Passive optical network (PON) packet processor

摘要

A passive optical network (PON) packet processor for processing PON traffic includes a core processor for executing threads related to the processing of PON traffic and a plurality of hardware (HW) accelerators coupled to the core processor for accelerating the processing of said PON traffic. A memory unit is coupled to the core processor for maintaining program and traffic data. In an embodiment of the present invention, the PON packet processor includes a scheduler that optimizes the execution of PON related tasks.

主权项

1. A passive optical network (PON) packet processor for processing PON traffic, said PON packet processor comprising:
a core processor configured to execute a plurality of threads related to said processing of said PON traffic, said PON traffic comprising upstream data including Ethernet frames and downstream data chunks; a plurality of hardware (HW) accelerators, coupled to said core processor, configured to accelerate and to optimize execution of said plurality of threads, said plurality of HW accelerators being configured to accelerate execution of said plurality of threads as compared to executing said plurality of threads using only said core processor,
wherein a first HW accelerator of said plurality of HW accelerators comprises:a scheduler having a first mechanism configured to perform priority-based selection of said plurality of threads and a second mechanism configured to enable requests for execution of said plurality of threads; and a memory unit, coupled to said core processor, that stores program and traffic data.
