Embodiment Construction

[0024] In the prior art, the control node can manage multiple LB nodes that start LBaas agents, and dispatch the user's request to create a load balancer to the LBaas agent of a certain LB node through a scheduling algorithm, and the LBaas agent started on each LB node can be Generate and configure multiple load balancers. Therefore, the LBaas agent deployed on the LB node is a single point of failure. If no improvement is made, when a certain LB node goes down, the LBaas agent on the LB node will fail, which will lead to the failure of the LBaas agent created by the LB node. Each load balancer is also unavailable, and the traffic using the load balancing service on the LB node will be interrupted.

[0025] Therefore, the technical solution of the present invention proposes a high-availability solution for implementing load balancing services, and creates a load balancing service cluster. The load balancing service cluster is composed of a master LB node and at least one backu...

Abstract

The invention discloses a method for realizing high availability of load balancing service, which is applied to the load balancing node in the load balancing service cluster of Openstack, and the method includes: LBaas agent on the first LB node as the main LB node of the load balancing service cluster After failure, the second LB node that is any standby LB node of the load balancing service cluster is switched to the primary LB node, configure the virtual host name of the load balancing service cluster as its own virtual host name, and start the LBaas agent; Send a synchronous request message with the same name to the control node; receive a synchronous response message from the control node; create each load balancer according to the configuration information of each load balancer carried in the synchronous response message, and the port numbers corresponding to each load balancer. device.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for realizing high availability of load balancing services. Background technique [0002] Openstack is a cloud computing platform that can help users build and manage public clouds, private clouds, etc. Neutron is a network component in Openstack, which provides virtualization of network functions. It can not only provide flexible network connections for tenants, but also provide advanced services from L4 to L7, such as Load balance as a service (LBaas). These services can deploy more applications in their own cloud environment. [0003] The realization of LBaas service is roughly divided into two parts, one part runs on the control node of openstack, which provides users with application programming interface (Application Programming Interface, API) access, database addition, deletion, modification and query, and scheduling of user requests;...
