OCARINA: Optimizations to Compel Adoption of RINA
RINA, the Recursive InterNetwork Architecture by John Day , is a novel “back to basics” type approach to networking that is fundamentally different from today's networks. It shows great potential in many aspects of networking, e.g. by simplifying management and providing better security. The recursive nature of RINA calls for radically different approaches to how networking is performed, including congestion control and routing. In OCARINA, we develop new congestion control and routing/forwarding mechanisms for RINA. Today, in the Internet, congestion control is performed end to end, but by locating the control closer to the entity that is being controlled, RINA should allow us to achieve much better performance. Also, in the Internet, routing is very static; in OCARINA we research new dynamic ways to perform routing and forwarding. Our new mechanisms are implemented, tested and evaluated in RINA, and we address how RINA can be gradually deployed in (over / under / alongside) the Internet.

About the project
In OCARINA, we team up with leading international researchers to address these challenges. We show that RINA, with our new mechanisms, is indeed a much better solution for the Internet than TCP/IP in terms of performance. We also move RINA closer to real world deployment and motivate its adoption.
- Research & develop new congestion control mechanisms in RINA,
- Research & develop new dynamic routing and resiliency mechanisms in RINA,
- Deploy RINA as an overlay/underlay/alongside the Internet.
- Scientific articles,
- Source code of developed mechanisms.
The Internet's end-to-end'ness of congestion control and its very static routing are inevitable by-products of its underlying architectural design (e.g., in the Internet, it is virtually impossible to let load-based routing scale without obtaining oscillations). With the Recursive InterNetwork Architecture “RINA”, the natural way of applying such algorithms is very different, with control executed much closer to where the problem is. It is, therefore, an ideal vehicle for investigating drastic changes to how congestion control and routing could be done, and it provides the framework that we work in.
