Hi Monobrata, To see the number of VNs required by each protocol, you should take a look at its .sm files. Take a look at src/mem/protocol/MOESI_CMP_directory-L1cache.sm, src/mem/protocol/MOESI_CMP_directory-L2cache.sm, src/mem/protocol/MOESI_CMP_directory-dir.sm and src/mem/protocol/MOESI_CMP_directory-dma.sm Search for "virtual_network"
