Aware of the benefits that Software-Defined Networking (SDN) can entail for traffic engineered services, the pan-European National Research and Education Network (NREN) Géant has started to work on an SDN-based solution to provide Bandwidth on Demand (BoD) services. The proposed solution relies on a framework called DynPaC, which is able to provide resilient L2 services taking into account bandwidth...
Novel approaches for network virtualization at Layer 2 which are not based on VLAN have became a real possibility since the appearance of Software Defined Networking and OpenFlow in particular. We have deployed our own network virtualization facility based on Layer 2 prefixes using OpenFlow: the EHU OpenFlow Enabled Facility (EHU-OEF). We have implemented a solution that allows research and production...
The Cloud computing paradigm entails a challenging networking scenario. Due to the economy of scale, the Cloud is mainly supported by Data Center infrastructures. Therefore, virtualized environment manageability, seamless migration of virtual machines, inter-domain communication issues and scalability problems are some of the main concerns that should be addressed. A recently proposed abstract model...
