Embodiment Construction

[0027] The technical solutions in the preferred embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0028] The core of the method and system for realizing energy-saving statistics in the Ethernet chip disclosed by the present invention is to use SRAM and calendar (circular traversal table) to replace counters for statistical counting. The statistical information stored in SRAM includes count value, event state, and cumulative time value of statistical interval.

[0029] Such as figure 2 As shown, the Calendar is implemented with a configuration register group, which is controlled by the Calendar controller, and each register is written with the number of the port. The register can be flexibly configured according to the number and usage of the port, and will not be limited to the switch. Physical port form. At the same time, you can configure the Calendar to achieve dif...

Abstract

The invention discloses a method for realizing energy-saving statistics in an Ethernet switching chip and a system for realizing energy-saving statistics in the Ethernet switching chip. By means of an embedded SRAM (static random access memory), a calendar controller and a calendar register set are used for controlling and refreshing statistics in the SRAM of a selected register port, wherein the statistics include trigger times and trigger time values of the selected register port, and when the statistics in the SRAM exceed a certain threshold value, the SRAM reports to a CPU (central processing unit) to read the statistics. The method is capable of accurately making statistics on energy-saving information of the energy efficient Ethernet, the area of the chip can be saved, cost and power consumption can be reduced, and different physical port shapes of exchangers can be flexibly supported.

Description

technical field [0001] The invention relates to computer network technology, in particular to a method and system for realizing Energy Efficient Ethernet (Energy Efficient Ethernet) energy-saving statistics in an Ethernet switch chip. Background technique [0002] With the continuous growth of the capacity of Ethernet switching chips and the complexity of application scenarios, the number of MAC (Media Access Control, Media Access Control) ports on a single chip has also increased significantly, resulting in an increase in power consumption of the chip. The Energy Efficient Ethernet protocol has been formulated in the IEEE802.3az standard. This protocol determines whether to close the port with low load according to the load degree of the MAC receiving and sending end in the statistical chip, so as to achieve the effect of energy saving. Therefore, in order to effectively display the energy-saving effect of the MAC port, an accurate and efficient load statistics function mo...
