33 * Description: The SimpleNetwork class implements the interconnection
34 * SimpleNetwork between components (processor/cache components and
35 * memory/directory components). The interconnection network as
36 * described here is not a physical network, but a programming concept
37 * used to implement all communication between components. Thus parts
38 * of this 'network' may model the on-chip connections between cache
39 * controllers and directory controllers as well as the links between

51 * The network encapsulates all notion of virtual global time and is
52 * responsible for ordering the network transactions received. This
53 * hides all of these ordering details from the processor/cache and
54 * directory/memory modules.
