Abstract
The collocation method of a kind of Gbit passive optical network system of the present invention, comprising: utilize OLT for ONU is arranged plural ID; For distributing at least one port under each ID; Different ID is arranged to different SFU and/or MDU; OLT is that different SFU and/or MDU creates respective functional module.Effect of the present invention is: all advantages not only having MDU and SFU concurrently, also have the following advantages: only need upgrade software, just can realize the lifting of functions of the equipments, has saved a large amount of manpower and materials cost, has saved the input of new equipment; The more change of adaption demand, can according to the different demands of user, the port of dynamic distributing user and port number.
Description
Technical field
The present invention relates to a kind of collocation method of Gbit passive optical network system.
Background technology
The life of modern more and more be unable to do without network.On network, everybody can chat and make friends, and lower data of can seeing a film, can play games ...All for family charged electrical equipment has all been connected net by the development of Internet of Things.Even if thousands of miles away, we also can by any can the equipment of access network, the electrical equipment of management family.
The increase of network application, requires more stable, faster network access equipment.Gigabit passive optical network equipment (GPON) is exactly the first selection addressed these problems.It can provide descending maximum 2.5G, the network speed of up maximum 1.25G.Can provide the multiple scheduling strategy such as SP, WRR, SP+WRR, distribute bandwidth.
Gigabit passive optical network access scheme generally has FTTB (FibertoTheBuilding), FTTH (FibertoTheHome) two kinds.FTTB generally uses MDU product, has the product form such as 8FE, 16FE, 24FE.FTTH generally uses SFU product, has the several prods forms such as 1GE, 4FE, 4GE.
The SFU advantage main relative to MDU is exactly the service that operator can control to be supplied to user more accurately.Any difference be there is no concerning SFU, MDU user, because the network speed of 100M is enough at present.Namely use the SFU product of 1GE, operator also can only provide the set meal of 10M or 20M to select.
The advantage of the relative MDU of SFU has: to the service being supplied to user, provide and control more accurately; Reduce the mutual interference between user.
MDU has relative to the advantage of SFU: because MDU has generally gathered a special exchange chip, can provide the functions such as more powerful ACL, DHCP, PPPOE, 802.1X; Because MDU product is placed on corridor, facilitates and administer and maintain; Due to GPON optical fiber out be all laser, do not place the possibility that it also avoid laser hazard human body at home.
In advance because local side apparatus OLT (opticallineterminal, optical line terminal) is to the restriction of lower extension number of devices, when local side apparatus is insufficient, deployment be all MDU product.And now, the SFU product of fiber entering household gets more and more, when not upgrading hardware, Gbit passive optical network system can not meet MDU product and SFU product.
Summary of the invention
The object of the present invention is to provide a kind of collocation method of Gbit passive optical network system, solve the problem that current Gbit passive optical network system cannot meet MDU product and SFU product needed.
For solving the problem, the technical solution used in the present invention is:
A collocation method for Gbit passive optical network system, comprises
Utilize OLT for ONU is arranged plural ID;
For distributing at least one port under each ID;
Different ID is arranged to different SFU and/or MDU;
OLT is that different SFU and/or MDU creates respective functional module.
Further, due to the operation in order to insure completely, the described OLT of utilization is plural ID for ONU is arranged, and after distributing at least one port, preserves and restarts under each ID.
The beneficial effect adopting technique scheme to produce is: all advantages not only having MDU and SFU concurrently, also have the following advantages:
1, only need upgrade software, just can realize the lifting of functions of the equipments, saved a large amount of manpower and materials cost, saved the input of new equipment.
2, the change of more adaption demand, can according to the different demands of user, the port of dynamic distributing user and port number.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of a collocation method embodiment of a kind of Gbit passive optical network system of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 shows an embodiment of the collocation method of a kind of Gbit passive optical network system of the present invention: a kind of collocation method of Gbit passive optical network system, comprises
Utilize OLT for ONU is arranged plural ID;
For distributing at least one port under each ID;
Different ID is arranged to different SFU and/or MDU;
OLT is that different SFU and/or MDU creates respective functional module.
According to a preferred embodiment of the collocation method of a kind of Gbit passive optical network system of the present invention, due to the operation in order to insure completely, the described OLT of utilization is plural ID for ONU is arranged, and after distributing at least one port, preserves and restarts under each ID.
Wherein, ID can be repetition, the port that ID repeats, and forms little SFU or MDU.Each functional module will create identical part, but every a ID distributed is different.ID is different, but the identical functional module function and usage of title is identical, and the object of just service is different with the object communicated.Can communicate between the functional module of identical ID, can not communicate between the functional module of different I D.The functional module of identical ID gathers, and forms little SFU or MDU.
Illustrate by the ONU product lists of 16 mouthfuls:
OLT issues configuration.Require that the ID of 1,2 ports is 1, the ID of 3,4 ports is 2, and the ID of 5 to 16 ports is 3.Namely mean, 1,2 ports form a SFU, and 3,4 ports form a SFU, and 5 to 16 ports form a MDU.
Port order can be random, also can configure and make 1, and 3 ports form a SFU, and 2,5 ports form a SFU, and 4,6,7,8,9,10,11,12,13,14,15,16 ports form a MDU.
ONU preserves configuration, restarts.First ONU loads configuration after starting, and for the ID quantity of distributing, each functional module will create the module of respective amount.
Such as service resolution module, finds that there is 3 different ID according to configuration, and will create 3 identical service resolution modules, the function of these 3 service resolution modules is consistent, but service object is different, and the communication object that can communicate is also different.Service resolution module 1 is only the miniport service of 1 to ID, only and ID be 1 other module communications.Service resolution module 2 is only the miniport service of 2 to ID, only and ID be 2 other module communications.The rest may be inferred, and service resolution module 3 is only the miniport service of 3 to ID, only and ID be 3 other module communications.
OLT, according to configuration before, manages this ONU, safeguards 3 ONUID.Split, each little SFU or MDU has corresponding collocation channel, and configuration is forwarded to corresponding service resolution module.
Although also share a set of hardware, he is divided into little SFU or MDU separate one by one by software change.
Although with reference to multiple explanatory embodiment of the present invention, invention has been described here, but, should be appreciated that, those skilled in the art can design a lot of other amendment and execution mode, these amendments and execution mode will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the building block of subject combination layout and/or layout.Except the modification of carrying out building block and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
