Outline of Final Research Achievements

As for future networks like optical circuit/packet/burst switching networks, new unified network infrustructure called Content Swithing Network(CSN), which deal with optical/electrical switching behavior in terms of content transfer, has been proposed. CSN was specifically designed and described its behavior in the specification. In particular, this flexible paradigm shift solves an issue that translucent networks are facing concerning physical impairments (e.g. signal degradation) over long-haul transmissions: signal regeneration is expensive and it is difficult to decide where transponders should be installed. CSN allows regeneration on the fly everywhere, thanks to our proposed algorithms. Through the computer simulation made by Omnet++, it was demonstrated that the proposed CSN outperforms the conventional Optical Circuit Switching Networks.
