RINA, the Recursive InterNetwork Architecture by John Day [1], 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 will 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 will research new dynamic ways to perform routing and forwarding. Our new mechanisms will be implemented, tested and evaluated in RINA, and we will see how RINA can be gradually deployed in (over / under / alongside) the Internet.

The dream of being able to build safe, self-driving, autonomous cars are about to become a reality. Companies like Mercedes-Benz, Audi, Volvo and Google have all shown sophisticated prototypes of cars being able to sense the environment and navigate through dynamic surroundings without human intervention. The use of autonomous cars, however, not only makes it possible for people to spend their time more efficiently as no drivers are needed, but in addition traffic administration itself could be optimized and the utilization of the available roads improved. In particular, the utilization of the roads in a city during rush hours could be greatly improved if a holistic approach to congestion control is taken to avoid traffic jams.

InfiniBand is a state-of-the-art high performance networking technology used in many of the worlds largest supercomputers, clouds and modern datacenters where high bandwidth and low latency is required. InfiniBand supports congestion control with a parameterised mechanism, but proper guidelines or policies for using congestion control in InfiniBand do not exists.

AQM -- Active Queue Management (AQM) is a strategy to drop or mark packets in router buffers to signal the onset of congestion to the senders and therefore to avoid the buffer to become full. The persistently full buffers in network routers along the Internet paths lead to excessive latency that negatively affect the performance of multimedia flows (e.g. video streaming, VoIP and online gaming).  Therefore it's vital to deploy AQM at network routers to assure the low latency, more specifically on the access links such as home routers, access points and modems.
