    摘要： A system and method for providing automatic path selection in a fiber-optic transmission network. The system provides efficient utilization of available bandwidth with respect to T1, T3 and STS-3c service requests. A time slot is selected from the available time slots in a maximally utilized and efficient manner in response to a type of service request. The time slot is then assigned to the service request to provide a transmission pathway. In response to a T1 service request, the system finds the most occupied time slot which has an available assignable time slot. If a new unoccupied time slot is required or the request is for a T3 or a STS-3c service, the system selects an unoccupied time slot in accordance with a prioritized order of contiguous unoccupied time slots.

    摘要： A data synchronization system, which in one embodiment, uses a ShuffleNet topology requiring an even number, N=2m, of nodes in the system. These nodes are organized into two sets, X=x.sub.0, . . . , x.sub.m-1 and Y=y.sub.0, . . . , y.sub.m-1, wherein the subscripts are always to be taken modulo m. Each "round" of communication entails simultaneously synchronizing the nodes in X with nodes in Y according to a matching between the two sets. The rounds are grouped into two "batches," batch B.sub.j which consists of rounds R.sub.2j-1 and R.sub.2j-2 for j.gtoreq.1. During each odd batch B.sub.2j-1, each x.sub.i synchronizes with y.sub.2i+2j-2 and with y.sub.2i+2j-1. In another embodiment, the data synchronization is based on a hypercube scheme, wherein each node is labeled by a binary string and any two nodes with their labels differing by one bit are connected by an edge and only adjacent nodes, i.e. those nodes connected by an edge, can communicate and exchange data directly according to an update schedule. In a third embodiment, a hypercube scheme is used, but the number of nodes is assumed to be a power of 2 or N=2.sup.m. This embodiment, like the second embodiment, uses the labeling of nodes by their binary representation, but the matchings of nodes used to determine the update schedule is not confined to the hypercube edges. Instead, a general cyclic matching scheme is used.

    摘要： A navigation system particularly adapted for ships making a passing within a harbor or the like, utilizing signal inputs from on-board vessel position determining equipment such as Loran or Decca apparatus and an on-board object detecting equipment such as a radar or sonar apparatus. The system further includes an on-board vessel position computer which operates in a differential Loran mode in response to observed Loran time differences, stored data from an initial calibration, and Loran grid offset data from an on-shore monitor system to compute a highly accurate current or present position fix in longitude and latitude whereupon the computer causes a predetermined electronic chart to be displayed in color on the screen of a cathode ray tube, being generated from a plurality of electronic charts stored in the form of digital files in memory. The selected chart, together with the present position of the ship, is displayed along with preselected alpha-numeric indicia of data relating to bearings, way points, ranges, "time to go", etc., also generated in accordance with the computed vessel position. Radar target returns of the local land mass and other stationary moving targets are additionally received by the ship's radar. The radar image of the target echoes is next referenced to and superimposed on the electronic chart generated; however, the radar's land mass echoes are suppressed in favor of the electronic chart land mass while displaying all other targets.

    摘要： We disclose a method for routing a set of demands in a ring network that comprises nodes interconnected by directed links, in which each demand may be routed clockwise or counterclockwise. According to our method, a linear program is solved to obtain a set of routing variables that minimize an objective function. Each routing variable corresponds to a respective one of the demands, and has a value, exemplarily, on the closed interval from 0 to 1. A value of 1 signifies, e.g., clockwise routing, and a value of 0 signifies counterclockwise routing. The objective function describes the value of a load, defined on each link and maximized over all links of the network, so that a solution of the linear program provides a minimum value of the maximized load. The method further comprises rounding the routing variables so that the value of each routing variable falls at 1 or 0. This rounding is carried out such that the maximized load does not exceed the previously-obtained minimum value of the maximized load. The method further comprises routing each of the demands clockwise or counterclockwise, in accordance with the value of its respective routing variable.

    摘要： A system and method are disclosed for time-domain wavelength interleaved networking that reduce the need for complex time-slot scheduling and reduce the routing complexity. Substantially all communications in the time-domain wavelength interleaved network pass through a hub node. In addition, interior nodes in the time-domain wavelength interleaved network will forward substantially all communications received from the hub node that are destined for another node on all branches outward from the hub node. The central hub node can impose a timing reference. Thus, the transmission and reception of a message can be synchronized such that a message sent in a time-slot k by a node Ni will be received by a node Nj in the time-slot k. Further, the hub node can recover from a link failure by shifting transmission times of all nodes that are separated from the hub node by the failed link.
