Background technology
The PON technology is the technology of a kind of point to multiple spot, comprises Ethernet passive optical network (EPON, EthernetPassive Optical Network), gigabit passive optical network (GPON, Gigabit Passive OpticalNetwork) etc.Mention in the standard that International Telecommunications Union (ITU, International Telecommunications Union) formulates at the GPON fundamental characteristics, with present physical-layer techniques level, 1: 64 light is along separate routes than being more satisfactory; Consider the development of optical module technical merit, the light of GPON equipment can reach 1: 128 than maximum along separate routes.Equally, in EPON equipment, light is along separate routes than also having reached 1: 64 at present.
Optical line terminal (the OLT of PON equipment local side, Optical Line Terminal) with the Optical Network Terminal (ONT of user side, Optical Network Termination) or between the optical network unit (ONU, OpticalNetwork Unit) be connected by passive fiber.Each OLT links to each other with a plurality of ONU by passive optical splitters, and light is the ability of the single OLT ONU quantity that can connect than reflection along separate routes.This characteristic is the big advantage that PON access device OLT compares other broadband access equipment, and therefore so numerous subscriber terminal equipment of the inevitable number of connection of networking mode even have only an OLT, also will have 128 ONU and be attached thereto.
The User Network Interface of PON ONU equipment (UNI, User Network Interface) value volume and range of product is all a lot.With GPON is example, and according to the definition of the management entity (ME, Management Entity) of UNI side physical channel destination node, the user port number of last each the groove position of ONU can reach 255 at most, but not also has a plurality of grooves position on the integrated form ONU.In addition, the type of the UNI of GPON ONU can be Ethernet, circuit emulation service, plain old telephone service, integrated services digital network, video, various Digital Subscriber Line (xDSL, x Digital Subscriber Line) or the like, the attribute of every type of UNI is all inequality.All these relevant device configuration informations all need to preserve, therefore the problem of resource occupation has occurred, it specifically is exactly the preservation of relevant configuration data such as business, equipment, port in the PON equipment, need take the storage resources of a large amount of systems nonvolatile RAM (NVRAM, Non-Volatile Random Access Memory).
PON equipment carries out telemanagement by local side OLT to user side ONU, and under this centralization, a large amount of configuration datas are kept on the OLT equipment, and itself does not preserve data terminal equipments such as ONU.The wherein major part of the data of preserving among the OLT relates to the relevant configuration information of each ONU, comprise configuration at its each UNI, and the configuration of professional join dependency, in same PON, a big chunk data are identical in these configuration informations, perhaps can be divided into several.On OLT, preserve configuration data and promptly be the configuration data that to move in the internal memory and store among the NVRAM, so that when equipment restarts, from configuration script, recover relevant configuration data with the form of file.OLT is last can to preserve into single configuration script with the configuration data of all ONU, also can preserve a configuration script separately at each ONU.The former makes things convenient for the management of configuration script, problem be configuration script too big and can't be between ONU shared configuration script, if revise or delete the relevant configuration of certain ONU, must from big configuration script, find configuration data that should the ONU position is made amendment or deleted.A kind of method in back is convenient to configuration script reusing between ONU, and the configuration script of an ONU is made an amendment slightly just goes for another ONU, and the configuration of revising, deleting certain ONU also can directly be revised or delete configuration script that should ONU.At present when adopting second method, still preserved the configuration data of all ONU, just configuration data a plurality of configuration scripts have been divided into by ONU, the total size of configuration script does not have too big variation, do not have to simplify relevant user's configuration step yet, and when the ONU number is numerous, can produce the problem of memory space resource anxiety.

Embodiment
Main thought of the present invention is: based on the most similar even identical situation of the configuration script of terminal equipment in the EPON, one class configuration data is basic identical, have only a small amount of configuration data difference, promptly dispose in the similar terminal equipment configuration script one and be set to share configuration script, quote shared configuration script during the similar terminal equipment configuration of subsequent configuration, only preserve configuration information and the incidence relation different, saved memory space greatly with shared configuration script.In the terminal unit remote management of method of the present invention applicable to EPONs such as EPON, GPON, the telemanagement of these networks all can relate to the layoutprocedure of local side apparatus to terminal equipment.
Below in conjunction with Fig. 1 the enforcement of technical scheme is described in detail:
With local side apparatus among the GPON, telemanagement is an example to terminal equipment ONU as OLT, the configuration data of each ONU produces according to system command, and step of the present invention is as follows:
Step 101:OLT divides into groups to ONU according to configuration data.Be about to the essentially identical ONU of configuration data and be divided in same group, as shown in Figure 2, ONU is divided into four groups, be respectively group 1, group 2, group 3 and organize 4, wherein, ONU1, ONU11, ONU12, ONU13, ONU14 dispose basic identical, are divided in group 1; ONU2, ONU21, ONU22, ONU23 dispose basic identical, are divided in group 2; ONU3, ONU31, ONU32 dispose basic identical, are divided in group 3; ONU4, ONU41, ONU42, ONU43, ONU44, ONU45 dispose basic identical, are divided in group 4.
Step 102:OLT selects an ONU as sample in every group, with the common configuration order it is carried out relevant configuration.Such as: in group 1, select ONU1 as sample, select ONU2 in the group 2, select ONU3 in the group 3, select ONU4 in the group 4 as sample as sample as sample.
Step 103: the configuration data of sample ONU is preserved into configuration script on OLT, and be appointed as shared configuration script, promptly the configuration script at sample ONU is provided with a shared mark.
The configuration script of ONU1 is as shown in table 1, altogether the capable configuration order of n.The configuration script of ONU2, ONU3 and ONU4 is different with a lot of configuration datas of ONU1, and still, configuration item class seemingly.
| Configuration order |
| Ethernet interface configuration order 1 |
| ... |
| Ethernet interface configuration order m |
| ... |
| GPON business configuration order 1 |
| ... |
| GPON business configuration order m |
| ... |
| Other configuration orders 1 |
| ... |
| Other configuration orders m |
Table 1
Step 104: finish the configuration script of whole ONU in proper order from organizing 1 beginning.
Can be undertaken by group 1 to group 4 orders.In every group, each ONU is similar to the configuration of sample ONU, and other ONU use and share configuration script, the i.e. configuration script of sample ONU in the designated groups.Similar for the ONU layoutprocedure except that sample ONU in each group, be that example describes with the layoutprocedure of organizing in 1 below, as shown in Figure 3:
Step 301: the ONU that does not dispose in the optional group according to the needs of concrete application, can determine whether this ONU (as ONU11) also needs to carry out other configurations except that sharing configuration script by the user; Carry out if desired and share configuration script configuration in addition, change step 302 over to; If no, change step 304 over to.
Step 302: its configuration different with ONU1 is set in the configuration script of this ONU, and promptly the distinctive configuration information of this ONU enters step 303 after finishing.
The shared configuration script of ONU1 is not enough to provide ONU11 needed configuration data, therefore, removes the configuration of ONU1, also needs to carry out extra configuration, i.e. the peculiar configuration of ONU11 uses the normal operations order to finish.
Step 303: the configuration script of on OLT, preserving this ONU.
With ONU11 is example, the configuration script of ONU11 is as shown in table 2, the shared profile of use ONU1 has shown the incidence relation of ONU11 and shared configuration script ONU1, the back is the distinctive configuration information of ONU11, if its distinctive configuration information has only one, so just have only two row configuration orders,, just have more multirow configuration order if more:
| Configuration order |
| Use the shared profile of ONU1 |
| The configuration information different with shared script |
| ... |
Table 2
Above configuration script is saved as the configuration script of ONU11, enter step 305.
Only preserve the incidence relation of this ONU and shared configuration script on the step 304:OLT, promptly under the configuration script of this ONU and the identical situation of shared configuration script, this ONU does not have the independent script of oneself to preserve;
Step 305: repeating step 301 to 304, until finishing group 1 configuration.
When ONU11, ONU12, ONU13, the ONU14 of group in 1 all dispose finish after, promptly finish group 1 configuration.
To group 4, adopt the process of similar step 301 to 305 for group 2, whole configuration script of ONU in finishing network.Like this,, just can be configured again each ONU, system is normally moved according to configuration script when system's power down or when restarting.
Supposing has 64 ONU under the OLT, each ONU configuration data need take the 1k byte, considers all identical situation (in most cases being such) of configuration data of all ONU.If do not adopt method of the present invention, need take the 64k byte; Adopt method of the present invention, then only need take slightly more than 1k bytes of memory space, saved nearly 64 times, ONU quantity more piece save space more is many more.In addition, adopt method of the present invention, in layoutprocedure, only need ONU of configuration, specify its configuration script for sharing configuration script then, other ONU is as long as use this configuration script, do not need remaining ONU configuration script is generated configuration item one by one, simplified the generation step of ONU configuration script.
If the ONU configuration data in the network under OLT is basic identical, so, just needn't divide into groups, the configuration script of directly selecting a sample ONU is as sharing configuration script, and other ONU uses should be shared configuration script, the incidence relation and the distinguishes data of preserving itself and appointed ONU get final product, and can save a lot of memory spaces equally.For the situation of needs groupings, the ONU of each group is configured also can be not according to the order of group 1 to group 4, but at random or other orders, as long as finish the configuration of all ONU successively.In addition, if be used for occasions such as system testing, in step 303, step 304, can not preserve the configuration script of other ONU as required, but check the configuration of whole ONU whether to satisfy the demand, adjust as required, like this, power down or when restarting, system can delete the configuration information of other ONU automatically.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
