    摘要： Method of managing priority during the transmission of a message, in an interconnections network comprising at least one transmission agent which comprises at least one input and at least one output, each input comprising a means of storage organized as a queue of messages. A message priority is assigned during the creation of the message, and a queue priority equal to the maximum of the priorities of the messages of the queue is assigned to at least one queue of messages of an input. A link priority is assigned to a link linking an output of a first transmission agent to an input of a second transmission agent, equal to the maximum of the priorities of the queues of messages of the inputs of said first agent comprising a first message destined for that output of said first agent which is coupled to said link, and the priority of the link is transmitted to that input of said second agent which is coupled to the link.

    摘要： A pipeline scheduler provides a minimum bandwidth guarantee by transporting cells from an input port to an output port in a two-phased approach. Cells that conform to a minimum cell rate (MCR) are selected from queues at the input port and arranged into supercells for transport to the output port, followed by nonconforming cells, to guarantee fairness by using scheduling modules to build the supercells first for conforming cells, and then for nonconforming cells. Reservation vectors are used to permit the same time slot of the next frame to be reserved by a first queue, and the same time slot of the following time frame to be held for reservation by a second queue, to ensure equal time slot access by the first and second queues over successive time frames.

    摘要： Apparatus for flexible sharing of bandwidth in switches with input buffering by dividing time into a plurality of frames of time slots, wherein each frame has a specified integer value of time slots. The apparatus includes modules where inputs sequentially select available outputs to which the inputs send packets in specified future time slots. The selection of outputs by the inputs is done using a pipeline technique and a schedule is calculated within multiple time slots.

    摘要： Priority-biased compound arbitration at a switching fabric ingress. The ingress includes a plurality of ingress queues and a priority-biased arbitration engine configured to arbitrate between the ingress queues. The ingress further includes exit first-in-first-out queues (FIFOs) configured to forward cells from the ingress queues to a switching fabric and a throughput-biased arbitration engine configured to arbitrate between the exit FIFOs.

    摘要： Systems and methods for switching communications across different data link layer protocols are provided. A switch which supports a first data link layer protocol can support differentiated services for a second data link layer protocol without performing routing in the second data link layer protocol. The differentiated services are provided by mapping a connection of the first data link layer protocol onto one of a plurality of connections of a second data link layer protocol. The mapping of frames is based on the connection carrying the frames of the first data link layer protocol and a type of service associated with the frames. The frames of the first data link layer protocol are forwarded to another switch using one of a plurality of connections based on the mapping.
