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 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 backup LB node. On...

Abstract

The invention discloses a high available realizing method of a load balancing service. The method is applied to load balancing nodes in a load balancing service cluster of Openstack. The method comprises the steps as follows: switching a second LB node used as any backup LB node of the load balancing service cluster as a main LB node after LBaas agent on the first LB node used as the main LB node of the load balancing service cluster is failed, configuring a virtual host name of the load balancing service cluster as a self virtual host name, and starting the LBaas agent; transmitting a synchronous request message carried with the virtual host name to a control node; receiving a synchronous response message returned by the control node, and creating each load balancer according to configuration information of each load balancer carried by the synchronous response message and port numbers which correspond to each load balancer one by one.

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 L4-L7 services, such as load balancing services (Loadbalance as a service, LBaas), etc. Users Through these services, more applications can be deployed 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 an...
