Abstract:To meet future requirements of society and economy,current IP based Internet is required to be more scalable,more secure,more manageable and lower energy consumption and etc.But traditional solutions based on incremental evolution are proved to be ineffective.Five years ago,western developed countries had launched "Post IP" research to reinvent future Internet by using "clean-slate" (from the scratch) approach.However,there is no corresponding national-scaled project on "Post IP" in China today.Therefore,it is time for China to significantly step up investment in the "Post IP" research as early as possible so as to develop internet’s next generation,and take the opportunity of innovation of internet.It will be helpful for china to lead the future Information and Communications Technologies (ICT) competition over the world,and promote industry of future internet.
