Method and device for processing access request packet on node of micro-service cluster

Abstract

The embodiment of the invention relates to the technical field of communication, and particularly to a method and a device for processing an access request packet on a node of a micro-service cluster. The method and the device for processing the access request packet on the node o the micro-service cluster are used for improving the access performance of services in the micro-service cluster under the condition of not adding hardware cost. According to the embodiment, the method comprises the steps of receiving an access request packet sent by an intranet client, wherein the subnet masks of the intranet client and a node are same; determining a target service port identifier based on a virtual service port identifier carried by the access request packet, and updating the virtual service port identifier carried by the access request packet by using the target service port identifier; and sending the updated access request packet to a target service port which is identified by the target service port identifier. Therefore, a cluster entrance agency is not required to forward the access request packet of the intranet client, and the access performance of the services in the micro-service cluster can be improved under the condition of not increasing the hardware cost.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of cloud computing, and in particular to a method and device for processing an access request packet on a node of a microservice cluster. Background technique [0002] In the process of migrating traditional service applications to cloud computing microservice clusters, since many service applications have been deployed in the production environment, it is difficult to migrate the entire production environment to cloud computing microservice clusters at one time, and some service applications cannot be migrated to the cluster due to their own reasons , which exists outside the cluster. In consideration of the security of the microservice cluster, the internal and external networks of the microservice cluster must be isolated from each other. Therefore, clients outside the microservice cluster cannot directly access the services in the cluster. Clients outside the microservice clust...

Problems solved by technology

[0003] In the prior art, when a client outside the microservice cluster accesses services in the cluster, both the intranet client and the external network client use open source proxy software such as Nginx and HAProxy as the cluster entry proxy, that is, the cluster entry proxy needs to forward For all requests sent by intranet clients and external network clients, this mode of centralized forwarding through the cluster entrance agent can easily become a system bottleneck. Access to services within a service cluster

In order to solve the system bottleneck, in the existing technology, redundant deployment is required for the cluster entrance agent itself, and a layer of load balancing equipment is added in front, which will increase network complexity and hardware costs
