Abstract

The SDN-based microservice load balancing method belongs to the technical field of software-defined networks. The invention introduces the SDN network into the micro-service framework, utilizes the global network view of the SDN and the refined control capability of the network flow, and provides a more refined load balancing capability for the micro-service invocation. Through virtual ip rewriting technology and calling link analysis technology, load balancing calculation is performed based on the overall load condition of the calling link, and the load balancing strategy is converted into the flow table form of network forwarding, so as to achieve high-efficiency load balancing that is imperceptible to the caller. .

Description

technical field [0001] This patent relates to an SDN-based microservice load balancing method, which belongs to the technical field of software-defined networks. Background technique [0002] Microservice is a new concept of Internet distributed service design. By dividing services into fine-grained and functionally independent microservice modules, it can achieve functional decoupling and independent evolution of services. However, in microservice deployment, load balancing is generally implemented by the calling end. The calling end obtains the IP addresses of all servers that provide services through the service discovery mechanism, and implements load balancing through random requests, round robin, and other methods. However, this kind of load balancing does not consider the forwarding efficiency of the overall network, nor does it comprehensively consider the load balancing of each invocation node in a service invocation link. SUMMARY OF THE INVENTION [0003] This p...
