Using Docker Containers as Mininet Hosts

Introduction
Talentica believes in continuous learning and innovation. We the Talenticans have always been encouraged to undertake learning and experimenting with emerging technologies. With the same objective, we have setup an internal R&D group working on upcoming areas. Software defined networking (SDN) is one the areas where we are developing proficiency.
