The invention discloses a service concurrent
access control method and a service concurrent
access control device. The method comprises the following steps that: S401, a
service system receives service requests; S402, whether the number of the service requests achieves the maximum concurrent number to which the
service system can respond is judged, if the number of the service requests achieves the maximum concurrence number, the step S403 is executed, or else S404 is executed; S403, information that the
service system is busy is fed back to a service requiring part; S404, whether the service requests need to
queue up or not is judged according to the emergency degree of the service requests and the
processing channel number of the service
system, if the service requests need to
queue up, S405 is executed, or else S406 is executed, and if the
processing channel is used up, S407 is executed; S405, the service requests
queue up and wait for being awakened; S406, the service requests are processed; and S407,
processing channel use-up information is fed back. The method and the device control the service request concurrence according to demands, and at the same time ensures that access requests of different nodes or node domains are served in accordance with desired weight
modes, and moreover emergency channels are provided and at the same time emergency service requests obtain the in-time service, so that the precision and the efficiency in service concurrence control are improved.
