CNI Plugins vs VMware NSX Container Plugin

CNI Plugins is a collection of reference and example network plugins for configuring connectivity in Linux and Windows containers. CNI supplies a specification and libraries, plus a command-line tool for executing plugins and a Go library for application integration. Interface options include bridge, ipvlan, loopback, macvlan, point-to-point, VLAN, host-device, and dummy; Windows-specific plugins include win-bridge and win-overlay. IP address management choices cover DHCP, host-local allocation tracking, and static IPv4 or IPv6 allocation. Meta plugins handle interface tuning, port mapping, bandwidth limits, source-based routing, and firewall rules, and a sample plugin illustrates custom plugin development. CNI focuses on connecting containers and removing allocated resources when a container is deleted. The project is distributed under Apache License 2.0 and is a Cloud Native Computing Foundation project. It is free, with a plan listed at free.
