Consider the switched network snooping protocol described above and the cache contents from Figure 4.37. What are the sequence of transient states that the affected cache blocks move through in each of the following cases for each of the affected caches? Assume that the address network latency is much less than the data network latency.
a. P0: read 120
b. P0: write 120 <-- 80
c. P15: write 120 <-- 80
d. P1: read 110
e. P0: write 108 <-- 48
f. P0: write 130 <-- 78
g. P15: write 130 <-- 78
