Description

Technical Field

[0001] The present invention belongs to the technical field of container orchestration of rack-mounted devices, and specifically relates to a container orchestration system and method based on rack-mounted routers and switches. Background Art

[0002] With the continuous expansion of the network scale and the rapid change of business requirements, traditional fixed-function rack-mounted routers are not flexible enough to cope with new network services and application deployments. Container orchestration technology allows different network function modules to be quickly deployed and updated on routers, enabling on-demand expansion to meet dynamic network requirements. The current sonic (Software for Open Networking in the Cloud) provides a complete set of solutions, enabling users to freely customize the functions of router and switch devices. And container orchestration tools provide methods for resource management of router software containers. However, the sonic system does not yet support a container orchestration management solution for both the master control layer and the forwarding layer on rack-mounted devices.

[0003] Existing container orchestration tools are difficult to meet the function of container orchestration for rack-mounted devices. Container orchestration tools that support cluster orchestration can manage multiple nodes, but the nodes need to download container images first before container orchestration management can be carried out. It is more applied to large servers or data centers. It is not suitable to use container cluster orchestration tools on a specific device such as a rack-mounted router.

[0004] Existing container orchestration technologies such as kubernetes, etc., can achieve distributed container deployment and orchestration, seemingly applicable to simultaneous orchestration and deployment of the forwarding plane and the control plane of rack-mounted devices. However, in actual operation, kubernetes suites need to be installed on the master control plane and the forwarding plane to make them become a node of kubernetes before they can be managed. This causes a great loss to the performance of the forwarding plane, and the forwarding plane should be used as much as possible for high-speed data forwarding. Kubernetes is more applied to scenarios such as data centers and cloud computing. Servers in these scenarios have high performance and are easy to expand, and can support kubernetes suites and can be flexibly expanded when the computing power is insufficient. Summary of the Invention

[0005] The purpose of the present invention is to provide a container orchestration system and method based on rack-mounted routers and switches for the above deficiencies in the prior art, so as to solve the problem that the existing support for container orchestration management cannot be carried out simultaneously on the master control layer and the forwarding layer of rack-mounted devices.
