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. 38 */ |
