The invention discloses a kind of main/standby switching method; Had in the existing active/standby link switchover technology to solve, can only could be switched when breaking down, thereby can not be adapted to the problem of the application scenarios of complicacy main with server; Its workflow sketch map is as shown in Figure 2, comprising:
Step S1, the main operating state with server of detection are to judge whether to satisfy preset active and standby switching condition; In the prior art, only break down with server, when promptly heartbeat stops main; Just can carry out the switching of main/slave link; In order to adapt to complicated application scenarios, make active and standby switching more flexible, in this programme; Be provided with active and standby switching condition in advance, and judge whether said master satisfies said preset active and standby switching condition with server.Wherein, said active and standby switching condition is following a kind of: switch when satisfying preset load, switch by the time of setting, or switch under other situations; For example, when said active and standby switching condition is to switch when satisfying preset load, need be the CPU of server in advance then; Or load value of other component settings; When said master should load with server is satisfied, explain that then said master bears higher load with server, should carry out active and standby switching; When said active and standby switching condition when switching by the time of setting; When said master satisfies the time of said setting with the time of server work; Explain that then said master has worked the long period with server,, should carry out active and standby switching in order to improve main useful life with server.But be not limited to above-mentioned active and standby switching condition; Under different application requirements, other active and standby switching condition can be set, simultaneously; For the switching between the application server of realizing main usefulness and the subsequent use application server, need to judge mainly whether satisfy preset active and standby switching condition with server.
Step S2, when needs carry out active and standby switching; Produce modify instruction; And said modify instruction transferred to domain name server (DNS) Server; So that domain name server DNS Server is according to said modify instruction, the domain name of storing among the corresponding modification domain name server DNS Server and the corresponding relation of IP address are realized active and standby switching.
Through the disclosed main/standby switching method of such scheme; When needs carry out active and standby switching, can be through the domain name of storing in the corresponding modification name server and the corresponding relation of IP address, so that CSCF is after domain name server DNS Server sends the domain name mapping request; Obtain the IP address of former standby server; Impel CSCF to distribute route, thereby realize the switching of active/standby server, because said active and standby switching condition is to be provided with according to different application conditions to amended IP address corresponding server; Make the disclosed main/standby switching method of this programme can be applicable to different application scenes, improved the flexibility of active/standby link switchover.
In step S2; Said modify instruction comprises: first modify instruction or second modify instruction; Said first modify instruction is used to improve the priority of the IP address of the standby server corresponding with domain name, and said second modify instruction is used to delete the main IP address with server corresponding with domain name.Under normal operating condition; In domain name server DNS Server; Generally store domain name, with the corresponding priority in domain name corresponding IP address and said IP address, said main IP address with server is in higher priority, the IP address of said standby server is in lower priority; At said CSCF when said DNS Server sends the domain name mapping request; Can obtain and be in higher priority, promptly main IP address with server, and with route assignment extremely said master use server.When needs carry out active and standby switching; Said first modify instruction is used to improve the priority of said standby server IP address; Thereby after making said CSCF send the domain name mapping request; Obtain the IP address of said subsequent use service, and with route assignment to said standby server, to realize the switching of main/slave link.In addition; Said second modify instruction is used to delete the main IP address with server corresponding with domain name, thereby after making said CSCF send the domain name mapping request, can only obtain the IP address of said subsequent use service; And with route assignment to said standby server, to realize the switching of main/slave link.
For example, set the master and use server to be AS-1, standby server is AS-2; Its IP address is respectively 10.125.12.30 and 10.125.23.30; Before not carrying out active and standby switching, the IP address of AS-1 has higher priority, and the two common domain name is as.example.com.When CSCF CSCF will visit as.example.com; Need to send domain name mapping request DNS query to domain name server (DNS) Server; The domain name server can return the IP address that is in higher priority to CSCF, that is to say, the domain name server can be with the IP address of AS-1; 10.125.12.30 be sent to CSCF; Said CSCF can send call request INVITE information to said master with server A S-1 according to the IP address that receives, and foundation and said main with the data transmission link between the server A S-1.
When needs carry out active and standby switching; Then produce modify instruction; And said modify instruction transferred to domain name server (DNS) Server; Domain name server DNS Server is according to said modify instruction, the domain name of storing among the corresponding modification domain name server DNS Server and the corresponding relation of IP address.Said modify instruction is: improve first modify instruction of the priority of the standby server IP address corresponding with domain name, or, delete second modify instruction of the master corresponding with the IP address of server with domain name.When said modify instruction was first modify instruction, then the domain name server can improve the priority of the IP address of standby server AS-2, so that its priority is higher than the IP address of said AS-1.When said modify instruction is second modify instruction, then delete the IP address of the said AS-1 that stores in the domain name server.Through said first modify instruction or said second modify instruction that receives; Said CSCF is after sending domain name mapping request DNS query to the domain name server; Can get access to the IP address 10.125.23.30 of said standby server AS-2, said CSCF can send call request INVITE information to said standby server AS-2 according to the IP address that receives; And the data transmission link between foundation and the said standby server AS-2, thereby realize active and standby switching.
Wherein, the situation that need carry out active and standby switching comprises two kinds of situation at least, and a kind of situation is that main operating state with server satisfies said preset active and standby switching condition; Another kind of situation is, and is main with the said active and standby switching condition of server unmet, but said master also need carry out active and standby switching when breaking down with server.For example; Set said master and after satisfying the time of setting, carry out active and standby switching with server; When the said main operating time with server is satisfied the time of setting, perhaps time of operating time unmet setting, but fault has taken place with server in said master; All to produce said modify instruction under the both of these case, to realize active and standby switching.
