The present invention, by the Various types of data of home gateway carries out classification storage and management, has been reduced as far as read-write
The number of times of flash and define the regional extent of read-write flash, it is to avoid business datum read-write is abnormal and loses, and has saved fortune
Battalion's cost.
This programme mainly includes following two aspect:
One, the data within home gateway are classified, and by original data storage at flash raw partition.
Different demarcation according to the reading and writing data attribute within home gateway and purposes is following five big classes:
1, survey data are produced: factory is in order to check the quality of each components and parts of home gateway, at each components and parts of home gateway
After being completed, adding excessive data on home gateway, these data only help to differentiate bad home gateway and unit's device
Part, after home gateway dispatches from the factory, these data will no longer function, and also will not be loaded.
2, creation data: the unique information to each home gateway typing when plant produced, including the MAC of home gateway
The information such as address, the series number of home gateway, wireless access title and password, these data are once produced would not be again
It is modified.
3, default data: the configuration parameter of home gateway has a lot, but most of configuration parameter has its initial default value,
These part data, as an initial data part for home gateway, can not be modified.
4, pre-configuration data: according to the property requirements in each area, the data to the amendment of being customized of default data, one
As for meeting the individual demand in each area, after home gateway dispatches from the factory, these data can not be modified.
5, user data: the business datum that operator issues for user, and the individual character that home gateway is done by user
The amendment changed, the data that operator issues are typically the most relevant to business, as broadband dial account and password, voice account information and
The information such as IPTV service, the data side of user's amendment overweights function and the characteristic etc. of home gateway self.
In the flash raw partition of home gateway, it is respectively divided the regional extent of each storage for above five class data, with
Time, according to the characteristic of Various types of data, produce survey data, creation data, default data and pre-configuration data and be read-only, home gateway
The most only read this four classes data, will not be to its operation of modifying, therefore, these data areas of flash raw partition are external
Can only read and can not write.User data is in addition to can read, it is also possible to be modified, therefore the number of users of flash raw partition
Not only can read but also can write according to region, so when reading and writing a certain data, only corresponding data region be performed read-write operation,
Reduce the regional extent of read-write flash raw partition.
The above-mentioned five class data of home gateway are stored directly in flash raw partition, so can not in file system
Seeing, user and upper level applications can not directly access, and can only call specified interface by software inhouse and be written and read.
Control to promote the safety of system by home gateway internal data being carried out classification storage and read-write properties,
After user data is destroyed, can be with quick recovery system.
Two, the read-write to Various types of data uses caching mechanism, after home gateway powers on, according to loading requirements of process part
During data, just these part data are loaded into corresponding caching from flash raw partition, then are loaded into internal memory from caching, straight during reading
Connect and obtain from internal memory, during amendment, directly revise the data in corresponding caching and internal memory, after operation to be modified completes, property again
Data are postponed in the flash raw partition being stored back to write correspondence, thus reduce the number of times of direct read/write flash raw partition.
Below in conjunction with specification drawings and specific embodiments, the present invention is described in detail.
The method embodiments providing the classification storage management of a kind of home gateway service data, as it is shown in figure 1, this
Invention is five big classes according to the different demarcation of reading and writing data attribute home gateway within and purposes: product survey data, creation data,
Default data, pre-configuration data and user data etc., at the space size that flash raw partition takies according to Various types of data, divide
Go out five fixed area, deposit this five classes data respectively.The physical layer interface start-stop address by Various types of data, directly operates

It is changeless data, therefore, the operation of these four classes data on flash raw partition is only only had read operation, does not has
Write operation, thus above four class data are from flash raw partition to caching, from being cached to internal memory, are unidirectional arrow, only read
Extract operation, does not has write back operations.
And user data can be typically administered remotely platform and terminal web page is modified, it is ensured that home gateway exists
After power-off, user data is not lost, then user data must be able to be written back in the user data of flash raw partition, therefore, and figure
Being four-headed arrow between the user data in the user data of flash raw partition and caching in 1, it is also double for caching between internal memory
To arrow, can read and can write.
The data loading flow process of whole home gateway may be considered and is loaded into caching from flash raw partition, then from caching
It is loaded into internal memory, directly obtains from internal memory during reading, during data modification, the data in directly amendment correspondence caching and internal memory, treat
After write operation completes, data are postponed in the flash raw partition being stored back to write correspondence by property again, thus reduce direct read/write
The number of times of flash raw partition.
Product, after factory's burning sheet completes, is surveyed data, default data and pre-configuration data and is written to flash by home gateway
