One goal of RINA is to distill a theory based on fundamental principles, on what the problem tells us. Largely, this has come down to finding the invariances. The RINA Reference Model describes that theory, as we now understand it. We have found that by not breaking the invariances we don’t encounter “devils in the details,” but quite the opposite, the theory tends to yield simpler results for thorny problems. But we are always testing it. Trying to uncover things we haven’t seen.
OCARINA (Optimizations to Comple Adoption of RINA), is the name of a new research project from the University of Oslo (UiO) that has just been funded by the Norwegian government, under its Toppforsk program.
In a recent presentation at a standards event, someone cited a quote from Vint Cerf that they made a mistake binding IP to TCP with the pseudo-header. Supposedly not doing this would make it easier to solve some of the current problems facing the Internet, such as mobility. Unfortunately, this isn’t the case. In fact, the evidence points in the opposite direction.
