<p>The present invention provides a method and an apparatus for hash detection among multiple tasks, wherein the method includes the following steps: A: before allocating labels, a protocol processing module first invokes a driving hash detection module in the bottom layer to check whether a label is available; the driving hash detection module performs an operation for writing the label into the hardware; if the writing operation fails, then it is known that a hash collision occurs, and the information that the label is not available is fed back to the protocol processing module; if the writing operation succeeds, then it is known that the label is available, and at the same time, the label with a pre-occupied status is added into a software table; B: the protocol processing module receives the feedback information from the driving hash detection module, if the feedback information indicates failure, then the method returns to the step A; and if the feedback information indicates success, then a service configuration is transmitted to a service driven processing module, and the service driven processing module judges whether the label is pre-occupied by the hardware, if so, deletes the label with the pre-occupied status and really writes the label into the hardware. The present invention can solve the problem that when multi-task operations are transmitted, hash collision occurs but can not be detected by the upper-layer configuration or protocol.</p> |
