Fading_factor is adjusting step value, for smoothly restraining, prevents from fluctuating excessive；Inst_num be and the interface service
The total quantity of all service servers of device connection；Queue_length is default queue length.Default queue length can root
The processing number of requests generated according to all clients in historical experience within the unit interval determines, and is set with above-mentioned random number
Fixed number amount is the relation increased in proportion.If default queue length is excessive, then the processing that client generates in the unit interval is asked
Quantity is much smaller than default queue length, so as to which part random number can be caused to be not used, so that load balancing effect becomes
Difference；If default queue length is too small, the processing number of requests that client generates in the unit interval is much larger than default queue length,
So as to because final weighted value is integer the value finally calculated be caused to lose precision, and then load balancing may be influenced
Effect.It can be seen that if default queue length is more close with the processing number of requests that client generates within the unit interval, bear
It is higher to carry balanced effect.S230, the weighted value by least two service servers, are sent to client, to indicate the visitor
Family end determines corresponding service server according to the weighted value for the processing request that client generates, and the processing is asked
It is sent to the service server.
Fig. 5 is the flow chart of the load-balancing method for another server that the embodiment of the present invention three provides.Referring to Fig. 5,
In practical applications, the load information of interface server timing acquisition reflection service server processing capacity and machine resources letter
Breath, and corresponding weighted value is calculated based on above-mentioned load information and machine resources information；Client is periodically from interface server
Middle synchronous service server list and corresponding weighted value, and flow is matched according to corresponding weighted value, it is negative to realize
It carries balanced.
Meanwhile by the load balancing of the load-balancing method of above-mentioned server provided in this embodiment and existing server
Knowable to method is compared：The load-balancing method of existing server is to generate processing request by client, and is sent to and connects
The processing received is requested assignment to each service server according to load balancing, thus may be used by mouth server, interface server
