Problems solved by technology

[0009] The distribution of network traffic may change dynamically, so setting a fixed value for the aging time uniformly cannot adapt to the change of network traffic distribution, and the flexibility is poor, resulting in a low hit rate of the flow table
In addition, the offloaded flow table space of the e-switch is limited, and a fixed aging time is set. If the flow table is full, high-traffic flow table entries cannot be offloaded.

Abstract

The present disclosure provides a flow table aging time adjustment method, device and storage medium, so as to achieve the purpose of improving the forwarding performance of an intelligent network card. This disclosure introduces the aging time information table of the offloading flow table to record and maintain the aging time and update timestamp of each flow, and set the aging time of the offloading flow table based on the aging time recorded in the aging time information table when the offloading flow table is delivered, through Dynamically monitor the unloading times and packet hit rate of the flow table, and independently learn and adjust the aging time of the flow in the aging time information table based on the preset algorithm according to the change of the network traffic distribution, thereby improving the hit rate of the flow table and improving the performance of the smart network card. Forwarding performance.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a method, device and storage medium for adjusting the aging time of a flow table. Background technique [0002] OVS (Openvswitch) is an open source virtual switch. It is also the switch with the largest deployment share in the cloud environment in the current market. It supports the Openflow protocol and OVSDB (Open vSwitch Database Management Protocol, Open Virtual Switch Database Management Protocol) protocol management. OVS consists of three important components: OVSDB-Server, OVS-vSwitchd and OVS kernel module. [0003] OVSDB-Server: The database service process of OVS, which is used to store the configuration information of the virtual switch (such as bridges, ports, etc.), and provides the OVSDB operation interface for the controller and OVS-vSwitchd. [0004] OVS-vSwitchd: The core component of OVS, responsible for saving and managing all flow tabl...
