Problems solved by technology

LVS has a variety of working modes such as DR, NAT, FULLNAT, etc. Among them, DR data packets are forwarded on the second layer. This mode has the best performance, but the DR mode needs to configure the back-end REALSERVER, such as configuring VIP on the back-end server. Information, and configure ARP corresponding processing, etc., resulting in the implementation of the DR mode of the LVS network load balancer in the openstack public cloud environment has great limitations

Embodiment Construction

[0024] The OpenStack cloud computing platform consists of two main modules: Nova and Swift. The former is a virtual server deployment and business computing module developed by NASA; the latter is a distributed cloud storage module developed by Rackspace. The two can be used together or separately. . OpenStack supports almost all types of cloud environments. The goal of the project is to provide a cloud computing management platform that is simple to implement, scalable, rich, and standardized.

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0026] The present invention provides an application method of an LVS load balancer under the cloud. Aiming at the openstack public cloud platform, the load balancing configuration is per...

Abstract

The invention discloses an application method of an LVS load balancer under cloud, and relates to the field of cloud computing virtual services. The method is used for an openstack public cloud platform. The method comprises the following steps: performing load balancing configuration through an LVS load balancing virtual node, forwarding a data packet to a back-end server, receiving an ovs flow table through the back-end server, processing a corresponding source IP and a corresponding destination IP through the ovs flow table, and modifying a corresponding mac address and a corresponding portto complete correct sending of the data packet; according to the invention, the DR mode of the LVS can be realized without modifying any configuration of the back-end server in a public cloud environment, and the load balancing efficiency is improved, so that the operation resources are saved, and the operation cost is reduced.

Description

technical field [0001] The invention discloses an application method, relates to the field of cloud computing virtual services, in particular to an application method of an LVS load balancer under the cloud. Background technique [0002] Cloud computing provides users with extremely convenient resource usage and flexible resource expansion capabilities through the virtualization abstraction of various physical resources such as computing, network, and storage. Load balancing is a basic function of cloud products, which has relatively high requirements on data packet forwarding performance, and LVS is convenient for forwarding at layer 4, so LVS has become the first choice for cloud load balancing. LVS, also known as Linux virtual server, is a relatively mature open source project, which implements functions through the ipvs module, and mainly works on the INPUT chain of netfilter. LVS has a variety of working modes such as DR, NAT, FULLNAT, etc. Among them, DR data packets ...
