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.

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 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.
