Thus, when server a receive that terminal sends " carry out Jia 1 operating to browsing the number of times that ID=11 is the page,
And count the total degree of this page " service request (service parameter value is：When ID=11), server a judges that this business is joined
More than the service parameter value (ID=10) of setting, then corresponding server is current server (server a) to numerical value.
When server a receives another service request (such as business in the service request that terminal sends again
Parameter value is：When ID=8), server a judges that this service parameter value is not more than the service parameter value (ID=10) of setting, now
Service parameter value (ID=8) is carried out into modulo operation, i.e. 8/4=0 with the sum (sum is 4) of current line server, is obtained
The index of corresponding server is 0, and corresponding corresponding server is inquired about in current line server list for 0 further according to index,
Referring to table 1, determine that corresponding server is current server (server a).
Further, if terminal compartment is initiated comprising the industry that can synchronously perform to server a again after for a period of time
During the service request of parameter of being engaged in, if current online server is relatively changed before, judge and operating process be with embodiment one,
Will not be repeated here.
