Containerized applications had been the biggest driver for a number of SDN projects which came to life in the last year. There are several challenges that highly-dynamic and fully-distributed container orchestration systems impose on SDN architectures.

This presentation is geared towards anyone working with open source SDN technologies, as well as those who would like to ensure the robustness of their containers' connections / of their container connectivity.

Several approaches/options for container networking will be presented, including Weave Net, an open source overlay network for Docker containers. We will demonstrate the in-kernel Open vSwitch datapath used in Weave Net; this manages VXLAN tunnel configuration across hosts, without requiring the user to be a networking expert. We will also highlight how Weave Net provides service discovery and load balancing through a robust, distributed DNS. Users don't need to understand the underlying complexity, nor do they need to make changes to their application.

In this talk, Weave Net's engineers will share what is required to deliver this level of user experience, through the implementation decisions they have made.
