摘要: Various techniques can be used to handle frames within multi-stage switching fabric. For example, in one method, a frame and an associated frame header are received at a switching fabric stage. The associated frame header includes a first field and a second field. The method selects one or more fabric points of exit within the switching fabric stage, based on the second field. The first field is used to select one or more other fabric points of exit within another switching fabric stage, and thus two different fields within the associated frame header specify fabric points of exit. The method then sends the frame to the selected fabric points of exit within the switching fabric stage.

摘要: A self-adjusting load balancing among multiple fabric ports. A plurality of first values is received in response to receiving a first frame, wherein each of the first values is related to a quantity of data stored in a respective one of a plurality of buffers of fabric ports. First identifiers are also received, each of which corresponds to a respective one of a first subset of the plurality of buffers. A subset of the first identifiers is selected based on one or more of the first values. Thereafter one of the first identifiers contained in the selected subset is selected. Ultimately the first frame is transmitted to the buffer that corresponds to the selected one of the first identifiers.

摘要: In one embodiment, a programmable priority encoder is configured to receive inputs, including an ordered list of a plurality of input request values each representing either a request or a non-request, and a starting position within the ordered list of the plurality of input request values. The programmable priority encoder is configured to generate an identification of a result position of a first input indicating said request in order from a position identified from the starting position within the ordered list. In one embodiment, the programmable priority encoder includes a hierarchal structure of logic blocks including a plurality of columns of logic blocks; wherein a first-stage column of the plurality of columns of logic blocks is configured to operate on at most N input values; and wherein the ordered list of the plurality of input request values consists of N input request values.
