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.
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.
Matthew Finnie, CTO of Interoute, told to Computing that the Internet is no longer fit for purpose, and that IP is no longer an ideal way to consume the content and services provided through it. A potential solution that holds promise is to rebuild the Internet using RINA. The whole article is avilable via the Computing website.
