Abstract: 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.

Abstract: 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.

Abstract translation: 在数字交换机中，传入的信元被放入单元存储器中的队列中。 交换机维护各种小区队列，包括对应于各种连接的VC队列和对应于各种服务类别的QBin队列。 单元格可能会到达一个VC队列或一个QBin队列，但会离开QBin队列。 因此，小区可以从VC队列移动到QBin队列。 根据QBin组的使用对单元进行维修。 QBG组（QBG）包括在数字网络中要传输的单元的多个逻辑队列（QBins）。 选择QBG后，选择其逻辑队列之一进行维修。 QBG可以通过检查所有QBG来选择，以找到最适合服务的合格QBG。 然后可以通过检查包括所选择的QBG的每个QB，来查找所选择的QBG的QBin，以找到服务最迟。 QBG可以对应于虚拟接口。

Abstract: A method for operating a router which combines virtual channels is disclosed, where both forward and reverse directed resource management cells are used to control transmission rate of a source computer. The merging router receives forward directed resource management cells from a plurality of upstream routers, where each forward directed resource management cell represents a virtual channel. The router: (1) replies to each upstream router with a reverse directed resource management cell; and (2) forwards to a downstream router a combined forward directed resource management cell, the combined forward directed resource management cell combining a plurality of virtual channels established between the router and the plurality of upstream routers.

Abstract: 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.

Abstract: A method for cell replication in which a request for data transmission and mapping information are received by a crossbar and a scheduler and are sent by one of a plurality of software configurable slot remap registers. The mapping information is indicative of a destination slot and a backup destination slot to which the data is to be transmitted. The method replicates the data by transmitting the data to the destination slot and to the backup destination slot when the data arrives at an input slot of the crossbar.
