A method for realizing high-speed distributed routing between computing nodes in a data center

Abstract

The present invention provides a method for realizing high-speed distributed routing between computing nodes in a data center, installing an OVS virtual switch for externally providing network services on computing nodes and network nodes, and installing only on computing nodes for monitoring The Fast‑DVR controller of the OVS virtual switch traffic, and update the channel bridge through the Fast‑DVR controller, the Fast‑DVR controller deployed on each computing node is centrally controlled by the control node; the user sends the Fast‑DVR controller through the API Deliver custom configurations. When the different network traffic between computing nodes exceeds the network traffic threshold, the Fast-DVR controller dynamically plans the network topology between computing nodes. In the present invention, the monitoring of the network traffic on the computing nodes is realized, and the network routing function is realized through the network nodes and the computing nodes, which not only simplifies the topology of the entire data center, but also can significantly reduce the network throughput pressure of the network nodes, and improve The overall network performance of the data center is improved.

Description

technical field [0001] The invention relates to the technical field of network virtualization in cloud computing, in particular to a method for realizing high-speed distributed routing between computing nodes in a data center. Background technique [0002] The cloud computing system in the data center is composed of multiple nodes such as control nodes, computing nodes, and network nodes. Computing nodes are responsible for running virtual machines that provide services to respond to user requests, network nodes provide external and internal network services for the cloud computing system, and control nodes are responsible for the normal operation of the cloud computing system. As more and more businesses and data are migrated to cloud computing systems, if efficient data routing cannot be achieved in the data center, it will bring immeasurable losses to users. [0003] At present, the routing technology of the data center mainly includes: centralized routing technology and...

Problems solved by technology

Although distributed routing technology can reduce the pressure on network nodes, because the network name space (Network Name Space) technology is still used to simulate routers and route data, the topology structure on computing nodes is too complex, which cannot effectively reduce the entire network delay. (Latency), and will affect the computing performance of computing nodes
