 Load balancing processing method and system

 The invention belongs to the field of network communication, and in particular relates to a load balancing processing method and system. Background technique

 The conference system is either a star structure or a tree structure, which is more suitable for small and medium-sized conferences. Because, when faced with a large-scale conference of millions and millions of levels, all communication data in the star-shaped conference system is concentrated on one server for corresponding processing, which results in the central server being overloaded and extremely inefficient. The tree-structured conference system has a problem of hierarchically setting up the server, but there is a problem that the organization of the conference between the lower-level and the upper-level is complicated, and in general, the upper-level server does not have the data of the lower-level personnel, which may cause problems such as failure to communicate normally. Furthermore, regardless of the video conferencing server or other useful servers, there is a problem that the user needs to know the IP address or domain name of the server that is authorized to log in in advance. In addition, before each meeting, you also need to manually authorize the server to which each participant is logged in, and announce the IP of the server that each person has obtained the login authorization before the meeting. As a result, it is easy to appear one minute before the meeting. Participants are on the phone to consult the IP of the server that they are authorized to log in to.

The evaluation value calculation function is set, and the evaluation values are respectively obtained and compared, and the target conference control center is determined according to the comparison result.

 Wherein, the evaluation value calculation function is: F (x, y, z) = f (x) + f (y) + f (z); f (x) is the distance coefficient function, "x" represents the distance; f (y Represents the bandwidth factor function, "y" represents the bandwidth; f (z) represents the load factor function, and "z" represents the "number of loads that have been connected to its two-way communication."

The other data processing devices respectively feed back the assistance response message; wherein the assistance response message carries the processing capability information; wherein the processing capability information includes: the number of receivables that can be received. The data processing device determines, according to the assistance response message, the target data processing device according to the selection policy, and the target data processing device processes the participation request information of the participant; wherein the selection policy is a selection feedback receivable load number The largest data processing device.

Then the data processing device A triggers the negotiation mechanism to the data processing device B and the data processing respectively. Device G sends assistance request information;

 The data processing device B feeds back the assistance response message, where the assistance response message carries information that the number of receivable loads is two;

 The data processing device G feeds back the assistance response message, where the assistance response message carries information that the number of receivable loads is five;

 The data processing device A selects the data processing device G that can receive the largest number of loads to process the participation request information of the participant.

It can be seen that: Xinxiang Conference Control Center evaluation value = 2 (distance coefficient) +3 (bandwidth factor) +2 (load factor) = 7

 Xinyang Conference Control Center evaluation value is =1 (distance coefficient) +2 (bandwidth factor) +5 (load factor)

=8

 Therefore, it is known that the corresponding conference control center (ie, the Xinyang Conference Control Center) having a large evaluation value is selected as the target conference control center.

 Step 203: The target conference control center determines the target data processing device according to the participation request information of the participant end, and the table 4: the identity level (the identity level of the user at the conference end), the load number interval, and the data processing device comparison table. The target data processing device processes the participation request information of the participant. Table 4: Identity level and load number interval, data processing equipment comparison table

 If the user's identity level of the participant is high, the data processing device 1 is determined as the target data processing device according to the identity level and the load interval and the data processing device comparison table;
