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.
1. The pseudo-header
John Day, in this interview by Richard Bennett of High Tech Forum, lays out the elements of RINA at a high level, discussees the nature of the RINA transition, and assesses the state of three large-scale RINA trials in Europe.
Diego Lopez, in this post at the Telefonica "Think Big" blog (in spanish), explains that the current Internet has reached a size that has exceeded the expectations of its original designers by orders of magnitued. In order to reach this size many patches have been "organically" incorporated into the architecture, making it more complex, hard to manage and very prone to failures. RINA could be the solution to provide scalability to the next generation Internet.
Martin Geddes, a renowned expert on the telecommunications and distributed computing performance business, characterized RINA as "nuclear networking" compared to conventional TCP/IP networks. Mr. Geddes, who participated in the first international RINA workshop, shared his takeaways of the event in this blog post.
