    摘要: A cross-bar switch includes a set of input ports to receive data packets and a set of sink ports in communication with the input ports to receive the data packets and forward them onto a communications link. Each sink port is adapted to concurrently receive multiple data packets targeted to the same destination or multiple destinations. For example, one sink port receives a first data packet and a second data packet. The one sink port receives at least a portion of the second data packet during a time period in which the one sink port is receiving the first data packet.

    摘要: A cross-bar switch includes a set of input ports and a set of sink ports in communication with the input ports. The input ports receive packets, which are snooped by the sink ports. The cross-bar switch also includes a set of port address tables. Each port address table is adapted to store data identifying a plurality of destinations supported by a sink port. For example, a first port address table is adapted to identify a plurality of destinations supported by a first sink port in the set of sink ports. When determining whether to accept a packet, a sink port considers whether the packet's destination is identified in the sink port's port address table. By supporting multiple destinations, a port address table implicitly facilitates a sink port's multicast operation.

    摘要: A computer network method and apparatus. The present invention comprises a computer network having one or more hubs, each hub comprising one or more connection means for connection of computing devices to the network. Each connection means comprising a first interface means for coupling with a computing device, a second interface means for coupling with the network and a protocol processing means. The protocol processing means receives message packets and, depending on the message type, processing the message as either a network control message or a data transfer message. The present invention provides for "flow through" of data in the case of data transfer messages. The present invention further provides for calculation of checksum bytes as a data packet is received by the protocol processing means.

    摘要: An architecture for controlling a multiprocessing system to provide at least one network service to subscriber data packets transmitted in the system using a plurality of compute elements, comprising a management compute element including service set-up information for at least one service and at least one processing compute element applying said at least one network service to said data packets and communicating service set-up information with the management compute element in order to perform service specific operations on data packets. In a further embodiment, a method of controlling a processing system including a plurality of processors is disclosed. The method comprises the steps of operating at least one of said processors as a control authority providing service provisioning information for a subscriber; and operating a set of processors as a service specific compute element responsive to the control authority, receiving provisioning information from the subscriber and performing service specific instructions on data packets to provide IP content services.

    摘要: A cross-bar switch includes a set of input ports for receiving data packets and a set of sink ports for transmitting the received packets to identified targets. A set of data rings couples the input ports to the sink ports. Each sink port utilizes the set of data rings to simultaneously accept multiple data packets targeted to the same destination—creating a non-blocking cross-bar switch. Sink ports are also each capable of supporting multiple targets—providing the cross-bar switch with implicit multicast capability.
