Travelling from Heaven to Hell

Japan, Singapore, Malaysia, Thailand, United States, United Kingdom, Belgium, Netherlands, South Africa, Slovenia etc… are the countries I have visited earlier but the most unique country I visited this time is Norway. The country of heaven, the country of kindness, the country of apex in development, the happiest country in the world bla.. bla..bla…all I heard about is a true facts once I experienced myself when first I arrived in Norway on July 13. It was so kind that professor was eager waiting in the airport to welcome me. Almost 30Km drives, we reached in a place near a jungle. Helmut stopped the car, got out from car and told, ‘welcome babu, this is your place’. At the beginning, I am sucked, watched all four directions if there are any houses nearby. The house is located near the jungle and no more houses attached on it. I felt like how could I stay here alone? The ground floor is under-ground. It looks like a simple one flat house what we called Katero (कटेरो) in Nepalese language. When entered into the house, socked again by seeing its amazing decoration and furnishing/management. My feeling is directly connected and felt like no more fear of living alone. Prof. Martina introduced all the features inside the house and left me to pick me back to campus on Tuesday morning. Sidhartha (Rita Kumar’s Son) picked me up next day to market. He helped me out for bus card, phone recharge and buy some food stuffs.

Everything managed on Tuesday (17th July) at office including office access, library access etc…at Department of ProductDesign, NTNU. Also Met & greet HoD Dr. Ole Andreas Alsos and other friends at office. But university is on vacation, and hence not much student’s flow at the department.

Being not familiar with travel and locations, I was having little fear about how to reach campus by

Software Defined IPv6 (SoDIP6) Experimentation with Mininet

In this blog post, I just want to introduce a new experiment with new term called SoDIP6. The world-wide network currently in operation is a Legacy IPv4 Network. We understand that legacy IPv4 network has several drawbacks as compared with next generation programmable IPv6 network. Legacy network is vertically integrated and complex in configuration with waste of addresses due to class-ful addressing mechanism. IPv6 is the one more secure, flexible, scalable and robust addressing protocol. Similarly, comparing with legacy network management, Software Defined Network is the horizontally distributed programmable and so flexible as well as controllable networking management approach currently in the central point of research for worldwide researchers. I just combined the two terminologies as SDN and IPv6 with a single name as Software Defined IPv6 or in short ‘SoDIP6’. SDN and the IPv6 are interrelated technologies where IPv6 operate on the network layer and SDN deals with the management of the networking operations as management layer. “The future networking infrastructure fully IPv6 operable and controlled/managed by the SDN controller is recognized as a SoDIP6 network”. The possibility of next generation energy efficient and smart networking could only be dreamed with the availability of programmable IPv6 network.

Mininet is the one best emulation tool used for testing of network operation and management. In this blog, I tried to experiment the dual stack SoDIP6 network with functioning of IPv4, IPv6 and the SDN.

I got very few (almost none) experiment incorporating IPv6 only network in the Mininet.
