Abstract

The invention discloses a network abnormal event sensing method and system. The network abnormal event sensing method comprises the following steps: inserting INT detection headers into all messages,sampling the messages, and labeling the INT detection headers of sampling messages; INT related operation is carried out on the message, the INT related operation comprises adding INT metadata to themessage, and the INT metadata records state information when the switch processes the message and is added behind the INT detection header; Screening a message containing the INT metadata of the at least one hop switch, and copying and uploading the message; Carrying out preliminary summarization on the uploaded message to generate a sub-event; And further summarizing the generated sub-events to obtain a final summarization of the events. According to the network abnormal event sensing method and system, full-amount, accurate and real-time network events are obtained, and the method and systemare used for fault diagnosis, topology assessment and the like.

Description

technical field [0001] The present invention relates to the field of Internet information technology, in particular to a network abnormal event perception method and system capable of fully and accurately capturing statistical information and events in physical network devices. Background technique [0002] The data center network carries many applications such as cloud computing, e-commerce, and new retail, and the performance of its network services greatly affects the indicators of service delivery. However, there are many uncertainties in the service of the data center network. For example, software bugs, hardware failures, misoperations in operation and maintenance, etc., these events can potentially seriously affect business performance. However, traditional data center network management focuses more on network management and control from top to bottom, that is, making network behavior conform to the logic and policies defined by the upper layer. The data-based feed...
