We detail the implementation of RUBEN, a scalable emulator based on software routers which implements and evaluate energy-aware algorithms in backbone networks. Our solution adopts virtualization techniques to reproduce the behavior of an entire backbone network on a single machine. Each virtual machine is a router implementing an energy-aware algorithm. Moreover, RUBEN is tailored to the measurements...
Traffic matrix estimation in communication networks is challenging problem, whose solution provides a valuable management and planning tool. Given the range of technologies able to reconfigure the resource assignment, real-time knowledge of the traffic matrix enables smart adaptive traffic management functions. A new perspective is given to the traffic matrix estimation problem by the Software Defined...
