Abstract

Abstract:

The development of cloud computing has made container technology a hot research issue in recent years. The container technology provides a basic support for micro service architecture, while container networking plays an important role in application of the container technology. In this paper, we study the technical implementation of the Flannel module, a network plug-in for Docker containers, including its functions, implementation principle, utilization, and performance. The performance of Flannel in different modes is further tested and analyzed in real application scenarios.

Key words: container technology, Docker, network plug-in, Flannel

Mode	Rate (M/s)	Description
Direct transmission between two hosts	94.3	There is a normal performance loss in direct transmission between two hosts.
UDP	92.7	There is greater performance loss.
VXLAN	91.2	There is greater performance loss.
Host-GW	94.3	The performance is approximate to that of direct transmission between two hosts.
