Embodiment Construction

[0059] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0060] Since in actual network equipment, the transmission of a certain data flow is often bursty, to record the relevant statistical information of the data flow will inevitably lead to frequent access of the statistics module to the external memory, thus sharing an external memory for multiple applications. The memory brings difficulties, so reducing the number of visits of the statistics module to the above-mentioned external memory is the purpose of the present invention.

[0061] Such as figure 2 As shown, it is a functional block diagram of the ...

Abstract

The present invention relates to a method and device for storing statistical information. The device includes an external memory, a QDR interface module, a shift buffer module, and a statistical module; Its address in the external memory, and store the obtained address in the local FIFO. When the local FIFO has an output address, judge whether there is a matching address in the shift buffer module, and if so, shift the above Add 1 to the statistical value of the statistical entry corresponding to the above address in the cache module, otherwise, read the original statistical value of the above statistical entry from the above address of the external memory, add 1 to the original statistical value, and add 1 to the above statistical entry The obtained statistical value and its address in the above-mentioned external memory are stored in the above-mentioned shift buffer module. The invention reduces the number of device IOs used and reduces the difficulty of single board layout and wiring.

Description

technical field [0001] The invention relates to the fields of communication and data storage, in particular to a statistical information storage method and device. Background technique [0002] With the continuous improvement of the performance of high-end switches and the continuous enrichment of data communication services, network equipment has an increasing demand for the storage capacity of statistical information; and the development of various new services has made the storage resources inside the chip more precious. Therefore, currently most of them adopt the mode of external RAM (Random Access Memory) to increase the storage space. This method can not only meet the high performance and high bandwidth requirements, but also store statistical information of larger capacity. [0003] At the same time, with the rapid development of Ethernet technology, the proportion of Ethernet networking in network construction is gradually increasing, and the network scale is also ex...
