Abstract: A packet buffer stores packet data of packets received by a master device. The packet buffer includes a non-guaranteed buffer, a guaranteed buffer, and a reserved buffer. The non-guaranteed buffer is visible to the master device, and is not guaranteed to provide one free cell space for one cell in a first-type packet before the non-guaranteed buffer is full. The guaranteed buffer is visible to the master device, and is guaranteed to provide one free cell space for one cell in a second-type packet before the guaranteed buffer is full. The reserved buffer is invisible to the master device, and is arranged to provide headroom for the guaranteed buffer.

Abstract: A random early drop (RED) based processing circuit includes a scheduler, an RED-based decision logic and a controller. The scheduler generates a trigger event according to an RED-based operation schedule. The scheduler is coupled to a software interface, and the RED-based operation schedule in the scheduler is programmed via the software interface. The RED-based decision logic performs at least a first RED-based operation to generate a first RED decision accordingly. The controller receives at least the trigger event, and triggers the RED-based decision logic to perform the first RED-based operation according to at least the trigger event.

Abstract translation: 基于随机早期丢弃（RED）的处理电路包括调度器，基于RED的决定逻辑和控制器。 调度器根据基于RED的操作调度生成触发事件。 调度器被耦合到软件接口，并且通过软件接口对调度器中的基于RED的操作调度进行编程。 基于RED的决定逻辑执行至少第一基于RED的操作以相应地产生第一RED决定。 控制器至少接收到触发事件，并且触发基于RED的决定逻辑以至少根据触发事件执行基于RED的第一操作。
