Our model therefore not only provides each node with an independent replica of the entire standard network stack, thus enabling highly realistic and detailed emulation of network routers; it also enables each virtual node to run a private copy of any unmodified user-level application, including routing protocol daemons, traffic generators, analyzers, or application servers. Furthermore, in later development phases we expect to enable each virtual node to support multiple network protocols concurrently, such as both IPv4 and IPv6, which would bring us a step closer to allowing for emulation of true multiprotocol networked environments... As invaluable tools in networked and distributed systems research, network emulators and simulators offer a viable alternative to live experimental networks. We are developing a realistic network topology emulation / simulation framework based on the FreeBSD and Linux operating system kernel partitioned into multiple lightweight virtual nodes, which..
