The invention relates to the field of traffic limiting control of an electricity transaction system access request, and particularly relates to an electricity transaction system request managing and traffic limiting method based on a token bucket algorithm. The method comprises the following steps: (1) creating and managing a traffic token bucket: performing creation and management of the traffictoken bucket of each module according to a traffic request characteristic, a micro-service node distribution condition and the like of the each module of an electricity transaction system; (2) implementing the token bucket algorithm of a single node: implementing the token bucket algorithm for a single module and the single node; and (3) transferring a traffic between nodes of a same module: if the traffic of one node reaches to a limit, automatically transferring a request traffic that is not processed to other nodes of the same module. According to the method, based on a principle of the token bucket algorithm, the traffic management, traffic transfer and traffic limitation under a micro-service architecture are implemented, and thus the electricity transaction system is effectively guaranteed to operate securely and reliably.
