Abstract:
The present disclosure is directed to a network processor for processing high volumes of traffic provided by todays access networks at (or near) wireline speeds. The network process can be implemented within a residential gateway to perform, among other functions, routing to deliver high speed data services (e.g., data services with rates up to 10 Gbit/s) from a wide area network (WAN) to end user devices in a local area network (LAN).
Abstract:
Methods, systems, and computer program products for managing memory of a passive optical network (PON) are provided herein. The method includes the steps of receiving a plurality of data packets from a stream of packets. A plurality of packet descriptors associated with each data packet is stored in a configurable first queue. The first queue includes a plurality of cache slots and is managed in an internal memory. A state of the first queue is identified. In response to the state of the first queue meeting a predetermined threshold, packet descriptors from a tail cache slot of the first queue are transferred to a second queue. The second queue is managed in an external memory.
