Address resolution method, cloud platform and medium

Abstract

The invention discloses an address resolution method, a cloud platform and a medium. The method comprises the steps that virtual machine information is issued to an address resolution server through a control plane in the cloud platform; the virtual machine information comprises a mapping relation between IP addresses and MAC addresses of all virtual machines in the cloud platform and current position information; obtaining an ARP request message sent by a virtual machine in a local node through an address resolution agent deployed in each computing node, packaging the ARP request message into an address resolution request message, and sending the address resolution request message to an address resolution server; an address resolution server analyzes an MAC address corresponding to an IP address requested to be analyzed and current position information based on virtual machine information to obtain an analyzed MAC address and target position information, packages an address resolution response message based on the analyzed MAC address and the target position information, and returns the address resolution response message to a corresponding address resolution agent. The performance of the control plane can be improved, and thus the user experience is improved.

Description

technical field [0001] The present application relates to the field of cloud computing, and in particular, to an address resolution method, a cloud platform and a medium. Background technique [0002] Large-scale public cloud platforms have extremely high requirements on the performance of the entire system, including control plane performance and data plane performance. At present, the virtual network implementation mechanism based on the fully distributed routing architecture realizes the local routing and forwarding of east-west three-layer traffic by dispersing VPC (Virtual Private Cloud, virtual private cloud) virtual routers to each computing node. In order to improve the data plane performance of the system, however, the full address resolution of the virtual network and the full address mapping of the instances in the VPC in the virtual router introduced on the computing nodes have brought enormous pressure to the control plane of the system, resulting in the control...

At present, based on the virtual network implementation mechanism of the fully distributed routing architecture, by distributing the VPC (Virtual Private Cloud, virtual private cloud) virtual router to each computing node, the local routing and forwarding of east-west three-layer traffic is realized. In order to improve the performance of the data plane of the system, however, the full address resolution of the virtual network introduced on the computing nodes and the full address mapping of the instances in the VPC in the virtual router have brought huge pressure to the control plane of the system, causing the control plane The CPU usage of the node soars and cannot be operated normally, which seriously affects the user experience
