Abstract: The present disclosure relates to a method for facilitating dynamic power allocation and distribution in a multi-port power sourcing device. The method comprises receiving, by a first set of instructions to be executed on a multi-port power sourcing device, the one or more input parameters at the multi-port power sourcing device. The first set of instructions is executed at the multi-port power sourcing device. The first set of instructions pertains to power distribution and operational decision-making across each of the port of the multi-port power sourcing device. Further, a second set of instructions are executed based on the executed first set of instructions. The second set of instructions is executed to manage operations pertaining to a single port of the plurality of ports of the multi-port power sourcing device. The executed first set of instructions control the second set of instructions via a request-response communication interface.
