole to optical link The abnormal positioning of the different forwarding levels in end, reaches the purpose for realizing the monitoring to optical line terminal multicast service, And with higher accuracy.
Further, based on first embodiment, propose that the second of multicast service monitoring method of the present invention is implemented Example, in the present embodiment, after step S30, in addition to：
Output carries the warning information of abnormal forwarding level.
It should be noted that the difference of the present embodiment and first embodiment is, the present embodiment is in completion pair The forwarding of the multicast service of the target optical network unit judges extremely, and determines the target optical-fiber network list When the multicast service forwarding of member is abnormal, also output carries the warning information of abnormal forwarding level, with directly perceived The abort situation for informing that user multicast service is abnormal.
In addition, the warning information of output can also include the interface message of the abnormal replica node of forwarding.Example Such as, count the sustainable growth in the first preset time period in the exception message of first kind mirror image entity, i.e., it is full During sufficient first condition parameter, determine that the forwarding of one-level replica node is abnormal, the warning information of output is " one-level Replica node forwarding is abnormal "+" interface message of one-level replica node ".
Further, in the present embodiment, abnormal alarm function is forwarded on demand to be opened by user.With Family can specifically be opened by manmachine command, webmaster or other operational systems and forward abnormal alarm function, and The forwarding level of alarm is can further specify that, for example, user may specify unlatching " one-level replica node " Alarm function, then and it is only abnormal in the forwarding of " one-level replica node " when, can just export corresponding announcement Alert information.
Further, based on first embodiment, propose that the 3rd of multicast service monitoring method of the present invention implements Example, in the present embodiment, before step S10, in addition to：
Replica node by the multicast service of target optical network unit in each forwarding level of optical line terminal is made For mirror image source port, all types of mirror image entities of target optical network unit are correspondingly arranged, and it is each for what is set Type mirror image entity configuration synchronous mode, wherein, the synchronous mode includes first mode and second mode；
The step S10 includes：
All types of mirror image entities are chosen, and determine the synchronous mode of mirror image entity chosen；
If the mirror image entity chosen is first mode, the group that the target optical network unit is sent is being received Broadcast and group add or leave message, and the target optical network unit is successfully joined or left corresponding multicast group When, the group business stream of the multicast group is accordingly introduced or by the end of the mirror image entity chosen；
If the mirror image entity chosen is second mode, the group that the target optical network unit is sent is being received Broadcast when group adding or leave message, the group business stream of the multicast group is accordingly introduced or by the end of choosing Mirror image entity.
It should be noted that the difference of the present embodiment and first embodiment is, the present embodiment is setting the While one class mirror image entity and Equations of The Second Kind mirror image entity, also for setting the first kind mirror image entity and The Equations of The Second Kind mirror image entity configuration has synchronous mode.
Synchronous mode refer to mirror image entity action based on multicast protocol and target optical network unit action it Between follow relation, include but is not limited to follow (first mode) and do not follow (second mode), wherein, " following " refers to protocol action result of the action of mirror image entity dependent on target optical network unit；" not following " Refer to mirror image entity action only rely upon target optical network unit protocol action request, and independent of The result of the action of target optical network unit.
Further, based on 3rd embodiment, propose that the 4th of multicast service monitoring method of the present invention implements Example, in the present embodiment, has the synchronous mode of mirror image entity configuration different, step in all types of mirror image entities After rapid S10, in addition to：
