摘要： Disclosed is a method of generating pilot sequences having double lengths of slots used for frame synchronization in an up or down link of a next generation mobile communication system which adopts W-CDMA mode. Disclosed is a method of generating pilot sequences having double lengths of slots used for frame synchronization and defined by 4l+2(l=1,2,3, . . . ) while providing a mathematical method of generating code sequences of slot length. The method of generating pilot sequences having double lengths of slots used for frame synchronization includes the steps of selecting a bit length of pilot sequences used for frame synchronization, selecting a first code sequence indicative of a maximum correlation value at a specific delay point of a correlation period and indicative of a minimum correlation value at the other delay points excluding the specific delay point, selecting a second code sequence indicative of the same correlation characteristic as the selected code sequence, and combining the selected code sequences to generate pilot sequences having the selected bit length.

摘要： A packet switching network, e.g., the Internet, employs bandwidth managers to provide guaranteed bandwidth reservations to paired forwarding and receiving agents interfacing with sending and receiving stations in the transfer of large data files therebetween. The forwarding agents obtain guaranteed reservations from the bandwidth manager for segments of the large data file which are transmitted to the receiving station in accordance with the respective reservations. The receiving agent reassembles the segments into the large data file for delivery to the receiving station. By segmenting the large data files, using guaranteed bandwidth reservations on different links or multiple networks, the transmission of large data files through packet switching networks is accomplished without adversely impacting the service requirements of other network users. Reservations and concomitant transmissions are arranged up to the capacity of the network for the attachment which maximizes the transmission ability and allows the network to distribute the bandwidth usage to prevent network congestion.

摘要： A novel system and method of automatically detecting a change in network node connection in a multiport data switching system having receive ports for receiving data packets from network nodes, and a decision making engine for controlling data forwarding. Data blocks representing received data packets are placed in data queues corresponding to the receive ports. The data queues are transferred to logic circuitry for processing in accordance with a predetermined algorithm. This processing includes automatically detecting a change in connection between at least one of the network nodes and at least one of the receive ports, based on a search of an address table having address information relating to the receive ports. The address table may be searched for an address entry having a source address and VLAN address information that match a source address and VLAN address information of the received data packet. Receive port data written in the address entry having matching address information are checked to determine whether these data identify a receive port arranged in the same trunk as the receive port, from which the data packet is transferred. The address entry is automatically updated with new information, if the receive port identified in the address entry and the actual receive port are in different trunks.

摘要： A computer system may include one or more hosts and a plurality of data storage devices for providing multihop system calls. The data storage devices are interconnected and also connected to the one or more hosts. The connections may be direct or indirect. Each data storage device classifies a data operation as a system call, a remote system call, or a multihop system call. If an operation is classified as a multihop system call by a first data storage device, a portion of the data associated with the multihop system call is removed and a second portion of the data is forwarded to a second data storage device as specified by a connection identifier included in the first portion. A recursive process of removing a first portion and forwarding a second portion of data associated with the multihop system call is performed by each data storage device forwarded a second portion of data until a data storage device receives a second portion that is interpreted as a system call or a remote system call.

摘要： A method is presented which allows for the testing and verification of an off-line switch fabric used in network switch having redundant switch fabrics. A special test cell is directed to the off-line switch fabric, loops through a portion of the switching core of the off-line switch fabric, and is returned from the off-line switch fabric. A plurality of test cells can be used to provide full mesh connectivity checking of the off-line switch fabric. Testing is accomplished without need for reconfiguration of the off-line switch fabric, and the off-line switch fabric is available for use immediately upon determination of the need therefor.

摘要： The present invention relates to a switch for processing data units, such as IP data packets. The switch can be implemented as a router that includes a plurality of input ports, a plurality of output ports and a switch fabric capable of establishing logical pathways to interconnect a certain input port with a certain output port. A characterizing element of the router is its ability to control bandwidth usage on a basis of a logical pathway. This prevents congestion to occur in the switch fabric and also at the level of the output ports. For every active logical pathway the router sets-up a bandwidth control mechanism including at least one queue to hold data units received at an input port. The bandwidth control mechanism performs an accounting operation to determine the average bandwidth usage and if less than a threshold requests for releasing data units in the switch fabric are sent to the switch fabric controller. When the threshold is exceeded the bandwidth control mechanism stops sending requests for service to the switch fabric controller. The system also supports priorities. Instead of stopping the issuance of signals requesting release of data packets the priority level of the queue (reflected in a priority field in the signal requesting release of a data packet) changes from HI to LO. The switch fabric controller is designed to recognize priority requests and will accept LO priority requests only when there are no other HI priority requests pending. The present invention also provides a data transport device which includes a plurality of nodes interconnected by a physical link that establishes two ring-shaped paths on which data is transported on opposite directions. Each node is capable of sending a control message to the upstream node to advise the upstream node of the data carrying requirements of the node at which the message has originated. The upstream node can then throttle the introduction of data in the paths to preserve capacity that can be used by the downstream nodes.
