摘要： An example embodiment of the invention provides a process for lockless processing of hierarchical bandwidth partitions configurations in multiple processor architectures. In one embodiment, the process runs in an NPU's data plane and receives a packet for a partition from a child partition through a work queue. The process determines a suggested target bandwidth rate for the receiving partition's child partitions, based in part on a count of active child partitions, if a predefined time interval has passed. The process adopts a target bandwidth rate for the receiving partition suggested by the receiving partition's parent partition, if the receiving partition is not a root partition and the predefined time interval has passed. The process then transmits the packet to the receiving partition's parent partition through the work queue, if the receiving partition is not a root partition. Otherwise, the process transmits the packet to a port.

摘要： Methods, apparatuses, and systems directed to efficient compression processing in system architectures including a control plane and a data plane. Particular implementations feature integration of compression operations and mode selection with a beltway mechanism that takes advantage of atomic locking mechanisms supported by certain classes of hardware processors to handle the tasks that require atomic access to data structures while also reducing the overhead associated with these atomic locking mechanisms.
