Abstract
Official abstract text for this publication.
The disclosure discloses a method and a system for detecting an abnormality of a network processor. The method comprises the following steps: an abnormality detection operation code is added into an execution flow of each thread in a network processor, and the network processor sets a flag bit corresponding to a current thread in an abnormality protection flag data area in a shared memory to a first flag when executing the abnormality detection operation code in the current thread; and when a period of a timer is expire, a coprocessor detects all the flag bits in the abnormality protection flag data area in the shared memory, determines that a thread corresponding to a flag bit which is not the first flag is abnormal when detecting that not all the flag bits are the first flag, and sets all the flag bits to a second flag when detecting that all the flag bits are the first flag. Through the disclosure, the abnormality of a thread can be detected timely and efficiently, so that the failure detection capability of the network device using the network processor as a core unit at run time is improved without influencing the forwarding performance and service processing flow of the network processor.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for detecting an abnormality of a network processor, comprising: adding an abnormality detection operation code into an execution flow of each thread in a network processor, and setting a flag bit corresponding to a current thread in an abnormality protection flag data area in a shared memory to a first flag by the network processor when executing the abnormality detection operation code in the current thread; and when a period of a timer is expir…
