Step 3, client and server successful connection and reach the waiting time after, client is according to initial heart cycle value
Send m fixed cycle heartbeat；
Step 4, when send m fixed cycle heartbeat it is all successful when, record server response number of success is q, wherein institute
The initial value for stating q is m；
Step 5 is calculated new heart beat cycle value by the first algorithm as the T times heart beat cycle value, while recorded the T times
Heart beat cycle value, and after reaching the waiting time, client sends the T times heartbeat, and wherein the initial value of T is (m+1), described etc.
It is equal to T-1 heart beat cycle value to the time, wherein first algorithm are as follows:
Y=X*log102
In formula, y is the T time heart beat cycle value, x > 10, and the value of x the T times greater than the T-1 times；
Step 6, after client sends the T time heartbeat server and respond successfully, record server respond it is successfully secondary
Number q=q+1；
Step 7, when server response number of success q be not up to preset value k when, be arranged T=T+1, return step 5.
Further, client records client network environment and accesses before client establishes communication connection with server
Server is supplied to the interface of client, and server returns to initial heart cycle value by inquiry database, to client.
Further, when server response number of success q reaches preset value k, client no longer carries out new calculating
Record, it is fixed to reach the heartbeat sent when preset value k using server response number of success when client sends heartbeat.
