Embodiment Construction

[0046] The present invention provides a dynamic detection method for micro-engine abnormality, comprising the following steps: (1) periodically detecting the abnormal operation of the micro-engine; (2) recording the state of the abnormal micro-engine; and giving an alarm to the abnormal operation of the micro-engine; (3) Carry out pre-set processing for the special situation where the micro-engine is abnormal.

[0047] In step (1), the anomaly detection of the micro-engine provides the following three detailed methods:

[0048] a. Judging by the increasing trend of the received packet count of the interface chip and the increasing trend of the total processed packet count of the micro-engine, that is, if the received packet count of the hardware is continuously increasing, but the total received packet count of the micro-engine is no longer increasing , it can be determined that the micro-engine is running abnormally.

[0049] b. Judging by checking whether the total count se...

Abstract

The method includes following steps: (1) periodic sensing and determining whether operation of micro engine is abnormal; if yes, then going to step (2); if no, then the method is ended; (2) recording and warning abnormal state of micro engine; (3) carrying out process setup in advance on the abnormal micro engine. The invention can detect abnormal state of micro engine in time and rapidly as well as reduce interrupting time brought by appeared problem of micro engine greatly.

Description

technical field [0001] The invention relates to data network communication technology, in particular to a method for detecting and processing abnormal operation of a micro-engine of a network processor. Background technique [0002] At present, most of the data products of major communication equipment companies at home and abroad use network processors to realize various routing and forwarding services, especially in mid-to-high-end routers, switches and other products, due to the continuous superposition of services, the gradual increase of functional modules , the method of using hardware logic such as FPGA is far less flexible than the implementation of network processors, but because the implementation of network processors is actually a software method, the abnormal situation in actual operation is higher than that of FPGA and other hardware implementations. [0003] In addition, the data products implemented in the form of network processors have two relatively indepe...
