A passive optical network (PON) processor comprises a packet processor for processing packets belonging to a certain flow through a plurality of processing stages of a programmable data-path; a microprocessor-data for performing one or more user-defined functions in the programmable data-path on designated packets belonging to the certain flow, wherein packets of respective flows to be processed by the microprocessor-data are designated in a flow table; a microprocessor-control for managing connections handled by the PON processor; a data-path bus for connecting the packet processor and the microprocessor-data, wherein the designated packets are transferred between the packet processor and the microprocessor-data on the data-path bus; and a control-path bus for connecting the packet processor and the microprocessor-control.

Method and system for managing a buffers pool. The system may include a first processor coupled to a general memory having allocation ring and de-allocation ring portions; and a second processor to perform internal accounting of pointer(s) buffer(s). The second processor has an internal storage array logically divided into first and second storage spaces. The second processor releases temporarily un-required buffer(s) pointer(s) to the first storage space, or to the second storage space if the first storage space is full. The second processor utilizes allocated buffer(s) pointer(s) accumulated in the first storage space. The second processor is to cause a DMA engine to move a bulk of two or more buffer(s) pointer(s) from the allocation ring to the first storage space, and to move a bulk of two or more buffer(s) pointer(s) from the second storage space to the de-allocation ring.
