A disaggregated router is a networking device that separates the hardware and the software, allowing for greater flexibility, scalability, and innovation. Unlike traditional routers that have both the control and forwarding functions integrated into a single device, a disaggregated router separates these functions into distinct modules that can be managed and updated independently. This allows for the forwarding plane to be optimized for high-speed data processing while the control plane can focus on routing decision-making and management. The result is a more flexible and efficient networking solution that can adapt to changing network demands and support new technologies.
