30 * The Network class is the base class for classes that implement the
31 * interconnection network between components (processor/cache
32 * components and memory/directory components). The interconnection
33 * network as described here is not a physical network, but a
34 * programming concept used to implement all communication between
35 * components. Thus parts of this 'network' will model the on-chip
36 * connections between cache controllers and directory controllers as
37 * well as the links between chip and network switches.
