Recursive InterNetwork Architecture (RINA)
The Recursive InterNetwork Architecture (RINA) is a computer network architecture that unifies distributed computing and telecommunications. RINA's fundamental principle is that computer networking is just Inter-Process Communication or IPC. RINA reconstructs the overall structure of the Internet, forming a model that comprises a single repeating layer, the DIF (Distributed IPC Facility), which is the minimal set of components required to allow distributed IPC between application processes. RINA inherently supports mobility, multi-homing and Quality of Service without the need for extra mechanisms, provides a secure and programmable environment, motivates for a more competitive marketplace, and allows for a seamless adoption.
