Problems solved by technology
However, due to differences in the preamble, frame gap, and packet length of the output data, using bps as the rate limit unit cannot intuitively reflect the forwarding performance of the virtual machine in many application scenarios
For example, the forwarding performance with a bandwidth data of 9.7Gbps (1.19 million pps) and a packet length of 1024Bytes, compared to the forwarding performance with a bandwidth data of 2.06G (1.74 million pps) and a packet length of 128Bytes, directly comparing the bps bandwidth is obviously ineffective. reasonable

The invention provides a virtual machine speed limiting method and device, electronic equipment and a readable storage medium, and the method comprises the steps: receiving a configuration request for the QOS of a target virtual machine, the configuration request comprises a data packet forwarding speed limiting rule, and the data packet forwarding speed limiting rule comprises a data packet forwarding speed threshold; and according to the configuration request, a meter speed limit table entry and a speed limit flow table are added to the integrated network bridge, and the meter speed limit table entry and the speed limit flow table are used for controlling the speed of a data packet flowing into the target virtual machine or a data packet flowing out of the target virtual machine to be smaller than the data packet forwarding speed threshold value according to a data packet forwarding speed limit rule. According to the method, the speed is limited by adopting packet / second (pps) as a speed limiting unit, the forwarding performance of the virtual machine can be accurately represented, the speed limiting mode can be applied to various types of virtual machines, such as a virtual machine with a network card data forwarding path in a kernel mode, a DPDK high-performance virtual machine with a network card data forwarding path in a user mode and the like, and the application mode is wider.
Description
technical field [0001] The present application relates to the technical field of cloud computing, and in particular to a virtual machine speed limiting method, device, electronic equipment and readable storage medium. Background technique [0002] As the current open source cloud computing management platform project, OpenStack has received extensive attention and application from the industry. [0003] Since the service quality of the virtualized network directly affects the service quality of users in the cloud computing environment, the quality of service (QOS for short) guarantee capability of the virtualized network has become an important basic service capability in the cloud computing system. [0004] In the existing OpenStack environment, the QOS guarantee of various types of virtual machines usually adopts bandwidth speed limit, and the speed limit unit is generally bps (bits / sec). However, due to differences in the preamble, frame gap, and packet length of the out...
