Abstract – Many commercial and open-source network simulators are available; however, most of them are not suited for novices in college and school education or learning. Moreover, although Ethernet has recently become much more important, simulators that can be used for this purpose is rare because most simulators suited for education and learning are designed for IP communication. The author developed a simple CLI-based Ethernet simulator that can display contents of Ethernet packets to send or to receive in terminals and contents of MAC address tables in switches in “real time”, and used the simulator in a university class for learning computer networks. The simulator, which is in public domain, is written in Python and, thus, runs on Windows, Macintosh, Linux, and other operating systems. The use of this simulator was evaluated based on a report assignment. The evaluation result shows that the average score of the reports written by using the simulator was much better, although it is not statistically significant because the number of students is small. The simulator seems to be effective to learn behaviors of Ethernet-based networks.

Abstract – Our previous work enabled “federation-less federation”, which means a federation of multiple network-virtualization platforms that do not support federation functions, and applied this method to a homogeneous federation of platforms called the “VNode” infrastructures. In this study, this method was applied to a heterogeneous federation of the ProtoGENI and the “VNode”. We intended to federate these platforms through a single management interface. However, the federation architec- ture of GENI, which is called the slice-based federation architecture (SFA), cannot be used for single-interface federation but we could not modify the ProtoGENI platform to enable it. Therefore, a method for applying federation-less-federation to ProtoGENI was developed. It enabled federation of these platforms by adding several nodes but without modifying preexisting platforms. This method was applied to federation of the ProtoGENI platform at the University of Utah and two VNode infrastructures in Japan, the slice creation and deletion time was measured and evaluated to be acceptable. Although this federation-less-federation imple- mentation still has several minor problems, it was proved to be useful for experiments and demonstrations.
