Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
The flow chart of the method for the realization Web conference drift that provides for preferred embodiment according to the present invention shown in Figure 1.As shown in Figure 1, the method for the realization Web conference drift that preferred embodiment of the present invention provides comprises step 101 ~ 104.
In step 101, after the conference parameters information of carrying in the Web conference request that domain name resolution server receives and the parsing user sends, said Web conference request is sent to the Region control server.In this, conference parameters information comprises meeting number, participant's area information and address information.Wherein, participant's area information refers to the area information that people with a part in a conference person distributes.
Particularly, when the user initiates Web conference, set the meeting number, participant's area information of said Web conference after, the Web conference request is sent to domain name resolution server.After domain name resolution server receives the Web conference request, through resolving the conference parameters information acquisition user's addresses information (for example, IP address) of carrying in the Web conference request.For example; If being the user P of 202.91.251.148, the IP address initiates Web conference; And setting the meeting number is 200 people; Participant's area information is Suzhou and Hangzhou, and then can to obtain the IP address through the Web conference request of resolving user P and sending be 202.91.251.148 to domain name resolution server, and corresponding zone, above-mentioned IP address is Hangzhou.Then, domain name resolution server is forwarded to this Web conference request on the Region control server in Hangzhou.In other words, domain name resolution server is forwarded to corresponding Region control server through the address information of resolving in the conference parameters information with the Web conference request.
In step 102; The conference parameters information of carrying in the said Web conference request of said Region control server parses; Confirm conference type, and judge according to meeting load threshold table whether the active conference number of said conference type in the affiliated area surpasses corresponding maximum meeting and count threshold value.In this, said conference type comprises general meeting, one's respective area convention and trans-regional convention.The differentiation standard example of said conference type is as shown in table 1.Yet the present invention does not limit this.In practical application, can set the kind and the differentiation standard of conference type as required.
Table 1
In this, corresponding three load-balanced servers of each Region control server, the corresponding conference type of load-balanced server.In other words, the number of load-balanced server can be confirmed according to conference type.Yet the present invention does not limit this.Then; The Web conference request of still sending with user P in the step 101 is an example, after the Region control server in Hangzhou receives this Web conference request, resolves the conference parameters information of this Web conference request; Obtain meeting number 200 people; Participant's area information is Suzhou and Hangzhou, can know that according to the above-mentioned conference type table of comparisons this Web conference belongs to general meeting in view of the above.
In present embodiment, the meeting load threshold table of each region server storage one's respective area.The meeting load threshold table of each region server storage comprises that threshold value and active conference number are counted in the corresponding maximum meeting of different conference type in the one's respective area.Wherein, the maximum meeting in each regional meeting load threshold table is counted threshold value and can be confirmed according to actual conditions.The present invention does not limit this.
For example, the meeting load threshold table example of the Region control server stores in area, Hangzhou is as shown in table 2.
Conference type Threshold value (unit: the field) is counted in maximum meeting The active conference number (unit :)
General meeting 1000 658
The one's respective area convention 300 47
Trans-regional convention 500 89
Table 2
In present embodiment, the Region control server is according to the active conference number in the Web conference request real-time update meeting load threshold table that receives.If the Region control server judges that the active conference number that obtains said conference type in the affiliated area does not surpass corresponding maximum meeting and counts threshold value, then the Region control server is sent to the Web conference request and conference type corresponding load equalization server.Load-balanced server is sent to the corresponding communication server with said Web conference request after receiving the Web conference request, and the said communication server is handled said Web conference request.For example; If this Web conference request is " user a sends text message to user b "; After the communication server receives this request; At first to distributed cache server inquiring user b on which communication server, and then send request to the communication server at user b place, ask this communication server to transmit text message and give user b.In this, the information in all communication servers all can be synchronously to distributed cache server.The communication server is realized trans-regional information interaction through distributed cache server.So, improved communication efficiency.
In step 103, if surpass, then said Region control server will surpass corresponding maximum meeting and count the Region control server parameter information that the conference parameters information of the said Web conference request of threshold value reaches except that affiliated area and be sent to the domain name resolution server.Wherein, the Region control server lookup obtains the Region control server parameter information except that affiliated area.Region control server parameter information except that affiliated area comprises address information.
