Fuente: WIPO "sustainability" Existing session routing strategies tend to primarily focus on performance and cost efficiency, with less emphasis on energy consumption or sustainability. To address this, devices, systems, methods, and processes that facilitate sustainability-aware collaboration session activity routing are described herein. A session control logic receives attributes of a plurality of network devices and determines sustainability scores for the plurality of network devices. The session control logic further selects a target network device from the plurality of network devices based on the sustainability scores, and directs a collaboration session activity to the selected target network device. Thus, the target network device receives the collaboration session activity in response to its sustainability score being optimal in comparison to respective sustainability scores of peer network devices. As a result, the session control logic explicitly considers sustainability impact of a routing decision when determining routes, leading to improved energy efficiency or reduced environmental impact.
