Embodiment Construction
[0030] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.
[0031] The main framework of the present invention includes: (1) an internal model used to realize the network flow processing process (2) an adaptive frequency adjustment method based on the internal model.
[0032] The internal model of the network flow processing process is the basis for the implementation of the present invention. The internal model simulates the classic producer-consumer process, that is, the network interface receives data packets from the link, puts them into the tail of the queue of the first-in-first-out queue (FIFO queue), and at the same time, the processor receives data packets from the head of the queue. Get the packet for processing and forward the packet. This process widely exists in various network devices. Based on this, t...

The invention provides an adaptive frequency modulation energy-saving method for a multi-core multi-thread intrusion detection device, and is mainly applicable to network equipment (or a computer system) for supporting frequency conversion during operation. The method includes following steps: 1) predicting the flow change condition in a future period according to the current flow condition; 2) enumerating all possible frequency operation sequences in the future period, and obtaining state data of the current processor, such as equipment operation frequency, the length of a buffer area of the current network data packet, and the occupied condition of the buffer area of the current network data packet; 3) sending the state data of the processor, the flow change condition in the future period, and the frequency operation sequences to an internal model, performing simulation of each frequency operation sequence by the internal model, and selecting the optimal frequency operation frequency; and 4) applying the optimal frequency operation sequence to a real processor.
Description
technical field [0001] The invention relates to the technical field of network security, in particular to an adaptive frequency modulation energy-saving method of a multi-core and multi-thread intrusion detection device. Background technique [0002] With the continuous increase of Internet bandwidth and the continuous complexity of network security, more and more intrusion detection devices (IDS) are deployed on the network to detect intrusion behavior and take blocking actions. However, network traffic is quite uncertain, and the average utilization rate of a large number of network links is less than 30%. In order to ensure that burst traffic can be handled, redundant devices have to be deployed. These devices run at full speed and consume a lot of power resources. For this reason, it becomes a very necessary technology to consider designing a method to reduce the power consumption of intrusion detection equipment. [0003] At present, energy saving methods for network ...
