摘要： A method and apparatus for supplying new requests to a scheduler in an input-buffered multiport switch involve selecting a request that does not target output channels that conflict with output channels targeted by requests that are already accessible to the scheduler. Specifically, target output channels of requests that are presently accessible to the scheduler are identified and compared to target output channels of requests that are included in a queue of next-in-line requests. The queue of next-in-line requests is reviewed and the highest priority request having no conflicting output channels is supplied to the scheduler. By supplying the scheduler with a new request that targets non-conflicting output channels, the scheduler is presented with a wider range of requested output channels from which to choose in each arbitration cycle. In a first embodiment, one, two, or eight ports are connected to each one of four input/output controllers in a switch having a four-channel switch fabric. To supply the scheduler with new requests, secondary arbitration is performed on a channel-specific basis in order to supply channel-specific requests to the scheduler. The method of supplying requests to the scheduler can be scaled to include multiple channels and multiple packet priority designations.

摘要： A method and apparatus for managing a buffer memory in a packet switch that is shared between multiple ports in a network system. The apparatus comprises a plurality of slow data port interfaces (206) configured to transmit data at a first data rate between a slow dada port (202) and the buffer memory and a plurality of fast data port interfaces (208) configured to transmit data at a second data rate between a fast data port (220) and the buffer memory. A first level arbiter (210) is coupled to the plurality of slow data port interfaces. The first level arbiter chooses an access request of one of the slow data ports and outputs the access request. A second level arbiter (214) is coupled to the plurality of fast data port interfaces and to the output of the first level arbiter. The second level arbiter chooses an access request from among a plurality access requests from the fast data port interfaces and the access request from the first level arbiter, and forwards the chosen access request to the memory.

摘要： An input-buffered multipoint switch (60) having input channels (62, 64, 66 and 68) and output channels (72, 74, 76 and 78) includes multi-level request buffers (122, 124, 126 and 128), a data multiplexer (130), and a scheduler (132). The switch (60) has a distinct multi-level request buffer associated with each input channel and each request buffer has multiple request registers (160, 162, 164 and 166) for storing data cell transfer requests of different priorities. The multiple request registers (160, 162, 164 and 166) are linked in parallel to the scheduler (132) to allow arbitration among requests of different input channels and different priority levels.
