摘要： A method and apparatus for managing the flow of data within a switching device is provided. The switching device includes network interface cards connected to a common backplane. Each interface card is configured to support the maximum transfer rate of the backplane by maintaining a “pending” queue to track data that has been received but for which the appropriate routing destination has not yet been determined. The switching device includes a switch controller that maintains a central card/port-to-address table. When an interface card receives data with a destination address that is not known to the interface card, the interface card performs a direct memory access over a bus that is separate from the backplane to read routing data directly from the central table in the switch controller. Each interface card builds and maintains a routing information table in its own local memory that only includes routing information for the destination addresses that the interface card is most likely to receive.

摘要： The switch fabric of the ATM switch, i.e., the ATM switch backplane bus, switches a cell based on routing information provided by the source LAN or ATM module to an output port on a destination LAN or ATM module of the switching hub. In the described system, the ATM switch is preconfigured to provide a fully connected topology between ports of all modules. In one embodiment, ATM cells transmitted across the ATM switch fabric between a source LAN or ATM module and a destination LAN module, e.g., Token Ring, FDDI or Ethernet, is accomplished by way of a routing tag prepended on the ATM cells. The routing tag provides both unicast and multicast group destination information such that the ATM cells are routed to the appropriate port on a given destination module without the need to establish a virtual circuit between the source module and the destination module using VPI/VCIs.
摘要翻译： ATM交换机的交换结构，即ATM交换机背板总线，根据由源LAN或ATM模块提供的路由信息将小区切换到交换集线器的目的地LAN或ATM模块上的输出端口。在所描述的系统中，ATM交换机被预配置为在所有模块的端口之间提供完全连接的拓扑。在一个实施例中，通过在ATM信元上提供的路由标签来实现通过ATM交换结构在源LAN或ATM模块与目的地LAN模块（例如，令牌环，FDDI或以太网）之间传输的ATM信元。路由标签提供单播和多播组目的地信息，使得ATM信元被路由到给定目的地模块上的适当端口，而不需要使用VPI / VCI在源模块和目的地模块之间建立虚拟电路。

摘要： Communication traffic management systems and methods are disclosed. One or more traffic managers may be provided for managing communication traffic to be sent toward respective groups of one or more destinations. A determination is made as to whether one traffic manager or more than one traffic manager is provided. If one traffic manager is provided, then communication traffic is transferred to the traffic manager. In the case where more than one traffic manager is provided, received communication traffic is transferred to a traffic manager for a destination toward which the communication traffic is to be sent. Traffic managers may be added to or removed from communication equipment to provide varying levels of traffic management.

摘要： Bounding cell reorder depth is disclosed. It is determined whether a reorder buffer that is associated with a switch fabric exceeds a depth limit. In the event that the reorder buffer exceeds the depth limit, backpressure with respect to a source associated with the reorder buffer is sent. In such cases source based back pressure information is included in a reserved field in a cell that is being sent into the switch fabric. In the event that the reorder buffer does not exceed the depth limit, the cell is sent to the switch fabric. In such cases the reserved field is present in the cell but is unused.
