Abstract

A service processing method, a network device and a service processing system are disclosed. The method includes: determining whether a frequency of a service request initiated by a user exceeds a set value according to user information carried in the received service request; discarding the service request, if the frequency of the service request exceeds the set value; and transmitting the service request, if the frequency of the service request does not exceed the set value. Determining whether the frequency of the service request initiated by the user exceeds the set value comprises: inquiring whether there exists a control table corresponding to user information and service content carried in the service request; determining whether the frequency of the service request exceeds the set value according to the control table, if there exists the control table; and establishing the control table of the service request according to the user information and the service content, if there does not exist the control table, and transmitting the service request.

transmitting the service request.

3. The service processing method of claim 1, wherein the user information is an MAC address, a user name or an IP address.

4. The service processing method of claim 1 further comprising:

updating the timing of a last service request and the number of times of the service request in the control table after discarding the service request or transmitting the service request.

5. The service processing method of claim 4, further comprising:

deleting the control table of the service request if no service request transmitted from the user is received in a predetermined time after the timing of the last service request.

6. The service processing method of claim 1, further comprising:

determining whether the service request is supported, after a network device receives the service request;

performing the process of determining whether the frequency at which the user initiates the service request exceeds the set value according to the user information carried in the received service request, if the service request is supported;

forwarding the service request to another network device that supports the service request, if the service request is not supported; and

receiving, by the another network device, the service request and then performing the step of determining whether the frequency at which the user initiates the service request exceeds the set value according to the user information carried in the received service request.

7. The service processing method of claim 1, further comprising:

determining whether the number of the service requests currently processed by a server is less than a preset value according to an address of the server that processes the service request carried in the service request, after the network device receives the service request;

performing the process of determining whether the frequency at which the user initiates the service request, exceeds the set value according to the user information carried in the received service request, if the number of the service requests currently processed by the server is less than the preset value; and

discarding the service request, if the number of the service requests currently processed by the server is not less than the preset value.

8. The service processing method of claim 1, wherein the process of transmitting the service request comprises:

determining, by the network device, whether operation status of a server that is currently processing the service request is normal;

transmitting the service request to the server, if the operation status of the server that is currently processing the service request is normal; and

transmitting the service request to a backup server both which and the server serve as a backup of each other, if the operation status of the server that is currently processing the service request is not normal;

or, the process of transmitting the service request comprises;

transmitting, by the network device, the service request to a server with a smallest load among a plurality of servers that can process the service request.

9. A network device, comprising:

a receiving module, configured to receive a service request;

a control table storage module, configured to store a control table that includes user information, service content of a user request, a starting timing of the service request, the timing of a last request, the number of times of the request and a set value;

an inquiry module, configured to inquire in the control table storage module whether there exists the control table corresponding to user information and a service content carried in the received service request;

a frequency comparing module, configured to determine whether the frequency of the service request exceeds the set value according to the control table;

a suppressing module, configured to discard a service request having a frequency greater than the set value; and

a transmitting module, configured to transmit a service request having a frequency not greater than the set value.

10. The network device of claim 9, further comprising a control table establishing module, configured to establish the control table of the service request, and to record service content of the service request, starting timing, the timing of the last request, the number of times of the request and the set value in the control table.

11. The network device of claim 9, further comprising an updating module, configured to update the timing of the last service request and the number of times of the service request in the control table.

12. The network device of claim 9, further comprising a deleting module, configured to delete the control table of the service request if no service request transmitted from the user is received in a predetermined time after the timing of the last service request.

13. The network device of claim 9, further comprising an authentication module, configured to determine whether the service request is supported, and the network device forwards the service request to another network device that supports the service request if the service request is not supported.

14. The network device of claim 9, further comprising:

a number comparing module, configured to;

determine whether the number of service requests currently processed by the server is less than a preset value according to an address of the server mat processes the service request carried in the service request;

transmit the service request to the inquiry module if the number of service requests currently processed by the server is less than the preset value; and

transmit the service request to the suppressing module if the number of service requests currently processed by the server is not less than the preset value.

15. The network device of claim 9, further comprising a status detection module, configured to:
