Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Following example of the present invention are for wide area network terminal management system as shown in Figure 1, this wide area network terminal management system includes load-balancing device LB, ACS cluster and user side equipment CPE, this ACS cluster includes at least two ACS, this LB is for dispatching the CPE service message sent to ACS, realize the load balancing of ACS cluster, this ACS is for according to the CPE service message sent, issuing the business such as configuration, diagnosis or the upgrading relevant to this CPE.In order to avoid ACS is when receiving the request of CPE every time, from DB (DataBase, data base), all obtain configuration data corresponding to this CPE, cause data base's bottleneck, ACS can access the configuration data of the CPE of this ACS by buffer memory in advance, it is therefore desirable to the fixing binding of CPE and ACS.
In order to those skilled in the art can fast understanding technical scheme, below the relational language that the present invention relates to is illustrated:
OSI (OpenSystemInterconnection, open system interconnection net reference model): it is the method for designing of a kind of framework, it is logically divided into procotol 7 layers, is followed successively by from the bottom to top: physical layer, data link layer, Internet, transport layer, session layer, expression layer, application layer.Wherein, the parsing of message is resolved to top order successively only in the bottom.
Wherein, resolve the CPE service message sent to Internet, IP (InternetProtocol, the Internet protocol) address of this CPE can be got.IP address is network is each CPE logical address distributed, and when CPE starts every time, the IP address that network is this CPE distribution is likely to difference；Resolve the CPE service message sent to application layer, unique mark of this CPE can be got.
Unique mark of CPE: it can be the MAC (MediaAccessControl of CPE, media access control layer) address, can also being the equipment Serial Number (SerialNumber) of CPE, wherein, unique mark of CPE be included in the application layer of this CPE service message sent.
The embodiment of the present invention provides a kind of method that user side equipment and configuration service device are mutual, as in figure 2 it is shown, the method includes:
S201, LB receive the CPE service message sent.
Wherein, this LB can be a configuration service device ACS, say, that there is an independent ACS in the ACS cluster of wide area network terminal management system and is used as load balancing.It addition, CPE is when dispatching from the factory, the ACSURL (UniformResourceLocator, uniform resource locator) of default configuration is the URL of this LB, and so, service message upon actuation, is sent to this LB by this CPE according to the URL of acquiescence.
S202, this LB resolve this service message, obtain the IP address of this CPE.
S203, when this LB is cached with the corresponding relation of the IP address of this CPE and configuration service device ACS, this LB determines that this corresponding relation is in default buffer memory effect duration, this service message is sent to this ACS, wherein, the IP address of this CPE and the corresponding relation of this ACS are that this LB sets up with the mapping relations of this ACS according to unique mark of this CPE.
It should be noted that this LB storage has unique mark of CPE and the mapping relations of ACS, wherein, these mapping relations can be pre-set according to the quantity of CPE and the quantity of ACS by user.It addition, by preceding description it can be seen that unique mark of this CPE can be the MAC Address of this CPE, it is also possible to for the equipment Serial Number of this CPE.
Specifically, this LB, when the corresponding relation of the uncached IP address having this CPE and ACS, obtains unique mark of this CPE, the unique mark according to this CPE, and uniquely identifying of CPE determine the IP address of the ACS corresponding with this CPE, this CPE of buffer memory and the corresponding relation of this ACS with the mapping relations of ACS.
In a kind of possible implementation of the embodiment of the present invention, this LB is while the IP address of this CPE of buffer memory with the corresponding relation of this ACS, the cache-time mark of this corresponding relation of buffer memory, this cache-time mark can be this LB system time when this corresponding relation of buffer memory.
So, this LB determines that this corresponding relation was in default buffer memory effect duration and is specifically as follows, it is determined that the cache-time mark of this corresponding relation, with the time difference of current time less than or equal to this buffer memory effect duration preset.Wherein, this buffer memory effect duration can by user previously according to requirements set, such as 30 seconds.
Further, this LB is when being cached with the corresponding relation of the IP address of this CPE and an ACS, it is determined that the IP address of this CPE and the corresponding relation of an ACS are not in the buffer memory effect duration preset, and obtain unique mark of this CPE；Unique according to this CPE identifies, and uniquely identifying of CPE determines twoth ACS corresponding with this CPE with the mapping relations of ACS；Oneth ACS and the 2nd ACS is the arbitrary ACS in wide area network terminal management system；The IP address of this CPE and the corresponding relation of the 2nd ACS is utilized to update the IP address of this CPE and the corresponding relation of an ACS.
What deserves to be explained is, the IP address of this CPE is variable when each starting up, therefore, if LB is that CPE assigns ACS according only to the mapping relations of IP address Yu ACS, it is impossible to ensure the fixing binding of CPE and ACS, say, that, after twice start of this CPE, the ACS of access is likely to difference.But, in embodiments of the present invention, unique mapping relations identified with ACS that the IP address of CPE and the corresponding relation of ACS are according to CPE are set up, unique mark of CPE is constant, so, LB, at the default effective after date of buffer memory, all can set up the IP address of CPE and the corresponding relation of ACS according to unique mark of CPE with the mapping relations of ACS, it is ensured that can be linked into identical ACS after each starting up of this CPE again.
And, within default buffer memory effect duration, this LB, after receiving this CPE service message sent, obtains the IP address of this CPE, from the above-mentioned explanation to OSI, LB obtains the IP address of CPE only need to carry out 3 layers of parsing to service message, in compared to existing technology, LB receives this CPE service message sent every time, all needs to carry out 7 layers and resolves the unique mark obtaining this CPE, the embodiment of the present invention alleviates the burden of LB, it is to avoid performance bottleneck occurs in this LB.
The technical scheme of a kind of method that the embodiment of the present invention provides in order to enable those skilled in the art to be more clearly understood that user side equipment and configuration service device are mutual, below by specific embodiment, technical scheme provided by the invention is described in detail, as it is shown on figure 3, include:
S301, LB receive the CPE service message sent.
S302, this LB are resolved to the Internet of this service message, obtain the IP address of this CPE.
By the aforementioned introduction to OSI, Internet belongs to the 3rd layer of service message.
S303, this LB determine whether the corresponding relation of IP address and the ACS being cached with this CPE.
Wherein, as it is shown in figure 1, an ACS is the arbitrary ACS in this wide area network terminal management system.
Further, if the corresponding relation of the uncached IP address having this CPE of this LB and an ACS, step S304 to step SS307 is performed；If this LB is cached with the IP address of this CPE and the corresponding relation of an ACS, perform step S308.
S304, this LB are resolved to the application layer of this service message, obtain unique mark of this CPE.
By the aforementioned introduction to OSI, application layer belongs to the 7th layer of service message.
S305, this LB identify according to the unique of this CPE, and uniquely identifying of CPE determines an ACS corresponding for this CPE with the mapping relations of ACS.
Alternatively, these mapping relations are that the unique mark to CPE adopts the cryptographic Hash of hash algorithm acquisition and the corresponding relation of ACS, then this LB calculates the cryptographic Hash of this MAC Address, inquires about this mapping relations, it is determined that the ACS that this cryptographic Hash is corresponding.
Illustratively, before system start-up, user presets the radix of hash algorithm in LB according to the quantity of CPE, such as, the quantity of this CPE is 1,000,000, then can set the radix of this hash algorithm as 10,000, say, that the span of the uniquely identified cryptographic Hash of all CPE is one to one ten thousand；And according to the quantity of ACS to cryptographic Hash segmentation, for instance, the quantity of this ACS is 4, then cryptographic Hash can be divided into four sections: 1-2500,2501-5000,5001-7500,7501-10000, wherein, and the corresponding ACS of each Hash section.Therefore, this LB, after the uniquely identified cryptographic Hash obtaining this CPE, inquires about the Hash section residing for this cryptographic Hash, and it is this CPE ACS assigned that ACS corresponding to this Hash section is this LB.
S306, this LB this CPE of buffer memory the corresponding relation of IP address and an ACS, and the cache-time mark of this corresponding relation.
Wherein, this cache-time mark can be this LB system time when this corresponding relation of buffer memory.
This service message is sent to an ACS by S307, this LB.
Whether S308, this LB determine that the cache-time of the IP address of this CPE and the corresponding relation of an ACS identifies, with the time difference of current time less than or equal to default buffer memory effect duration.
Wherein, this buffer memory effect duration can by user previously according to requirements set, and such as 30 seconds, this was not limited by the present invention.
Further, if the cache-time that this LB determines the IP address of this CPE and the corresponding relation of an ACS identifies, with the time difference of current time less than or equal to default buffer memory effect duration, then perform step S309；If the cache-time that this LB determines the IP address of this CPE and the corresponding relation of an ACS identifies, with the time difference of current time more than this buffer memory effect duration preset, then perform step S310 to step S313.
This service message is sent to an ACS by S309, this LB.
S310, this LB are resolved to the application layer of this service message, obtain unique mark of this CPE.
S311, this LB identify according to the unique of this CPE, and uniquely identifying of CPE determines the 2nd corresponding for this CPE ACS with the mapping relations of ACS.
It should be noted that the 2nd ACS is the arbitrary ACS in wide area network terminal management system.Further, if the IP address after this starting up of this CPE is identical with the IP address after last time starting up, then a 2nd ACS and ACS is same ACS.
S312, this LB utilize the IP address of this CPE and the corresponding relation of the 2nd ACS to update the IP address of this CPE and the corresponding relation of an ACS, utilize the cache-time mark of the IP address with cache-time mark this CPE of renewal of the corresponding relation of the 2nd ACS, the IP address of this CPE and the corresponding relation of an ACS.
This service message is sent to the 2nd ACS by S313, this LB.
What deserves to be explained is, if this LB is cached with the IP address of this CPE and the corresponding relation of an ACS, and the cache-time mark of this corresponding relation, with the time difference of current time more than default buffer memory effect duration, then an ACS was this IP address before this buffer memory effect duration preset, the ACS that affiliated CPE is corresponding.If the CPE that this IP address is belonging to before this buffer memory effect duration preset is identical with the CPE that this sends service message, then an ACS and the 2nd ACS is same ACS.
By above-mentioned steps it can be seen that LB is at the default effective after date of buffer memory, all again the IP address of CPE and the corresponding relation of ACS can be set up according to unique mark of CPE with the mapping relations of ACS, it is ensured that after each starting up of this CPE, identical ACS can be linked into.It should be noted that this buffer memory effect duration preset should be less than the interval between twice start of CPE, otherwise, twice start of this CPE is likely to access different ACS.Therefore, user according to the practical situation at CPE available machine time interval, can set rational buffer memory effect duration.
So, within default buffer memory effect duration, this LB, after receiving this CPE service message sent, obtains the IP address of this CPE, from the above-mentioned explanation to OSI, LB obtains the IP address of CPE only need to carry out 3 layers of parsing to service message, in compared to existing technology, LB receives this CPE service message sent every time, all needs to carry out 7 layers and resolves the unique mark obtaining this CPE, the embodiment of the present invention alleviates the burden of LB, it is to avoid performance bottleneck occurs in this LB.
Additionally, according to existing TR069 agreement, ACS is after receiving the CPE service message sent, it is capable of identify that whether this CPE belongs to this ACS, for not being the CPE belonging to this ACS, this ACS sends the URL of self to this CPE, and this CPE is after receiving this ACS URL sent, the URL of this CPE LB stored is replaced by the URL utilizing this ACS, and the URL according to this ACS directly sends service message to this ACS.But, of a great variety due to CPE, some CPE support the amendment of URL, some CPE do not support the amendment of URL, therefore, in a kind of possible implementation of the embodiment of the present invention, for not supporting that the URL CPE revised, this type of CPE still send service message to LB, LB it is scheduling；For supporting that the CPE, this type of CPE of URL amendment according to existing procedure after the URL using ACS replaces the URL of LB, can directly transmit service message to ACS.So, this LB only receives the service message not supporting that the URL CPE revised sends, and further mitigates the burden of this LB.
It should be noted that, for said method embodiment, in order to be briefly described, therefore it is all expressed as a series of combination of actions, but those skilled in the art should know, the present invention is not by the restriction of described sequence of movement, secondly, those skilled in the art also should know, embodiment described in this description belongs to preferred embodiment, necessary to involved action and the module not necessarily present invention.
