Understanding Eucalyptus EDGE Mode

Eucalyptus EDGE mode offers the most features of the EC2 Classic-compatible networking modes. It is designed to integrate into already extant (or straightforward to deploy) underlying network topologies. However, EDGE mode can impose constraints in certain environments.

In EDGE networking mode, the components responsible for implementing Eucalyptus VM networking artifacts are running at the edge of a Eucalyptus deployment: the Linux host machines acting as Node Controllers (NCs). On each NC host machine, a Eucalyptus stand-alone service, eucanetd, runs side-by-side with the NC service. The eucanetd service receives dynamically changing Eucalyptus networking views and is responsible for configuring the Linux networking subsystem to reflect the latest view.

EDGE networking mode integrates with your existing network infrastructure, allowing you to inform Eucalyptus, through configuration parameters for EDGE mode, about the existing network, which Eucalyptus then will consume when implementing the networking view.

EDGE networking mode integrates with two basic types of pre-existing network setups:

Important: EDGE networking mode integrates with networks that already exist. If the network, netmask, and router don't already exist, you must create them outside Eucalyptus before configuring EDGE mode.
