摘要： A method of generating access-control lists executable by a system and derived from access-control rules supplied for insuring security of an operation system is presented. The method includes the steps of inputting access-manager-type-group information, access-target-type-group information, and organizational-structure information, inputting access-control rules each comprised of an access-manager type, an access-target type, and an action in order to represent security guidelines of the system, inputting constraint conditions relating to the organizational structure of the system, extracting access managers and access targets from the access-manager-type-group information and the access-target-type-group information, respectively, with respect to the access-manager type and the access-target type included in each of the access-control rules, checking the constraint conditions with regard to all the combinations between the extracted access managers and the extracted access targets, and generating access-control lists comprised of such an access manager, an access target, and an action as to satisfy the constraint conditions.

摘要： A route switching system in a communications network constituted of a transmitter and a receiver connected by a plurality of routes for switching a first route along which communication is being held by transmission of cells to a second route causing no blocking. The route switching system comprises a first switch provided in the transmitter for switching input cells from one route to another and outputting the cells, a first storage portion provided in the transmitter for storing the input cells, a second switch provided in the receiver for switching input cells from one route to another and outputting the cells, and a second storage portion provided in the receiver for storing the input cells. At the time when the route is switched over, the first switch is changed over so that the cells are transmitted through the first storage portion and, on the receiver side, the second switch is changed over so that the cells transmitted over the second route are stored into the second storage portion. The transmitter includes a switching signal generating portion for outputting, at the time of route switching, a switching timing signal to the receiver side through the first switch, and the receiver includes a switching signal detecting portion for detecting the switching timing signal from the switching signal generating portion. When cells are stored into the first and second storage portions while the route is switched over, the cells are stored first into the second storage portion on the receiver side.

摘要： A cell loss ratio calculating method is a method of calculating a cell loss ratio of a buffer for storing call cells from a plurality of traffic sources and comprises a distribution expressing step, a number-of-average-arrivals expressing step, an average path calculating step and a cell loss ratio calculating step. In the distribution expressing step, a distribution of the number of cells accumulated within a time for which the cell passes the buffer is expressed by use of a Poisson distribution on an assured side. In the number-of-average-arrivals expressing step, the number-of-cells distribution is expressed with parameters representing a number of average arrivals of the Poisson distribution. In average path calculating step, an average path is calculated with respect to time-variations of a cell arrival ratio and a distribution of the cell arrival ratio. In the cell loss ratio calculating step, the cell loss ratio of the buffer is calculated by using a result of the calculation in the average path calculating step as well as by using a table for storing a precalculated value of a number-of-lost-cells expected value corresponding to each number of average arrivals.

摘要： A probability transition matrix S.sub.t is formulated that expresses a multiplexing process which includes nested threshold priority control and classified priority control. A state equation using the matrix S.sub.t is solved by substituting therein upper and lower bounds of a probability distribution of a cell arrival count a.sub.t in an average time series, to calculate a probability distribution of a cell length in a buffer. From the thus calculated cell length probability distribution, the QOS is evaluated on a priority class basis. Based on the QOS evaluation, optimization of call admission control and priority control is accomplished.
