摘要： An apparatus is described comprising an ingress port and a plurality of switch planes where each of the switch planes has a dedicated scheduler and each of the switch planes are communicatively coupled to the ingress port. The switch planes may further have at least one input control port and at least one output control port where each of the input control ports are coupled to each of the output control ports in a crossbar arrangement. The communicative coupling may further comprise one of the input control ports coupled to the ingress port. Furthermore, the ingress port may have at least one unicast queue which is dedicated to a specific egress port. The ingress port may also have a multicast queue. The dedicated scheduler may further comprise a pointer to determine priority between multicast and unicast traffic, a pointer to determine priority between contending input control ports having multicast traffic and/or a pointer for each of the output control ports to determine priority between contending input control ports having unicast traffic. The apparatus may also further comprise a plurality of ingress ports where each of the ingress ports are communicatively coupled to one of each of the input control ports.

摘要： A network cell is delayed by a predetermined time by injecting one or more delay cells ahead of the cell into a queue in a network (e.g., an ATM network). The queue may comprise a cell egress queue at a switch of the ATM network and the delay cells may be generated at the switch using a local processor. If required, additional cells may be generated by replicating the locally generated cells. The delay cells, including the replicated cells, may be stored together with the network cells in the queue; the number of delay cells so stored being controlled by configuring a threshold for the egress queue.

摘要： A switch node includes arbiter logic configured to gather global information regarding switching requests within the switch node and to control switching of one or more packets through the switch node. The arbiter logic may include a bus snooping interface configured to detect the switching requests within the switch node. The bus snooping interface includes a plurality of switching request destination registers configured to store switching request destination information from the detected switching requests. In addition, the arbiter logic includes a packet switching request array configured to transmit a next switching request within the switch node according to prior switching request destination information stored in the switching request destination registers. The switching of the one or more packets may be through a cross-point switch matrix in the switch node.

摘要： In a digital switch, incoming cells are placed into a queue in a cell memory. The switch maintains various cell queues, including VC queues that correspond to individual connections and QBin queues that correspond to various classes of service. Cells may arrive to a VC queue or a QBin queue but will depart from a QBin queue. Accordingly, cells may be moved from VC queues to QBin queues. Cells are serviced according to the use of QBin Groups. A QBin Group (QBG) includes a number of logical queues (QBins) of cells to be transported in the digital network. After a QBG is selected, one of its logical queues is selected for servicing. The QBG may be selected by examining all of the QBGs to find an eligible QBG which is most overdue for service. A QBin of the selected QBG may then be selected by examining each of the QBins comprising the selected QBG to find the most overdue for service. The QBGs may correspond to virtual interfaces.

摘要： A transaction for purchasable content is facilitated over an electronic network, wherein the purchasable content includes downloadable digital data. A first presence is maintained on the electronic network to which a consumer may connect. A first page is transmitted from the first presence to the consumer over the electronic network, such that the first page includes information concerning the purchasable content. A command is received from the consumer over the electronic network indicating that the consumer wishes the transaction for the purchasable content. The consumer is automatically linked to a second presence on the electronic network in response to the command such that the consumer may interact with the second presence over the electronic network to complete the transaction for the purchasable content.
