Advanced Networks have been studied through emulation testing connectivity and management under IPv4 and IPv6 using their corresponding routing and management protocols such as ISP companies do for backbone infrastructure. In this work, given four different and complex backbone advanced networks in different regions in the world, four different kinds of files have been transmitted from one extreme to another for each backbone network then time and computational resources have been considering, testing GNS3 capabilities when emulating under IPv6 using limited CPU and RAM resources. The four advanced networks are Africa Connect for Africa, GEANT for Europe, AMERONET for America, it means the joint of CANARIE, INTERNET2 and CLARA, and Pacific Wave for many countries in the pacific. Those four advanced networks involve 187 backbone routers. Given a specific hardware resource, results show capabilities and limitations when testing different file transfers when emulating advanced networks.
