The Nydus Canal serves as a quick transport link from one location to another. The Canal needs two anchoring points, entrance and exit nodes, but once both have been set down, the Zerg forces can travel both ways. Only one Zerg ground unit can be transported at a time, but the process is quick and a large force can travel through in a matter of seconds. The Nydus Canal also has the interesting ability of being able to place its exit node on the Creep of any Zerg colony, friendly or not.
