ISO/IEC TR 29181-3:2013 contains the problem statement and requirements for switching and routing in the Future Network, in particular:

1. description of the requirements for carrying data over digital networks;
2. description of the ways in which these requirements are not satisfied by current networks;
3. functional architecture for switching and routing in the Future Network; and
