In recent years, there have been multiple enhancements in virtualization technologies, cloud computing, and network programmability. The emergence of concepts like Software Defined Networking (SDN) and Network Function Virtualization (NFV) are changing the way the Internet Service Providers manage their services. In parallel, the last decade...

Many companies and organizations are moving their applications from on-premises data centers to the cloud. The cloud infrastructures can potentially provide an infinite amount of computation (e.g., Elastic Compute) and storage (e.g., Simple Service Storage). In addition, all cloud providers propose different offers: IaaS, PaaS, and SaaS. This...

Networks have become complex systems that combine various concepts, techniques, and technologies. As a consequence , modelling or simulating them is now extremely complicated and researchers massively resort to prototyping techniques. Among other tools, Mininet is the most popular when it comes to evaluate SDN propositions. It allows to emulate...

Networks became so complex and technical that it is now hard if not impossible to model or simulate them. Consequently, more and more researchers rely on prototypes emulated in controlled environments and Mininet is by far the most popular tool. Mininet implements a simple, yet powerful API to define and run network experiments on a single...

With the increased complexity of today's networks, emulation has become an essential tool to test and validate a new proposed networking solution. As these solutions also become more and more complex with the introduction of softwarization, network function virtualization, andartificial intelligence, there is a need of scalable tools to carry...

To handle the ever growing demand of resource intensive experiments distributed, network emulation tools such as Mininet and Maxinet have been proposed. They automatically allocate experimental resources. In this work, we show that resources are poorly allocated, leading to resource overloading and hence to dubious experimental results. This is...

With the ever growing complexity of networks, researchers have to rely on test-beds to be able to fully assess the quality of their propositions. In the meanwhile, Mininet offers a simple yet powerful API, the goldilocks of network emulators. We advocate that the Mininet API is the right level of abstraction for network experiments....

With the emergence of Network Function Virtual-ization (NFV) and Software Defined Networking (SDN) efficient network algorithms considered too hard to be put in practice in the past now have a second chance to be considered again. In this context, we rethink the network dimensioning problem with protection against Shared Risk Link Group (SLRG)...

ISP networks are taking a leap forward thanks to emerging technologies such as Software Defined Networking(SDN) and Network Function Virtualization (NFV). Efficient algorithms considered too hard to be put in practice on legacy networks now have a second chance to be considered again. In this context, we rethink the ISP network dimensioning...

More than ever, data networks have demonstrated their central role in the world economy, but also in the well-being of humanity that needs fast and reliable networks. In parallel, with the emergence of Network Function Virtualization (NFV) and Software Defined Networking (SDN), efficient network algorithms considered too hard to be put in...
