Service processing method and device

A service processing method, applied to a system comprising a first distributed node and at least two second distributed nodes, wherein the first distributed node communicates with a controller using the at least two second distributed nodes, and wherein the service processing method comprises:

• processing, by the controller, a second operation request received by the controller from the first distributed node using a third distributed node in the at least two second distributed nodes, wherein the second operation request comprises a first service object and a second identification code;
• receiving, by the controller, a first operation request and a first identification code from the first distributed node using a second distributed node in the at least two second distributed nodes, wherein the first operation request comprises the first service object, wherein the first identification code identifies a processing sequence of the first operation request relative to other operation requests obtained separately from the first operation request, and wherein the processing sequence identifies an order to process the other operation requests that include a same service object;
• determining, by the controller according to a preset rule, the first identification code, and the second identification code, whether the first operation request needs to be processed;
• processing, by the controller, the first operation request when it is determined that the first operation request is sent after the second operation request;
• and
• skip processing, by the controller, the first operation request when it is determined that the first operation request is sent before the second operation request.

A first distributed node, comprising:

• a processor configured to:
• obtain a first operation request comprising a first service object;
• allocate a first identification code to the first operation request according to a preset rule, wherein the first identification code identifies a processing sequence of the first operation request relative to other operation requests obtained separately from the first operation request, and wherein the processing sequence identifies an order to process the other operation requests that include a same service object;
• obtain a second operation request comprising a second service object;
• allocate a second identification code to the second operation request according to the preset rule, wherein the second identification code identifies a processing sequence of the second operation request for the second service object;
• determine that the second operation request is dependent upon the first operation request;
• and
• set the first identification code as a dependent code of the second operation request, wherein the dependent code of the second operation request enables the controller to process the second operation request after processing the first operation request;
• and
• a transmitter coupled to the processor and configured to:
• send the first operation request and the first identification code to a controller using a second distributed node in at least two second distributed nodes, wherein the preset rule and the first identification code enable the controller to determine whether the first operation request needs to be processed;
• and
• send the second operation request, the second identification code, and the dependent code of the second operation request to the controller using a third distributed node in the at least two second distributed nodes.

A controller, comprising:

• a receiver configured to receive a first operation request and a first identification code from a first distributed node using a second distributed node in at least two second distributed nodes, wherein the first operation request comprises a first service object, wherein the first identification code identifies a processing sequence of the first operation request relative to other operation requests obtained separately from the first operation request, and wherein the processing sequence identifies an order to process the other operation requests that include a same service object;
• and
• a processor coupled to the receiver and configured to:
• process a second operation request received by the controller from the first distributed node using a third distributed node in the at least two second distributed nodes, wherein the second operation request comprises the first service object and a second identification code;
• determine, according to a preset rule, the first identification code, and the second identification code, whether the first operation request needs to be processed;
• process the first operation request when it is determined that the first operation request is sent after the second operation request;
• and
• skip processing the first operation request when it is determined that the first operation request is sent before the second operation request.
