Embodiment
Describe the present invention below with reference to the accompanying drawings in detail.
With reference to Fig. 1, the business management method that is used for gigabit passive optical network according to the present invention may further comprise the steps:
Step S102, webmaster are the business configuration service attribute that network unit/optical network terminal is supported.
Service attribute can comprise port-mark and transmission container.Service attribute can also comprise mapping relations and/or the User network interface ports between Business Stream and the port-mark.
Step S104 when optical line terminal is connected to network unit/optical network terminal, receives service attribute, thereby obtains the type of service that network unit/optical network terminal is supported.
Step S106 if the optical line terminal supporting business is then carried out establishment, and sets up the association between each management entity.
Alternatively, if optical line terminal is not supported certain business, then on webmaster, do not allow to carry out and create.
Alternatively, create the Gigabit passive optical network packaging mode port-mark for network unit/optical network terminal, in step S104, optical line terminal also obtains the Gigabit passive optical network packaging mode port-mark quantity of support.If the quantity of Gigabit passive optical network packaging mode port-mark surpasses the maximum port-mark quantity of being supported, then on webmaster, report an error.
Preferably, after the establishment business, allow as required service parameter to be made amendment and increase.Alternatively, after the establishment business,, then allow service parameter is carried out corresponding modify and increase if carried out other establishment and management as required.Can revise or increase service parameter by revising example in the management entity.Can realize by deleting earlier to create again for the modification of creating the read only attribute service parameter.
Main method of the present invention is at first to take out the common characteristic of various types of traffic; Next obtains the kind of the benchmark service type of ONU/ONT support; At last set up business relations and subsequent treatment between each ME according to various types of traffic.Wherein, partly handle automatically for second step and final step in network element OLT side, the subsequent treatment of last one need be handled according to type of service, the type of service that has may need, what have will not need further processing, and the characteristic that the various types of traffic that takes out is total only disposes these total characteristics for thoroughly webmaster, webmaster, like this can the different ONU/ONT of unified management on webmaster, and the dissimilar business of various ONU/ONT.
Below we will give an example and describe the method for its specific implementation:
The first step, by to Fig. 2-Fig. 5, and the analysis of the ME graph of a relation of in standard, not listing, we can take out the total attribute that each type figure (perhaps type of service) comprises: PortId (port-mark), T-CONT (transmission container, TransmissionContainer), and the mapping relations between Business Stream and the PortId, what have may also comprise UNI (User Network Interface, User Network Interface) port.We will be when configuration professional on each ONU/ONT like this, to comprise following object, specify its type of service (to need to guarantee that this type of service ONU/ONT supports, its ensuring method is introduced in next step), PortId, the T-CONT that PortId enters, and the Business Stream that may comprise is mapped to the rule of PortId, also might need to comprise uni port.
Second step, obtain the benchmark service type that ONU/ONT supports, we can arrange the example (Instance) that (perhaps increasing) is used to report or inquire about its business support ability in advance in standard, for example can increase by two examples down at certain ME (for example ONT-G or ONT2-G), one is used for ONU/ONT and supports GEM (G-PONEncapsulation Method, the GPON method for packing) Feng Zhuan type of service ability, another is used to support ATM (Asynchronous Transfer Mode, asynchronous transfer mode) Feng Zhuan business support ability etc., in addition, preferably be increased in the example of the PortId quantity of supporting under every kind of type of service again.Like this in the OLT side by MIB UPLOAD (obtaining the mib object that ONU/ONT go up to support), perhaps direct GET can learn type of service and PortId quantity that ONU/ONT supports.After the type of service of obtaining the ONU/ONT support, when carrying out service management, can at first judge whether to support this business, if unsupported business, on webmaster, just do not allow its establishment, reduced its possibility of makeing mistakes so simultaneously, increased manageability and controllability ONU/ONT.Can also control the ability of the PortId of each ONU/ONT support in addition,, also on webmaster, directly report an error if exceed this ability.If do not define some unified standard attributes, then when each manufacturer docks, need link up in advance, your ONU/ONT supports any type of service, supports how many PortId, OLT supports any type again, need artificial prior participation, if there is such Instance, complete participation without personnel, only need be with equipment interconnection, it is just passable to carry out the business configuration management then.
The 3rd step, owing in GPON, there are various ONU/ONT, and the class of business that ONU/ONT supports is abundant, after establishment, set up the association between each ME, can guarantee under the situation about having that business can be normal, but the miscellaneous service parameter may not guarantee that one satisfies user's demand surely, therefore need be after establishment and professional normal back we can be by revising the demand that its service parameter satisfies the user; Under the situation about also having, can not satisfy user's business demand after the establishment, not only on service parameter, the real bridge among Fig. 2 for example, we can only unify creative management (is MAC (the Media Access Control of GEM side to the upper united mouth of bridge, the medium access control) Bridge PortConfiguration Data), LAN (Local Area Network, local area network (LAN)) MACBridge Port Configuration Data of side (media access control bridge port configuration data management entity class) and uni port need other creative management, and Fig. 5 we can only unify to create and manage ATM IW (Interworking, intercommunication) TP (TerminationPoint, destination node) IP of side (Internet Protocol, Internet protocol) PortConfiguration Data (Internet protocol port configuration data management entity class), remaining relevant information (ME etc.) need be created and manage by other mode, in this case, the service parameter that has etc. also needs to revise or increase the demand that satisfies in the user management.
Illustrate its execution mode below, we will set forth with Fig. 2 and Fig. 4, and other service conditions are similar:
In Fig. 2, may there be four kinds of situations, promptly be respectively:
1, the LAN of empty bridge does not have the mode of 802.1p;
2, the LAN of empty bridge adds the mode of 802.1p;
3, really there is bridge, do not have the 802.1p mode;
4, real bridge adds the 802.1p mode.
Only need specify PortId for first kind of situation, T-CONT, and uni port, on OLT, receive after these information, and then unified distribution resource, create GEMPort Network CTP (Connection Termination Point, connection end points) (the port network destination point of Gigabit passive optical network packaging mode), GEM IW TP, GAL (GEM Adaptation Layer, the GEM adaptation layer) Ethernet Protfile (the interconnection node of Gigabit passive optical network packaging mode) and MAC BridgeService Profile (media access control bridge service model), the MAC Bridge Port Configuration Data of GEM side and LAN side is according to the information (ME etc.) and the UNI that create, each ME in the associated diagram, whole service is created successfully like this, and business can be normal.
Only need specify PortId for second kind of situation, T-CONT, mapping ruler (being the priority of 802.1p and the mapping between the PortId) and uni port between portId and the stream, on OLT, receive after these information, and then unified distribution resource, create GEM Port Network CTP, GEM IW TP, GAL Ethernet Protfile, and 802.1p mapper service profile (802.1p shines upon business model), MAC BridgeService Profile, the MAC Bridge Port ConfigurationData of GEM side and LAN side is according to the information of creating (ME etc.) and UNI (for the unique GEM side of UNI correspondence and the MAC Bridge Port Configuration Data of LAN side), each ME in the associated diagram, whole service is created successfully like this, and business can be normal.
Only need specify PortId for the third situation, T-CONT, on OLT, receive after these information, and then unified distribution resource, create GEM Port NetworkCTP, GEM IW TP, GAL Ethernet Protfile, and MAC Bridge ServiceProfile, the MAC Bridge Port Configuration Data of GEM side, according to the information of creating (ME etc.), each ME of GEM side in the associated diagram, the service creation of GEM side turnover bridge success like this (can be provided with separately if also need to control whole service then also need bridge is provided with, needn't unify, it is included into the particular attribute of different service types).
Only need specify PortId for the 4th kind of situation, T-CONT, mapping ruler (being the priority of 802.1p and the mapping between the PortId) between portId and the stream, on OLT, receive after these information, and then unified distribution resource, create GEM PortNetwork CTP, GEM IW TP, GAL Ethernet Protfile, and 802.1pmapper service profile, MAC Bridge Service Profile, the MACBridge Port Configuration Data of GEM side, according to the information of creating (ME etc.), each ME of GEM side in the associated diagram passes in and out the service creation success of bridge like this, (can be provided with separately if also need to control whole service then also need bridge is provided with, needn't unify, it is included into the particular attribute of different service types).
After creating successfully, we can change its service parameter etc. by the instance that revises among each ME.For example, can revise up-downgoing priority query among its CTP (being Priority Queue Pointer for Upstream and Priority Queue Pointer forDownstream), and to PPTP (Physical Path Termination Point, the physical channel destination node) parameter among the Ethernet UNI (user network side Ethernet interface) is made amendment, Auto Detection Configuration (rate configuration) for example, Administrative State (controlled state), the modification of MaxFrameSize (the maximum frame length of Ethernet) etc., and the direction among the CTP (being Direction).To there be difference for being modified in the processing of this dual mode, because the up-downgoing formation can only be provided with when creating among the CTP, be read only attribute after creating successfully, can not revise, therefore its processing mode is to delete this CTP earlier, and then adopt the Instance of new settings to create this CTP, promptly the mode of revising for the Instance of the type is deletion earlier and then creates (may be the deletion of a series of relevant ME and establishment again, rather than only be a ME of this Instance correspondence).Direction for Instance among the PPTP Ethernet UNI and CTP then takes another mode, because its attribute itself is just supported to revise, this Instance comes into force after promptly revising, therefore to the direct alter mode of the employing of such Instance, do not need to do again other work.
In addition, for having bridge, we may also need to handle the MACBridge Port Configuration Data of LAN side, and it is related with certain UNI mouth, may also need to set up the rule of some L2 (2 layers) then, as long as like this, whole service is handled just to calculate and is finished.
In Fig. 4, only need to specify PortId, T-CONT, uni port, on OLT, receive after these information, and then unified distribution resource, create GEM PortNetwork CTP, GEM IW TP, and GAL TDM Profile (Gigabit passive optical network packaging mode adaptation layer TDM service model), CES (Circuit EmulationService, circuit emulation service) Service Profile (circuit emulation service model), Logical Nx64kbit/s Sub-port Connection Termination Point (N road 64k bits per second logical sub port destination point), according to the information (ME etc.) and the UNI that create, each ME in the associated diagram, the success of the CES service creation on ONU/ONT like this is professional normal.
Like this, we only need be by being provided with the total attribute of various types of traffic, on network element, create automatically, can either guarantee on webmaster the different business of can unified management different ONU/ONT like this, and can guarantee to create simply and effectively service management, the GPON business of complexity is oversimplified in management.
The present invention mainly is from the aspects such as simplification of service management the GPON system and realization are considered, because the GPON type of service is more, the type of service that various ONU/ONT support is also inequality, GPON is professional own with regard to more complicated in addition, give in user's the management like this and bring bigger difficulty, also there is big difficulty in unified management to the ONU/ONT of each manufacturer, adopts this method to address these problems with comparalive ease.Only for example understand the method for the business of a kind of abstract management ONU/ONT in this article, also can adopt thought of the present invention, adopt the abstract simplification service management of additive method.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
