FIELD: physics, computer engineering.
SUBSTANCE: invention relates to information processing devices. The technical result is achieved by comparing an occupancy level of the buffer of a port of a router to a threshold, and controlling the port to operate at a first voltage and frequency based at least in part on the comparison, and at least one other port of the router is controlled to operate at a second voltage and frequency.
EFFECT: optimising performance power in each port of a router.
