The routing between the general step (with no name) and While Loop contains logic that corresponds with the loop condition.
通用步骤（没有任何名称）和 While 循环之间的路由包含与循环条件对应的逻辑。

The routing to Process Task has the logical opposite, so when the loop condition is false, this route will be taken instead.
到流程任务的路由包含相反的逻辑，因此当循环条件为false时，将改为采用此路由。

A new deflection routing scheme is proposed to overcome the drawback of the existing deflection routing scheme, such as inability to handle node failure and suffering from routingloop.
