Detailed description of the invention
Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail. Although shown in accompanying drawingExemplary embodiment of the present disclosure, but should be appreciated that and can realize the disclosure with various forms and should be byHere the embodiment setting forth limits. On the contrary, providing these embodiment is in order more thoroughly to understand thisOpen, and can be by the those skilled in the art that conveys to complete the scope of the present disclosure.
As shown in Figure 3, be the main step of the method for Gi fire wall load sharing networking in embodiments of the inventionRapid flow chart, comprises the steps:
Step S101, the mobile terminal that reception gateway general grouping service wireless support node GGSN sendsUpstream data.
Step S102, is distributed to multiple Gi fire walls by described upstream data according to predefined distribution ratio.
In the present embodiment, first obtain the concurrent connection number of the each Gi fire wall in multiple Gi fire walls,Then the concurrent connection number of Gi fire wall and the corresponding relation of distribution ratio are set in advance definite eachThe distribution ratio of Gi fire wall, finally ought receive gateway general grouping service wireless support node GGSN and send outWhen the upstream data of the mobile terminal sending, by this upstream data according to the concurrent company of predefined Gi fire wallConnect number and be distributed to multiple Gi fire walls with the corresponding relation of distribution ratio, make multiple Gi fire wall sharedsFrom the network address translation business of the upstream data of mobile terminal.
Below this is described for example.
As shown in Figure 4, be the distribution ratio list of multiple Gi fire walls in embodiments of the invention.
The quantity of supposing Gi fire wall is 3, and the name of first Gi fire wall is called F1, and address is10.1.1.111, maximum concurrent connection number is 100; The name of second Gi fire wall is called F2, and address is10.2.1.222, maximum concurrent connection number is that the name of 100, the three Gi fire walls is called F3, and address is10.3.1.333, maximum concurrent connection number is 200. Obtain the maximum concurrent connection number of F1, F2, F3, calculateGo out the ratio F1:F2:F3=1:1:2 of the maximum concurrent connection number of F1, F2, F3, determine thus each GiThe ratio of the upstream data that fire wall is distributed to, and to the concurrent connection number of Gi fire wall and distribution ratioCorresponding relation is made setting. When receiving moving of gateway general grouping service wireless support node GGSN transmissionWhen the upstream data of moving terminal, by this upstream data according to the concurrent company of predefined described Gi fire wallConnect number and be distributed to corresponding Gi fire wall with the corresponding relation of distribution ratio. The numerical value of supposing upstream data is 1,The ratio that F1 is distributed to is that the ratio that 25%, F2 is distributed to is that the ratio that 25%, F3 is distributed to is 50%.
It should be noted that at this, the number of fire wall is multiple, does not specifically limit the number of fire wall.
As shown in Figure 5, for upstream data being divided according to predefined distribution ratio in embodiments of the inventionSend to multiple Gi fire walls flow chart of steps afterwards, comprise the steps:
Step S201, the IP address of record move terminal, receives the GGSN of the upstream data of mobile terminalIdentification information and the corresponding relation of multiple Gi fire walls address, and generate business chain according to described corresponding relation.
In the present embodiment, when the upstream data of mobile terminal that GGSN is sent is according to predefined pointAfter the ratio of sending out is distributed to multiple Gi fire walls, according to the flowing through channel of upstream data, record sends upper line numberAccording to mobile terminal IP address, receive upstream data GGSN identification information and receive upper line numberAccording to the corresponding relation of multiple Gi fire walls address, finally generate business chain according to this corresponding relation.
Below this is described for example.
As shown in Figure 6, the business chained list for generating in embodiments of the invention.
By finding out in form, generate altogether two business chained lists, enter according to the title of mobile terminal IDRow name, is respectively U1 business chain and U2 business chain. In the generative process of U1 business chain, IP groundLocation is that the mobile terminal of the 10.1.1.1 GGSN that is 10.1.1.11 by upstream data through address is respectively according in advanceIf ratio is distributed to three fire walls such as F1, F2, F3, according to the flowing through channel of this upstream data, according to movingThe identification information of IP address 10.1.1.1, the GGSN of moving terminal (comprises ID G1 and the GGSN of GGSNAddress 10.1.1.11) and multiple Gi fire walls address (being respectively 10.1.1.111,10.2.1.222,10.3.1.333)Corresponding relation generate U1 business chain. In the generative process of U2 business chain, IP address is 10.2.1.2The GGSN that mobile terminal is 10.2.1.22 by upstream data through address respectively according to preset ratio be distributed to F1,Three fire walls such as F2, F3, according to the flowing through channel of this upstream data, according to the IP address of mobile terminal10.2.1.2, the identification information of GGSN (comprising the ID G2 of GGSN and the address 10.2.1.22 of GGSN)And the corresponding relation of multiple Gi fire walls address (being respectively 10.1.1.111,10.2.1.222,10.3.1.333)Generate U2 business chain.
It should be noted that at this, the business chain number in business chained list has more than and is confined to two of U1 and U2Business chain, meanwhile, ID and multiple fire wall that the ID of a GGSN can corresponding multiple mobile terminals,This is not made to concrete restriction.
Step S202, forwards follow-up upstream data and the downlink data of described mobile terminal by described business chain.
In the present embodiment, when after the business of generation chained list, the upstream data of same mobile terminal and lower line numberForward according to equal business chain at the place, IP address by this mobile terminal in business chained list.
Step S203, judges that described business chain forwards follow-up upstream data and the downlink data of described mobile terminalTime whether exceed predetermined threshold.
In the present embodiment, when follow-up upstream data and the downlink data of mobile terminal turn according to business chainWhile sending out, in order to make full use of fire wall resource, need to be to follow-up upstream data and the downlink data of mobile terminalForwarding time and predetermined threshold compare.
Step S204, if described business chain forwards the follow-up upstream data of described mobile terminal and downlink dataTime does not exceed predetermined threshold, the follow-up upstream data of described mobile terminal and downlink data is passed through to instituteStating business chain forwards.
In the present embodiment, if business chain forwards the follow-up upstream data of described mobile terminal and downlink dataTime does not exceed predetermined threshold, illustrates that repeating process is normal, by the follow-up upstream data of mobile terminalForward by described business chain with downlink data.
Step S205, if described business chain forwards the follow-up upstream data of described mobile terminal and downlink dataTime exceedes predetermined threshold, deletes described business chain.
In the present embodiment, if the follow-up upstream data of business chain transmitting mobile terminal and the time of downlink dataExceed predetermined threshold, in order to discharge fire wall resource, directly deleted the place, IP address of this mobile terminalBusiness chain.
