IRATI is a open source implementation of RINA for OS/Linux systems that allows researchers and innovators to experiment with RINA networks. RINA is a new Internetwork architecture that supports without the need of extra mechanisms mobility, multi-homing and Quality of Service, provides a secure and configurable environment and allows for a seamless adoption. IRATI implements the core RINA protocols and multiple policies to customize such protocols to different environments. Policies can be developed via a Software Development Kit (SDK). IRATI provides an API for applications to natively use RINA IPC services, as well as multiple monitoring utilities and example applications.
