Documentation

Overview

This is a bare-bones CNI plugin (with only ADD actually implemented, other methods are no-ops) used to setup a network bridge w/ tap in order to compare performance of a bridge-based VM network w/ a TC-based approach, such as that created by the tc-redirect-tap plugin. It expects to be chained after the ptp plugin and sets up a layout like the following: [host] <- vethA <- vethB <- [bridge] <- tap0 <- [vm guest]

with "vethA <- vethB" crossing a network namespace boundary.
