  1. Chassis Manager Controller (CMC) Service
  2. Frisbee Service?
  3. Inventory Service
  4. Login Service?
  5. OML Service?
  6. PXE Service?

Node Handler

The nodehandler is the central experiment controller. A central NodeHandler process communicates with NodeAgents, one on each active node in the testbed. The NodeHandler is hosted on one of the testbed's utility servers (typically called console). Applications are loaded and executed by a NodeAgent on instructions from the NodeHandler. These instructions will also include the initial property settings for the applications.

In addition to providing interfaces for experiment execution, nodehandler also provides the following built in commands:

Node Agent

Component that runs on a node and is in the receiving side of the NodeHandler commands.
