Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of method and system for obtaining terminal attribute.
Background technology
As country is to the integration of three networks and the implementation energetically of bidirectional rebuilding, in user to many matchmakers such as voice, data and video
Under the driving of body integrated service demand, PON (Passive Optical Network)+EOC (Ethernet Over Coax's)
The network architecture is employed more and more extensive.Wherein, the EOC networks positioned at user side are mainly by local side apparatus and terminal device structure
Into, local side apparatus are based on EOC technical protocols stack and set up EOC network services by the EOC modules in EOC modules and terminal device,
Reach the purpose for transmitting Ethernet data on coax.Each local side apparatus can support multiple EOC modules, be generally divided into list
Mould, bimodulus and four mould local sides, and each local side EOC modules can the most 64 station terminal equipment of the second line of a couplet.
Under the application scenarios of multimode local side batch terminal, user is carried out in real time to the configuration information of all terminal devices
Inquiry is the huge time-consuming engineering of part, and the configuration information inquiry per station terminal equipment is required for being used as middle generation by local side apparatus
Reason carries out real-time query, and per station terminal, inquiry takes around 2 seconds every time for actual measurement, by taking four module local sides as an example, most full configurations 256
Terminal, substantially takes clock more than 8 points, consumes substantial amounts of query time, reduces the experience sense of user.Therefore it provides a kind of close
Manage and realize that the method for batch terminal quick obtaining attribute is imperative under simple multimode local side.
In the prior art for the method that batch terminal quick obtaining attribute is realized under multimode local side, mainly there is following several
The mode of kind：
1st, inquired about by single thread, database caches mode, specifically：User trigger inquiry request, on local side apparatus with
Single thread mode searches for local side apparatus, while successively each module of local side apparatus and its all terminal devices of the second line of a couplet with confidence
Breath is obtained together, and is stored in database, user's query configuration information from database again.The maximum shortcoming of this kind of technical scheme
It is that, in the case where terminal device quantity is larger, the search equipment consuming time is long when inquiring about first, poor user experience.Meanwhile,
New terminal needs global search again and updates the data storehouse in the case of reaching the standard grade.In addition, the introducing of database increased system answering
Miscellaneous degree and development management cost.
2nd, inquired about by multithreading, database caches mode, specifically：
Compared with such scheme, this kind of technical scheme introduces multithreading, while local side apparatus are searched for, for every
The configuration information of individual local side module and its second line of a couplet terminal device inquires about a newly-built thread, and such scheme is performed in new thread
Operation.This kind of technical scheme can improve overall search efficiency, but there is also corresponding deficiency simultaneously：First, multithreading draws
The lock management difficulty that the load and cross-thread mutual exclusion for entering increased system cause；Secondly, the switching scheduling of cross-thread is difficult to ensure that
New terminal is reached the standard grade can be retrieved and in real-time update to database in time, and causing user's needs to carry out repeatedly refreshing just can be with
Read complete terminal attributive information.
3rd, the EOC NMSs based on Simple Network Management Protocol, as shown in figure 1, what this kind of technical scheme was taken
Method is：When new terminal device accesses described EOC networks, new terminal device sends one based on letter to local side apparatus
The essential information broadcast packet of single NMP, after local side apparatus receive the broadcast packet, by the basic letter of new terminal device
Breath is stored in local side memory module, and generates new terminal topology figure by network topological diagram generation module, and by new terminal topology
Figure is shown by display module.The technical scheme can be good at solving new terminal and reach the standard grade the problem that rescans of introducing, shorten
The read access time of terminal equipment configuration information in EOC networks.But, it is to need modification existing the drawbacks of the technical scheme is maximum
The software architecture of terminal, increased the complexity of system architecture, while greatly reducing the compatibility of system.
