Embodiment

[0065] This embodiment is an embodiment of a method for dynamically adjusting the aging frequency of hardware entries implemented based on the above-mentioned device. First, set the cumulative statistics field of the number of consecutive hits and the activity field in the software descriptor of each entry in the hardware chip table, respectively It is used to count the number of consecutive hits of the table item and save the calculated liveness value; when performing dynamic adjustment of the aging frequency, it reads the statistics field of the number of consecutive hits and the liveness field in the software descriptor of the table item value, and adjust the aging frequency of active entries according to the corresponding logic, such as figure 2 As shown, the method flow includes the following steps:

[0066] 1. Read the software descriptor of the entry:

[0067] In this step, when the system software polls the hardware chip table, it first reads the values ​​of the numb...

Abstract

The invention relates to the field of data communication, which discloses a method, device and computer storage medium for dynamically adjusting the aging frequency of hardware entries, which solves the problem of traversing all entries that need to be aged in the traditional hardware entry aging scheme, which is very difficult for hardware operations. Frequent, takes up a lot of system overhead, and aging efficiency is low. The device in the present invention includes: an active entry identification module, used to identify active entries in the hardware chip table, and an activity calculation module, used to calculate the activity of the active entry according to the activity calculation rule; processing, It is used to adjust the aging frequency of the active entry according to the activity of the active entry. In addition, the invention also discloses a corresponding method for dynamically adjusting the aging frequency of hardware entries, which is suitable for fast forwarding processing of hardware chips.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method, device and computer storage medium for dynamically adjusting the aging frequency of hardware entries. Background technique [0002] With the continuous development of communication technology, the demand for forwarding capability in the market is also getting higher and higher. It has become the industry norm for equipment manufacturers to use dedicated hardware chips to achieve fast data lookup and forwarding. Due to the very limited resources of hardware chip table items, in order to make full use of the feature of fast table lookup and forwarding of hardware chips, it is necessary to regularly clean up the inactive table items of the hardware chip, that is, to age the inactive table items to improve the performance of the hardware chip table items. effective utilization. [0003] For the aging processing of hardware entries, the industry generally uses hardware sel...
