Abstract

The invention relates to an OpenStack-based routing high availability method and system. The method comprises: the network state information sent by each Harouter-agent is received at a preset time interval; according to the network state information sent by the agent, it is judged whether there is a network card fault or not, and in response to the judgement that there is a network card fault, anisolation request is sent to the Harouter-agent, the application program interface of the Neutorn module is called to delete the original virtual router and recreate the virtual router on the other available network nodes. The invention periodically inquires the network card status of the physical machine where the virtual router is located according to the preset time interval, and when the physical network card fails or the physical network fails, the virtual router is moved to other available network nodes, so as to ensure the normal operation of the cloud host.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, the present invention relates to an OpenStack-based routing high-availability method and system. Background technique [0002] A router, also known as a gateway device, is used to connect multiple logically separated networks and is the core of the entire network. The so-called logical network represents a single network or a subnet. When data is transferred from one subnet to another, it can be done through the router's routing function. Therefore, routers have the function of judging network addresses and selecting IP paths. Routers can establish flexible connections in a multi-network interconnection environment, and can connect various subnets through completely different data packets and media access methods. A router can receive information from the source station or other routers, and is an interconnected device at the network layer. [0003] In the case of ...
