Problems solved by technology

[0004] The purpose of the embodiments of the present application is to provide a vhost-user-based service chain implementation method and device. Each node of the service chain uses shared memory, which greatly reduces the amount of memory data copying, improves system efficiency, and solves the problems in the existing methods. The network traffic data between the service chain nodes in the virtualization scenario needs to be copied multiple times, which leads to the problem of occupying too many system resources

Abstract

The embodiment of the invention provides a vhost-user-based service chain implementation method and device, and relates to the technical field. The method comprises the following steps: storing network traffic data into a vring circular queue of a shared memory; the virtual machines of all the nodes of the service chain sequentially obtain the network flow data from the vring circular queue according to the arrangement sequence and process the network flow data; and the processed network flow data is re-stored in the vring round-robin queue, and each node of the service chain uses a shared memory, so that the copy amount of the memory data is greatly reduced, the system efficiency is improved, and the problem that the network flow data needs to be copied for multiple times among service chain nodes of a virtualization scene in the existing method is solved. And too many system resources are occupied.

Description

technical field [0001] The present application relates to the technical field of cloud computing, in particular, to a vhost-user-based service chain implementation method and device. Background technique [0002] During network transmission, data packets need to pass through various types of nodes. For some network nodes with special functions, network traffic will pass through these nodes sequentially according to the functional requirements of the nodes. Such as a firewall, inflow from the specified port, and leave from the specified port. The one-way traffic links formed by these nodes are called service chains. In the physical network environment, each node is a hardware device, and the service chain is formed in the process of physical networking. [0003] In the existing method, the number of times traffic data needs to be copied between each node in the service chain is consistent with the number of nodes, and the longer the link, the more copies will be made, resul...
